The wood required will be two strips of yellow deal, bass-wood, or sycamore, 1 ft. 4 ins. long, 1 1/2 in. wide, and 1 in. thick, and two 10 ins. long, of the same width and thickness.

In this exercise the tenons are all made on the short sides, and the mortices in the long sides. It is usually more convenient to mortise in large than in small pieces of wood, as they can be secured better. The rebate round the inner edge at the back should be made after cutting the mortice and tenon from the solid wood, but before finally jointing up.
