The Exploring Expedition to the Rocky Mountains, Oregon and California Part 27

I have the honor to be your most ob't ser't, R. B. MASON, Col. 1st Dragoons, Commanding.

Brig. Gen. R. JONES, Adj. Gen. U. S. A., Was.h.i.+ngton, D. C.

[NOTE.--The original letter, of which this is a copy, was sent to its address, in charge of Lieut. L. Loeser, 3d Artillery, bearer of dispatches, who sailed in the schooner Lambayecana, from Monterey, Aug.

30, 1848, bound for Payta, Peru. Lieut. Loeser bears, in addition to the specimens mentioned in the foregoing letter, a tea-caddy containing two hundred and thirty ounces fifteen pennyweights and nine grains of gold.

This was purchased at San Francis...o...b.. my order, and is sent to you as a fair sample of the gold obtained from the mines of the Sacramento. It is a mixture, coming from the various parts of the gold district.

PURITY OF CALIFORNIA GOLD DUST.

The numerous a.n.a.lyses which have been made show that the gold dust of California is remarkably pure. The editor of the Buffalo Commercial Advertiser, under date of December 20th, 1848, says:--

"A small quant.i.ty of California gold was shown us this morning. It was in grains, about the size and shape of flax seed. Altogether there was half an ounce. It was received by a gentleman of this city, who, last year, left a quant.i.ty of goods in California for sale on commission. A few days ago he received advices that his goods had been sold, and the proceeds remitted in gold dust to New York. The receipts from the mint show its great purity. The weight before melting was 428 ounces; after melting 417.

Nett value, $7,685.49."

Gold is seldom found, in any parts of the earth, more than 22 carats fine: and it will be seen by the following report lately made by an experienced smelter and refiner, Mr. John Warwick, of New York city, that the gold dust of California is as pure as that found in any part of this country.

Probably there is none in Europe purer:

"I have a.s.sayed the portion of gold dust, or metal, from California, sent me, and the result shows that it is fully equal to any found in our Southern gold mines.

I return you 103/4 grains out of the 12 which I have tested--the value of which is 45 cents. It is 211/2 carats fine--within half a carat of the quality of English sovereigns or American Eagles, and is almost ready to go to the mint.

The finest gold metal we get is from Africa, which is 221/2 to 23 carats fine. In Virginia we have mines where the quality of the gold is much inferior--some of it as low as 19 carats, and in Georgia the mines produce it nearly 22 carats fine.

The gold of California which I have now a.s.sayed, is fully equal to that of any, and much superior to some produced from the mines in our Southern States."

PHYSICAL GEOGRAPHY OF CALIFORNIA.

Whatever appertains to California, the new El Dorado of the southwest, is interesting to Americans and indeed to the whole civilized world. The following brief account, therefore, of its physical geography, compiled from authentic sources and carefully condensed, will readily receive the attention of the inquiring mind:

"Upper California extends, upon the Pacific, from the 32d parallel of lat.i.tude, about seven hundred miles north-westward to Oregon, from which it is divided, nearly in the course of the 42d parallel--that is in the lat.i.tude of Boston--by a chain of highlands called the Snowy Mountains; the Sierra Nevada of the Spaniards. Its boundaries on the west are not, as yet, politically determined by the Mexican government; nor do geographers agree with regard to natural limits in that direction. By some, it is considered as embracing only the territory between the Pacific and the summit of the mountains which border the western side of the continent: others extend its limits to the Colorado; while others include in it, and others again exclude from it, the entire regions drained by that river.

The only portion occupied by Mexicans, or of which any distinct accounts have been obtained, is that between the great chain of mountains and the ocean; the country east of that ridge to the Colorado appears to be an uninhabitable desert.

