lo6 EXERCISES OF PROGRESSION. [SECT. Il. a large portion of the leg also is fashioned and placed to aid in its performance; the mass of muscle forming the calf of the leg has for its primary object to raise or lift the heel, while the toes have yet the ground for fulcrum, anticipatory of the forward act of propulsion of the next step; and it is this gradual, springy action, which at once gives development to the limb, and in return receives from the limb elasticity and spring in proportion to its development. The initiatory practice in walking should be per- formed quite irrespective of time, correct action and position 1eing the sole points to be aimed at; these acquired, the longer courses should be used. The action and position in walking are the same for all degrees of 'Speed, except that as the speed is in- creased all the featmtes of the position become more distinct and prominent, and all the points of the action are intensified: the step will be wider, yet never so wide as to cause additional effort; a stronger act of propulsion will come from the rear foot, a more distinct transition from heel to toe will take place on the ad- vanced one; and the natural oscillation of the upper limbs to front and rear, alternating with the action of the lower ones, ·will become more energetic and in a great measure regulated by the muscular contrac- tion of the limbs themselves. ---------------------~
