Deaf children cannot be educated as other children, and in the schools there have to be employed special means of instruction. In the present chapter it is our purpose to consider these methods only as they represent, in a complete study of the provision of the state for the education of the deaf, the means which have been found necessary to employ to attain this end. From the beginning of organized instruction of the deaf in America a system of signs has been in use to a wide extent. At the time when the methods of instruction of the deaf were introduced into the first schools, the "sign language" was brought in as an essential part from France, where it had largely been formulated. Modified somewhat and considerably enlarged--and in conjunction with the manual alphabet, of Spanish origin--the system has taken its place as a recognized means of education and communication in the great number of the schools. The deaf themselves after passing from the doors of the schools have employed the sign language mainly in their intercourse with one another, and with most of them meetings and social affairs are conducted virtually entirely in this manner. Thus the sign language has for long been one of the vehicles--usually the chief vehicle--of communication among the deaf and their instructors. With the sign language for practical use goes the manual alphabet, or "finger-spelling," by which the several letters of the alphabet are represented on the hand, the two together really constituting the language.[546] The order of signs itself forms to an extent a universal language. It consists of gestures, bodily movements, mimic actions, pantomime, postures--and to carry a close shade of meaning, even the shrugging of shoulders, the raising of eyebrows and the expression of the face--all appealing graphically to the accustomed eye. The signs of which it is made up are partly natural, and partly arbitrary or conventional; and the whole system as now practiced has been codified, as it were, for experienced users. By the deaf it can be employed rapidly and with ease, and is readily and clearly understood. Many of them become such masters of this silent tongue that it may be used with grace, warmth and expressiveness.[547] RISE AND GROWTH OF THE ORAL MOVEMENT This system of signs, however, has not been looked upon with favor by all parties. The "sign language" is said to be a foreign language, known and understood by only a very small part of the population, standing as a great barrier to the acquisition of language used by people generally, and tending to make the deaf of a class apart or "clannish." In its place in the schools would be substituted what is known as the "oral method," and speech and lip-reading would be used as the means of instruction. It has been sought thus to give all the schools over to the oral method, and summarily to drive out the sign language.[548]
