Journal of an Overland Expedition in Australia Part 10

April 19.--Continuing our journey in a north-west direction, we pa.s.sed over some very rocky hills, composed of indurated clay, and thin strata of sandstone, and pudding-stone. By moving along the foot of a range of high hills, we avoided all those deep gullies which intersected the banks of the river, and travelled with ease through a flat, well gra.s.sed Ironbark forest. The hills were covered, as usual, with stunted silver-leaved Ironbark. A large creek came from the range, and entered the river. A good section on its right bank exposed to view the strata of indurated clay and sandstone; and I was induced to believe that coal might be found below them. As we were pa.s.sing over the flat between the creck and the river, we saw a native busily occupied in burning the gra.s.s, and eagerly watching its progress: the operation attracted several crows, ready to seize the insects and lizards which might be driven from their hiding places by the fire. Mr. Calvert, Brown, and Charley, rode nearly up to the man before he was aware of their approach; when he took to his heels, and fled in the greatest consternation.

Upon reaching the river, at about eight miles from our last camp, we found that it was joined by another river of almost the same size as the Burdekin: it had a stream, and came from the northward, whilst the course of the Burdekin at this place was from the west to east. From the junction a long range trended to the north-east, and moderate ranges bounded the valley of the river from the northward; another range extended along the left side of the Burdekin above the junction; and basaltic ridges, which had broken through the sandstone, approached on its right. The cucurbitaceous plant with palmate leaves, bore a fruit of the size of a large orange, of a fine scarlet colour when ripe; its rind is exceedingly bitter, but the seeds are eaten by birds. Mr. Phillips found a flesh-coloured drupaceous oblong fruit, about half an inch long, with a very glutinous pericarp, containing a slightly compressed rough stone: in taste it resembled the fruit of Loranthus, and the birds, particularly the coekatoos, appeared very fond of it. We all ate a great quant.i.ty of them, without the slightest injury. It grew on a small tree, and had a persistent calyx.

April 20.--We travelled in a N. 80 degrees W. course to lat.i.tude 19 degrees 9 minutes 88 seconds. Rocky ranges frequently approached the river, and deep and intricate gullies descended from them to the latter.

Our progress was consequently very difficult, and we were compelled to ascend a very high hill to avoid its slopes towards the river, which were too steep for us to cross. As a recompense, however, for the difficulty of the ascent, I had the pleasure of finding some very interesting plants on its summit; particularly a small Acacia with verticillate leaves, which Dr. Binoe, the surgeon of H. M. S. Beagle, had found on the north-west coast; and two other Acacias equally new to me, and which were afterwards found to extend to the heads of the South Alligator River.

From this hill we had a magnificent view of the country before us: it was enclosed on all sides by high mountain ranges, of which one in particular overtopped the rest. Porphyry was observed on several spots; indurated clay frequently; and, on the top of the hill below which we encamped, I found quartz porphyry, and at the foot a psammite? which I had met several times a.s.sociated with talc-schiste.

April 21.--We continued our journey in a S. 50 degrees W. course to lat.i.tude 19 degrees 13 minutes. The country became still more mountainous; we pa.s.sed, notwithstanding, many large well gra.s.sed flats, on which the timber grew to a greater size than we had observed it at the lower part of the river. The poplar-gum was very frequent in the hollow, and low stiff flats extended parallel to the river. The prevailing rock was talc-schiste, alternating with layers of psammite. On the hills and in the creeks, I frequently observed conglomerate, with many pieces of quartz.

The drooping Hakea of Kent's Lagoon (Hakea lorea, R. Br.; Grevillea lorea, R. Br. Prodr. Nov. Holl. I. p. 380) was in blossom; and on the rocky slopes I found a new species of Hakea, having linear lanceolate leaves with axillary fascicules of small brownish flowers: it was an arborescent shrub, from three to six feet high; and is nearly allied to H. arborescens (R. Br. Prodr. p. 386).

A high imposing range was visible to the northward.

