Century Dictionary and Cyclopedia
    • n riffle In mining, the lining of the bottom of a sluice, made of blocks or slats of wood, or stones, arranged in such a manner that chinks are left open between them. In these chinks more or less quicksilver is usually placed, and it is by the aid of this arrangement that the particles of gold, as they are carried downward by the current of water, are arrested and held fast. The whole arrangement at the bottom of the sluices is usually called the riffles. In the smaller gold-saving machines, formerly much used, as the cradle, the slats of wood nailed across the bottom for the purpose of detaining the gold are called riffle-bars or simply riffles.
    • n riffle A piece of plank placed transversely in, and fastened to the bottom of, a fish-ladder. The riffles do not extend from side to side, but only about two thirds across. If the first riffle is fastened on the right side of the box at right angles to its side, it will extend about 30 inches across the box; the next, about 4 feet above, will be fastened on the left side of the box; the next, about 4 feet above, on the right side; and so on alternately until the top is reached. The water passing into the top is caught by the riffles and turned right and left by them until it reaches the stream below. Riffles furnish the fish a resting-place in scaling a dam.
