The instruction of deaf mutes in articulate speech has of late years attracted considerable attention in both Europe and America. In some of the European schools, in the Clark Institute at Northampton, Massachusetts, and in a few of our State institutions it is brought to great perfection. There are also special schools for this system of teaching in most of our large cities. The majority of pupils in these schools converse with ease, and understand readily what is said to them by means of the motion of the lips. The Clark Institute at Northampton, already referred to, under the conduct of Miss Harriet Rogers, is the largest and most widely known of the schools for this special method of instruction in this country. This is not a State institution, but one endowed by the munificence of a private gentleman, and consequently subject to none of the restrictions imposed on the public institutions. Of course, only the most promising pupils are sent there, and from these a careful selection is made, by which means the highest possible success is ensured. Some of the State institutions, however, burdened as they are with a large and unassorted mass of pupils, have made most encouraging progress in this direction. Of these, one of the most successful is the Illinois institution. In its last published report the correspondence between the principal and the parents of those pupils who have been taught by this method is given, showing the utmost satisfaction at the progress made and results attained.
