principle, that an infant who has managed to speak one word, has to stop, and go in search of the next, and then to concentrate the powers of its mind upon it, before he can give it expression. But if the reader will repeat the operation to himself upon the _same word_, till he can read its explanation in the sentence without difficulty and without a pause; and then do the same with two, then with three, and so on, till he has completed the whole; he will be able to appreciate in some measure the importance of this exercise in training the young to such a command of language, as will enable them, on all known subjects, to deliver fluently, and in any variety of form, the precise shade of meaning which they wish to express. This of itself will be a great attainment by the pupil; but it is not all. The reader will also perceive what must be the necessary result of persevering in this exercise, during the time of a child's attendance at school, in training him to that calm self-possession,--that perfect command of the mind and the thoughts,--while engaged in speaking, which the frequent and gradually extended use of this exercise is so well calculated to afford. All the children of a school, without exception, may be exercised by its means, and upon the same paragraph; for while, by the paraphrasing of but one word in a clause, it is within the reach of the humblest intellect; yet, by the changes and transpositions necessary in more difficult passages, either to smooth asperities, or to avoid grammatical errors, it provides an extemporaneous exercise suited to the talents of the highest grade in any seminary.
