Set of Sieves

“Close to the place where the dredge is emptied there ought to be a tub about 2 feet in diameter and 20 inches deep, provided with a set of sieves so arranged that the lowest sieve fits freel within the bottom of the tub, and the three remaining sieves fit freely within one another. Each sieve has a pair of iron handles through which the hand can pass easily, and the handles of the largest sieve are made long, so that the whole nest can be lifted without stooping or putting the arms into the water.” — Encyclopedia Britannica, 1893
