“2. _Vocational training_ and industrial occupations supply a certain amount of motor activity for a large part of the population, it is true, but in forms which are in general too one-sided and too much limited to the accessory mechanisms of the hand and fingers to be of serious hygienic value, and too often they are practised under insanitary conditions. The isolated exercises of _formal gymnastics_, if wisely chosen, are serviceable for corrective purposes, and may be utilized for bringing into play the fundamental muscle groups, and securing erect posture and a good degree of neuromuscular control. They permit a maximum economy of time and space and offer the advantages of skilled supervision, and they may be made to yield a foundation of strength and skill without which interest and success in games are likely to be lacking. Carefully selected and arranged exercises in _hanging and climbing_ and in _jumping and vaulting_ are especially valuable as supplying elementary training in self-confidence, alertness, decision, and courage, in addition to their hygienic and corrective uses and the advanced training in coördination which they furnish. _Combat exercises_ make their unique contribution in the form of capacity for self-defense and ability to take punishment coolly. Folk, esthetic, and athletic _dancing_ have an obvious place with relation to fundamental muscle groups and graceful control of the body as a whole. _Group games_, which are lacking in corrective value and compare unfavorably with formal exercises as a school of good posture and general coördination, may give excellent results in the way of improved health, and their special field is the development of sturdy character and right ethical standards.
