Dr. Gillette, to whom we were indebted for many kind attentions, related to me the manner of his finding the rich gulch which attracted so many to the Mokelumne Diggings. About two months previous to our arrival, Dr. Gillette came down from the Upper Bar with a companion, to “prospect” for gold among the ravines in the neighborhood. There were no persons there at the time, except some Indians belonging to the tribe of José Jesus. One day at noon, while resting in the shade of a tree, Dr. G. took a pick and began carelessly turning up the ground. Almost on the surface, he struck and threw out a lump of gold of about two pounds weight. Inspired by this unexpected result, they both went to work, laboring all that day and the next, and even using part of the night to quarry out the heavy pieces of rock. At the end of the second day they went to the village on the Upper Bar and weighed their profits, which amounted to fourteen pounds! They started again the third morning under pretence of hunting, but were suspected and followed by the other diggers, who came upon them just as they commenced work. The news rapidly spread, and there was soon a large number of men on the spot, some of whom obtained several pounds per day, at the start. The gulch had been well dug up for the large lumps, but there was still great wealth in the earth and sand, and several operators only waited for the wet season to work it in a systematic manner. The next day Col. Lyons, Dr. Gillette and myself set out on a visit to the scene of these rich discoveries. Climbing up the rocky bottom of the gulch, as by a staircase, for four miles, we found nearly every part of it dug up and turned over by the picks of the miners. Deep holes, sunk between the solid strata or into the precipitous sides of the mountains, showed where veins of the metal had been struck and followed as long as they yielded lumps large enough to pay for the labor. The loose earth, which they had excavated, was full of fine gold, and only needed washing out. A number of Sonorians were engaged in dry washing this refuse sand--a work which requires no little skill, and would soon kill any other men than these lank and skinny Arabs of the West. Their mode of work is as follows:--Gathering the loose dry sand in bowls, they raise it to their heads and slowly pour it upon a blanket spread at their feet. Repeating this several times, and throwing out the worthless pieces of rock, they reduce the dust to about half its bulk; then, balancing the bowl on one hand, by a quick, dexterous motion of the other they cause it to revolve, at the same time throwing its contents into the air and catching them as they fall. In this manner everything is finally winnowed away except the heavier grains of sand mixed with gold, which is carefully separated by the breath. It is a laborious occupation, and one which, fortunately, the American diggers have not attempted. This breathing the fine dust
