Our trip after leaving your city, by way of Pueblo, San Jose, and the San Joaquin river, we found very agreeable. Pa.s.sing over a lovely country, with its valleys and hills covered with the richest verdure, intertwined with flowers of every hue. The country from the San Joaquin river to this place, is rich beyond comparison, and will admit of a dense population.

We found the fort a miniature Manchester, a young Lowell. The blacksmith's hammer, the tinner, the carpenter, and the weaver's shuttle, plying by the ingenuity of Indians, at which place there are several hundred in the employ of Capt. J.A. Sutter. I was much pleased with a walk in a large and beautiful garden attached to the fort. It contains about eight or ten acres, laid out with great taste, under the supervision of a young Swiss.

Among the fruit trees I noticed the almond, fig, olive, pear, apple, and peach. The grape vines are in the highest state of cultivation, and for vegetables, I would refer you to a seedman's catalogue.

About three miles from the fort, on the east bank of the Sacramento, the town of Suttersville is laid out. The location is one of the best in the country, situated in the largest and most fertile district in California, and being the depot for the extensive, gold, silver, platina, quicksilver, and iron mines. A hotel is now building for the accomodation of the travelling public, who are now obliged to impose on the kind hospitalities of Capt. Sutter. A party of men who have been exploring a route to cross the Sierra Nevada mountains, have just returned, and report that they have found a good wagon road on the declivity ridge between the American fork and the McCossamy rivers, the distance being much less than by the old route. The road will pa.s.s through the gold district, and enter the valley near the American fork.

A ferry is to be established at Suttersville, on the Sacramento, and the road across the _tularie_ improved soon, which will shorten the distance from this place to Sonoma and your city, about 60 miles.

After leaving the fort we pa.s.sed up on the south bank of the American fork, about twelve miles. This is a beautiful river, about three fathoms deep the water being very cold and clear; and after leaving the river we pa.s.sed through a country rolling and timbered with oak. We soon commenced ascending the hills at the base of the Sierra Nevada, which are thickly set with oak and pine timber, and soon arrived at a small rivulet. One of our party dipped up a cupful of sand from the bed of the creek, washed it, and found five pieces of gold. This was our first attempt at gold digging.

About dark we arrived at the saw-mill of Captain Sutter, having ridden over gold, silver, platina and iron mines, some twenty or thirty miles.

The past three days I have spent in exploring the mountains in this district, and conversing with many men who have been at work here for some weeks past. Should I attempt to relate to you all that I have seen, and have been told, concerning the extent and productions of the mines, I am fearful your readers would think me exaggerating too much, therefore I will keep within bounds. I could fill your columns with the most astonishing tales concerning the mines here, far excelling the Arabian Nights, and all true to the letter.

As near as I can ascertain, there are now about 2,000 persons engaged, and the roads leading to the mines are thronged with people and wagons. From one to nine ounces of pure virgin gold per day is gathered by every man who performs the requisite labor. The mountains have been explored for about forty miles, and gold has been found in great abundance in almost every part of them. A gentleman informed me that he had spent some time in exploring the country, and had dug fifty-two holes with his butcher's knife in different places, and found gold in every one.

Several extensive silver mines have been discovered, but very little attention is paid to them now. Immense beds of iron ore, of superior quality, yielding 85 to 90 per cent., have also been found near the American Fork.

A grist mill is to be attached to the saw mill, for the purpose of convenience of families and others settling at the mines. The water power of the American Fork is equal to any upon this continent, and in a few years large iron founderies, rolling, splitting and nail mills will be erected.

The granite of the mountains is superior to the celebrated Quincy. A quarry of beautiful marble has been discovered near the McCossanny river, specimens of which you will see in a few years in the front of the Custom House, Merchants' Exchange, City Hall, and other edifices in your flourishing city.

