Very cheap but useful and attractive book shelves are shown in the accompanying drawing. The vertical strips, A, may be 3/4 in. by 2 in. and are screwed to four shelves, B, each cut to the shape of a quarter circle. The screws are all countersunk and as the heads all come on the side next to the wall, they do not show. The design might be varied somewhat to suit the fancy of the builder, although the appearance of the shelves constructed as shown is very pleasing, especially so if the workmanship is good and the wood carefully stained and varnished. The total cost of construction was less than 75 cents.
