Thursday, April 26. The gold region, which contains deposits of sufficient richness to reward the labor of working them, is strongly defined by nature. It lies along the foot hills of the Sierra Nevada—a mountain range running nearly parallel with the coast—and extends on these hills about five hundred miles north and south, by thirty or forty east and west. From the slopes of the Sierra, a large number of streams issue, which cut their channels through these hills, and roll with greater or less volume to the Sacramento and San Joaquin rivers. The Sacramento rises in the north, and flowing south two hundred and fifty miles, empties itself into the Suisun, or upper bay of San Francisco. The San Joaquin rises in the south, and flowing north two hundred miles, discharges itself into the same bay. The source of the San Joaquin is a narrow lake lying still further south, and extending in that direction about eighty miles.

The streams which break into these rivers from the Sierra Nevada, are from ten to thirty miles distant from each other. They commence with Feather river on the north, and end with the river Reys on the south. They all have numerous tributaries; are rapid and wild on the mountain slopes, and become more tranquil and tame as they debouch upon the plain. Still their serpentine waters, flashing up among the trees which shadow their channels give a picturesque feature to the landscape, and relieve it of that monotony which would otherwise fatigue the eye. But very few of these rivers have sufficient depth and regularity to render them navigable. Their sudden bends, falls, and shallows would puzzle even an Indian canoe, and strand any boat of sufficient draft to warrant the agency of steam.

The alluvial deposits of gold are confined mainly to the banks and bars of these mountain streams, and the channels of the gorges, which intersect them, and through which the streams are forced when swollen by the winter rains. In the hills and table-lands, which occupy the intervals between these currents and gorges, no alluvial deposits have been found. Here and there a few detached pieces have been discovered, forming an exception to some general law by which the uplands have been deprived of their surface treasures. The conclusion at which I have arrived, after days and weeks of patient research, and a thousand inquiries made of others, is, that the alluvial deposits of gold in California are mainly confined to the banks and bars of her streams, and the ravines which intersect them. The only material exception to this general law is found in those intervening deposits, from which the streams have been diverted by some local cause, or some convulsion of nature. Aside from these, no surface gold to any extent has been found on the table-lands or plains. Even the banks of the Sacramento and San Joaquin, stretching a distance of five hundred miles through their valleys, have not yielded an ounce. The mountain streams, long before they discharge themselves into these rivers, deposit their precious treasures. They contribute their waters, but not their gold. Like cunning misers they have stowed this away, and no enchantments can make them whisper of its whereabouts. If you would find it, you must hunt for it as for hid treasures.

Monday, May 14. Much has been said of the amounts of gold taken from the mines by Sonoranians, Chilians, and Peruvians, and carried out of the country. As a general fact, this apprehension and alarm is without any sound basis. Not one pound of gold in ten, gathered by these foreigners, is shipped off to their credit: it is spent in the country for provisions, clothing, and in the hazards of the gaming-table. It falls into the hands of those who command the avenues of commerce, and ultimately reaches our own mints. I have been in a camp of five hundred Sonoranians, who had not gold enough to buy a month’s provisions—all had gone, through their improvident habits, to the capacious pockets of the Americans. To drive them out of California, or interdict their operations, is to abstract that amount of labor from the mines, and curtail proportionably the proceeds. If gold, slumbering in the river banks and mountains of California, be more valuable to us than when stamped into eagles and incorporated into our national currency, then drive out the Sonoranians: but if you would have it here and not there, let those diggers alone. When gold shall begin to fail, or require capital and machinery, you will want these hardy men to quarry the rocks and feed your stampers; and when you shall plunge into the Cinnebar mountains, you will want them to sink your shafts and kindle fires under your great quicksilver retorts. They will become the hewers of wood and drawers of water to American capital and enterprise. But if you want to perform this drudgery yourself, drive out the Sonoranians, and upset that cherished system of political economy founded in a spirit of wisdom and national justice.

