Miss Keller's reading of the manual alphabet by her sense of touch seems to cause some perplexity. Even people who know her fairly well have written in the magazines about Miss Sullivan's "mysterious telegraphic communications" with her pupil. The manual alphabet is that in use among all educated deaf people. Most dictionaries contain an engraving of the manual letters. The deaf person with sight looks at the fingers of his companion, but it is also possible to feel them. Miss Keller puts her fingers lightly over the hand of one who is talking to her and gets the words as rapidly as they can be spelled. As she explains, she is not conscious of the single letters or of separate words. Miss Sullivan and others who live constantly with the deaf can spell very rapidly--fast enough to get a slow lecture, not fast enough to get every word of a rapid speaker. Anybody can learn the manual letters in a few minutes, use them slowly in a day, and in thirty days of constant use talk to Miss Keller or any other deaf person without realizing what his fingers are doing. If more people knew this, and the friends and relatives of deaf children learned the manual alphabet at once the deaf all over the world would be happier and better educated. Miss Keller reads by means of embossed print or the various kinds of braille. The ordinary embossed book is made with roman letters, both small letters and capitals. These letters are of simple, square, angular design. The small letters are about three-sixteenths of an inch high, and are raised from the page the thickness of the thumbnail. The books are large, about the size of a volume of an encyclopedia. Green's "Short History of the English People" is in six large volumes. The books are not heavy, because the leaves with the raised type do not lie close. The time that one of Miss Keller's friends realizes most strongly that she is blind is when he comes on her suddenly in the dark and hears the rustle of her fingers across the page. The most convenient print for the blind is braille, which has several variations, too many, indeed--English, American, New York Point. Miss Keller reads them all. Most educated blind people know several, but it would save trouble if, as Miss Keller suggests, English braille were universally adopted. The facsimile on page xv [omitted from etext] gives an idea of how the raised dots look. Each character (either a letter or a special braille contraction) is a combination made by varying in place and number points in six possible positions. Miss Keller has a braille writer on which she keeps notes and writes letters to her blind friends. There are six keys, and by pressing different combinations at a stroke (as one plays a chord on the piano) the operator makes a character at a time in a sheet of thick paper, and can write about half as rapidly as on a typewriter. Braille is especially useful in making single manuscript copies of books.
