The officers of the league can see that the instructions on the certificate are understood and carried out. Many individuals are careless and must be constantly watched to see that they do not neglect important precautions. Probably the most difficult thing the league will have to do will be to induce its members to keep their windows open and let fresh air and sunlight into their rooms. The officers and committees of the league should urge the members to keep the windows of their rooms open, especially at night, and to avoid overcrowding their sleeping rooms. Whenever a dark room or closed window which should be open is found, the danger should be pointed out, and the member urged to correct it. The practice of sleeping with the head and face covered is so deeply rooted in the negro race that it seems almost hopeless to attempt to eradicate it in the present generation. It is a most pernicious habit. The dangers of the practice should be pointed out, and the members urged to abandon it. Children should not be allowed to contract the habit. The careless spitting of consumptives in their homes is a practice dangerous to others. The careless at times spit on the floor, the walls, the hearth of the open fire, or on the stove if one is used. The sputum of the consumptive dries and is carried into the air as dust. This is drawn into the lungs when one breathes. The dangers of this should be emphasized, and the proper way to dispose of sputum shown. The consumptive should catch all of his sputum and burn it. There are cheap cups made of paper that can be had at small cost, and these should be used to spit in, and when they are full they should be burned. The better cups have covers to them, so that the flies can not get at the sputum. While consumption is a dangerous disease, the careful consumptive is not dangerous to live with. The careless consumptive, however, is dangerous to live with and a menace to those around him. The minister and the officers of the leagues should consult frequently with the health officer of their community. Working together they can accomplish much more than by working alone.
