Teaching is found to be a very trying occupation on the general health, and particularly on the nervous system. Many girls break down or develop a chronic nervous trouble in a few years in the schoolroom. The combined work and worry prove too much for their strength; and not infrequently, also, the teacher who boards and carries a cold luncheon to school fails to secure the right kind of food. This is especially true in the rural schools. Farmers have enough to eat, but often the food suitable for men engaged in heavy manual labor is wholly unsuited for one who works with the brain and does not have a large amount of out-door exercise.

Nor do teachers always secure enough pure air. The air of schoolrooms is usually vitiated to such a degree that one on coming in from the out-door air can detect a foul odor. But the air of a room ceases to be fit to breathe long before an odor can be detected from its impurities.

These are some of the chief factors which are proving so fatal to the health of many of our teachers, and to interest and enthusiasm on the part of the teacher in his work. Both for the sake of his health and his work, every teacher should seek to control these three factors as far as possible. Strain and worry and wear of nerves can be greatly lessened by careful planning of work, by good organization and careful management, and by exercise of the will to prohibit worry over matters large or small when worry will not help solve them. The teacher can in some degree determine what food he will eat, even if it means a change of boarding-place. And surely every teacher can control the supply of fresh air for the schoolroom and his bedroom, and this is perhaps the most important of all.

d. Experience.—The young teacher, without experience, may from sheer embarrassment and lack of mastery fail to show the enthusiasm which he feels, for embarrassment of any kind and enthusiasm do not thrive well together. But if the teacher is really fundamentally interested in his teaching, the enthusiasm will soon come. And better a thousand times the young teacher who is earnestly fighting for freedom and mastery in the recitation, than the old teacher who has grown wearied of the routine and has made out of the recitation a machine process.

3. Well-mastered lessons

Probably the worst of all drawbacks to good recitations is poorly prepared lessons. One of the greatest criticisms to which our educational system is open is that teachers try to teach and pupils try to recite lessons which are badly or indifferently prepared by both. There is nothing more stupefying to the mind, or more fatal to interest in school work than the halting, stumbling, ineffective recitations heard in many schools. Teachers who try to teach lessons with which they are not thoroughly familiar are but blind leaders of the blind, and both they and their pupils are sure to fall into the ditch.

a. Preparation by the teacher.—The teacher is the key to the situation. If he himself lacks in preparation, he can neither lead nor compel his pupils to the preparation of their lessons. He sets the standard. A stream does not rise higher than its source.

The teacher's preparation has two different aspects: (1) The general fundamental knowledge of the subject as a whole obtained by previous study; and (2) the daily preparation by study, thought, or reading for the recitation.

In general it is safe to say that teachers enter upon their vocation without sufficient education. Our certificate requirements are low, and many enter upon teaching with little or no more schooling than that obtained in the schools where they begin teaching. Of course this is radically wrong, but it is the fault of our school system and not of the teacher. It behooves teachers entering upon their work with this scanty preparation to recognize their limitations, however, and to do their best to remedy them. Low grade of certificate, low standings in any branches, or the teacher's own consciousness of lack of mastery should be sufficient to send the sincere and earnest teacher to school again, even if this must be to summer schools instead of longer sessions. This sacrifice will not only pay abundantly in higher salary, but also in greater teaching power and in the sense of greater mastery and personal growth.

But no amount of preparation in a branch will relieve a teacher of the necessity of daily preparation for the recitation. Dr. Arnold expressed this thought when he said: "I prefer that my pupils shall drink from a running stream, rather than from a stagnant pool." In order that one may develop a line of thought easily it must be fresh in his mind; it is not enough that he has once known it well. One of the master teachers of our country, a university professor who is recognized as a great authority in his chosen subject, Latin, recently said to a group of Latin teachers: "I have taught Cicero for twenty years, until I know it by heart. But yet, every day, one hour before the time for my Cicero class, I go to my study and spend an hour with Cicero, just to get into the spirit of it. I would not dare to meet my class without this."
