Body. 1 Grocery Packing Box (about 7 3/4 in. deep, 21 1/2 in-wide, 31 1/2 in. long). 2 Shoe-polish Boxes (about 55/8 in. deep, 7 1/2 in. wide, 97/8 in. long).
Shelves. 2 Pieces 1/2 in. thick, width equal to the inside depth of the box, length equal to the inside width of the box.
Corner Trim. 4 Strips 1/2 in- thick, 1 1/4 in. wide, length equal to the outside length of the large box. 4 Strips 1/2 in. thick, 1 3/4 in. wide, length equal to the outside length of the large box.
Vertical Facing Strips. 4 Strips 1/2 in. thick, 2 in. wide, length equal to the outside length of the large box.
Top Facing Strips. 2 Strips 1/2 in. thick, 2 in. wide, 1 in. longer than twice the outside length of the small box and the outside width of the large box combined. 4 Strips 1/2 in. thick, 2 in. wide, 1 in. longer than the outside width of the large box.
Make the legs as long as the outside length of the large box. Remove the covers. Fit and nail the shelves in place, making one compartment about 6 inches high, the other two being of equal height. The shelves may be fastened with 1 1/4 inch brads driven through the side and bottom of the box into the edges of the shelves. Turn the large box on its end on the floor, the large compartment being at the lower end. Place one of the small boxes on the floor against the side of the large box and nail them together. Do the same with the other small box at the other side of the large box. Nail the corner trim on the outer end of each small box, also two vertical facing strips on both the front and the rear on the side edge of the large box. Keep the inner edges of these strips even with the inside face of the side of the large box and their upper ends even with the outside face of the top end. Lay the long top facing strips, flat side down, across the front and rear edge of the stand and nail them. Keep their ends even with the outside face of the corner trim. Their outside edges are also to be even with the outside face of the corner trim and vertical facing strips. Two inches back from each end of these top facing strips make a saw-cut 1/4 inch deep and, with a chisel, cut away the top half of the strip at this point. Do the same with each end of all the short facing strips. Make two similar saw-cuts 2 inches apart across the top of the long strips, in line with both edges of the four vertical facing strips and cut away in like manner. Place all the short strips in place, the uncut side up, and fit their ends into the recesses cut in the long strips and nail them. These recesses are made and fit like those described for the Picture Frame, Illustration 72.
