"When will you go?"
"Now, right off. I want to bring back some things with me, and I'll be gone two or three days, but I won't lose no time."
Jeff was one of those men who do not require long to make up their minds, and whom, having reached a decision, nothing can turn aside from its execution. Ten minutes later he was hurrying toward Dawson City, forty miles or more distant.
Inasmuch as Tim McCabe had practical knowledge of placer mining, the three decided to improve the time while Jeff was absent in taking out some of the gold which he assured them was there.
As has been explained, this form of mining is of the crudest and cheapest nature. In winter, after sinking a shaft to bed-rock, tunnels are run in different directions, and the frozen dirt piled up until warm weather permits its washing out. The distance to bed-rock varies from four to twenty feet. The gold is found in dust, grains, and nuggets, the last varying from the size of a hickory-nut or larger to small grains of pure gold.
It quite often occurs that the bed-rock is seamy, with many small depressions. It is supposed that when the débris containing the original gold swept over this bed-rock, the great weight of the metal caused it to fall and lodge in the crevices, where it has lain for ages. Certain it is that the richest finds have been made in such places.
Having fixed upon the spot where the work should begin, Tim McCabe and the boys set to work to clear off the coarse gravel and stone from a patch of ground. At the end of several hours they had completed enough to begin operations. Tim dropped a few handfuls of the finer gravel or sand into his pan, which was a broad, shallow dish of sheet iron. Then water was dipped into the pan until it was full, when he whirled it swiftly about and up and down. This allowed the gold, on account of its greater specific gravity, to fall to the bottom, while the sand itself was floated off by the agitation. Tim had learned the knack of dipping the pan sideways, so as gradually to get rid of the worthless stuff, while the heavy yellow particles remained below.
The boys stood attentively watching the operation, which was carried on with such skill that by and by nothing was left in the bottom but the yellow and black particles. The latter were pulverized magnetic iron ore, which almost always accompanies the gold. Frank's and Roswell's eyes sparkled as they saw so much of the yellow particles, even though it looked almost as fine as the black sand.
