We must not rely, however, entirely upon their _interest in it_.

All that we can expect from such an effort to interest them, as I have described and recommended, is to get a majority on our side, so that we may have only a small minority to deal with by other measures.

Still, _we must calculate on having this minority, and form our plans accordingly_, or we shall be greatly disappointed.

I shall, however, in another place, speak of this principle of interesting the pupils in our plans for the purpose of securing a majority in our favor, and explain the methods by which the minority is then to be governed.

I only mean here to say that, by such means, the teacher may easily interest a large proportion of the scholars in carrying his plans into effect, and that he must expect to be prepared with other measures for those who will not be governed by these.
You can not reasonably expect, however, that, immediately after having explained your plan, it will at once go into full and complete operation.