Tuesday, May 22. I was in possession of a fact which left no doubt of the existence of gold in the Stanislaus more than a year prior to its discovery on the American Fork. A wild Indian had straggled into Monterey with a specimen, which he had hammered into a clasp for his bow. It fell into the hands of my secretary, W. R. Garner, who communicated the secret to me. The Indian described the locality in which it was found with so much accuracy that Mr. G., on his recent excursion to the mines, readily identified the spot. It is now known as “Carson’s diggings.” No one who has been there can ever forget its wild majestic scenery, or confound its soaring cliffs or sunless chasms with the images projected from other objects. It was the full intention of Mr. G. to trail this Indian at the first opportunity, and he was prevented from doing it only by the imperative duties of the office. His keeping the discovery a secret, proceeded less from any sinister motive than an eccentricity of character. He had another mineral secret which has not yet transpired—the existence of a tin mine, near San Louis Obispo. The extent is not known, but certainly the specimen shown me was very rich. Mr. Garner is now dead: it was his melancholy fate to fall with five others by the wild Indians on the river Reys. To that party I should have been attached had I remained in California another month. How narrow those escapes which run their mystic thread between two worlds! On the grave of my friend, gratitude for important services, and a remembrance of many sterling virtues, might well erect a memorial.

Thursday, May 24. The capabilities of the soil of California for agricultural purposes involve a question of profound interest, and one which is not easily answered. There are no experimental facts of sufficient scope to warrant a general conclusion. Where the soil itself leaves no doubt of its richness, its productive forces may be baffled by local circumstances or atmospheric phenomena. Some of the largest crops that have ever rewarded the toil of the husbandman, have been gathered in California; and yet those very localities, owing to a slender fall of the winter rains, have next season disappointed the hopes of the cultivator. The farmer can never be certain of an abundant harvest till he is able to supply this deficiency of rain by a process of irrigation. This can be done, in some places, by the diversion of streams, and must be accomplished in others through artesian wells. It will be some years before either will be brought into effective force in the agricultural districts.

The lands on which cultivation has been attempted occupy a narrow space between the coast ranges and the sea; it seldom exceeds in width thirty miles, and is often reduced to ten by the obtrusion of some mountain spur. East of this range no plough has ever travelled; no furrow has ever been turned in the long valley of the San Joaquin; and if the other sections of this valley correspond to those over which I passed, there can be very little encouragement for the introduction of husbandry. The soil is light and gravelly; the grass meagre and sparse; even the wild horses and elk seek its margin, as if afraid to trust themselves to the Sahara of its bosom. Still, in some of its bays, the evidences of fertility exist, but as a district it will never add much to the agricultural wealth of California.

The valley of the Sacramento has many localities of great fertility; but few of them, as yet, have been subjected to the plough and harrow; their adaptation to agriculture is inferred from their vigorous vegetation. The same evidences of productive force cover several tracts north of San Francisco, on the Russian river, and in the vicinity of Sonoma. But the most fertile lands in California, as yet developed, lie around the missions of Santa Clara and Santa Cruz, through the long narrow valleys of San José and San Juan, along the margin of the Salinas, through the dells of San Louis Obispo, and in the vicinity of los Angeles. These, and other insular spots, may be made perfect gardens; but take California as a whole, she is not the country which agriculturists would select. Her whole mining region is barren; nature rested there with what she put beneath the soil. You can hardly travel through it in midsummer without loading your mule down with provender to keep him alive. The productive forces of such a state as New York, Ohio, or Pennsylvania, sweep immeasurably beyond the utmost capabilities of California. It is the golden coronet that gives this land her pre-eminence, and puts into her hand a magic wand, that will shake for ages the exchanges of the civilized world.

Tuesday, June 12. At the return of Gen. Kearny, the command of the military posts of the country, the suppression of popular disturbancies, the protection of property from the incursion of the Indians, and the collection of the custom-house revenues have devolved on Gen. Mason. To these complicated duties he has surrendered his energies with an unwearied fidelity and force. No one great interest confided to his indomitable activity has languished. He has derived indispensable aid from the intelligent services of Col. Stevenson, Maj. Folsom, Capt. Halleck, and Lieut. Sherman, of the army, and Lieut. Lanman, of the navy. These officers, and others that might be named, without any increased compensation, and subjected to heavy expenses, have cheerfully discharged the onerous duties devolved upon them by the condition of the country.
