Attendance at continuation schools is now compulsory on boys and girls for three years after leaving the elementary school, where they have had eight years steady education. They must attend from four to six hours weekly; instruction is free, and is given in the evening, when the working day is over. Certain classes of the community are free, but about 30,000 students attend these schools in Berlin. The subjects taught are too many to enumerate. They comprise modern languages, history, law, painting, music, mathematics, and various domestic arts, such as ironing and cooking. More boys than girls attend these schools, as girls are more easily exempt. It is presumably not considered so necessary for them as for their brothers to continue their education after the age of fourteen. One of the most interesting experiments being made in Germany at present is the "open air" school, established for sickly children during the summer months. The first one was set up by the city of Charlottenberg at the suggestion of their _Schulrat_ and their school doctor, and it is now being imitated in other parts of Germany. From Charlottenberg the electric cars take you right into the pine forest, far beyond the last houses of the growing city. The soil here is loose and sandy, and the air in summer so soft that it wants strength and freshness. But as far out as this it is pure, and the medical men must deem it healing, for they have set up three separate ventures close together amongst the pine trees. One belongs to the Society of the Red Cross, and here sick and consumptive women come with their children for the day, and are waited on by the Red Cross sisters. We saw some of them lying about on reclining chairs, and some, less sickly, were playing croquet. The second establishment is for children who are not able to do any lessons, children who have been weeded out by the school doctor because they are backward and sickly. There are a hundred and forty children in this school, and there is a crêche with twenty beds attached to it for babies and very young children. One airy room with two rows of neat beds was for rickety children. The third and largest of the settlements was the _Waldschule_, open every day, Sundays included, from the end of April to the middle of October, and educating two hundred and forty delicate children chosen from the elementary schools of Charlottenberg. We arrived there just as the children were going to sit down to their afternoon meal of bread and milk, and each child was fetching its own mug hanging on a numbered hook. The meals in fine weather are taken at long tables in the open air. When it rains they are served in big shelters closed on three sides. Dotted about the forest there were mushroom-shaped shelters with seats and tables beneath them, sufficient cover in slight showers; and there were well lighted, well aired class-rooms, where the children are taught for twenty-five minutes at a time.