April 22.--We travelled about nine miles west, making our lat.i.tude 19 degrees 12 minutes. Ranges ran parallel to the river at different distances: we left a very fine one to the south-west and south, from which the large creek we pa.s.sed about two miles from our last camp, probably descends. Three miles farther, a river as large or even larger than the Burdekin, joins the latter from the westward and south-west-- the Burdekin coming down from the north-west. I was doubtful which of the two rivers I ought to follow; but finding, after a close examination, that the north-west branch was running, whilst the south-west one contained only large, long, but unconnected reaches of water, I determined upon following the north-west branch. I called the south-west branch the "Clarke," in compliment to the Rev. W. B. Clarke of Paramatta, who has been, and is still, most arduously labouring to elucidate the meteorology and the geology of this part of the world. About three miles above the junction, a creek of considerable size joined the Burdekin from the northward. Wherever the ridges approached the banks of the river, gullies which were scrubby at their heads, became numerous. After having encamped, I rode over to the "Clarke," to examine the intervening country. The flat along the Burdekin was about two miles and a half broad, and was skirted by silver-leaved Ironbark ridges. In approaching the Clarke, we came to a low basaltic range, which bounded its fine broad openly timbered valley to the northward. The bed of the river was formed by talc-schiste, in strata, the strike of which was from north by west to south by east, standing almost perpendicular, with a slight dip to the eastward. The stream was perpendicular on the line of striking. The pebbles in its bed were mostly basaltic, baked sandstone, conglomerate, quartz, sienite, and porphyry. I had observed the valley of this river from a high hill near our last camp, and had distinguished many headlands, which I now think were the bluff terminations of lateral basaltic ranges. The valley was bounded on its southern side by a long low range.

The blue mountain parrot was very frequent near our camp.

I have mentioned a small round eatable tuber, which I found in the basket of a native gin on the 2nd January. I here found it to be the large end of the tap root of a Potamogeton, or a plant nearly allied to that genus; I found it with another interesting water-plant, with foliated spikes of blue flowers, in a small water-hole near our last camp.

April 23.--We travelled about north-west to lat.i.tude 19 degrees 4 minutes 41 seconds, over a succession of fine flats; one or two of which were almost exclusively timbered with poplar-gum, which always indicated a sound stiff soil. These flats were separated by shallow gullies, and some Casuarina creeks, which come probably from the dividing ridges of the two rivers. Ridges and ranges were seen on both sides, at different distances. The Casuarina became more frequent along the banks of the river. It was rather remarkable that the Moreton Bay ash, which is so abundant along the Burdekin, was altogether wanting at the Clarke.

Several lagoons were observed at the foot of the ridges; and near them we saw two flocks of the harlequin pigeon (Peristera histrionica).

Talc-schiste cropped out in one of the deep creeks. Whilst travelling on the Burdekin, with the exception of some ducks and a few kangaroos, we had seen but very little game; but yesterday, when riding to the Clarke, two flocks of kangaroos pa.s.sed me: a proof that the country is not so dest.i.tute of game as I had thought. The waters are inhabited by four varieties of fish; one was probably a Gristes, about eight inches long, and from one and a half to two inches broad, of a lanceolate shape, with bright yellow spots all over the body; a second smaller than Gristes, with dark stripes; a third about a foot long, and three inches broad, belonging to the Percidae; and a fourth, a small fish, which seemed to be allied to the Cyprinidae. Larger fish exist, probably, in the deep rocky basins of water which we occasionally pa.s.sed; but we never succeeded in catching any; nor did we hear any of the splas.h.i.+ng, which was so incessant during the night at the Mackenzie. The sh.e.l.l and bones of the turtle indicated its presence in the shady ponds fringed by drooping tea trees. Large holes in the banks immediately above the water, were probably inhabited by water rats or lizards. A common carpet snake was killed. Whenever we pa.s.sed through open Vitex scrub, with its stiff loamy soil, we were sure of meeting a great number of the conical constructions of the white ant: they were from one to three feet high, very narrow, and tapering to a sharp point.

April 24.--To-day we travelled along the river over an open country, intersected by some gullies; the course of the river was, for about four miles, from north to south, and, at that distance from our camp, was joined by a river coming from the northward, which I now take the liberty of naming the "Perry," after Captain Perry, Deputy Surveyor-General, who has most kindly mapped my route from the rough plans sketched during the journey. The Burdekin here comes from the westward, and made a large bend round several mountains, composed of quartz porphyry, with a sub-crystalline felspathic paste. The lat.i.tude was 19 degrees 1 minutes (Unclear:)18.

