Such an arrangement is shown in Fig.

239.
As to the individual benches, those without high backs are to be preferred, not only because of their convenience when it is desired to work on large pieces, like table tops, and because the backs do not interfere with the light, but because it is easier for the teacher to look over the room to see that everything is in order.

If the equipment is kept complete, it is an easy matter to glance over all the benches and the general rack to see that everything is in place.
[Illustration: Fig.239.General Tool rack in a School Shop.] In general, there are two methods of keeping guard over tools, the open and the closed.

In the open method, everything is kept in sight so that empty places can be discovered readily.

This method is a convenient one, and, besides, the tools are always easily accessible.
In the closed method, the tools are kept in drawers and cases where they can be locked up.
