Falling in Love Part 7

Are the great animals now pa.s.sing away and leaving no representatives of their greatness to future ages? On land at least that is very probable. Man, diminutive man, who, if he walked on all fours, would be no bigger than a silly sheep, and who only partially disguises his native smallness by his acquired habit of walking erect on what ought to be his hind legs-man has upset the whole balanced economy of nature, and is everywhere expelling and exterminating before him the great herbivores, his predecessors. He needs for his corn and his bananas the fruitful plains which were once laid down in prairie or scrubwood. Hence it seems not unlikely that the elephant, the hippopotamus, the rhinoceros, and the buffalo must go. But we are still a long way off from that final consummation, even on dry land; while as for the water, it appears highly probable that there are as good fish still in the sea as ever came out of it. Whether man himself, now become the sole dominant animal of our poor old planet, will ever develop into t.i.tanic proportions, seems far more problematical. The race is now no longer to the swift, nor the battle to the strong. Brain counts for more than muscle, and mind has gained the final victory over mere matter. Goliath of Gath has shrunk into insignificance before the Gatling gun; as in the fairy tales of old, it is cunning little Jack with his clever devices who wins the day against the heavy, clumsy, muddle-headed giants. Nowadays it is our 'Minotaurs' and 'Warriors' that are the real leviathans and behemoths of the great deep; our Krupps and Armstrongs are the fire-breathing krakens of the latter-day seas. Instead of developing individually into huge proportions, the human race tends rather to aggregate into vast empires, which compete with one another by means of huge armaments, and invent mitrailleuses and torpedos of incredible ferocity for their mutual destruction. The dragons of the prime that tare each other in their slime have yielded place to eighty-ton guns and armour-plated turret-s.h.i.+ps. Those are the genuine lineal representatives on our modern seas of the secondary saurians. Let us hope that some coming geologist of the dim future, finding the fossil remains of the sunken 'Captain,' or the plated scales of the 'Comte de Gra.s.se,' firmly embedded in the upheaved ooze of the existing Atlantic, may shake his head in solemn deprecation at the horrid sight, and thank heaven that such hideous carnivorous creatures no longer exist in his own day.

FOSSIL FOOD

There is something at first sight rather ridiculous in the idea of eating a fossil. To be sure, when the frozen mammoths of Siberia were first discovered, though they had been dead for at least 80,000 years (according to Dr. Croll's minimum reckoning for the end of the great ice age), and might therefore naturally have begun to get a little musty, they had nevertheless been kept so fresh, like a sort of prehistoric Australian mutton, in their vast natural refrigerators, that the wolves and bears greedily devoured the precious relics for which the naturalists of Europe would have been ready gladly to pay the highest market price of best beefsteak. Those carnivorous vandals gnawed off the skin and flesh with the utmost appreciation, and left nothing but the tusks and bones to adorn the galleries of the new Natural History Museum at South Kensington. But then wolves and bears, especially in Siberia, are not exactly fastidious about the nature of their meat diet. Furthermore, some of the bones of extinct animals found beneath the stalagmitic floor of caves, in England and elsewhere, presumably of about the same age as the Siberian mammoths, still contain enough animal matter to produce a good strong stock for antediluvian broth, which has been scientifically described by a high authority as pre-Adamite jelly. The congress of naturalists at Tubingen a few years since had a smoking tureen of this cave-bone soup placed upon the dinner-table at their hotel one evening, and p.r.o.nounced it with geological enthusiasm 'scarcely inferior to prime ox-tail.' But men of science, too, are accustomed to trying unsavoury experiments, which would go sadly against the grain with less philosophic and more squeamish palates. They think nothing of tasting a caterpillar that birds will not touch, in order to discover whether it owes its immunity from attack to some nauseous, bitter, or pungent flavouring; and they even advise you calmly to discriminate between two closely similar species of snails by trying which of them when chewed has a delicate soupcon of oniony aroma. So that naturalists in this matter, as the children say, don't count: their universal thirst for knowledge will prompt them to drink anything, down even to consomme of quaternary cave-bear.

There is one form of fossil food, however, which appears constantly upon all our tables at breakfast, lunch, and dinner, every day, and which is so perfectly familiar to every one of us that we almost forget entirely its immensely remote geological origin. The salt in our salt-cellars is a fossil product, laid down ages ago in some primaeval Dead Sea or Caspian, and derived in all probability (through the medium of the grocer) from the tria.s.sic rocks of Ches.h.i.+re or Worcesters.h.i.+re. Since that thick bed of rock-salt was first precipitated upon the dry floor of some old evaporated inland sea, the greater part of the geological history known to the world at large has slowly unrolled itself through incalculable ages. The dragons of the prime have begun and finished their long (and Lord Tennyson says slimy) race. The fish-like saurians and flying pterodactyls of the secondary period have come into existence and gone out of it gracefully again. The whole family of birds has been developed and diversified into its modern variety of eagles and t.i.tmice. The beasts of the field have pa.s.sed through sundry stages of mammoth and mastodon, of sabre-toothed lion and huge rhinoceros. Man himself has progressed gradually from the humble condition of a 'hairy arboreal quadruped'-these bad words are Mr. Darwin's own-to the glorious elevation of an erect, two-handed creature, with a county suffrage question and an intelligent interest in the latest proceedings of the central divorce court. And after all those manifold changes, compared to which the entire period of English history, from the landing of Julius Caesar to the appearance of this present volume (to take two important landmarks), is as one hour to a human lifetime, we quietly dig up the salt to-day from that dry lake bottom and proceed to eat it with the eggs laid by the hens this morning for this morning's breakfast, just as though the one food-stuff were not a whit more ancient or more dignified in nature than the other. Why, mammoth steak is really quite modern and common-place by the side of the salt in the salt-cellar that we treat so cavalierly every day of our ephemeral existence.

The way salt got originally deposited in these great rock beds is very well ill.u.s.trated for us by the way it is still being deposited in the evaporating waters of many inland seas. Every schoolboy knows of course (though some persons who are no longer schoolboys may just possibly have forgotten) that the Caspian is in reality only a little bit of the Mediterranean, which has been cut off from the main sea by the gradual elevation of the country between them. For many ages the intermediate soil has been quite literally rising in the world; but to this day a continuous chain of salt lakes and marshes runs between the Caspian and the Black Sea, and does its best to keep alive the memory of the time when they were both united in a single basin. All along this intervening tract, once sea but now dry land, banks of sh.e.l.ls belonging to kinds still living in the Caspian and the Black Sea alike testify to the old line of water communication. One fine morning (date unknown) the intermediate belt began to rise up between them; the water was all pushed off into the Caspian, but the sh.e.l.ls remained to tell the tale even unto this day.

