(c) Lung Compression. You kneel on the ground straddling the patient’s hips and facing his head. Place your hands so that the little finger closes over the end of the lowest rib and the heel of your hands so placed on the sides as to allow you to exert all your strength downward from your shoulders until the patient’s lower chest region is compressed. You hold this compression for three seconds and then remove the hands and allow the patient’s chest to refill. Repeat the compression and lung refilling fifteen times a minute for two hours if necessary. (d) After breathing is established keep the patient in a recumbent position until breathing is regular and put him in a warm place and surround his body with heat in some form such as heated stones wrapped in cloths, hot blankets, etc. If available for use aromatic spirits of ammonia on a handkerchief held to the nose is stimulating. Colds. Take a hot bath and a heroic dose of physic. For the aches and pains take aspirin tablets (grains 5 each) one every hour for 4 doses then one every 4 hours. If the throat is sore gargle with salt water. Diarrhœa and stomach cramps may be due to bad water or improper food. The results are bowel pain and too frequent movements and general weakness. Stop all food and rest the patient in bed entirely. Take a purge and after three good movements take a Sun Cholera tablet each hour until three are taken then one every three hours. If without medicine use flour mixed with water. In Sunstroke the skin stops perspiring, the skin over the ribs is hot and dry, the face red and the head feels great pressure of too much blood. Get to a cool place, lie down, loosen the clothing and bathe the face, chest and wrists in cold water and drink as much water as wanted. In Heat Exhaustion the conditions are opposite--the face is pale and the skin sweaty. You need stimulants such as tea or coffee and are not to bathe the skin.

Again perchance some get rich quick frenzy pushes you into the frozen regions in exploratory reconnaissance for precious metals.
