There are a lot of different stories about the discovery of gold at Coloma by James Wilson Marshall. Some were written by people who were alive at the time, some were written by historians at a much later time. This one was written by John Sutter, who contracted with Marshall to build the mill at Coloma.
It was published less than ten years after the discovery in Hutchings’ California Magazine’s issue of November 1857. It has been serialized into three parts to fit.
It was in the first part of January, 1848, when the gold was discovered at Coloma, where I was then building a saw-mill. The contractor and builder of this mill was James W. Marshall, from New Jersey. In the fall of 1847, after the mill seat had been located, I sent up to this place Mr. P. L. Wimmer with his family, and a number of laborers, from the disbanded Mormon Battalion; and a little later I engaged Mr. Bennet from Oregon to assist Mr. Marshall in the mechanical labors of the mill. Mr. Wimmer had the team in charge, assisted by his young sons, to do the necessary teaming, and Mrs. Wimmer did the cooking for all hands.
I was very much in need of a new saw-mill, to get lumber to finish my large flouring mill, of four run of stones, at Brighton, which was commenced at the same time, and was rapidly progressing; likewise for other buildings, fences, etc., for the small village of Yerba Buena, (now San Francisco.) In the City Hotel, (the only one) at the dinner table this enterprise was unkindly called “another folly of Sutter’s,” as my first settlement at the old fort near Sacramento City was called by a good many, “a folly of his,” and they were about right in that, because I had the best chances to get some of the finest locations near the settlements; and even well stocked rancho’s had been offered to me on the most reasonable conditions; but I refused all these good offers, and preferred to explore the wilderness, and select a territory on the banks of the Sacramento. It was a rainy afternoon when Mr. Marshall arrived at my office in the Fort, very wet. I was somewhat surprised to see him, as he was down a few days previous; and then, I sent up to Coloma a number of teams with provisions, mill irons, etc., etc. He told me then that he had some important and interesting news which he wished to communicate secretly to me, and wished me to go with him to a place where we should not be disturbed, and where no listeners could come and hear what we had to say. I went with him to my private rooms; he requested me to lock the door; I complied, but I told him at the same time that nobody was in the house except the clerk, who was in his office in a different part of the house; after requesting of me something which he wanted, which my servants brought and then left the room, Photograph of John Marshall, who discovered gold forgot to lock the doors, and it happened that the door was opened by the clerk just at the moment when Marshall took a rag from his pocket, showing me the yellow metal: he had about two ounces of it; but how quick Mr. M. put the yellow metal in his pocket again can hardly be described. The clerk came to see me on business, and excused himself for interrupting me, and as soon as he had left I was told, “now lock the doors; didn’t I tell you that we might have listeners?” I told him that he need fear nothing about that, as it was not the habit of this gentleman; but I could hardly convince him that he need not to be suspicious. Then Mr. M. began to show me this metal, which consisted of small pieces and specimens, some of them worth a few dollars; he told me that he had expressed his opinion to the laborers at the mill, that this might be gold; but some of them were laughing at him and called him a crazy man, and could not believe such a thing.
After having proved the metal with aqua fortis, which I found in my apothecary shop, likewise with other experiments, and read the long article “gold” in the Encyclopedia Americana, I declared this to be gold of the finest quality, of at least 23 carats. After this Mr. M. had no more rest nor patience, and wanted me to start with him immediately for Coloma; but I told him I could not leave as it was late in the evening and nearly supper time, and that it would be better for him to remain with me till the next morning, and I would travel with him, but this would not do: he asked me only “will you come to-morrow morning?” I told him yes, and off he started for Coloma in the heaviest rain, although already very wet, taking nothing to eat. I took this news very easy, like all other occurrences good or bad, but thought a great deal during the night about the consequences which might follow such a discovery. I gave all my necessary orders to my numerous laborers, and left the next morning at 7 o’clock, accompanied by an Indian soldier, and vaquero, in a heavy rain, for Coloma. About half way on the road I saw at a distance a human being crawling out from the brushwood. I asked the Indian who it was: he told me “the same man who was with you last evening.” When I came nearer I found it was Marshall, very wet; I told him that he would have done better to remain with me at the fort than to pass such an ugly night here but he told me that he went up to Coloma, (54 miles) took his other horse and came half way to meet me; then we rode up to the new Eldorado. In the afternoon the weather was clearing up, and we made a prospecting promenade.