April 25.--We travelled almost due west, about nine miles along the river, our lat.i.tude being 19 degrees 1 minutes 3 seconds. Our route lay through a fine well gra.s.sed country; the gra.s.s being very dense: at a distance from the river, I observed box flats, and poplar-gum flats; the latter are probably swampy during the rainy season. A good sized creek joined the Burdekin; a range of high hills extended along its left side, and its right became equally hilly as we approached our camping place.

After establis.h.i.+ng our camp, and making the necessary preparations, we killed one of our little steers, and found it in excellent condition. The graziers will judge by this simple fact, how well the country is adapted for pastoral pursuits; particularly when it is remembered that we were continually on the march, and had frequently to pa.s.s over very rocky ranges, which made our cattle footsore; and that the season was not the most favourable for the gra.s.s, which, although plentiful, was very dry.

The steer gave us 120 lbs. of dried beef.

In this place I observed and calculated three sets of lunar observations; one gave longitude 144 degrees 4 minutes, and the other longitude 144 degrees 14 minutes. As usual, we greased our harness, although not without considerable discussion, as to whether it would not be more advisable to eat the fat than to apply it to the leather; we also repaired our packs and pack-saddles, and put every thing in travelling order.

On the 29th April we started from our killing camp, and travelled about seven miles N. 70 degrees W.; making our lat.i.tude 18 degrees 59 minutes.

The ranges now approached the banks of the river, and r.e.t.a.r.ded our progress very much.

April 30.--In consequence of Charley's statement, that the banks of the river in advance were so steep and rocky that it would be impossible for us to pa.s.s, I left the river side, and crossed over the ranges, and had a very heavy stage for my bullocks; which I regretted the more, as Mr.

Calvert and Brown, who returned to our last camp for a sword, had found the route by the river quite practicable. The ranges were composed of a Psammite, which was frequently baked, probably by neighbouring out-bursts of igneous rock. Several familiar forms of plants were discovered; also a new Eucalyptus, with a glaucous suborbicular subcordate leaf, and the bark of the rusty gum: a stunted or middle-sized tree, which grew in great abundance on the ranges. We pa.s.sed a fine large but dry Casuarina creek, coming from the westward, with a broad sandy bed. A large tree, with dark green broad lanceolate stinging leaves, grew on its banks; it resembled the nettle tree, but belonged to neither of the two species growing in the bushes of the east coast.

Our last day's travelling had not advanced us more than five miles in a straight line, and we had not made any northing, our lat.i.tude being again 18 degrees 59 minutes; but we had left the mountains behind us, and had travelled, during the latter part of the stage, over well gra.s.sed, openly timbered flats. The ranges on the left side of the river extended several miles farther, but gradually sunk into a level country.

[Note 1: The following description of the fossiliferous limestone of the Burdekin, was communicated to me by the Rev. W. B. Clarke, F.G.S.

This rock consists of a semi-crystalline, greyish-brown marble, very like some varieties of Wenlock limestone.

The most conspicuous fossil is a coral, which appears to belong to the family of Cyathophyllidae. The genus is perhaps new; but this the want of specimens with which to compare it, does not allow me the means of verifying. It may, however, be cla.s.sed provisionally as Cyathophyllum, to which in many respects it bears a great resemblance; and although it is somewhat contrary to the present rules of cla.s.sification to a.s.sign a specific name from a person, yet, in order to do honour to my friend on account of his skill, diligence, and zeal as a naturalist, as well as a traveller, and as this is the first fossil coral brought away by the first explorer of the region in which its habitat is found, I venture to name it C. Leichhardti.

The description may be given as follows:

Cells concavely cylindrical, not dichotomous (thus distinguished from Caryophyllia), grouped but separate, laterally if at all proliferous.

Corallum beautifully stellular, formed by 30-35 slightly spirally-curving or regular radiating lamellae, which meet in a central point or overlap on a lat.i.tudinal axial line, and are divided by rectangular or outwardly convex and upwardly oblique dissepiments, which become, occasionally, indistinct or obsolete near the centre, thus not a.s.suming the usual characteristic of Cyathophyllum, but rather one of Strombodes.

Surface longitudinally striated, the cellular structure being hidden in calcareous spar; the striae formed by the coalescing lamellae, which, at the extremities, seem to be occasionally denticulated, owing to the matrix interrupting their pa.s.sage to the edge. This resembles what takes place in some Astraeidae.

The interior has more the features of Acervularia than Cyathophyllum; but there are patches of broken transverse septa in the rock which exhibit the features of the latter.

a.s.sociated with this is a branching coral, a fragment of which, in a small angle of one of the surfaces of the stone, exhibits the characters of Favosites. There are also traces of casts of Spirifers, one of which is near to S. Pisum of the Wenlock rocks. (Silur. Syst. pl. xiii. f. 9).

The description here given is deduced from the natural appearances under the lens, and not from artificial or regular sections. But the specimen admits of a partial subst.i.tute for this; for the surface is worn down and roughly polished, as is the case with all the exposed surfaces of ancient limestones in Australia; the result probably of the acidulous properties of rain water, or of the atmosphere, which, in a tropical climate, where violent showers alternate with great drought, is capable of producing various sensible changes in rocks in a long series of ages. Many rocks of limestone in New South Wales, even harder than the Burdekin marble, are actually grooved in short parallel furrows, over wide surfaces, and along their sides, by some similar agency.]

BROWN AND CHARLEY QUARREL--NIGHT WATCH--ROUTINE OF OUR DAILY LIFE, AND HABITS OF THE MEMBERS OF THE PARTY--MOUNT LANG--STREAMS OF LAVA--A HORSE BREAKS HIS LEG, IS KILLED AND EATEN--NATIVE TRIBE--MR. ROPER'S ACCIDENT--WHITSUNDAY--BIG ANT HILL CREEK--DEPRIVED OF WATER FOR FIFTY HOURS--FRIENDLY NATIVES--SEPARATION CREEK--THE LYND--PSYCHOLOGICAL EFFECTS OF A SOJOURN IN THE WILDERNESS--NATIVE CAMP--SALT EXHAUSTED.

May 1.--We travelled west by north, to lat.i.tude 18 degrees 55 minutes 41 seconds, over almost a dead flat, which was only interrupted by a fine Casuarina creek, with a broad sandy bed, coming from the south-south-west. The soil was stiff, and the forest in which the Box tree prevailed, was very open. A species of Acacia, with narrow blunt phyllodia, about an inch long, with spinous stipules; Hakea lorea, and the Grevillea mimosoides (R. Br.), with very long linear leaves, were frequent. Towards the end of the journey, slight ridges, composed of flint rock, rose on our left; and the country became more undulating. Mr.

Roper saw extensive ranges about fifteen miles distant; shortly before entering the camp, we pa.s.sed a singularly broken country, in which the waters rus.h.i.+ng down from a slightly inclined table land, had hollowed out large broad gullies in a sandy loam and iron ochre, which was full of quartz pebbles. The heavier ma.s.ses had resisted the action of the waters, and remained like little peaks and islands, when the softer materials around them had been washed away. We met with gra.s.s lately burnt, and some still burning, which indicated the presence of natives. It was generally very warm during the hours of travelling, between eight and twelve o'clock, but the bracing air of the nights and mornings strengthened us for the day's labour; the weather altogether was lovely, and it was a pleasure to travel along such a fine stream of water.

Easterly and north-easterly breezes still prevailed, though I expected that the direction of the winds would change as we pa.s.sed the centre of York Peninsula.

Our two black companions, who until now had been like brothers--entertaining each other by the relation of their adventures, to a late hour of the night; singing, chatting, laughing, and almost crying together; making common cause against me; Brown even following Charley into his banishment--quarrelled yesterday, about a mere trifle, so violently that it will be some time before they become friends again.

When Mr. Calvert and Brown returned yesterday to the camp, they remarked that they had not seen the waterfall, of which Charley had spoken whilst at our last camp; upon which Charley insinuated that they had not seen it, because they had galloped their horses past it. This accusation of galloping their horses irritated Brown, who was very fond and proud of his horse; and a serious quarrel of a rather ridiculous character ensued.

