Nail on the strut, pressing the legs well up against the shoulders. Its
fellow on the other side of the legs is prepared in exactly the same
manner; and the second trestle is a duplicate of the first, with the
exception that the directions of the struts are reversed relatively to the
C piece, to preserve the symmetry--which, however, is not an important
point.

Back and Front.--The only operation to be performed on the front piece B
and the back G is the notching of them both on the inside faces at the
centre to take the ends of the bearer F, which performs the important
function of preventing any bending of the top planks. Lay the boards
together, top edges and ends level, and mark them at the same time. The
square is then used on the faces to give the limits for the notches, which
should be 1/4 inch deep and chiselled out carefully.
Draw cross lines with your square 3 inches from each end of both pieces, on
the inside, to show where the legs are to be. Bore holes in the boards for
the 3-inch screws which will hold them to the legs.
