As this work is intended almost exclusively for beginners, much detail has been admitted, and many of the specific measures here proposed may perhaps be safely adopted where no others are established.

There may also, perhaps, be cases where teachers, whose schools are already in successful operation, may ingraft upon their own plans some things which are here proposed.

If they should attempt it, it must be done cautiously and gradually.

There is no other way by which they can be safely introduced, or even introduced at all.

This is a point of so much importance, that I must devote a paragraph to it before closing the chapter.
Let a teacher propose to his pupils, formally, from his desk, the plan of writing propositions, for example, as explained above, and procure his wrapper, and put it in its place, and what would be the result?
Why, not a single paper, probably, could he get, from one end of the week to the other.