Keeping myself entirely neutral, I soon found that I derived the greatest advantage from their animosity to each other, as each tried to outdo the other in readiness to serve me. To-day, Charley, who was usually the last to rise in the morning, roused even me, and brought the horses before our breakfast was ready. Brown's fondness for spinning a yarn will soon, however, induce him to put an end to this feud with his companion and countryman. In the early part of our journey, one or other of our party kept a regular night-watch, as well to guard us from any night attack of the natives, as to look after our bullocks; but, latterly, this prudential measure, or rather its regularity, has been much neglected.

Mr. Roper's watch was handed from one to another in alphabetical rotation at given intervals, but no one thought of actually watching; it was, in fact, considered to be a mere matter of form. I did not check this, because there was nothing apparently to apprehend from the natives, who always evinced terror in meeting us; and all our communications with them have been accidental and never sought by them. On that point, therefore, I was not apprehensive; and, as to the bullocks, they were now accustomed to feed at large, and we seldom had any difficulty in recovering them in the morning. I shall here particularise the routine of one of our days, which will serve as an example of all the rest. I usually rise when I hear the merry laugh of the laughing-jacka.s.s (Dacelo gigantea), which, from its regularity, has not been unaptly named the settlers' clock; a loud cooee then roused my companions,--Brown to make tea, Mr. Calvert to season the stew with salt and marjoram, and myself and the others to wash, and to prepare our breakfast, which, for the party, consists of two pounds and a-half of meat, stewed over night; and to each a quart pot of tea. Mr. Calvert then gives to each his portion, and, by the time this important duty is performed, Charley generally arrives with the horses, which are then prepared for their day's duty. After breakfast, Charley goes with John Murphy to fetch the bullocks, which are generally brought in a little after seven o'clock a.m. The work of loading follows, but this requires very little time now, our stock being much reduced; and, at about a quarter to eight o'clock, we move on, and continue travelling four hours, and, if possible, select a spot for our camp. The Burdekin, which has befriended us so much by its direct course and constant stream, already for more than two degrees of lat.i.tude and two of longitude, has not always furnished us with the most convenient camps for procuring water. The banks generally formed steep slopes descending into a line of hollows parallel to the river, and thickly covered with a high stiff gra.s.s; and then another steep bank covered with a thicket of drooping tea-trees, rose at the water's edge; and, if the descent into the bed of the river was more easy, the stream frequently was at the opposite side, and we had to walk several hundred yards over a broad sheet of loose sand, which filled our moca.s.sins, when going to wash. At present, the river is narrower, and I have chosen my camp twice on its dry sandy bed, under the shade of Casuarinas and Melaleucas, the stream being there comparatively easy of access, and not ten yards off. Many unpleasant remarks had been made by my companions at my choice of camping places; but, although I suffered as much inconvenience as they did, I bore it cheerfully, feeling thankful to Providence for the pure stream of water with which we were supplied every night. I had naturally a great antipathy against comfort-hunting and gourmandizing, particularly on an expedition like ours; on which we started with the full expectation of suffering much privation, but which an Almighty Protector had not only allowed us to escape hitherto, but had even supplied us frequently with an abundance--in proof of which we all got stronger and improved in health, although the continued riding had rather weakened our legs. This antipathy I expressed, often perhaps too harshly, which caused discontent; but, on these occasions, my patience was sorely tried. I may, however, complete the picture of the day: as soon as the camp is pitched, and the horses and bullocks unloaded, we have all our alloted duties; to make the fire falls to my share; Brown's duty is to fetch water for tea; and Mr. Calvert weighs out a pound and a-half of flour for a fat cake, which is enjoyed more than any other meal; the large teapot being empty, Mr. Calvert weighs out two and a-half pounds of dry meat to be stewed for our late dinner; and, during the afternoon, every one follows his own pursuits, such as was.h.i.+ng and mending clothes, repairing saddles, pack-saddles, and packs; my occupation is to write my log, and lay down my route, or make an excursion in the vicinity of the camp to botanize, etc. or ride out reconnoitring. My companions also write down their remarks, and wander about gathering seeds, or looking for curious pebbles. Mr. Gilbert takes his gun to shoot birds. A loud cooee again unites us towards sunset round our table cloth; and, whilst enjoying our meals, the subject of the day's journey, the past, the present, and the future, by turns engage our attention, or furnish matter for conversation and remark, according to the respective humour of the parties. Many circ.u.mstances have conspired to make me strangely taciturn, and I am now scarcely pleased even with the chatting humour of my youngest companion, whose spirits, instead of flagging, have become more buoyant and lively than ever. I consider it, however, my invariable duty to give every information I can, whenever my companions inquire or show a desire to learn, and I am happy to find that they are desirous of making themselves familiar with the objects of nature by which they are surrounded, and of understanding their mutual relations. Mr. Roper is of a more silent disposition; Mr. Calvert likes to speak, and has a good stock of "small talk," with which he often enlivens our dinners; he is in that respect an excellent companion, being full of jokes and stories, which, though old and sometimes quaint, are always pure, and serve the more to exhilarate the party. Mr. Gilbert has travelled much, and consequently has a rich store of impressions de voyage: his conversation is generally very pleasing and instructive, in describing the character of countries he has seen, and the manners and customs of the people he has known. He is well informed in Australian Ornithology. As night approaches, we retire to our beds. The two Blackfellows and myself spread out each our own under the canopy of heaven, whilst Messrs. Roper, Calvert, Gilbert, Murphy, and Phillips, have their tents. Mr. Calvert entertains Roper with his conversation; John amuses Gilbert; Brown tunes up his corroborri songs, in which Charley, until their late quarrel, generally joined. Brown sings well, and his melodious plaintive voice lulls me to sleep, when otherwise I am not disposed. Mr. Phillips is rather singular in his habits; he erects his tent generally at a distance from the rest, under a shady tree, or in a green bower of shrubs, where he makes himself as comfortable as the place will allow, by spreading branches and gra.s.s under his couch, and covering his tent with them, to keep it shady and cool, and even planting lilies in blossom (Crinum) before his tent, to enjoy their sight during the short time of our stay. As the night advances, the Blackfellows' songs die away; the chatting tongue of Murphy ceases, after having lulled Mr. Gilbert to sleep; and at last even Mr.

