In recommending the above Text-books, the Superintendent says: "They have been selected with a view to economy, as well as for their intrinsic value. Already extensively introduced in the State, an entire substitution of them can be effected in a short time, and at a very small outlay to the people." He inquires: "But can we unite upon them as Class-books? I answer, WE CAN, if we but sacrifice personal predilections upon the altar of public good; and when so much is at stake, let mutual concession be invoked, and personal preferences yield to that spirit that ever animates the bosom of the Patriot and Philanthropist."