Now, when a bit of the sea gets cut off in this way from the main ocean, evaporation of its waters generally takes place rather faster than the return supply of rain by rivers and lesser tributaries. In other words, the inland sea or salt lake begins slowly to dry up. This is now just happening in the Caspian, which is in fact a big pool in course of being slowly evaporated. By-and-by a point is reached when the water can no longer hold in solution the amount of salts of various sorts that it originally contained. In the technical language of chemists and physicists it begins to get supersaturated. Then the salts are thrown down as a sediment at the bottom of the sea or lake, exactly as crust formed on the bottom of a kettle. Gypsum is the first material to be so thrown down, because it is less soluble than common salt, and therefore sooner got rid of. It forms a thick bottom layer in the bed of all evaporating inland seas; and as plaster of Paris it not only gives rise finally to artistic monstrosities hawked about the streets for the degradation of national taste, but also plays an important part in the manufacture of bonbons, the destruction of the human digestion, and the ultimate ruin of the dominant white European race. Only about a third of the water in a salt lake need be evaporated before the gypsum begins to be deposited in a solid layer over its whole bed; it is not till 93 per cent. of the water has gone, and only 7 per cent. is left, that common salt begins to be thrown down. When that point of intensity is reached, the salt, too, falls as a sediment to the bottom, and there overlies the gypsum deposit. Hence all the world over, wherever we come upon a bed of rock salt, it almost invariably lies upon a floor of solid gypsum.

The Caspian, being still a very respectable modern sea, constantly supplied with fresh water from the surrounding rivers, has not yet begun by any means to deposit salt on its bottom from its whole ma.s.s; but the shallow pools and long bays around its edge have crusts of beautiful rose-coloured salt-crystals forming upon their sides; and as these lesser basins gradually dry up, the sand, blown before the wind, slowly drifts over them, so as to form miniature rock-salt beds on a very small scale. Nevertheless, the young and vigorous Caspian only represents the first stage in the process of evaporation of an inland sea. It is still fresh enough to form the abode of fish and mollusks; and the irrepressible young lady of the present generation is perhaps even aware that it contains numbers of seals, being in fact the seat of one of the most important and valuable seal-fisheries in the whole world. It may be regarded as a typical example of a yet youthful and lively inland sea.

The Dead Sea, on the other hand, is an old and decrepit salt lake in a very advanced state of evaporation. It lies several feet below the level of the Mediterranean, just as the Caspian lies several feet below the level of the Black Sea; and as in both cases the surface must once have been continuous, it is clear that the water of either sheet must have dried up to a very considerable extent. But, while the Caspian has shrunk only to 85 feet below the Black Sea, the Dead Sea has shrunk to the enormous depth of 1,292 feet below the Mediterranean. Every now and then, some enterprising De Lesseps or other proposes to dig a ca.n.a.l from the Mediterranean to the Dead Sea, and so re-establish the old high level. The effect of this very revolutionary proceeding would be to flood the entire Jordan Valley, connect the Sea of Galilee with the Dead Sea, and play the d.i.c.kens generally with Scripture geography, to the infinite delight of Sunday school cla.s.ses. Now, when the Dead Sea first began its independent career as a separate sheet of water on its own account, it no doubt occupied the whole bed of this imaginary engineers' lake-spreading, if not from Dan to Beersheba, at any rate from Dan to Edom, or, in other words, along the whole Jordan Valley from the Sea of Galilee and even the Waters of Merom to the southern desert. (I will not insult the reader's intelligence and orthodoxy by suggesting that perhaps he may not be precisely certain as to the exact position of the Waters of Merom; but I will merely recommend him just to refresh his memory by turning to his atlas, as this is an opportunity which may not again occur.) The modern Dead Sea is the last shrunken relic of such a considerable ancient lake. Its waters are now so very concentrated and so very nasty that no fish or other self-respecting animal can consent to live in them; and so buoyant that a man can't drown himself, even if he tries, because the sea is saturated with salts of various sorts till it has become a kind of soup or porridge, in which a swimmer floats, will he nill he. Persons in the neighbourhood who wish to commit suicide are therefore obliged to go elsewhere: much as in Tasmania, the healthiest climate in the world, people who want to die are obliged to run across for a week to Sydney or Melbourne.

The waters of the Dead Sea are thus in the condition of having already deposited almost all their gypsum, as well as the greater part of the salt they originally contained. They are, in fact, much like sea water which has been boiled down till it has reached the state of a thick salty liquid; and though most of the salt is now already deposited in a deep layer on the bottom, enough still remains in solution to make the Dead Sea infinitely salter than the general ocean. At the same time, there are a good many other things in solution in sea water besides gypsum and common salt; such as chloride of magnesia sulphate of pota.s.sium, and other interesting substances with pretty chemical names, well calculated to endear them at first sight to the sentimental affections of the general public. These other by-contents of the water are often still longer in getting deposited than common salt; and, owing to their intermixture in a very concentrated form with the mother liquid of the Dead Sea, the water of that evaporating lake is not only salt but also slimy and fetid to the last degree, its taste being accurately described as half brine, half rancid oil. Indeed, the salt has been so far precipitated already that there is now five times as much chloride of magnesium left in the water as there is common salt. By the way, it is a lucky thing for us that these various soluble minerals are of such const.i.tution as to be thrown down separately at different stages of concentration in the evaporating liquid; for, if it were otherwise, they would all get deposited together, and we should find on all old salt lake beds only a mixed layer of gypsum, salt, and other chlorides and sulphates, absolutely useless for any practical human purpose. In that case, we should be entirely dependent upon marine salt pans and artificial processes for our entire salt supply. As it is, we find the materials deposited one above another in regular layers; first, the gypsum at the bottom; then the rock-salt; and last of all, on top, the more soluble mineral const.i.tuents.

The Great Salt Lake of Utah, sacred to the memory of Brigham Young, gives us an example of a modern saline sheet of very different origin, since it is in fact not a branch of the sea at all, but a mere shrunken remnant of a very large fresh-water lake system, like that of the still-existing St. Lawrence chain. Once upon a time, American geologists say, a huge sheet of water, for which they have even invented a definite name, Lake Bonneville, occupied a far larger valley among the outliers of the Rocky Mountains, measuring 300 miles in one direction by 180 miles in the other. Beside this primitive Superior lay a second great sheet-an early Huron-(Lake Lahontan, the geologists call it) almost as big, and equally of fresh water. By-and-by-the precise dates are necessarily indefinite-some change in the rainfall, unregistered by any contemporary 'New York Herald,' made the waters of these big lakes shrink and evaporate. Lake Lahontan shrank away like Alice in Wonderland, till there was absolutely nothing left of it; Lake Bonneville shrank till it attained the diminished size of the existing Great Salt Lake. Terrace after terrace, running in long parallel lines on the sides of the Wahsatch Mountains around, mark the various levels at which it rested for awhile on its gradual downward course. It is still falling indeed; and the plain around is being gradually uncovered, forming the white salt-encrusted sh.o.r.e with which all visitors to the Mormon city are so familiar.

