The drawing shows the manner of con- struction. The main standards or supports are joined together by four cross-pieces or rails fastened in place with dowels or long wood screws. If screws are used procure round-headed ones. The braces are fitted in on the prop)er angles and fastened with screws. The two upper and longest cross- pieces are fastened to the edges of the stan- dards to make a space between for the sliding standards.

The sliding standards are joined at the
