For this clock-case and book-rack the construction should start with the two ends, which are identical. After trimming them to size, accurately mark out and cut the mortises for top and bottom boards. These are then to be tenoned on their ends to match and receive the square holes for the tight-ening-keys. Make the curved strips at top and bottom of pieces separate from backing. A rear edge of both the top and bottom pieces will have to be notched out to fit in the backing. (See end view.) Fit the two ends and shelves together, then nail on backing, after which place the intermediate shelf. Work up curved strips at top and bottom from heavier material than backing and secure in place with nails set in from behind. The two vertical pieces that form the sides of the clock-case are now in order, after which the face should be fitted.
