The Russian American Company had a large establishment at Ross and Bodega, ninety miles north of San Francisco, founded in the year 1812; and factories were also established in the territory by the Hudson Bay Company. Their agents and _employes_ ransacked the whole country west of the Sierra Nevada, or Snowy Mountain, in search of game. In 1838, Captain Sutter, formerly an officer in the Swiss Guards of Charles X., King of France, emigrated from the state of Missouri to Upper California, and obtained from the Mexican government a conditional grant of thirty leagues square of land, bounded on the west by the Sacramento river. Having purchased the stock, arms, and ammunition of the Russian establishment, he erected a dwelling and fortification on the left bank of the Sacramento, about fifty miles from its mouth, and near what was termed, in allusion to the new settlers, the American Fork. This formed the nucleus of a thriving settlement, to which Captain Sutter gave the name of New Helvetia. It is situated at the head of navigation for vessels on the Sacramento, in latitude 38° 33' 45" north, and longitude 121° 20' 05" west. During a residence of ten years in the immediate vicinity of the recently discovered _placéras_, or gold regions, Captain Sutter was neither the wiser nor the richer for the brilliant treasures that lay scattered around him.[2] In the year 1841, careful examinations of the Bay of San Francisco, and of the Sacramento River and its tributaries, were made by Lieutenant Wilkes, the commander of the Exploring Expedition; and a party under Lieutenant Emmons, of the navy, proceeded up the valley of the Willamette, crossed the intervening highlands, and descended the Sacramento. In 1843-4, similar examinations were made by Captain, afterwards Lieutenant-Colonel Fremont, of the Topographical Engineers, and in 1846, by Major Emory, of the same corps. None of these officers made any discoveries of minerals, although they were led to conjecture, as private individuals who had visited the country had done, from its volcanic formation and peculiar geological features, that they might be found to exist in considerable quantities.[3]
