By this alteration the narrow channel was considerably enlarged, and a mass of sand and gravel carried off by the force of the torrent. Early in the morning after this took place, he (Mr. Marshall) was walking along the left bank of the stream, when he perceived something which he at first took for a piece of opal--a clear transparent stone, very common here--glittering on one of the spots laid bare by the sudden crumbling away of the bank. He paid no attention to this; but while he was giving directions to the workmen, having observed several similar glittering fragments, his curiosity was so far excited, that he stooped down and picked one of them up. 'Do you know,' said Mr. Marshall to me, 'I positively debated within myself two or three times whether I should take the trouble to bend my back to pick up one of the pieces, and had decided on not doing so, when, further on, another glittering morsel caught my eye--the largest of the pieces now before you. I condescended to pick it up, and to my astonishment found that it was a thin scale of what appears to be pure gold.' He then gathered some twenty or thirty similar pieces, which on examination convinced him that his suppositions were right. His first impression was, that this gold had been lost or buried there by some early Indian tribe--perhaps some of those mysterious inhabitants of the West, of whom we have no account, but who dwelt on this continent centuries ago, and built those cities and temples, the ruins of which are scattered about these solitary wilds. On proceeding, however, to examine the neighboring soil, he discovered that it was more or less auriferous. This at once decided him. He mounted his horse, and rode down to me as fast as it would carry him, with the news. "At the conclusion of Mr. Marshall's account," continued Captain Sutter, "and when I had convinced myself, from the specimens he had brought with him, that it was not exaggerated, I felt as much excited as himself. I eagerly inquired if he had shown the gold to the work people at the mill, and was glad to hear that he had not spoken to a single person about it. We agreed," said the Captain, smiling, "not to mention the circumstance to any one, and arranged to set off early the next day for the mill. On our arrival, just before sundown, we poked the sand about in various places, and before long succeeded in collecting between us, more than an ounce of gold, mixed up with a good deal of sand. I stayed at Mr. Marshall's that night, and the next day we proceeded some little distance up the South Fork, and found that gold existed along the whole course, not only in the bed of the main stream, where the water had subsided, but in every little dried-up creek and ravine. Indeed, I think it is more plentiful in these latter places, for I myself, with nothing more than a small knife, picked out from a dry gorge, a little way up the mountain, a solid lump of gold which weighed nearly an ounce and a half.
