Any of the vessels of the lower limb may be controlled by compressing just behind the knee between the two prominent tendons that will be found there when the leg is doubled up. Arteries of the forearm and hand can be stopped by pressing with the thumb at the elbow joint just to the inner side of the tendon of the biceps which you may feel like a cord when the arm is extended. If the bleeding is from the upper arm stretch the whole arm by raising it above the head. Feel in the armpit and you will locate a prominent ridge on the inner side; press with your fingers just behind that ridge and you will shut off the blood supply from the whole arm. These are the more prominent vessels that lie near the skin. Certain of these larger arteries require ligation. The ligation of an artery calls for a certain amount of surgical skill, but if it is necessary to save life you can do it. Surgeons now use sterilized catgut for the purpose, but silk can be used as well, taking care to leave sufficient end hanging out of the wound to remove it by. After having made compression and controlled the hemorrhage, clean out the wound and loosen your tourniquet until the blood spurts. Locating the artery, grasp it in the bite of the hemostatic forceps. Cut off a short piece of silk and tie it loosely around the forceps. Have some one pull up on the forceps and at the same time with your forefingers slip the knot down over the end of the cut vessel. Tie tight and remove your forceps. This procedure will be necessary only in case of injury to large vessels. Smaller arteries can be controlled by the means hereafter described, or by placing a heavy pad of gauze over them and making compression with a tight bandage. The blood will become entangled in the meshes of the cloth and form a clot. Incised wounds inflicted with sharp instruments will be found to comprise practically all the injuries occurring in the woods. The method of treating one will illustrate that of dealing with all. Let us suppose that in cutting firewood the camper has had the misfortune to drive a sharp ax into his instep (a quite common accident). The blood spouts at once in a very alarming manner. He hobbles to the camp and removes his shoes. An ugly gaping wound appears, from the bottom of which blood is jetting, indicating that an artery has been severed. The first thing necessary is to stop the blood. Take a handkerchief or other cloth and tie it about the ankle rather loosely, place a small stick or a table fork beneath it and twist. In a few turns you will note that the blood is flowing with less force and shortly will cease altogether.
