Ill: Footstool For Cement Floors
A clerk finding the cement floor of the office uncomfortably cold to the feet, devised a footstool in the following manner: A shallow box was procured, and four small truck casters were fastened to the bottom. A piece of carpet was laid on the inside of the bottom and some old newspapers placed on top of it. When seated at the desk, he placed his feet inside the box on the papers. The casters elevated the box from the cement, just high enough to avoid dampness and cold, and permitted an easy change of position. - Contributed by L. Alberta Norrell, Gainesville, Ga.
