A very cheap but attractive book trough is shown in the accompanying photograph. This piece of mission furniture will be found useful in the home or office and can be made by anyone who has a slight knowledge of tools. The material should be either oak or chestnut, which can be secured from the planing mill dressed and sandpapered ready to cut the tenons and mortises. The stock needed will be as follows:

• 2 ends, 7/8 in. by 10 in. by 31 in., S-2-S.
• 1 shelf, 7/8 in. by 10 in. by 35 in., S-1-S.
• 2 trough pieces, 7/8 in. by 4 in. by 35 in., S-2-S.
• 8 keys, 5/8 in. by 5/8 in. by 3 in.

The two end pieces should be made first with the top corners rounded off and the lower end, which is of simple design, can be cut out with a bracket saw and smoothed with a wood rasp. The mortises should then be laid out according to the sketch and cut, by first boring 3/4-in. holes and finishing with a chisel, being careful to keep all edges clean and free from slivers.

The shelf can now be made by cutting a double-key tenon at each end to fit the end pieces. The space between the two tenons at each end can be cut out with a bracket saw and finished with a rasp. The key holes should be mortised as shown in the sketch. The trough pieces are made in a similar manner, care being taken to have all tenons and mortises perfectly square and a good fit, so the trough when assembled will have a neat and workmanlike appearance. The trough can be finished in any one of the many mission finishes which are supplied by the trade for this purpose.
