Tho purpose pur-pose of the burlap Is to bring the condensed con-densed stcnm In contact with tho air current. As tho air passes over the radiator radi-ator It Is heated nnd its capacity to pick up molsturo Is greatly Increased." It then strikes tho saturated curtains and absorbs ab-sorbs tho moisture.