P. S.-"The cry is still, they come." Two men have just arrived for provisions from the Abjuba river, who state that they have worked five days, and gathered $950 in gold, the largest piece weighing nearly one ounce. They report the quant.i.ty on that river to be immense, and in much larger pieces than that taken in other parts.

SONOMA. Aug. 5, 1848.

The mining fever is raging here, as well as elsewhere. Not a mechanic or laboring man can be obtained in town, and most of our male citizens have "gone up" to the Sierra Nevada, and are now enjoying "golden moments."

Spades, shovels, pick-axes, hoes, bottles, vials, snuff-boxes, bra.s.s tubes, earthern jars, and even barrels, have been put in requisition, and have also abruptly left town.

I have heard from one of our citizens who has been at the Gold Placer a few weeks, and he had collected $1,500 worth of the "root of evil," and was still averaging $100 per day. Another gent, wife and boy collected $500 worth in one day. Another still, who shut up his hotel here some five or six weeks since, has returned with $2,200 in pure virgin gold, collected by his own exertions, with no other aid than a spade, pick and Indian basket.

Three new and valuable lead mines have recently been discovered in this vicinity, and one of our citizens, Mr. John Bowles, of Galena, Ill.--a gent, who has been reported by the Boston press as having been murdered by the Indians, on the Southern route to Oregon, from the States--informed me that the ore would yield 90 per cent., and that it was his intention to erect, as soon as practicable, six large smelting furnaces.

The Colonnade Theatre, at this place, has closed for the season; it was well attended, however, from the time the Thespians made their debut till they made their exit. The "Golden Farmer," the "Omnibus," and a Russian comedy called "Feodora,' (translated from the German of Kotzebue, by Mr.

F. Linz, of Sonoma,) were their last attractions.

The military company under command of Capt. J. E. Brackett, are today exchanging posts with Company H., under command of Captain Frisbie, both of the New York Volunteers. Company C. has been stationed with us more than a year, and much praise is due its members, not only for the military and soldier-like manner in which they have acquitted themselves as a corps, but for their gentlemanly and orderly deportment individually and collectively. We regret to part with them, and cannot let them go without expressing a hope that when peace shall have been declared, their regiment disbanded, and their country no longer needs their services, they may have fallen sufficiently in love with our healthy climate and our beautiful valley to come back and settle.

GOLD.

The New York _Evening Post_ has an article upon this subject, from which we take the following:

The places where it is found are much more numerous than we might at first suppose. The mines of America, however, surpa.s.s those of all other countries. Though of comparative newness, they have furnished three times and a half more gold and twelve times more silver than those of the old world. Silver and gold were, before the discovery of America, supposed to bear to each other the relation of 55 to 1. In Europe the proportion is now about 15 to 1.

The gold of Mexico is chiefly found in argentiferous veins, as at Guanaxuato, where it is obtained one ounce in 360. The only auriferous veins, worked as such, are at Oaxaca. The rivers in Caraccas flow over auriferous sands. Peru is not reported rich in gold at present. The gold of New Grenada is found in alluvial soil, and is washed out in the shape of spangles and grains. The gold of Chili, is found under similar circ.u.mstances. Brazil formerly brought the most gold to market, not even excepting Russia, which now, however, surpa.s.ses her. All the rivers running from the Brazilian mountains have gold, and the annual product of fine metal is now rated at $5,000,000.

There are no very late tables of the products of the American mines. We have ascertained, by accident purely, how the estimate is made at present.

From 1790 to 1830, forty years, the product of Mexico was:--

Gold 6,436,453 Silver 139,818,032

Chili--

Gold 2,768,488 Silver 1,822,924

Buenos Ayres--

Gold 4,024,895 Silver 27,182,673

Add to this Russia--

Gold 2,703,743 Silver 1,502,981

And we have from four countries alone 1880 millions of pounds sterling, or forty-seven millions per annum.

If we add the products of Europe and Asiatic Russia, of the East Indies and Africa, which some estimate at thirty-six tons of gold per annum, we perceive that a vast amount of the precious metal is unearthed and somewhere in use. The relative value of gold has certainly changed very much within a few hundred years, and it probably will change still more.

