Throughout the entire country at the same hour the sons of France shall pay respect to the spirit of their nation and shall pay tribute to the heroism of those who are pouring out their blood for liberty, justice, and human right. The words of the teachers on this occasion should be simple and to the point. They should be adapted to the age of their hearers, some of whom are children, some youths.

He should prefer these supreme models of action to the vain repetition of phrases, in order to make a fit impression on the minds of the children. A vivid recollection of this first school hour ought to remain imprinted forever in the spirit of the pupil, who is the citizen of to-morrow. The teacher who has known how to make this impression will remain worthy of the confidence of the republic.

The following excerpts are extremely suggestive of special opportunities and obligations for teachers in school service:
