It is difficult for the expert to draw the line between these two classes, and parents and teachers are loth to admit that the morons are defective. This problem can best be solved by the establishment of special classes in the public schools for all who lag more than one year behind. If for no other reason, the normal children should be relieved of the drag of these backward pupils. The special classes will become the clearing houses. The training should be largely manual and industrial and as practical as possible. As the number of classes in any school district increases, the classification will sift out those who are merely backward and a little coaching and special attention will return them to the grades. The others--the morons--will remain and as long as they are not dangerous to society (sexually or otherwise) they may live at home and attend the special classes. As they grow older they will be transferred to proper custodial institutions. In the city districts, where there are many classes, this will occur between twelve and sixteen years of age. In the country districts it will occur earlier. These institutions will be the training schools and will form the center for the training and care of the other two groups, i. e., the imbeciles and idiots. Branching out from the training schools should be colonies (unless the parent institution is on a very large tract of ground, which is most advisable). These colonies, or groups of comparatively small buildings, should be of two classes. For the imbeciles, simple buildings costing from two to four hundred dollars per inmate. The units might well be one hundred. A unit providing four dormitories, bath house, dining-halls, employees' buildings, pump house, water tank, sewage disposal, laundry, stables and farm buildings can be built within the above figures providing the buildings are of simple construction and one story. This has been done at Vineland by having the larger imbecile and moron boys make the cement blocks of which the buildings are constructed. For the idiots the construction can be much the same. Larger porches facing the south and more toilet fixtures will be necessary, and so add a little to the cost. The colony should be located on rough uncleared land--preferable forestry land. Here these unskilled fellows find happy and useful occupation, waste humanity taking waste land and thus not only contributing toward their own support, but also making over land that would otherwise be useless. One reason for building inexpensive buildings is that having cleared a large tract--say 1,000 acres--the workers can be moved to another waste tract and by brushing, clearing of rocks, draining and what not, increase its value sufficiently to keep on moving indefinitely.