But why should the water have become briny? Why should the evaporation of an old Superior produce at last a Great Salt Lake? Well, there is a small quant.i.ty of salt in solution even in the freshest of lakes and ponds, brought down to them by the streams or rivers; and, as the water of the hypothetical Lake Bonneville slowly evaporated, the salt and other mineral const.i.tuents remained behind. Thus the solution grew constantly more and more concentrated, till at the present day it is extremely saline. Professor Geikie (to whose works the present paper is much indebted) found that he floated on the water in spite of himself; and the under sides of the steps at the bathing-places are all encrusted with short stalact.i.tes of salt, produced from the drip of the bathers as they leave the water. The mineral const.i.tuents, however, differ considerably in their proportions from those found in true salt lakes of marine origin; and the point at which the salt is thrown down is still far from having been reached. Great Salt Lake must simmer in the sun for many centuries yet before the point arrives at which (as cooks say) it begins to settle.

That is the way in which deposits of salt are being now produced on the world's surface, in preparation for that man of the future who, as we learn from a duly const.i.tuted authority, is to be hairless, toothless, web-footed, and far too respectable ever to be funny. Man of the present derives his existing salt-supply chiefly from beds of rock-salt similarly laid down against his expected appearance some hundred thousand aeons or so ago. (An aeon is a very convenient geological unit indeed to reckon by; as n.o.body has any idea how long it is, they can't carp at you for a matter of an aeon or two one way or the other.) Rock-salt is found in most parts of the world, in beds of very various ages. The great Salt Range of the Punjaub is probably the earliest in date of all salt deposits; it was laid down at the bottom of some very ancient Asiatic Mediterranean, whose last shrunken remnant covered the upper basin of the Indus and its tributaries during the Silurian age. Europe had then hardly begun to be; and England was probably still covered from end to end by the primaeval ocean. From this very primitive salt deposit the greater part of India and Central Asia is still supplied; and the Indian Government makes a pretty penny out of the dues in the shape of the justly detested salt-tax-a tax especially odious because it wrings the fraction of a farthing even from those unhappy agricultural labourers who have never tasted ghee with their rice.

The thickness of the beds in each salt deposit of course depends entirely upon the area of the original sea or salt-lake, and the length of time during which the evaporation went on. Sometimes we may get a mere film of salt; sometimes a solid bed six hundred feet thick. Perfectly pure rock-salt is colourless and transparent; but one doesn't often find it pure. Alas for a degenerate world! even in its original site, Nature herself has taken the trouble to adulterate it beforehand. (If she hadn't done so, one may be perfectly sure that commercial enterprise would have proved equal to the occasion in the long run.) But the adulteration hasn't spoilt the beauty of the salt; on the contrary, it serves, like rouge, to give a fine fresh colour where none existed. When iron is the chief colouring matter, rock-salt a.s.sumes a beautiful clear red tint; in other cases it is emerald green or pale blue. As a rule, salt is prepared from it for table by a regular process; but it has become a fad of late with a few people to put crystals of native rock-salt on their tables; and they decidedly look very pretty, and have a certain distinctive flavour of their own that is not unpleasant.

Our English salt supply is chiefly derived from the Ches.h.i.+re and Worcesters.h.i.+re salt-regions, which are of tria.s.sic age. Many of the places at which the salt is mined have names ending in wich, such as Northwich, Middlewich, Nantwich, Droitwich, Netherwich, and s.h.i.+rleywich. This termination wich is itself curiously significant, as Canon Isaac Taylor has shown, of the necessary connection between salt and the sea. The earliest known way of producing salt was of course in shallow pans on the sea-sh.o.r.e, at the bottom of a shoal bay, called in Norse and Early English a wick or wich; and the material so produced is still known in trade as bay-salt. By-and-by, when people came to discover the inland brine-pits and salt mines, they transferred to them the familiar name, a wich; and the places where the salt was manufactured came to be known as wych-houses. Droitwich, for example, was originally such a wich, where the droits or dues on salt were paid at the time when William the Conqueror's commissioners drew up their great survey for Domesday Book. But the good, easy-going mediaeval people who gave these quaint names to the inland wiches had probably no idea that they were really and truly dried-up bays, and that the salt they mined from their pits was genuine ancient bay-salt, the deposit of an old inland sea, evaporated by slow degrees a countless number of ages since, exactly as the Dead Sea and the Great Salt Lake are getting evaporated in our own time.

Such, nevertheless, is actually the case. A good-sized Caspian used to spread across the centre of England and north of Ireland in tria.s.sic times, bounded here and there, as well as Dr. Hull can make out, by the Welsh Mountains, the Cheviots, and the Donegal Hills, and with the Peak of Derbys.h.i.+re and the Isle of Man standing out as separate islands from its blue expanse. (We will beg the question that the English seas were then blue. They are certainly marked so in a very fine cerulean tint on Dr. Hull's map of Tria.s.sic Britain.) Slowly, like most other inland seas, this early British Caspian began to lose weight and to shrivel away to ever smaller dimensions. In Devons.h.i.+re, where it appears to have first dried up, we get no salt, but only red marl, with here and there a cubical cast, filling a hole once occupied by rock-salt, though the percolation of the rain has long since melted out that very soluble substance, and replaced it by a mere mould in the characteristic square shape of salt crystals. But Worcesters.h.i.+re and Ches.h.i.+re were the seat of the inland sea when it had contracted to the dimensions of a mere salt lake, and begun to throw down its dissolved saline materials. One of the Ches.h.i.+re beds is sometimes a hundred feet thick of almost pure and crystalline rock-salt. The absence of fossils shows that animals must have had as bad a time of it there as in the Dead Sea of our modern Palestine. The Droitwich brine-pits have been known for many centuries, since they were worked (and taxed) even before the Norman Conquest, as were many other similar wells elsewhere. But the actual mining of rock-salt as such in England dates back only as far as the reign of King Charles II. of blessed memory, or more definitely to the very year in which the 'Pilgrim's Progress' was conceived and written by John Bunyan. During that particular summer, an enterprising person at Nantwich had sunk a shaft for coal, which he failed to find; but on his way down he came unexpectedly across the bed of rock-salt, then for the first time discovered as a native mineral. Since that fortunate accident the beds have been so energetically worked and the springs so energetically pumped that some of the towns built on top of them have got undermined, and now threaten from year to year, in the most literal sense, to cave in. In fact, one or two subsidences of considerable extent have already taken place, due in part no doubt to the dissolving action of rain water, but in part also to the mode of working. The mines are approached by a shaft; and, when you get down to the level of the old sea bottom, you find yourself in a sort of artificial gallery, whose roof, with all the world on top of it, is supported every here and there by ma.s.sive pillars about fifteen feet thick. Considering that the salt lies often a hundred and fifty yards deep, and that these pillars have to bear the weight of all that depth of solid rock, it is not surprising that subsidences should sometimes occur in abandoned shafts, where the water is allowed to collect, and slowly dissolve away the supporting columns.

