It has been suggested, in some of the public prints, that it should be the business of the superintendent of common schools to select text-books for the common schools in the state of New-York. It is questionable whether any single man could be found, to whom it would be safe to trust this important concern. DE WITT CLINTON himself, were he now living, would be unequal to the work, unless he were to qualify himself for it by an attention to the subject, such as he never gave. He, in conjunction with other distinguished literary men, recommended 'Bartlett's National School Manual,' a work containing many good things, but exceedingly defective as a whole. Like Pharaoh's lean kine, it is calculated to devour all other school-books, but after having done so, it would be a meagre skeleton still. The truth is, that a great majority of the most distinguished literary men in the country have devoted so little attention to school-literature, that on their recommendation of school-books but little reliance can be placed. But such ought not to be the case; for the subject is too important to be delivered over to less competent hands. A systematic arrangement and vigilant inspection of schools, stands intimately connected with their prosperity. They are a complicated concern, and like all such concerns, they require great and systematic attention. School-houses must be provided, fitted up with neatness and convenience, and worthy of the names of temples of science. It is disgraceful to science, to have mean and incommodious school-houses, in the midst of commodious or splendid dwelling-houses. They should be well lighted, have convenient benches and desks, and at the proper season, be easily and comfortably warmed. Every teacher knows how important these things are to the successful prosecution of the business of a school. If the school-room be hung round with maps and charts, and scientific diagrams, it will be so much the better. According to the laws of association by which the course of thought in the human mind is regulated, these things will take a strong hold of the susceptible minds of children, awaken a scientific curiosity, and divert them from their play to the proper business of the school-room, as well as afford valuable aids to the teacher in the business of instruction.