Calvert is silent, as Roper's short answers became few and far between.

The neighing of the tethered horse, the distant tinkling of the bell, or the occasional cry of night birds, alone interrupt the silence of our camp. The fire, which was bright as long as the corroborri songster kept it stirred, gradually gets dull, and smoulders slowly under the large pot in which our meat is simmering; and the bright constellations of heaven pa.s.s unheeded over the heads of the dreaming wanderers of the wilderness, until the summons of the laughing jacka.s.s recalls them to the business of the coming day.

May 2.--We travelled in a N.W. direction to lat. 18 degrees 50 minutes 11 seconds; at first over the box flats, alternating with an undulating open country. About three miles before making our camp, we pa.s.sed several small plains at the foot of what appeared to be basaltic ridges, and came to the dry channel of a river, with reeds and occasional water-holes, and lined with fine flooded-gum trees and Casuarinas, but without the dropping tea trees and the Moreton Bay ash, the latter of which seemed to be the prerogative of the Burdekin. At its left side a basaltic ridge rose, covered with thick scrub, and at its base extended a small plain, with black soil strewed with quartz pebbles. The river came, as well as I could judge, from the W.N.W. Mr. Roper and Brown caught a kangaroo, but they had a dangerous ride after it, and the poor brute, when hard pressed, showed fight, and endeavoured to lay hold of Mr. Roper.

In one of the creeks I observed pegmat.i.te; pebbles of talc-schiste and of white quartz covered the bed of the river.

May 3.--We had to travel for a considerable distance in the bed of the river, for the hills approached close to its banks, and numerous deep gullies intercepted their slopes. When, however, the ridges receded, we pa.s.sed several fine sound flats. The forest was open everywhere, and the gra.s.s was good, though old. After travelling about five miles, we saw a hill to the north-east, and, when we came almost abreast of it, the river turned to the eastward, and a wild field of broken basaltic lava rendered it impossible for us to follow its banks. The black rough ma.s.ses of rock were covered with thick scrub, in which I observed numerous bottle trees with the plata.n.u.s leaf. Keeping to the westward of the scrub, I followed a creek which farther on divided in a chain of ponds, into which the waters of the field of basalt, as well as of the basaltic ridges to the westward of it, collected. These ridges were perfectly level at their summits, and were connected with a table land which extended far to the west. At their foot sienite, quartz rock, and leptinite, were observed.