Salt is a necessary article of food for animals, but in a far less degree than is commonly supposed. Each of us eats on an average about ten times as much salt as we actually require. In this respect popular notions are as inexact as in the very similar case of the supply of phosphorus. Because phosphorus is needful for brain action, people jump forthwith to the absurd conclusion that fish and other foods rich in phosphates ought to be specially good for students preparing for examination, great thinkers, and literary men. Mark Twain indeed once advised a poetical aspirant, who sent him a few verses for his critical opinion, that fish was very feeding for the brains; he would recommend a couple of young whales to begin upon. As a matter of fact, there is more phosphorus in our daily bread than would have sufficed Shakespeare to write 'Hamlet,' or Newton to discover the law of gravitation. It isn't phosphorus that most of us need, but brains to burn it in. A man might as well light a fire in a carriage, because coal makes an engine go, as hope to mend the pace of his dull pate by eating fish for the sake of the phosphates.

The question still remains, How did the salt originally get there? After all, when we say that it was produced, as rock-salt, by evaporation of the water in inland seas, we leave unanswered the main problem, How did the brine in solution get into the sea at all in the first place? Well, one might almost as well ask, How did anything come to be upon the earth at any time, in any way? How did the sea itself get there? How did this planet swim into existence at all? In the Indian mythology the world is supported upon the back of an elephant, who is supported upon the back of a tortoise; but what the tortoise in the last resort is supported upon the Indian philosophers prudently say not. If we once begin thus pus.h.i.+ng back our inquiries into the genesis of the cosmos, we shall find our search retreating step after step ad infinitum. The negro preacher, describing the creation of Adam, and drawing slightly upon his imagination, observed that when our prime forefather first came to consciousness he found himself 'sot up agin a fence.' One of his hearers ventured sceptically to e.j.a.c.u.l.a.t.e, 'Den whar dat fence come from, ministah?' The outraged divine scratched his grey wool reflectively for a moment, and replied, after a pause, with stern solemnity, 'Tree more ob dem questions will undermine de whole system ob teology.'

However, we are not permitted humbly to imitate the prudent reticence of the Indian philosophers. In these days of evolution hypotheses, and nebular theories, and kinetic energy, and all the rest of it, the question why the sea is salt rises up irrepressible and imperatively demands to get itself answered. There was a sapient inquirer, recently deceased, who had a short way out of this difficulty. He held that the sea was only salt because of all the salt rivers that run into it. Considering that the salt rivers are themselves salted by pa.s.sing through salt regions, or being fed by saline springs, all of which derive their saltness from deposits laid down long ago by evaporation from earlier seas or lake basins, this explanation savours somewhat of circularity. It amounts in effect to saying that the sea is salt because of the large amount of saline matter which it holds in solution. Cheese is also a caseous preparation of milk; the duties of an archdeacon are to perform archidiaconal functions; and opium puts one to sleep because it possesses a soporific virtue.

Apart from such purely verbal explanations of the saltness of the sea, however, one can only give some such account of the way it came to be 'the briny' as the following:-

This world was once a haze of fluid light, as the poets and the men of science agree in informing us. As soon as it began to cool down a little, the heavier materials naturally sank towards the centre, while the lighter, now represented by the ocean and the atmosphere, floated in a gaseous condition on the outside. But the great envelope of vapour thus produced did not consist merely of the const.i.tuents of air and water; many other gases and vapours mingled with them, as they still do to a far less extent in our existing atmosphere. By-and-by, as the cooling and condensing process continued, the water settled down from the condition of steam into one of a liquid at a dull red heat. As it condensed, it carried down with it a great many other substances, held in solution, whose component elements had previously existed in the primitive gaseous atmosphere. Thus the early ocean which covered the whole earth was in all probability not only very salt, but also quite thick with other mineral matters close up to the point of saturation. It was full of lime, and raw flint, and sulphates, and many other miscellaneous bodies. Moreover, it was not only just as salt as at the present day, but even a great deal salter. For from that time to this evaporation has constantly been going on in certain shallow isolated areas, laying down great beds of gypsum and then of salt, which still remain in the solid condition, while the water has, of course, been correspondingly purified. The same thing has likewise happened in a slightly different way with the lime and flint, which have been separated from the water chiefly by living animals, and afterwards deposited on the bottom of the ocean in immense layers as limestone, chalk, sandstone, and clay.

Thus it turns out that in the end all our sources of salt-supply are alike ultimately derived from the briny ocean. Whether we dig it out as solid rock-salt from the open quarries of the Punjaub, or pump it up from brine-wells sunk into the tria.s.sic rocks of Ches.h.i.+re, or evaporate it direct in the salt-pans of England and the shallow salines of the Mediterranean sh.o.r.e, it is still at bottom essentially sea-salt. However distant the connection may seem, our salt is always in the last resort obtained from the material held in solution in some ancient or modern sea. Even the saline springs of Canada and the Northern States of America, where the wapiti love to congregate, and the n.o.ble hunter lurks in the thicket to murder them unperceived, derive their saltness, as an able Canadian geologist has shown, from the thinly scattered salts still retained among the sediments of that very archaic sea whose precipitates form the earliest known life-bearing rocks. To the Homeric Greek, as to Mr. d.i.c.k Swiveller, the ocean was always the briny: to modern science, on the other hand (which neither of those worthies would probably have appreciated at its own valuation), the briny is always the oceanic. The fossil food which we find to-day on all our dinner-tables dates back its origin primarily to the first seas that ever covered the surface of our planet, and secondarily to the great rock deposits of the dried-up tria.s.sic inland sea. And yet even our men of science habitually describe that ancient mineral as common salt.

