If it is argued that I gained this knowledge through the ear, and not through the magnetic medium that I suppose to exist, I will add other experiences that will be more convincing to the reader.
In pursuing my business as itinerant book-seller for many years, I have frequently called at offices when their occupants were out, and on entering have often said to my guide, “Oh, there is no one here, let us go, and call again.” On the other hand I have often been conscious when entering a room that there was not only one mind but several minds present. If I should be asked to describe this consciousness, or mental recognition, I should not know what language to employ. These are some of the compensations which the blind receive for the great loss they have sustained. The sense of smell is ranked as the least important of all the senses, yet it is of great value to the blind. Through this avenue to the mind come many pleasurable sensations. By it we are aided in the selection of our food, in choosing ripe and healthful fruits, in detecting decomposition, dirt and filth, and in ascertaining much that eyes discover to those who have them. Without it flowers would have no attraction for us, and life would lack many of its pleasures. At the risk of being classed among dogs and vultures. I acknowledge that I am often guided by my olfactories in doing things that seem so very unaccountable to my friends.
In passing along the business streets my attention is continually attracted by the odors that issue from stores, shops, saloons, etc., and these peculiar smells often direct me to the very place I wish to find. From groceries come the odors of spices, fish, soaps, etc. From clothing and dry goods stores the smell of dye-stuffs. From drugs and medicines, the combined odor of many thousand volatile substances, such as perfumes, paints, and oils, asafaoetida, etc. From shoe stores comes the smell of leather; and from books and stationery the smell of printer’s ink. Hotels, saloons and liquor stores, emit that unmistakable odor of alcohol, the prince of poisons. To me the smell of alcohol, wines, etc., has always, since my earliest recollection, been grateful and fascinating; and had I cultivated an appetite for strong drink, it would be as difficult for me to pass a liquor saloon as for a man whose eyes are tempted by a magnificent display of mirrors and bottles. I have often been made aware of open cellar doors by a damp, musty smell that commonly proceeds from underground rooms, and have, I think, been saved from falling by this odd warning. I should have fallen, however, only a few days ago, into one of these yawning horrors had it not been for my ever watchful wife who was providentially near and called to me in time to save me from injury. Some workmen were laying a patch of side-walk on Main street, in the town in which I reside, and had opened a cellar-way near which some of them were at work, but did not warn me, doubtless because they did not see me, for workmen are always very kind to me.
