A tent may be made fly proof by having a cheesecloth interior which is an exact replica in shape of the tent, the body very loose and voluminous and no openings except when the sides are raised. It is suspended by cords and tapes and is absolutely protective. The insect repellents used as body applications consist usually of some essential oil incorporated in a lasting base of thick oil or salve which establishes a durable glaze over the skin, preventing too rapid evaporation of the oil by the body heat. These “dopes” do not injure the skin a bit and the slight discomfort they may cause is compensated for by the immunity established. In mildly infested districts oil of citronella applied to the skin will suffice, but where they come at you in swarms a glaze on the skin is needed to hold the essential oil for more continued use. The following formulæ are successful: NESSMUKS DOPE No. 1. Pine Tar 3 oz. Castor Oil 2 oz. Oil Pennyroyal 1 oz. No. 2. Pine Tar 1 oz. Oil Pennyroyal 1 oz. Vaseline 3 oz. Phenol 3 oz. No. 3. Oil Citronella 1 oz. Spirits camphor 1 oz. Oil Cedar ½ oz. WOUND TREATMENT The first thing is to stop the bleeding by simple pressure with the cleaned finger over the bleeding part or applications of hot water cloths. Once a clean clot is formed don’t destroy it. Never use the homely cobwebs to stop bleeding as they reek with germs of blood poison. The second important step is to exclude pus germs. They are fewer in the woods than in the city, but we must be exceedingly careful. Wash the injured part well in hot, soapy water then rinse with water that has been boiled and cooled. Apply the First Aid wound dressing. If the wound is inflamed and discharging pus clean as well as possible and keep the dressing wet with cooled boiled water, reapplying every three hours or sufficiently to keep the dressings wet. On a non-inflamed wound simply apply the First Aid dressing which is sterile and devoid of germs. In a sprain the ligaments become bruised or torn, there is loss of function and pain with inflammation. Pour hot water on the injured joint for an hour at a time, repeating every two or three hours for a day. (If no receptacle is at hand to heat water in fill a hollow rock, log, or waterproof cloth pocket with water, heat a stone in camp fire and put in water for heating.) Bandage the joint and keep applying hot water. Keep the limb elevated. When the swelling goes down rub the skin with oil or grease, gently massaging the injured parts. Don’t over exercise so as to reinjure the torn ligaments. Walking off a sprain won’t cure it, in fact only prolongs recovery.