"Northward from the Peninsula, or Lower California, the great western-most chain of mountains continues nearly parallel with the Pacific coast, to the 34th degree of lat.i.tude, under which rises Mount San Bernardin, one of the highest peaks in California, about forty miles from the ocean. Further north the coast turns more to the west, and the s.p.a.ce between it and the summit line of the mountains becomes wider, so as to exceed eighty miles in some places; the intermediate region being traversed by lines of hills, or smaller mountains, connected with the main range. The princ.i.p.al of these inferior ridges extends from Mount San Bernardin north-westward to its termination on the south side of the entrance of the Bay of San Franciso, near the 38th degree of lat.i.tude, where it is called the San Bruno Mountains. Between this range and the coast run the San Barbara Mountains, terminating on the north at the Cape of Pines, on the south- west side of the Bay of Monterey, near the lat.i.tude 361/2 degrees. North of the San Bruno mountains is the Bolbones ridge, bordering the Bay of San Francisco on the east; and still further in the same direction are other and much higher lines of highlands, stretching from the great chain and terminating in capes on the Pacific.

"The southern part of Upper California, between the Pacific and the great westernmost chain of mountains, is very hot and dry, except during a short time in winter. Further north the wet season increases in length, and about the Bay of San Francisco the rains are almost constant from November to April, the earth being moistened during the remainder of the year by heavy dews and fogs. Snow and ice are sometimes seen in the winter on the sh.o.r.es of the bay, but never further south, except on the mountain tops.

The whole of California is, however, subject to long droughts." Heavy rains are of rare occurrence, and two years without any is not unusual; notwithstanding which, vegetation does not suffer to the extent that might be inferred, because, in the first place, many small streams descend from the mountain ranges, supplying the means of both natural and artificial irrigation; and, next, that the country near the coast is favored with a diurnal land and sea breeze; and, from the comparatively low temperature of the sea, the latter is always in summer accompanied with fogs, in the latter part of the night, and which are dissipated by the morning's sun, but serve to moisten the pastures and nourish a somewhat peculiar vegetation abounding in beautiful flowers.

"Among the valleys of Upper California are many streams, some of which discharge large quant.i.ties of water in the rainy season; but no river is known to flow through the maritime ridge of mountains from the interior to the Pacific, except perhaps the Sacramento, falling into the Bay of San Francisco, though several are thus represented on the maps. The valleys thus watered afford abundant pasturage for cattle, with which they are covered; California, however, contains but two tracts of country capable of supporting large numbers of inhabitants, which are that west of Mt. San Bernardin, about the 34th degree of lat.i.tude, and that surrounding the Bay of San Francisco, and the lower part of the Sacramento; and even in these, irrigation would be indispensable to insure success in agriculture."

"The provincial terms of New Mexico, and of Upper and Lower California, have been, and are yet, rather designations of indefinite tracts than of real defined political sections. The Pacific ocean limits on the west, and by treaty, N. lat. 42 on the north; but inland and southward, it is in vain to seek any definite boundary. In order, however, to give as distinct a view as the nature of the case will admit, let us adopt the mouth of the Colorado and Gila, or the head of the Gulf of California, as a point on the southern boundary of Upper California. The point a.s.sumed coincides very nearly with N. lat. 32 and, if adopted, would give to that country a breadth of ten degrees of lat.i.tude or in round numbers 800 statute miles from south to north. As already, stated, the Pacific Ocean bounds this country on the west, and lat. 42 on the north. To separate it on the east from New Mexico, we must a.s.sume the mountain chain of Sierra Madre, or Anahuac, which, in this region, inclines but little from north to south: whilst the Pacific coast extends in general course north-west and south- east. These opposite outlines contract the southern side to about 500 miles, and open the northern side to rather above 800 miles; giving a mean breadth of 650 miles. The area, for all general purposes, may be safely taken at 500,000 square miles. The general slope or declination of this great region is westward, towards the Pacific and Gulf of California."

"The climate of the western slope of North America has a warmth ten degrees at least higher than the eastern, upon similar lat.i.tude. The cause of this difference is the course of prevailing winds in the temperate zones of the earth, from the western points. Thus the winds on the western side of the continent are from the ocean, and on the eastern from the land.

