rude and incomplete enough. In all the gulches, at depths varying from six to fifty feet, is a bed-rock of the same general conformation as the surface. Usually this is granite; but sometimes before reaching the primitive rock two or three strata of pipe-clay—the later beds of the stream, upon which frequently lies a deposit of gold—are passed. Upon the bed-rock is a deposit, from three to four feet in depth, of gravel and boulders, in which the gold is hidden. This is called by the miners "pay-dirt," and to remove it to the surface and wash it is the end of mining. It is an expensive and laborious process indeed. The water has first to be controlled; and in mines of not too great depth this is done by a drain ditch along the bed-rock, commenced many claims below. In this all the claim-holders are interested, and all contribute their quota of the labor and expense of digging it. The district laws permit every person to run such a drain through all the claims below his own, and force every man to contribute alike towards its construction, on pain of not being allowed to use the water, even though it flows through his own land. The water controlled, the rest is mere physical labor, which only bones and sinews of iron can endure. In the shallow diggings the superincumbent earth above the pay-dirt is removed, and the process is called "stripping." In deep diggings a shaft is sunk to the bed-rock, and tunnels are run in every direction,—and this is called "drifting." The roof is supported by strong piles, but these supports too frequently give way, and hurry the poor miners to untimely deaths. The pay-dirt, in whichever way obtained, is then shovelled into the sluice-boxes,—a series of long troughs, set at the proper angle to prevent the gold from washing past, or the dirt from settling to the bottom. Managed with the skill which experience has taught, the constant stream of water carries over the sand, while the gold, being seven times heavier, sinks to the bottom, and is caught by cross-bars called "riffles," placed there for the purpose. In the lower boxes is frequently placed quicksilver, with which the lighter particles amalgamate. During the washings the larger stones and boulders are removed by a fork. These boxes, after a successful day's work, are a pleasant sight to see, all brilliant with gold and black sand and magnetic iron. All is gold that glitters. The heavy sand and iron are separated by a more careful washing by hand and by the magnet. Of course, all this system is very rude and imperfect,—so much so, that it has been found profitable in California to wash over the same earth nine times.
The gold-dust thus obtained is the only circulating medium in the Territory, and is the standard of trade. Treasury notes and coin are articles of merchandise. Everybody who has gold has also his little buckskin pouch to hold it. Every store has its scales, and in these is weighed out the fixed amount for all purchases according to Troy weight. An ounce is valued at eighteen dollars, a pennyweight at ninety cents, and so on. It is amusing to notice how the friction of the scales is made by some men—particularly the Jews, whose name is legion—to work them no loss. In weighing in, the scale-beam bows most deferentially to the gold side; but in weighing out, it makes profound obeisance to the weights. The same cupidity has given rise to two new terms in the miners' glossary,—trade dust and bankable dust. Bankable dust means simply gold, pure and undefiled. Trade dust is gold with a plentiful sprinkling of black sand, and is of three grades, described very clearly by the terms good, fair, and dirty. The trader, in receiving our money, complains if it does not approximate what is bankable, but in paying us his money pours out a combination in which black sand is a predominating ingredient. Many merchants even keep a saucer of black sand in readiness to dilute their bankable gold to the utmost thinness it will bear.
As might be expected, the courts were hardly opened before grave questions arose as to the construction of contracts
