The accompanying drawings show a method of constructing a strong oval top wooden box. The sides, ends, and bottom should be of wood about |in. thick, jointed together as at Figs. 1, 4, and 5. The top of the lid may be formed of two {-in. boards bent and glued together and nailed to the end pieces (see Fig. 2); or strips i in. by about 2 1/2 in. wide, jointed and glued together, may be used (see Fig. 3). The principal dimensions are given in the illustrations. Two or three coats of paint will be more serviceable than a covering. In the illustrations, Fig. 1 shows a front elevation: Fig. 2, an end elevation; Fig. 3, an alternate method of forming the lid; Fig. 4, a general view of the box; and Fig. 5, the method of joining the side to the front.
