CHAPTER VIII.
TYPES OF WOODEN STRUCTURES.
The articles suitable to be made in wood with hand tools may for convenience be divided into four general classes: (1) Unjoined pieces; (2) board structures; (3) panel structures; (4) framed structures.

A few illustrations of each class are given below.
(1) SIMPLE OR UNJOINED PIECES Of these there are a number that are advantageous for the learning of tool processes; at the same time they give opportunity for expression in design, and when finished are of use.
Examples are: key-boards, chiseling-boards, bread-boards, sleeve-boards, ironing-boards, coat- and skirt-hangers, and gouged trays.

Some of these are so simple as to include hardly any process but planing, directions for which are given above, p.

72.
[Illustration: Fig.270.

Pen-Tray.] Where there is more than one process involved, the order of procedure is of importance.