But we do not think it is likely to depreciate one-half in our time, for many reasons, though some persons imagine it will.

The true secret of all this present excitement is this: the Anglo Saxon race, for the first time in their history, own and occupy gold mines of very great value. Hitherto Africans, Asiatic or Indians, have held them, and they have never shown that ardor combined with perseverance which belongs to us. England never had any mines of gold, or she would have worked them as diligently as she has those of coal. The Americans have now a golden chance, and they are the first of their blood that have ever had it. They will be sure to turn the opportunity to account.

At our leisure we will refer to some other interesting facts, in relation to the value of gold at different periods. We conclude with recalling one singular circ.u.mstance to the recollection of our readers, that when the Romans captured Jerusalem, they obtained so much gold, that the price of it in Syria fell one half.

LIEUTENANT L. LOESER, of the Third Artillery, a graduate of West Point, furnishes the following information respecting the gold region:

"We have been favored by Lieutenant Loeser, bearer of dispatches from Governor Mason to the government at Washington (who also brought on about $20,000 of gold dust, which he deposited at Washington,) with a general description of the gold region, the climate, &c., of California. He says the gold region is very large, and there is sufficient ore to profitably employ one hundred thousand persons for generations to come. So far as discovered, the gold is found in an extent of country four hundred miles long, by one hundred and fifty wide, and no particular portion seems more productive than another. In the river and on the flatlands the gold dust is found; but among the rocks and in the highlands it is found in lumps, from the size of a man's hand to the size of an ordinary duck-shot, all of which is solid, and presents the appearance of having been thrown up by a volcanic eruption. So plenty is the gold, that little care is paid to the washing of it by those engaged when he left; the consequence of which is great quant.i.ties are thrown away. In the highlands he was walking with a man who found a piece weighing about thirty-five pennyweights, worth $29, but which he purchased for $4. The piece is solid, and has the form of a perfect acorn on the top of it. He has had it, just as it was found, converted into a breastpin. A man, by ordinary labor, may procure from $50 to $200 per day. With regard to the climate, he says, it is salubrious, at no time being so cold as to require more than a light blanket to sleep under. When he left, the people were sleeping under the trees, without the fear of sickness from exposure. The rainy season begins about the first of November, and continues until March, though there are five clear days for every rainy one. Provisions are generally high, at least such as cannot be obtained in the country. Flour is worth $80 per barrel, though a fine bullock may be obtained for $3. Clothing is very high, and the demand is very great. The Indians, who have heretofore used no clothing whatever, now endeavor to imitate the whites, and will give any price for garments.

The report relative to the Mormons requiring 30 per cent. of all the gold found, he says, is a mistake. When the gold was first discovered, one of the leaders of that people demanded that amount from all the Mormons, but they remonstrated, and refused to pay it, which remonstrance caused not the slightest difficulty among the people. He was in San Francisco when the gold was first discovered, about forty miles from that place. The news was received one day, and the following morning, out of the whole company to which he was attached, every one deserted except two sergeants, and took with them all the horses belonging to the officers. In a few days the city was almost entirely deserted, and Col. Mason, the governor of the territory, was, and has ever since been, obliged to prepare and cook his own food. A servant cannot be had at any price; and the soldiers have not sufficient pay for a month to subsist on for a week. The salary of the governor is not sufficient to support him; and, like all others in the more wealthy circles of life, he is obliged to be his own servant. He speaks of the country as offering the greatest inducements to young men of enterprise, and thinks there is ample room and gold for hundreds of thousands.

ADVICE TO THOSE GOING TO CALIFORNIA BY THE CAPES.

The following article, condensed from correspondence in a daily paper of New York City, will be found to contain many valuable hints to the California bound traveler. It came to hand too late to appear in its proper place, where the four different routes are spoken of:
