But although I contest the alleged general influence of the life of large towns and of modern civilisation upon the morality and the sexual activities of children, I admit at once that peculiar conditions of place and time may exert a great influence in these respects. Frequently, no detailed analysis of these conditions is possible; but sometimes such an analysis can be effected. Only by the assumption that these special influences exist can we understand how it is that such marked differences exist at different times in the same place. I know certain schools in Berlin in which masturbation, and even mutual masturbation, are widely diffused; and I know others regarding which in this respect no unfavourable reports can be made. I know, indeed, of schools about which I have received from former pupils, persons whose trustworthiness I have absolutely no reason to doubt, reports which prove that a remarkably high level of sexual morality must have existed in these schools. On the other hand, ex-pupils of other schools, attended by boys of very various classes of the population, have informed me that at these schools there was hardly a boy who did not masturbate. It is not always possible to ascertain the causes of such differences. One child, perhaps, may corrupt an entire class. But I believe also that the influence of the schoolmasters, and especially that of the headmaster, may be of enormous importance in this respect. Similar differences exist in the country. It is even believed by some that there are differences between the Catholic and Protestant inhabitants of the rural districts. How extensive may be the differences even within a comparatively small area, is shown by an example, which I will quote, from C. Wagner.[74] One of the districts studied by him was the Province of Jagst in Wuertemberg, and he reports that there is a striking difference between the Alt-Wuertemberg and the Franconian districts. The report states that in the former district the greater number of parents appear to recognise it as their sacred duty to bring up their children properly and to watch over their development. Moral depravity could not be said to be general among the children of this region. Very different was it in the Franconian districts, in which not only were the children cared for much less perfectly, but in which also "the children saw and heard much too early things which impair or destroy the innocence and purity of the heart." We are told that shamelessness in the satisfaction of natural needs was general; some cases of self-abuse were reported; and obscene and lascivious conversation was common. The causes assigned for this in the report are: overcrowding in the dwellings, there being in some cases but a single bed for children of school age of different sexes; also that children had been present when cattle were performing the sexual act. Often in the country we are told that children have been corrupted by grown
