The shelves are notched at the ends, so that their back faces shall be
flush with the board side of the frame.

Fix the corners with the screws, and plane off the projecting angles of the
uprights.

When putting on the boards, start at the back of the frame. Plane down the
groove edge of the first board until the groove is out of the board, and
apply the board with 1-1/2 inches projecting beyond the frame. Leave a
little spare at each end of every board, and when the side is covered run a
tenon-saw across both ends of all the boards close to the frame, and
finish up with the plane. This is quicker and makes a neater job than
cutting each board to size separately.

The Back (Fig. 20).--When laying out the frame for this, remember that
there is a bevel to be allowed for along the top, and that the height of
the frame at the front must be that of the back of a side frame. (See Fig.
21.) The boards should be cut off to the same slope.

Twenty-four boards should exactly cover the back. Cut the tongue neatly off
that last fixed, and glue it into the groove of the first board.

The Front.--The frame requires careful making. For details of corner
joints see Fig. 16. The 3-inch faces of the top and bottom bars are
vertical. The upper side of the top bar is planed off to the angle of the
slope. (Fig. 23.)
