225. The subjects next to be considered in the choice of material for instruction are poetry and natural history, great care being taken not to disregard the necessary sequence. The time for fables and stories should not be curtailed; it is important to make sure that boys do not lose the taste for them too early. The easiest and safest facts of zoölogy will have been presented already in connection with the picture-books of childhood. The right moment for introducing the elements of botany has arrived when the boy is collecting plants. Foreign languages would be assigned the lowest place, if particular circumstances did not in many cases lend them a special importance. The ancient classical languages, at any rate, form to such an extent the basis of the study of theology, of jurisprudence, and of medicine, they are so necessary to all higher scholarship, that they will always constitute the fundamental branches of instruction in academic preparatory schools.
It is obvious, however, that the extent of instruction depends too much on external conditions of rank and means to permit a definite prescription of instruction-material for all cases. Far less dependent is the development of many-sided interest in its relation to branches of study. If the limits set to the latter are narrow, it is still the business of instruction to secure an approximation to many-sided culture; while under highly favorable circumstances the very abundance of educational help must put the teacher on his guard against losing sight of the real aim of instruction.
226. Frequently the burden of necessary and useful studies is made excessively heavy, a fact which the members of the teaching profession try to conceal from themselves, but which attracts the attention of outsiders. A few hours of gymnastics do not sufficiently counteract such evil effects. As an offset we have at best the prevention of the vices of idleness. From every point of view, for the mere reason that this matter calls for special attention and that the method of procedure has to be determined in accordance with the results of observation, the home must do its part toward relieving that natural strain which even good instruction exerts--and the school must not encroach on the time necessary for that purpose. In extreme cases, to be sure, it may be expressly demanded that the school engage the whole of a boy’s time. But, as a rule, outside school-work should take up, not the largest, but, on the contrary, the smallest amount of time possible. How the remaining hours are to be employed is for parents and guardians to decide according to individual needs, ascertained by observation; and it is on them that the responsibility for the consequences rests.