OGBURY BARROWS

We went to Ogbury Barrows on an archaeological expedition. And as the very name of archaeology, owing to a serious misconception incidental to human nature, is enough to deter most people from taking any further interest in our proceedings when once we got there, I may as well begin by explaining, for the benefit of those who have never been to one, the method and manner of an archaeological outing.

The first thing you have to do is to catch your secretary. The genuine secretary is born, not made; and therefore you have got to catch him, not to appoint him. Appointing a secretary is pure vanity and vexation of spirit; you must find the right man made ready to your hand; and when you have found him you will soon see that he slips into the onerous duties of the secretariat as if to the manner born, by pure instinct. The perfect secretary is an urbane old gentleman of mature years and portly bearing, a dignified representative of British archaeology, with plenty of money and plenty of leisure, possessing a heaven-born genius for organisation, and utterly unhampered by any foolish views of his own about archaeological research or any other kindred subject. The secretary who archaeologises is lost. His business is not to discourse of early English windows or of palaeolithic hatchets, of buried villas or of Plantagenet pedigrees, of Roman tile-work or of dolichocephalic skulls, but to provide abundant brakes, drags, and carriages, to take care that the owners of castles and baronial residences throw them open (with lunch provided) to the ardent student of British antiquities, to see that all the old ladies have somebody to talk to, and all the young ones somebody to flirt with, and generally to superintend the morals, happiness, and personal comfort of some fifty a.s.sorted scientific enthusiasts. The secretary who diverges from these his proper and elevated functions into trivial and puerile disquisitions upon the antiquity of man (when he ought rather to be admiring the juvenility of woman), or the precise date of the Anglo-Saxon conquest (when he should by rights be concentrating the whole force of his ma.s.sive intellect upon the arduous task of arranging for dinner), proves himself at once unworthy of his high position, and should forthwith be deposed from the secretariat by public acclamation.

Having once entrapped your perfect secretary, you set him busily to work beforehand to make all the arrangements for your expected excursion, the archaeologists generally cordially recognising the important principle that he pays all the expenses he incurs out of his own pocket, and drives splendid bargains on their account with hotel-keepers, coachmen, railway companies, and others to feed, lodge, supply, and convey them at fabulously low prices throughout the whole expedition. You also understand that the secretary will call upon everybody in the neighbourhood you propose to visit, induce the rectors to throw open their churches, square the housekeepers of absentee dukes, and beard the owners of Elizabethan mansions in their own dens. These little preliminaries being amicably settled, you get together your archaeologists and set out upon your intended tour.

An archaeologist, it should be further premised, has no necessary personal connection with archaeology in any way. He (or she) is a human being, of a.s.sorted origin, age, and s.e.x, known as an archaeologist then and there on no other ground than the possession of a ticket (price half-a-guinea) for that particular archaeological meeting. Who would not be a man (or woman) of science on such easy and unexacting terms? Most archaeologists within my own private experience, indeed, are ladies of various ages, many of them elderly, but many more young and pretty, whose views about the styles of English architecture or the exact distinction between Durotriges and d.a.m.nonians are of the vaguest and most shadowy possible description. You all drive in brakes together to the various points of interest in the surrounding country. When you arrive at a point of interest, somebody or other with a bad cold in his head reads a dull paper on its origin and nature, in which there is fortunately no subsequent examination. If you are burning to learn all about it, you put your hand up to your ear, and a.s.sume an att.i.tude of profound attention. If you are not burning with the desire for information, you stroll off casually about the grounds and gardens with the prettiest and pleasantest among the archaeological sisters, whose acquaintance you have made on the way thither. Sometimes it rains, and then you obtain an admirable chance of offering your neighbour the protection afforded by your brand-new silk umbrella. By-and-by the dull paper gets finished, and somebody who lives in an adjoining house volunteers to provide you with luncheon. Then you adjourn to the parish church, where an old gentleman of feeble eyesight reads a long and tedious account of all the persons whose monuments are or are not to be found upon the walls of that poky little building. n.o.body listens to him; but everybody carries away a vague impression that some one or other, temp. Henry the Second, married Adeliza, daughter and heiress of Sir Ralph de Thingumbob, and had issue thirteen stalwart sons and twenty-seven beautiful daughters, each founders of a n.o.ble family with a correspondingly varied pedigree. Finally, you take tea and ices upon somebody's lawn, by special invitation, and drive home, not without much laughter, in the cool of the evening to an excellent table d'hote dinner at the marvellously cheap hotel, presided over by the ever-smiling and urbane secretary. That is what we mean nowadays by being a member of an archaeological a.s.sociation.

It was on just such a pleasant excursion that we all went to Ogbury Barrows. I was overflowing, myself, with bottled-up information on the subject of those two prehistoric tumuli; for Ogbury Barrows have been the hobby of my lifetime; but I didn't read a paper upon their origin and meaning, first, because the secretary very happily forgot to ask me, and secondly, because I was much better employed in psychological research into the habits and manners of an extremely pretty pink-and-white archaeologist who stood beside me. Instead, therefore, of boring her and my other companions with all my acc.u.mulated store of information about Ogbury Barrows, I locked it up securely in my own bosom, with the fell design of finally venting it all at once in one vast flood upon the present article.

Ogbury Barrows, I would have said (had it not been for the praiseworthy negligence of our esteemed secretary), stand upon the very verge of a great chalk-down, overlooking a broad and fertile belt of valley, whose slopes are terraced in the quaintest fas.h.i.+on with long parallel lines of obviously human and industrial origin. The terracing must have been done a very long time ago indeed, for it is a device for collecting enough soil on a chalky hillside to grow corn in. Now, n.o.body ever tried to grow corn on open chalk-downs in any civilised period of history until the present century, because the downs are so much more naturally adapted for sheep-walks that the attempt to turn them into waving cornfields would never occur to anybody on earth except a barbarian or an advanced agriculturist. But when Ogbury Downs were originally terraced, I don't doubt that the primitive system of universal tribal warfare still existed everywhere in Britain. This system is aptly summed up in the familiar modern Black Country formula, 'Yon's a stranger. 'Eave 'arf a brick at him.' Each tribe was then perpetually at war with every other tribe on either side of it: a simple plan which rendered foreign tariffs quite unnecessary, and most effectually protected home industries. The consequence was, each district had to produce for its own tribe all the necessaries of life, however ill-adapted by nature for their due production: because traffic and barter did not yet exist, and the only form ever a.s.sumed by import trade was that of raiding on your neighbours' territories, and bringing back with you whatever you could lay hands on. So the people of the chalky Ogbury valley had perforce to grow corn for themselves, whether nature would or nature wouldn't; and, in order to grow it under such very unfavourable circ.u.mstances of soil and climate, they terraced off the entire hillside, by catching the silt as it washed slowly down, and keeping it in place by artificial barriers.