"The soil is as variable as the face of the country. On the coast range of hills there is little to invite the agriculturist, except in some vales of no great extent. The hills are, however, admirably adapted for raising herds and flocks, and are at present the feeding-grounds of numerous deer, elk, &c., to which the short, sweet gra.s.s and wild oats that are spread over them afford a plentiful supply of food. The valley of the Sacramento, and that of San Juan, are the most fruitful parts of California, particularly the latter, which is capable of producing wheat, Indian corn, rye, oats, &c., with all the fruits of the temperate, and many of the tropical climates. It likewise offers pasture grounds for cattle. This region comprises a level plain, from fifteen to twenty miles in width, extending from the Bay of San Francisco, beyond the mission of that name, north and south. This may be termed the garden of California; but although several small streams and lakes serve to water it, yet in dry seasons or droughts, not only the crops but the herbage also suffers extremely, and the cattle are deprived of food." The most extensive portion of Upper California--the inland plain between the California and the Colorado range of mountains--is an arid waste, dest.i.tute of the requisites for supplying the wants of man. This plain is a waste of sand, with a few detached mountains (some of which rise to the region of perpetual snow,) whose positions are unknown; from these flow small streams that are soon lost in the sand. A few Indians are scattered over the plain, the most miserable objects in creation."

The climate is very peculiar, the thermometer on the coast ranging as high, on the average, in winter as in summer. Indeed, summer is really the coldest and most disagreeable part of the year, owing to the north-west winds which frequently prevail during that season. As you recede from the coast, however, the climate undergoes a great change for the better. At San Juan, thirty miles from the coast, is one of the most delightful climates in the world. The two princ.i.p.al rivers in Upper California are the Sacramento and the San Joaquim. There are, however, many smaller streams flowing through the different valleys, which serve, during the dry season, to irrigate the land. The only navigable stream is the Sacramento.

Beside the bays and harbors of Monterey, Santa Barbara and San Pedro, Upper California possesses the harbor of San Francisco, within a few miles of the Gold Mines, and one of the largest and most magnificent harbors in the world.

The yield of wheat, small grain, and vegetables, is said to be great, and very remarkable, but, as agriculture cannot succeed in Upper California, but by irrigation, it has. .h.i.therto happened that it has been princ.i.p.ally occupied as a pastoral country--as costing less labor to rear cattle, for which it is only necessary to provide keepers, and have them marked. The numerous animals which are there slaughtered for little more than their hides and tallow, do not putrify and become offensive as they would in other climates, but, as wood is not everywhere as abundant as their bones, the last are sometimes used to supply the place of the former, in the construction of garden fences &c.

"The area of Upper California is about 500,000 square miles, and the population, exclusive of Indians scattered over this extent, as follows:

Californians descended from Spain,----------------- 4000 Americans from United States,---------------------- 360 English, Scotch, and Irish,------------------------ 300 European Spaniards,-------------------------------- 80 French and Canadians,------------------------------ 80 Germans, Italians, Portugese, and Sandwich Islanders, 90 Mexicans,------------------------------------------ 90 ____ Total---------------------------------------------- 5000

"Upper California is, on the whole, admirably fitted for colonization.

This province presents the greatest facilities for raising cattle, for cultivating corn, plants, and for the grape; it might contain twenty millions of inhabitants; and its ports are a point of necessary communication for vessels going from China and Asia to the western coasts of North America.

"It is beyond doubt, that so soon as an intelligent and laborious population is established there, this country will occupy an elevated rank in the commercial scale; it would form the _entrepot_ where the coasts of the great ocean would send their products, and would furnish the greatest part of their subsistence in grains to the north-west, to Mexico, to Central America, to Ecuador, to Peru, to the north coast of Asia, and to many groups of Polynesia--such as the Sandwich isles, the Marquesas, and Tahiti."

