A quickly made bed for a camp is shown in the illustration. The corner posts consist of four forked stakes driven in the earth so that the crotches are on a level and about 1 ft. from the ground. Poles are laid in the crotches, lengthwise of the bed, and canvas covering double-lapped over them. If desired, the canvas can be stitched along the inside of the poles. - Contributed by Thomas Simpson, Pawtucker, R I