On the top of the down, overlooking this curious vale of prehistoric terraces, rise the twin heights of Ogbury Barrows, familiar landmarks to all the country side around for many miles. One of them is a tall, circular mound or tumulus surrounded by a deep and well-marked trench: the other, which stands a little on one side, is long and narrow, shaped exactly like a modern grave, but of comparatively gigantic and colossal proportions. Even the little children of Ogbury village have noticed its close resemblance of shape and outline to the gra.s.sy hillocks in their own churchyard, and whisper to one another when they play upon its summit that a great giant in golden armour lies buried in a stone vault underneath. But if only they knew the real truth, they would say instead that that big, ungainly, overgrown grave covers the remains of a short, squat, dwarfish chieftain, akin in shape and feature to the Lapps and Finns, and about as much unlike a giant as human nature could easily manage. It maybe regarded as a general truth of history that the greatest men don't by any means always get the biggest monument.

The archaeologists in becoming prints who went with us to the top of Ogbury Barrows sagaciously surmised (with demonstrative parasol) that 'these mounds must have been made a very long time ago, indeed.' So in fact they were: but though they stand now so close together, and look so much like sisters and contemporaries, one is ages older than the other, and was already green and gra.s.s-grown with immemorial antiquity when the fresh earth of its neighbour tumulus was first thrown up by its side, above the buried urn of some long-forgotten Celtic warrior. Let us begin by considering the oldest first, and then pa.s.s on to its younger sister.

Ogbury Long Barrow is a very ancient monument indeed. Not, to be sure, one quarter so ancient as the days of the extremely old master who carved the mammoth on the fragments of his own tusk in the caves of the Dordogne, and concerning whom I have indited a discourse in an earlier portion of this volume: compared with that very antique personage, our long barrow on Ogbury hill-top may in fact be looked upon as almost modern. Still, when one isn't talking in geological language, ten or twenty thousand years may be fairly considered a very long time as time goes: and I have little doubt that from ten to twenty thousand years have pa.s.sed since the short, squat chieftain aforesaid was first committed to his final resting-place in Ogbury Long Barrow. Two years since, we local archaeologists-not in becoming prints this time-opened the barrow to see what was inside it. We found, as we expected, the 'stone vault' of the popular tradition, proving conclusively that some faint memory of the original interment had clung for all those long years around the gra.s.sy pile of that ancient tumulus. Its centre, in fact, was occupied by a sepulchral chamber built of big Sa.r.s.en stones from the surrounding hillsides; and in the midst of the house of death thus rudely constructed lay the mouldering skeleton of its original possessor-an old prehistoric Mongoloid chieftain. When I stood for the first moment within that primaeval palace of the dead, never before entered by living man for a hundred centuries, I felt, I must own, something like a burglar, something like a body-s.n.a.t.c.her, something like a resurrection man, but most of all like a happy archaeologist.

The big stone hut in which we found ourselves was, in fact, a buried cromlech, covered all over (until we opened it) by the earth of the barrow. Almost every cromlech, wherever found, was once, I believe, the central chamber of just such a long barrow: but in some instances wind and rain have beaten down and washed away the surrounding earth (and then we call it a 'Druidical monument'), while in others the mound still encloses its original deposit (and then we call it merely a prehistoric tumulus). As a matter of fact, even the Druids themselves are quite modern and common-place personages compared with the short, squat chieftains of the long barrows. For all the indications we found in the long barrow at Ogbury (as in many others we had opened elsewhere) led us at once to the strange conclusion that our new acquaintance, the skeleton, had once been a living cannibal king of the newer stone-age in Britain.

The only weapons or implements we could discover in the barrow were two neatly chipped flint arrowheads, and a very delicate ground greenstone hatchet, or tomahawk. These were the weapons of the dead chief, laid beside him in the stone chamber where we found his skeleton, for his future use in his underground existence. A piece or two of rude hand-made pottery, no doubt containing food and drink for the ghost, had also been placed close to his side: but they had mouldered away with time and damp, till it was quite impossible to recover more than a few broken and shapeless fragments. There was no trace of metal in any way: whereas if the tribesmen of our friend the skeleton had known at all the art of smelting, we may be sure some bronze axe or spearhead would have taken the place of the flint arrows and the greenstone tomahawk: for savages always bury a man's best property together with his corpse, while civilised men take care to preserve it with pious care in their own possession, and to fight over it strenuously in the court of probate.

The chief's own skeleton lay, or rather squatted, in the most undignified att.i.tude, in the central chamber. His people when they put him there evidently considered that he was to sit at his ease, as he had been accustomed to do in his lifetime, in the ordinary savage squatting position, with his knees tucked up till they reached his chin, and his body resting entirely on the heels and haunches. The skeleton was entire: but just outside and above the stone vault we came upon a number of other bones, which told another and very different story. Some of them were the bones of the old prehistoric short-horned ox: others belonged to wild boars, red deer, and sundry similar animals, for the most part skulls and feet only, the relics of the savage funeral feast. It was clear that as soon as the builders of the barrow had erected the stone chamber of their dead chieftain, and placed within it his honoured remains, they had held a great banquet on the spot, and, after killing oxen and chasing red deer, had eaten all the eatable portions, and thrown the skulls, horns, and hoofs on top of the tomb, as offerings to the spirit of their departed master. But among these relics of the funeral baked meats there were some that specially attracted our attention-a number of broken human skulls, mingled indiscriminately with the horns of deer and the bones of oxen. It was impossible to look at them for a single moment, and not to recognise that we had here the veritable remains of a cannibal feast, a hundred centuries ago, on Ogbury hill-top.

Each skull was split or fractured, not clean cut, as with a sword or bullet, but hacked and hewn with some blunt implement, presumably either a club or a stone tomahawk. The skull of the great chief inside was entire and his skeleton unmutilated: but we could see at a glance that the remains we found huddled together on the top were those of slaves or prisoners of war, sacrificed beside the dead chieftain's tomb, and eaten with the other products of the chase by his surviving tribesmen. In an inner chamber behind the chieftain's own hut we came upon yet a stranger relic of primitive barbarism. Two complete human skeletons squatted there in the same curious att.i.tude as their lord's, as if in attendance upon him in a neighbouring ante-chamber. They were the skeletons of women-so our professional bone-scanner immediately told us-and each of their skulls had been carefully cleft right down the middle by a single blow from a sharp stone hatchet. But they were not the victims intended for the piece de resistance at the funeral banquet. They were clearly the two wives of the deceased chieftain, killed on his tomb by his son and successor, in order to accompany their lord and master in his new life underground as they had hitherto done in his rude wooden palace on the surface of the middle earth.

