"All hands now began to search for the 'root of all evil.' Shortly after, Captain Sutter came to Coloma, and he and Marshall assembled the Indians and bought of them a large tract of country about Coloma, in exchange for a lot of beads and a few cotton handkerchiefs. They, under color of this Indian title, required one-third of all the gold dug on their domain, and collected at this rate until the fall of 1848, when a mining party from Oregon declined paying 'tithes' as they called it.
"During February, 1848, Marshall and Weimer went down the river to Mormon Island, and there found scales of gold on the rocks. Some weeks later they sent Mr. Henderson, Sydney Willis and Mr. Fifield, Mormons, down there to dig, telling them that that place was better than Coloma. These were the first miners at Mormon Island."
Marshall was a man of an active, enthusiastic mind, and he at once attached great importance to his discovery. His ideas, however, were vague; he knew nothing about gold-mining; he did not know how to take advantage of what he had found. Only an experienced gold-miner could understand the importance of the discovery and make it of practical value to all the world. That gold-miner, fortunately, was near at hand; his name was Isaac Humphrey. He was residing in the town of San Francisco, in the month of February, when a Mr. Bennett, one of the party employed at Marshall's mill, went down to that place with some of the dust to have it tested; for it was still a matter of doubt whether this yellow metal really was gold. Bennett told his errand to a friend whom he met in San Francisco, and this friend introduced him to Humphrey, who had been a gold-miner in Georgia, and was therefore competent to pass an opinion.
Humphrey looked at the dust, pronounced it gold at the first glance, and expressed a belief that the diggings must be rich. He made inquiries about the place where the gold was found, and subsequent inquiries about the trustworthiness of Mr. Bennett, and on March 7th he was at the mill. He tried to induce several of his friends in San Francisco to go with him; they all thought his expedition a foolish one, and he had to go alone. He found that there was some talk about the gold, and persons would occasionally go about looking for pieces of it; but no one was engaged in mining, and the work of the mill was going on as usual. On the 8th he went out prospecting with a pan, and satisfied himself that the country in that vicinity was rich in gold. He then made a rocker and commenced the business of washing gold, and thus began the business of mining in California.
Others saw how he did it, followed his example, found that the work was profitable, and abandoned all other occupations. The news of their success spread; people flocked to the place, learned how to use the rocker, discovered new diggings, and in the course of a few months the country had been overturned by a social and industrial revolution.
Mr. Humphrey had not been at work more than three or four days before a Frenchman, called Baptiste, who had been a gold-miner in Mexico for many years, came to the mill, and he agreed with Humphrey that California was very rich in gold. He, too, went to work, and, being an excellent prospector, he was of great service in teaching the newcomers the principles of prospecting and mining for gold—principles not abstruse, yet not likely to suggest themselves at first thought to men entirely ignorant of the business. Baptiste had been employed by Captain Sutter to saw lumber with a whipsaw, and had been at work for two years at a place, since called Weber, about ten miles eastward from Coloma. When he saw the diggings at the latter place, he at once said there were rich mines where he had been sawing, and he expressed surprise that it had never occurred to him before, so experienced in gold-mining as he was; but he afterward said it had been so ordered by Providence, that the gold might not be discovered until California should be in the hands of the Americans.
About the middle of March, P.B. Reading, an American, now a prominent and wealthy citizen of the State, then the owner of a large ranch on the western bank of the Sacramento River, near where it issues from the mountains, came to Coloma, and after looking about at the diggings, said that if similarity in the appearance of the country could be taken as a guide there must be gold in the hills near his ranch; and he went off, declaring his intention to go back and make an examination of them. John Bidwell, another American, now a wealthy and influential citizen, then residing on his ranch on the bank of Feather River, came to Coloma about a week later, and he said there must be gold near his ranch, and he went off with expressions similar to those used by Reading. In a few weeks news came that Reading had found diggings near Clear Creek, at the head of the Sacramento Valley, and was at work there with his Indians; and not long after, it was reported that Bidwell was at work with his Indians on a rich bar of Feather River, since called "Bidwell's Bar."
Although Bennett had arrived at San Francisco in February with some of the dust, the editors of the town—for two papers were published in the place at the time—did not hear of the discovery till some weeks later. The first published notice of the gold appeared in the Californian (published in San Francisco) on March 15th, as follows: "In the newly made raceway of the sawmill recently erected by Captain Sutter, on the American Fork, gold has been found in considerable quantities. One person brought thirty dollars' worth to New Helvetia, gathered there in a short time. California, no doubt, is rich in mineral wealth; great chances here for scientific capitalists. Gold has been found in almost every part of the country."
Three days later the California Star, the rival paper, gave the following account of the discovery: "We were informed a few days since that a very valuable silver-mine was situated in the vicinity of this place, and, again, that its locality was known. Mines of quicksilver are being found all over the country. Gold has been discovered in the northern Sacramento districts, about forty miles above Sutter's Fort. Rich mines of copper are said to exist north of these bays."
Although these articles were written two months after the discovery, it is evident that the editors had heard only vague rumors, and attached little importance to them. The Star of March 25th says: "So great is the quantity of gold taken from the new mine recently found at New Helvetia that it has become an article of traffic in that vicinity."