"The peninsula of Lower California, extending from Cape San Lucas to the Bay of Todos Santos, in lat. 32 N., on the Pacific, and to the mouth of the Colorado on the Gulf side, is a pile of volcanic debris and scoriae.

Much of the surface is still heated by subterranean fires. No craters are in action; but hot springs of water and bitumen, and frequent earthquakes, and the scorched face of the whole region, demonstrate it to be a mere ma.s.s upheaved from the sea, and burned to cinders. The range of mountains that comes up through Lower California, runs on northwardly into Upper California, at an average distance of sixty or seventy miles from the sea, till it falls away into low hills south of the bay of San Francisco. This, also, is a volcanic range; though not so strongly marked to that effect in the Upper as in the Lower Province.

"Some portions of this range are lofty. That part lying east and southeast of El Pueblo de los Angelos, is tipped with perpetual snows. But the greater part of it presents a base covered up to more than half of the whole elevation with pine and cedar forests; the remaining height being composed of bare, dark, glistening rocks, lying in confused ma.s.ses, or turreted in the manner observed on the Black Hills in the Great Prairie Wilderness---spires, towers, and battlements, lifted up to heaven, among which the white feathery clouds of beautiful days rest s.h.i.+ning in the mellow sun.

"The Snowy Mountain range is perhaps the boldest and most peculiar of the California highlands. Its western terminus is Cape Mendocino, a bold snow- capped headland, bending over the Pacific in 40 north lat.i.tude. Its western terminus is in the Wind River Mountains, lat.i.tude 42 N., about seven hundred miles from the sea. Its peculiarity consists in what may be termed its confused geological character. Near the sea its rocks are primitive, its strata regular. A hundred miles from the sea where the President's range crosses it, everything is fused--burned; and at the distance of seventy miles northeastwardly from the Bay of San Francisco, a spur comes off with a lofty peak, which pours out immense quant.i.ties of lava, and shoots up a flame so broad and bright as to be seen at sea, and to produce distinct shadows at eighty miles' distance. Here is an extensive tract of this range which has been burned, and whose strata have been torn from their natural positions; displaying an amalgamated ma.s.s of primitive rock _ex loco_, mingled with various descriptions of volcanic remains. From this point eastward, it is a broken irregular chain of peaks and rifted collateral ranges, and spurs running off northwardly and southwardly, some of which are primitive and others volcanic.

"Another range of mountains which deserves notice in this place, is that which bounds the valley of the San Joaquim on the east. This is a wide and towering range. It is in fact a continuation of the President's range, and partakes very strongly of its volcanic character. That part of it which lies eastwardly from the Bay of San Francisco, is very broad and lofty.

One of its peaks, Mount Jackson, as it is called, is the highest in all the President's range. Mountains of great size are piled around it, but they appear like molehills beside that veteran mount. Its vast peak towers over them all several thousand feet, a glittering cone of ice.

"All over the Californias, the traveler finds evidences of volcanic action. Far in the interior, among the deserts; in the streams; in the heights; in the plains; everywhere, are manifestations of the fact, that the current of subterranean fire which crossed the Pacific, throwing up that line of islands lying on the south of the Sea of Kamschatka, and pa.s.sed down the continent, upheaving the Oregon territory, did also bring up from the bed of the ocean the Californias.

"The peninsula, or lower California, which extends from Cape San Lucas in N. lat. 22 48', to the Bay of Todos Santos in lat. 32 N., is a pile of barren, volcanic mountains, with very few streams, and still fewer spots of ground capable of sustaining vegetation. The territory lying north and south of the Colorado of the west, and within the boundaries of the Californias, is a howling desolation.

"From the highlands near the mouth of the Rio Colorado, a wild and somewhat interesting scene opens. In the east appears a line of mountains of a dark hue, stretching down the coast of the Gulf as far as the eye can reach. These heights are generally dest.i.tute of trees; but timber grows in some of the ravines. The general aspect, however, is far from pleasing.