We covered up the reopened sepulchre of the old cannibal savage king (after abstracting for our local museum the arrowheads and tomahawk, as well as the skull of the very ancient Briton himself), and when our archaeological society, ably led by the esteemed secretary, stood two years later on the desecrated tomb, the gra.s.s had grown again as green as ever, and not a sign remained of the sacrilegious act in which one of the party then a.s.sembled there had been a prime actor. Looking down from the summit of the long barrow on that bright summer morning, over the gay group of picnicking archaeologists, it was a curious contrast to reinstate in fancy the scene at that first installation of the Ogbury monument. In my mind's eye I saw once more the howling band of naked, yellow-faced and yellow-limbed savages surge up the terraced slopes of Ogbury Down; I saw them bear aloft, with beating of b.r.e.a.s.t.s and loud gesticulations, the bent corpse of their dead chieftain; I saw the terrified and fainting wives haled along by thongs of raw oxhide, and the weeping prisoners driven pa.s.sively like sheep to the slaughter; I saw the fearful orgy of ma.s.sacre and rapine around the open tumulus, the wild priest shattering with his gleaming tomahawk the skulls of his victims, the fire of gorse and low brushwood prepared to roast them, the heads and feet flung carelessly on top of the yet uncovered stone chamber, the awful dance of blood-stained cannibals around the mangled remains of men and oxen, and finally the long task of heaping up above the stone hut of the dead king the earthen mound that was never again to be opened to the light of day till, ten thousand years later, we modern Britons invaded with our prying, sacrilegious mattock the sacred privacy of that cannibal ghost. All this pa.s.sed like a vision before my mind's eye; but I didn't mention anything of it at that particular moment to my fellow-archaeologists, because I saw they were all much more interested in the pigeon-pie and the funny story about an exalted personage and a distinguished actress with which the model secretary was just then duly entertaining them.

Five thousand years or so slowly wore away, from the date of the erection of the long barrow, and a new race had come to occupy the soil of England, and had driven away or reduced to slavery the short, squat, yellow-skinned cannibals of the earlier epoch. They were a pastoral and agricultural people, these new comers, acquainted with the use and abuse of bronze, and far more civilised in every way than their darker predecessors. No trace remains behind to tell us now by what fierce onslaught the Celtic invaders-for the bronze-age folk were presumably Celts-swept through the little Ogbury valley, and brained the men of the older race, while they made slaves of the younger women and serviceable children. Nothing now stands to tell us anything of the long years of Celtic domination, except the round barrow on the bare down, just as green and as gra.s.s-grown nowadays as its far earlier and more primitive neighbour.

We opened the Ogbury round barrow at the same time as the other, and found in it, as we expected, no bones or skeleton of any sort, broken or otherwise, but simply a large cinerary urn. The urn was formed of coa.r.s.e hand-made earthenware, very brittle by long burial in the earth, but not by any means so old or porous as the fragments we had discovered in the long barrow. A pretty pattern ran round its edge-a pattern in the simplest and most primitive style of ornamentation; for it consisted merely of the print of the potter's thumb-nail, firmly pressed into the moist clay before baking. Beside the urn lay a second specimen of early pottery, one of those curious perforated jars which antiquaries call by the very question-begging name of incense-cups; and within it we discovered the most precious part of all our 'find,' a beautiful wedge-shaped bronze hatchet, and three thin gold beads. Having no consideration for the feelings of the ashes, we promptly appropriated both hatchet and beads, and took the urn and cup as a peace-offering to the lord of the manor for our desecration of a tomb (with his full consent) on the land of his fathers.

Why did these bronze-age people burn instead of burying their dead? Why did they antic.i.p.ate the latest fas.h.i.+onable mode of disposal of corpses, and go in for cremation with such thorough conviction? They couldn't have been influenced by those rather unpleasant sanitary considerations which so profoundly agitated the mind of 'Graveyard Walker.' Sanitation was still in a very rudimentary state in the year five thousand B.C.; and the ingenious Celt, who is still given to 'waking' his neighbours, when they die of small-pox, with a sublime indifference to the chances of infection, must have had some other and more powerful reason for adopting the comparatively unnatural system of cremation in preference to that of simple burial. The change, I believe, was due to a further development of religious ideas on the part of the Celtic tribesmen above that of the primitive stone-age cannibals.

When men began to bury their dead, they did so in the firm belief in another life, which life was regarded as the exact counterpart of this present one. The unsophisticated savage, holding that in that equal sky his faithful dog would bear him company, naturally enough had the dog in question killed and buried with him, in order that it might follow him to the happy hunting-grounds. Clearly, you can't hunt without your arrows and your tomahawk; so the flint weapons and the trusty bow accompanied their owner in his new dwelling-place. The wooden haft, the deer-sinew bow-string, the perishable articles of food and drink have long since decayed within the damp tumulus: but the harder stone and earthenware articles have survived till now, to tell the story of that crude and simple early faith. Very crude and illogical indeed it was, however, for it is quite clear that the actual body of the dead man was thought of as persisting to live a sort of underground life within the barrow. A stone hut was constructed for its use; real weapons and implements were left by its side; and slaves and wives were ruthlessly ma.s.sacred, as still in Ashantee, in order that their bodies might accompany the corpse of the buried master in his subterranean dwelling. In all this we have clear evidence of a very inconsistent, savage, materialistic belief, not indeed in the immortality of the soul, but in the continued underground life of the dead body.

With the progress of time, however, men's ideas upon these subjects began to grow more definite and more consistent. Instead of the corpse, we get the ghost; instead of the material underground world, we get the idealised and sublimated conception of a shadowy Hades, a world of shades, a realm of incorporeal, disembodied spirits. With the growth of the idea in this ghostly nether world, there arises naturally the habit of burning the dead in order fully to free the liberated spirit from the earthly chains that clog and bind it. It is, indeed, a very noticeable fact that wherever this belief in a world of shades is implicitly accepted, there cremation follows as a matter of course; while wherever (among savage or barbaric races) burial is practised, there a more materialistic creed of bodily survival necessarily accompanies it. To carry out this theory to its full extent, not only must the body itself be burnt, but also all its belongings with it. Ghosts are clothed in ghostly clothing; and the question has often been asked of modern spiritualists by materialistic scoffers, 'Where do the ghosts get their coats and dresses?' The true believer in cremation and the shadowy world has no difficulty at all in answering that crucial inquiry; he would say at once, 'They are the ghosts of the clothes that were burnt with the body.' In the gossiping story of Periander, as veraciously retailed for us by that dear old grandmotherly scandalmonger, Herodotus, the shade of Melissa refuses to communicate with her late husband, by medium or otherwise, on the ground that she found herself naked and s.h.i.+vering with cold, because the garments buried with her had not been burnt, and therefore were of no use to her in the world of shades. So Periander, to put a stop to this sad state of spiritual dest.i.tution, requisitioned all the best dresses of the Corinthian ladies, burnt them bodily in a great trench, and received an immediate answer from the gratified shade, who was thenceforth enabled to walk about in the princ.i.p.al promenades of Hades among the best-dressed ghosts of that populous quarter.

