On top of them and in line with the inner face of the legs are the guides running between the front and back posts.

Or the runner and guide may be made of one piece properly rabbeted out.
[Illustration: Fig.295.Drawer Mechanism.] If there are two drawers, a double runner lies between, and is gained into the middles of the back rail and the stringer, and on it is a guide for both drawers, equal in width to the partition between the drawers.

The drawers should run easily in their proper places.

In order to insure this, the drawer should be slightly narrower than the opening which receives it.

A little French chalk, rubbed on the sides and runners, makes the running smoother.