There is such a vastness of monotonous desolation; so dry, so blistered with volcanic fires; so forbidding to the wants of thirsting and hungering men, that one gladly turns his eye upon the water, the _Mar de Cortez_, the Gulf of California. The Colorado, two and a half miles in width, rushes into this Gulf with great force, las.h.i.+ng as it goes the small islands lying at its mouth, and for many leagues around the waters of the Gulf are discolored by its turbulent flood. On the west, sweep away the mountains of Lower California. These also are a thirsty ma.s.s of burned rocks, so dry that vegetation finds no resting-place among them.

"That province of Lower California varies from thirty to one hundred and fifty miles in width, a superficial extent almost equal to that of Great Britain; and yet on account of its barrenness, never will, from the products of the soil, maintain five hundred thousand people in a state of comfort, ordinarily found in the civilized condition. Every few years tornadoes sweep over the country with such violence, and bearing with them such floods of rain, that whatever of soil has been in any manner previously formed, is swept into the sea. So that even those little nooks among the mountains, where the inhabitants from time to time make their fields, and task the vexed earth for a scanty subsistence, are liable to be laid bare by the torrents. In case the soil chance to be lodged in some other dell, before it reach the Ocean or the Gulf, and the people follow it to its new location, they find perhaps no water there and cannot cultivate it. Consequently they are often driven by dreadful want to some other point in quest of sustenance, where they may not find it, and perish among the parched highlands. The mean range of temperature in the whole country in the summer season is from 60 to 74 Fahrenheit. The rains fall in the winter months; are very severe, and of short duration. During the remainder of the year the air is dry and clear; and the sky more beautiful than the imagination can conceive.

"The range of mountains occupying the whole interior of this country, vary in height from one to five thousand feet above the level of the sea. They are almost bare of all verdure, mere brown piles of barrenness, sprinkled here and there with a cl.u.s.ter of briars, small shrubs, or dwarf trees.

Among the ridges are a few spots to which the sweeping rains have spared a little soil. These, if watered by springs or streams, are beautiful and productive. There are also a few places near the coast which are well adapted to tillage and pasturage.

"But the princ.i.p.al difficulty with this region, is one common to all countries of volcanic, origin,--a scarcity of water. The porousness of the rocks allows it to pa.s.s under ground to the sea. Consequently one finds few streams and springs in Lower California. From the Cape San Lucas to the mouth of the Colorado, six hundred miles, there are only two streams emptying into the Gulf. One of these is called San Josef del Cabo. It pa.s.ses through the plantations of the Mission bearing the same name, and discharges itself into the bay of San Barnabas. The other is the Mulege, which waters the Mission of Santa Rosalia, and enters the Gulf in lat.i.tude 27 N. These are not navigable. The streams on the ocean coast, also, are few and small. Some of them are large enough to propel light machinery, or irrigate considerable tracts of land, but none of them are navigable. In the interior are several large springs, which send out abundant currents along the rocky beds of their upper courses; but when they reach the loose sands and porous rocks of the lower country, they sink and enter the sea through subterranean channels. A great misfortune it is too, that the lands which border those portions of these streams which run above the ground, consist of barren rocks. Where springs, however, and arable land occur together, immense fertility is the consequence. There is some variety of climate on the coasts, which it may be well to mention. On the Pacific sh.o.r.e the temperature is rendered delightfully balmy by the sea breezes, and the humidity which they bring along with them. Fahrenheit's thermometer ranges on this coast, during the summer, between fifty-eight and seventy-one degrees. In the winter months, while the rains are falling, it sinks as low as fifty degrees above zero. On the Gulf coast there is a still greater variation. While at the Cape, the mercury stands between sixty and seventy degrees, near the head of the Gulf it is down to the freezing point.

"These isolated facts, in regard to the great territory under consideration, will give the reader as perfect an idea of the surface and agricultural capacities of Lower California as will be here needed.
