Tree work will not alone produce muscle; it will promote self-reliance; it will confer agility and Iftheness. In addi- tion, the rough and tumble portion of the exercise will work immense benefit by in- worting the body, wholly or in part, and thus sending the blood bounding to parts that require a reinforced biood supply at times, but seldom get it. This is particu- larly true of the head. Hang by your legs for a few moments and when ‘you resume your normal position you will find that its unusual blood supply has cleared the brain wonderfally. So with other parts of the body. To do tree work properly it 15 not nec- essary to wear a dress suit. A pair of old but strong trousers, an outing shirt and rubher-soled slippers compose the most appropriate outfit. Dressed in this manner you will be ready for all that en- sues and will not be likely to have your mind distracted by .a sudden rent in trousers or shirt. The four exercises described are but samples of many exhilarating movements that can be studied out with little or no . 3 apparent effort. Indeed, after a few days of scrambling about a thousand and one different exercises will occur to the mind. Limit the exercise by no rule other than the approach of wearine And don't become dlzcouraged over a skinned arm or shin. -Good, pure blood, such as is ob- tained by tree work, soon brings new skin. 1. Drawing Up Exercise—Search out a convenient and strong limb just beyond your reach and jump for and get a firm hold on it, Then, keeping the feet straight toward the ground, try to raise up the body by the power of the hands and place the chin over the limb. In like manner raise the body until the Hmb is in the middle of the abdomen. After these exercises have been execut- ed until weariness results, spring to the ground on the toes and with the knees bent. When you are rested recover the limb with the hends and this time prac- tice drawing up and throwing the legs over the limb, singly and together, inside and outside the space of the hands and bringing yourself to a sitting posture. Each and all of the various movemenis are fine for the whole upper part of the bedy, the arms and shoulders being es- pecially deveioped, while the lung power is materially increased. Figure 1 shows how the body is drawn up to the chin or to “stomach™ the umb. Tre legs are thrown over the limb from the same vos'tion. II. Hanging by the Knees.—Climb up the tree trunk to a suitable imb and sit on it, with legs dangling. Holding on with bands, gradually let the upper part of the bedy hang down until the limb is in the crotch of the kneées. Then, when the legs save a firm hcla on the ltmb, loosin the rands and remain in this positioa for a few moments. ' ‘When you Pave become accustomed, AI‘UIZFJ‘ By 1NA/ TUM after several trials, to this Inverted post- ton, attempt, by the power of ih dominal muscles alone, to rz N bedy so that the hands can the . agait. lin The exercise can be varied by swaying the body backward, forward and side- wise. It Is splendid for the legs and the abdominal region. The lue of the blood rushing to head and chest can not be overestimated. It Is a condition that rarely occurs in civilized life, much to the detriment of the buman system. A good neck exercise can be secursd while the body is inverted by turning the head with the body as it sways, and by lifting the head up and trying te look backward at the heels. The heels will not be seen, but the muscles of the front part of the neck will be benaficially stretched. Figure 1 shews the first position for the exarc! IIL. Limb Traveling.—Grad a conveni- ent limb on either side, with the hands close . together, preferably touching. Draw up and interlock the legs over the Umb. Then, keeping the legs in the orig- inal position, travel hand over hand away from them until the body can be out- stretched no more. (Figure 3.) After re- taining this position for a few moments travel back until the bands almos the kuees. ‘While the body is outstretched frequent- ly draw up the arms until chest and head touch the limb. The entire exercise upb of the chest, the back of bands and arms gen touch s the fromt the legs and the IV. Limb Climbing.— b the tree to a handy ltmb.
