My object was to appeal to the senses of the public by doing the thing in every town where practicable.

By this method I succeeded, where the other would have failed, but it by no means followed that I was unacquainted with the philosophy of my own plans, merely because I preferred the doing of the thing to the writing about it.

Believing, however, that the time has now arrived, and that the public mind is better prepared than it was then, I have thought I might venture to go a little more into detail, in order to remove some well founded objections, which, but for this reason, would not have existed.

The infant mind, like a tender plant, requires to be handled and dealt with carefully, for if it be forced and injudiciously treated during the first seven years of its existence, it will affect its whole constitution as long as it lives afterwards.
There are hundreds of persons who will not believe this, and those persons will employ mere boys and girls to teach infants.

Let them do so if they please; I simply protest against it, and merely give it as my opinion that it is highly improper to do so.
