all physical senses. In the world of the blind child eyesight plays no part, and so the other senses are made to do double duty, and the extent to which these may be cultivated is limited only by the mentality of the child, its early training and environment.
I think hearing is the first sense to be cultivated, both in the infant and the adult suddenly deprived of eyesight. Through its ears, the child recognizes voices, detects different footfalls, is enabled to measure distance with a fair degree of accuracy, and can form a very clear idea as to the shape and dimensions of a room. All this information is conveyed to the normal child through the eyes. Dr. Illingworth, a noted educator of the blind in England, says: "Of course, there is no doubt that blindness tends to a higher and more perfect development of the sense of hearing, even in the uneducated, on the same principle that Nature almost always comes to the aid of her children in providing protective agencies of one kind or another, even in the very lowest organisms, and, naturally, for those who are blind, the sense of hearing is the first to fall back upon for this purpose. Thus it becomes more highly developed, because there is more frequent call upon, and exercise of, that sense." Another writer has said, "but a distinction should be made between sensitiveness and an ability to use the sense, between native sensory capacity of the sense organ, and the acquired ability to use that capacity."
The second sense to be developed in the blind child is that of touch, and this development begins at a very early date, supplementing the sense of hearing. Long before the child is old enough to read, its fingers have become its eyes, and each of the ten fingers carries its quota of information to the active brain, the amount and quality of this information increasing with the mental development. In addition to the fingers, the nerves of the face and those of the feet contribute their share of information. The child learns to detect differences in climatic condition by the feel of the air on its face. I have often heard very young blind children exclaim, "It feels like rain! It feels like a nice day! The air feels heavy! The wind feels soft! The wind is rough today!" The nerves of the feet contribute their share of helpful knowledge, calling attention to differences in the ground often unnoticed by the eye, telling whether the path is smooth or rough, grass-grown or rock-strewn. The auditory and pedal nerves are mutually helpful, the ear recording and classifying the sounds made by the feet, often guiding them aright by recalling certain peculiarities of sound--whether the ground is hollow, whether the sidewalk is of board or cement, and whether there is a depression here or a raised place there. I often wonder how deaf-blind people walk as well as they do, when they can not hear their footfalls. I find walking much more difficult when on a crowded thoroughfare, or when passing a planing mill or boiler factory.
The last of the trio of senses whose development compensates in large measure for the want of eyesight, is that of smell. Through this sense, the child comes very close to the heart of Nature. Of course, the ear is charmed by the song of birds, the hum of insects, the murmur of wind in the trees, or the sound of mighty waters. Through the finger-tips, he learns the shape and size of each flower and shrub and tree, traces the delicate pattern of ferns, notes wonderful rock formations, and finds the first blade of tender grass coaxed to the surface by the warmth of the Spring sunshine. But all this does not bring him the keen pleasure he experiences when he inhales the fragrance of the rose, the perfume of flowers with the dew still upon them, the smell of the freshly turned earth, the newly cut grass, or the blossom laden trees. In the case of Helen Keller, the olfactory nerves have been cultivated to a very high degree, and through this sense she is often able to recognize her friends. A little blind boy once told me that each member of his family had a distinct odor, by which he could tell things worn by them, or books they had handled. Laura Bridgeman is said to have selected the laundry of the pupils in her school by this unusual process. I frequently astonish my friends by telling them when I pass a drug store or hospital, a grocery, a confectioner's, or drygoods store, a paint shop, a florist's stand, or a livery stable. I do not think the blind have a keener sense of taste than
