BOSTON.—This town is located on the American Fork at its junction with the Sacramento. The plot of the town is beautiful—its situation agreeable. Direct roads issue from it to the placers of the Yuba, Feather river, the North, Middle, and South forks of the Americano. Like Sacramento City, it is located within the grant of Capt. Sutter, whose title to the enterprising proprietors will undoubtedly be found valid. Several buildings have been erected, which give an air of stability to the flapping tents which shadow its avenues. STOCKTON.—This flourishing town is located at the head of an arm of the Suisun bay, and is accessible to small steamers. It stands in the centre of a vast fertile plain, and on a position sufficiently elevated to exempt it from inundation. It is the commercial depot for the southern mines; the miners on the Mokelumne, Stanislaus, Tuolumne, Mariposa, Mercedes, and King’s river, are supplied with provisions and clothing from its heavy storehouses. It will yet loom largely in the map of California. NEW YORK.—This town is located on the triangle formed by the junction of the San Joaquin river and Suisun bay, with its base resting on a broad plain, covered with clusters of live-oak. The banks of the river and bay are bold, and above the reach of tide and freshet. The bay is represented on the surveys which have been made as having sufficient depth for merchantmen of the largest class. The communication with the sea lies through the broad strait of the Carquinas. The town will naturally command the commerce of the San Joaquin and its numerous tributaries. The projectors of the town are Col. Stevenson and Dr. Parker. ALVEZO.—This town is situated at the head of the great bay of San Francisco, on the Gaudalupe, which flows through it. It is the natural depot of the commerce which will roll in a broad exhaustless tide, through the fertile valleys of Santa Clara and San José. It lies directly in the route to the gold and quicksilver mines, with a climate not surpassed by that of any locality in the northern sections of California. The fertility of the surrounding country must ere long make itself felt in the growth and prosperity of this town. San Francisco is dependant on the products of its horticulture. Fortunes might be made by any persons who would go there and devote themselves exclusively to gardening. But it is not in man to raise cabbages in a soil that contains gold. The proprietors of the town are J. D. Hoppe, Peter H. Burnett, and Charles B. Marvin.
