The royal statutes require that in every public secondary school in Sweden there shall be at least three hours a week of pedagogical gymnastics, arranged in daily half-hour periods when possible. In Stockholm the division into half-hour lessons is the most common one. Less frequently there are three periods of an hour each, and in a few cases a class meets twice for a half-hour and twice for an hour, or fifty minutes four times a week, or forty minutes six times, or in four one-hour periods. In a majority of cases the time chosen for exercise lies between ten and one o’clock, though the hours from two to four in the afternoon are used not infrequently. Military exercises take the place of gymnastics for boys of the sixth to ninth years in the early part of every fall semester, occupying three hours daily for twenty days as a rule, and during this period their usual school duties are cut down by a corresponding amount. Each of the seven schools has its special teacher of gymnastics, and no one is eligible to such a position until he has completed a two-years’ professional course at the Central Institute of Gymnastics. In the fall of 1900 these teachers and their assistants were all officers in the army, and five of the nine were on the staff of instruction at the Institute. One had the rank of major, and the rest were captains and lieutenants. Occasionally a “weak section” is formed of boys selected from the whole or part of the school, but in general the division into classes is based upon school grade, the boys of the sixth to ninth years exercising together as a rule, and the rest variously subdivided according to their numbers. The size of some of these classes is noteworthy. They rarely contain fewer than 60 or 70, while 100-125 is not an unusual number, and 150-200 are sometimes seen together under a single teacher. To facilitate the handling of so many it is usual to separate them into squads of from 12 to 20, on the basis of physical fitness, and to place at the head of each squad one of the best pupils, who sees that his portion of the lines is correctly formed at the beginning of the hour, reports upon attendance, and directs the work of his division when the teacher is not giving commands for the whole class. Before exercising it is the practice to remove coats, collars, cuffs, and suspenders, and the dickey, or detachable shirt-front, if a boy has arrived at the dignity of wearing that common article of clothing. Shoes are exchanged for rubber-soled canvas slippers, of the sort so often seen in American gymnasia.
