In this country the organs of the special senses need great care. There are a great many blind people here, who have become blind because they have not understood how to take care of the eyes. The lids and the eyelashes are meant to protect the eyes and keep out dust, to prevent insects, etc., from getting into them. Nature has taken wonderful pains to protect our eyes, but we must do all we can to help her. She has prepared a fluid which washes the balls, but the outside of the eyes as well should be carefully washed once or twice a day, and wiped dry. We should be very particular to wipe them on a clean cloth. We should never use a towel that is used by any one who has any trouble with the eyes or who has any skin disease. The eyes should never be rubbed with the fingers. When any foreign matters, as specks of dust, or cinders, get into them, we should go at once to some skillful physician to have them removed. We should shade the eyes from the direct rays of the sun. If we walk out in the middle of the day, we should carry an umbrella or wear a broad hat. We should not strain the eyes, or use them when they are tired or when the light is bad. Alcohol is very bad for the eyes; it makes them weak. The eyes of a hard drinker become red and watery. Such a person may often become blind. Tobacco, too, causes dimness of sight, and has been known to produce blindness. Strange as it may seem, the ears are even more delicate than the eyes, and more readily injured; and when hurt, there is less that science can do for them. The outer ear only catches sound and turns it inward. The parts of the ear that really hear are deep in the head, where they can be well protected. The little canal leading into the ear secretes wax, which hinders insects from crawling in. Sometimes they do get in, despite the wax. In some parts of this country, there are leeches that get into the ear. When they do this they cause great pain and often produce deafness. We should never try to pick or lift anything of this sort out of the ear. The best way, when anything alive gets into the ear, is to pour in a little quantity of oil. This nearly always causes the creature which has gotten in to back out, in order to escape the oil. If, instead of coming out, it is drowned, it must be removed by some skillful physician.
