Olive-Press. In order to obtain the olive oil, the olives are first bruised in a rough trough, under a millstone, rolling perpendicularly over them; and when sufficiently mashed, put into the maye, or trough, m, of an olive-pres, where aa are the upright beams, or cheeks; b, the female, and c, the male screw; f, the board on which the screw presses; g, a cubical piece of wood, called a block; b, the peel, a circular board, to be put under the block. By turning the screw, all the liquor is pressed out of the mashed olives, and is called virgin-oil; after which, hot water being poured upon the remainder in the press, a coarser oil is obtained. Olive-oil keeps only about a year, after which it degenerates.

OLIVE Colour, a yellow mingled with black.
