Children have to attend school from the age of six and to stay till they are fourteen; and in their school years they are not allowed to work at a trade without permission. They do not learn foreign languages, but they are thoroughly grounded in German, and they receive religious instruction. Of course, they learn history, geography, and arithmetic. In the new schools every child is obliged to have a warm bath every week, but it is not part of a teacher's duties to superintend it. Probably the women who clean the school buildings do so. In the old schools, where there are no bathrooms, the children are given tickets for the public bathing establishments. The State does not supply free food, but there are philanthropic societies that supply those children who need it with a breakfast of bread and milk in winter. Everyone connected with German schools says that no child would apply for this if his parents were not destitute, and one teacher told me a story of the headmaster's boy being found, to his father's horror and indignation, seated with the starving children and sharing their free lunch. He had brought his own lunch with him, but it was his first week at school, and he thought that a dispensation of bread and milk in the middle of the morning was part of the curriculum. School books are supplied to children too poor to buy them, and it seems that no trouble is given by applications for this kind of relief by people not entitled to it. Gymnastics are compulsory for both boys and girls in the lower classes, and choral singing is taught in every school. Teachers must all be qualified to accompany singing on the violin. Most of the elementary schools in Prussia are free. Some few charge sixpence a month. A child can even have free teaching in its own home if it is able to receive instruction, but not to attend school. Medical inspection is rigorously carried out in German elementary schools. The doctor not only watches the general health of the school, but he registers the height, weight, carriage, state of nourishment, and vaccination marks of each child on admission; the condition of the eyes and ears and any marked constitutional tendency he can discover. Every child is examined once a month, when necessary once a fortnight. In this way weak or wanting children are weeded out, and removed to other surroundings, the short-sighted and the deaf are given places in the schoolroom to suit them. The system protects the child and helps the teacher, and has had the best results since it was introduced into Prussia in 1888.