The belief which thus survived among the civilised Greeks of the age of the Despots is shared still by Fijis and Karens, and was derived by all in common from early ancestors of like faith with the founders of Ogbury round barrow. The weapons were broken and the clothes burnt, to liberate their ghosts into the world of spirits, just as now, in Fiji, knives and axes have their spiritual counterparts, which can only be released when the material shape is destroyed or purified by the action of fire. Everything, in such a state, is supposed to possess a soul of its own; and the fire is the chosen mode for setting the soul free from all clogging earthly impurities. So till yesterday, in the rite of suttee, the Hindoo widow immolated herself upon her husband's pyre, in order that her spirit might follow him unhampered to the world of ghosts whither he was bound. Thus the twin barrows on Ogbury hillside bridge over for us two vast epochs of human culture, both now so remote as to merge together mentally to the casual eyes of modern observers, but yet in reality marking in their very shape and disposition an immense, long, and slow advance of human reason. For just as the long barrow answers in form to the buried human corpse and the chambered hut that surrounds and encloses it, so does the round barrow answer in form to the urn containing the calcined ashes of the cremated barbarian. And is it not a suggestive fact that when we turn to the little graveyard by the church below we find the Christian belief in the resurrection of the body, as opposed to the pagan belief in the immortality of the soul, once more bringing us back to the small oblong mound which is after all but the dwarfed and humbler modern representative of the long barrow? So deep is the connection between that familiar shape and the practice of inhumation that the dwarf long barrow seems everywhere to have come into use again throughout all Europe, after whole centuries of continued cremation, as the natural concomitant and necessary mark of Christian burial.

This is what I would have said, if I had been asked, at Ogbury Barrows. But I wasn't asked; so I devoted myself instead to psychological research, and said nothing.

FISH OUT OF WATER

Strolling one day in what is euphemistically termed, in equatorial lat.i.tudes, 'the cool of the evening,' along a tangled tropical American field-path, through a low region of lagoons and watercourses, my attention happened to be momentarily attracted from the monotonous pursuit of the nimble mosquito by a small animal scuttling along irregularly before me, as if in a great hurry to get out of my way before I could turn him into an excellent specimen. At first sight I took the little hopper, in the grey dusk, for one of the common, small green lizards, and wasn't much disposed to pay it any distinguished share either of personal or scientific attention. But as I walked on a little further through the dense underbrush, more and more of these shuffling and scurrying little creatures kept crossing the path, hastily, all in one direction, and all, as it were, in a formed body or marching phalanx. Looking closer, to my great surprise, I found they were actually fish out of water, going on a walking tour, for change of air, to a new residence-genuine fish, a couple of inches long each, not eel-shaped or serpentine in outline, but closely resembling a red mullet in miniature, though much more beautifully and delicately coloured, and with fins and tails of the most orthodox spiny and p.r.i.c.kly description. They were travelling across country in a bee-line, thousands of them together, not at all like the helpless fish out of water of popular imagination, but as unconcernedly and naturally as if they had been accustomed to the overland route for their whole lifetimes, and were walking now on the king's highway without let or hindrance.

I took one up in my hand and examined it more carefully; though the catching it wasn't by any means so easy as it sounds on paper, for these perambulatory fish are thoroughly inured to the dangers and difficulties of dry land, and can get out of your way when you try to capture them with a rapidity and dexterity which are truly surprising. The little creatures are very pretty, well-formed catfish, with bright, intelligent eyes, and a body armed all over, like the armadillo's, with a continuous coat of hard and h.o.r.n.y mail. This coat is not formed of scales, as in most fish, but of toughened skin, as in crocodiles and alligators, arranged in two overlapping rows of imbricated s.h.i.+elds, exactly like the round tiles so common on the roofs of Italian cottages. The fish walks, or rather shambles along ungracefully, by the shuffling movement of a pair of stiff spines placed close behind his head, aided by the steering action of his tail, and a constant snake-like wriggling motion of his entire body. Leg spines of somewhat the same sort are found in the common English gurnard, and in this age of Aquariums and Fisheries Exhibitions, most adult persons above the age of twenty-one years must have observed the gurnards themselves crawling along suspiciously by their aid at the bottom of a tank at the Crystal Palace or the polyonymous South Kensington building. But while the European gurnard only uses his subst.i.tutes for legs on the bed of the ocean, my itinerant tropical acquaintance (his name, I regret to say, is Callichthys) uses them boldly for terrestrial locomotion across the dry lowlands of his native country. And while the gurnard has no less than six of these pro-legs, the American land fish has only a single pair with which to accomplish his arduous journeys. If this be considered as a point of inferiority in the armour-plated American species, we must remember that while beetles and gra.s.shoppers have as many as six legs apiece, man, the head and crown of things, is content to scramble through life ungracefully with no more than two.

There are a great many tropical American pond-fish which share these adventurous gipsy habits of the pretty little Callichthys. Though they belong to two distinct groups, otherwise unconnected, the circ.u.mstances of the country they inhabit have induced in both families this queer fas.h.i.+on of waddling out courageously on dry land, and going on voyages of exploration in search of fresh ponds and shallows new, somewhere in the neighbourhood of their late residence. One kind in particular, the Brazilian Doras, takes land journeys of such surprising length, that he often spends several nights on the way, and the Indians who meet the wandering bands during their migrations fill several baskets full of the prey thus dropped upon them, as it were, from the kindly clouds.

Both Doras and Callichthys, too, are well provided with means of defence against the enemies they may chance to meet during their terrestrial excursions; for in both kinds there are the same bony s.h.i.+elds along the sides, securing the little travellers, as far as possible, from attack on the part of hungry piscivorous animals. Doras further utilises its powers of living out of water by going ash.o.r.e to fetch dry leaves, with which it builds itself a regular nest, like a bird's, at the beginning of the rainy season. In this nest the affectionate parents carefully cover up their eggs, the hope of the race, and watch over them with the utmost attention. Many other fish build nests in the water, of materials naturally found at the bottom; but Doras, I believe, is
