To make a setting board for butterflies and moths, choose a piece of wood about 1 in. thick; groove it down the centre, and bevel it off towards the sides, so that at the edges the wood is only 3 in. thick. On these bevelled faces entomological cork is glued, and a piece is also glued along the bottom of the groove. Rub down with emery paper when dry. The board may, if desired, be covered with white paper or with white paint. The width of the board and of the groove will depend upon the size of the insect for which it is required. It is usual to have boards of various widths, each long enough to take two or three specimens.
