When the camp is located where there is no material for a bough-bed,
each girl can carry with her a bag three feet wide and six and one-half
feet long, made of strong cloth, ticking, soft khaki, or like material,
to be filled with leaves, grass, or other browse found on or near the
camp-grounds. Such a mattress made up with poncho and blankets is very
satisfactory, but it must be well filled, so that when you lie on the
mattress it will not mash flat and hard.
