Since boys are apt to be moreinterested in speed than in posture it is important to teach themhow to follow the pedal with the foot and to have their bicyclesequipped with toe clips, so that they can get the racers speedwithout his characteristic hump. CHAPTER OCCUPATIONS. The bodily movements involved in iadustrial occupations, likethose of play and sport, include both the handling of objects andlocomotion. In sport locomotion is perhaps the more prominentof the two, but in industry the reverse is true. This has come aboutbecause in the displacement of muscle by machinery it is the fieldof locomotion that has been invaded most.
