3994. Life-Belts.—An excellent and cheap life-belt, for persons proceeding to sea, bathing in dangerous places, or learning to swim, may be thus made:—
3995. Take a yard and three-quarters of strong jean, double and divide it into nine compartments. Let there be a space of two inches after each third compartment.
3996. Fill the compartments with very fine cuttings of cork, which may be made by cutting up old corks, or (still better) purchased at the cork-cutters.
3997. Work eyelet-holes at the bottom of each compartment to let the water drain out.
3998. Attach a neck-band and waist strings of stout boot-web, and sew them on strongly.