After turning round the field of lava to the eastward, we entered into a large flat, with patches of narrow-leaved tea tree, with reedy swamps and fine flooded-gum trees, and made our camp at a strong running brook, without trees, but densely surrounded with reeds, ferns, and pothos. This stream formed the outlet of some fine lagoons, which extended along the steep slopes of the basaltic table land. I crossed the creek and its flat to the opposite hills. The flat was one level sheet or floor of basalt, here and there covered with a very shallow soil, but sometimes bare, though clothed with a fair supply of gra.s.s and with scattered flooded-gum trees. At the foot of the eastern hills, however, deep holes existed in a water-course, with black blocks of basalt heaped over each other, on which the fig tree with its dark green foliage formed a shady bower, most delightful during the heat of the day. The hills were composed of a lamellar granite, approaching the stratified appearance of gneiss, but the leaflets of mica, instead of forming continuous layers, were scattered. The east side of the narrow watercourse was of primitive rock, the west side basaltic. Having pa.s.sed over the hills, I made the river at their east side. Its banks were open for access as far as the primitive rock extended, but another field of lava commenced higher up, and rendered any progress with our cattle impossible.

A native low shrubby Mulberry was found in this scrub, the fruit of which was good to eat, but of very small size.

From the top of the hills I enjoyed a most beautiful view of the valley of the river, with its large lagoons covered with Nymphaeas and Damasoniums. On one of the lagoons, Charley shot a Parra gallinacea, a bird which Mr. Gilbert had observed only at Port Essington. A well beaten path of the natives showed that they were numerous in this part of the country: we saw many of their camping places during the stage; and the fires of their camps were numerous; we saw a party of them, but they were too frightened to allow us to approach. Our lat.i.tude was 18 degrees 44 minutes 48 seconds. Our course was about N.N.W.

May 4.--We ascended the basaltic ridges, and reaching the table land, found it perfectly level, openly timbered, well gra.s.sed, but occasionally stony, by which our poor foot-sore bullocks suffered severely. About five miles north-west by west from our camp, we discovered an extensive valley with large lagoons and lakes, and a most luxuriant vegetation, bounded by blue distant ranges, and forming the most picturesque landscape we had yet met with. A chain of lagoons connected by a reedy brook followed the outlines of the table land, along the foot of its steep slopes. We descended by a tolerably gentle slope into the valley, and encamped near the reedy brook, which must be the same as that on which, lower down, our last camp was formed. Water, gra.s.s, hills, mountains, plains, forest land; all the elements of a fine pasturing country, were here united.

During one of the last stages, we discovered a leguminous tree, with the dark fissured bark of the Ironbark, but with large bipinnate leaves, the leaflets oblong, an inch in length; the pods broad and thin, and two or three inches long: this tree is common all over the northern part of the continent, and was found growing abundantly around Victoria, the princ.i.p.al settlement of Port Essington.

Mr. Roper and Brown, upon an excursion after ducks, which were very numerous on the lagoons, met with Blackfellows, who were willing to accost Brown, but could not bear the sudden sight of a white face. In trying to cross the valley, my course was intercepted every way by deep reedy and sedgy lagoons, which rendered my progress impossible. I saw, however, that this valley was also floored with a sheet of lava hollowed out into numerous deep basins, in which the water collected and formed the lagoons.

May 5.--I went with Charley to reconnoitre the upper part of the reedy brook, with a view to find a pa.s.sage over the table land to the westward; at the same time I sent Mr. Roper and Brown to trace the river through the lagoons, and to examine whether there was any connection between them. I followed the base of the basaltic table land, along which the brook came down, and, after a two miles' ride on its banks, through oak trees, low fern trees, and several bush trees, found that it came down a valley deeply cut into the table land. The floor of the valley was of basaltic rock, and its steep slopes were covered with boulders of the same formation. The water ran in two distinct beds through the fissures, hollows, and caves of the rock. As our horses could not travel over the sharp edges of the rock without injuring their feet, we ascended the table land, and rode to the northward about four miles, and then came on plains, in which we distinguished a meandering band of green verdure, which proved to be the same brook we had left, or one of its head waters.
