Body. 1 Extract of Beef Box (about 3 1/2 in. deep, 7 1/4 in wide, 9 in. long).
One Shelf. 1 Piece 3/8 in. thick, width and length to fit inside the box.
Remove the cover and one end. Make a cover 11 inches long from a portion of another box. Five and three quarter inches from one end on the center line of the cover will be the center for the hole which is to be cut that the clock dial may be seen. With a pair of dividers inscribe a circle to suit the size of the face of the clock and bore a hole, about 1/2 inch in diameter, inside the circle. The outer edge of the hole should be on the circle line. Insert the keyhole-saw in the small opening and cut on the line of the circle completely around, and sandpaper true and smooth the edges after the circular piece is removed. Eight and a half inches from the same end and on the center line of the cover will be the radius point for the arch. Set the dividers 2 1/2 inches open and describe the arch line, which is slightly less than a semicircle. Mark the length of the box on each side edge of the cover, and cut from that point to the arch line. With the keyhole-saw cut around on the arch line. Fit the shelf in the box at the proper height to suit the clock, which will stand upon the shelf inside the clock case. Nail on the cover with the open end of the clock case at the top. Set the clock upon the shelf through the open top end of the case. The face of the clock case can be made quite a pleasing feature by the use of an appropriate design.
