American named Marshall, a sort of millwright, to do this work for
him, but Marshall afterward claimed that in the matter of the
saw-mill they were copartners. At all events, Marshall and the
family of Mr. Wimmer were living at Coloma, where the pine-trees
afforded the best material for lumber. He had under him four white
men, Mormons, who had been discharged from Cooke's battalion, and
some Indians. These were engaged in hewing logs, building a
mill-dam, and putting up a saw-mill. Marshall, as the architect,
had made the "tub-wheel," and had set it in motion, and had also
furnished some of the rude parts of machinery necessary for an
ordinary up-and-down saw-mill.

Labor was very scarce, expensive, and had to be economized. The
mill was built over a dry channel of the river which was calculated
to be the tail-race. After arranging his head-race, dam and
tub-wheel, he let on the water to test the goodness of his
machinery. It worked very well until it was found that the
tail-race did not carry off the water fast enough, so he put his
men to work in a rude way to clear out the tail-race. They
scratched a kind of ditch down the middle of the dry channel,
throwing the coarser stones to one side; then, letting on the water
again, it would run with velocity down the channel, washing away
the dirt, thus saving labor. This course of action was repeated
several times, acting exactly like the long Tom afterward resorted
to by the miners. As Marshall himself was working in this ditch,
he observed particles of yellow metal which he gathered up in his
hand, when it seemed to have suddenly flashed across his mind that
it was gold. After picking up about an ounce, he hurried down to
the fort to report to Captain Sutter his discovery. Captain Sutter
himself related to me Marshall's account, saying that, as he sat in
