First, get your patient into camp if he is away from it. That may be done in the following manner, which will also illustrate how to carry a person injured in any manner: take a blanket and lay it at full length on the ground; place a pole two feet longer than the blanket directly in the center and fold the blanket over it; lay a similar pole in the center of the folded half and fold the free side back over; place your patient on top, and two men can carry him as comfortably as though he were in a litter. It is, in fact, an emergency litter. Another emergency litter may be constructed by buttoning an overcoat its full length and running two poles down the sides, laying the patient between them. Failing an overcoat, two short coats or Mackinaw jackets may be made to serve. Having got your patient with the compound fracture into camp, cut off all clothing from the wounded limb, but no more. It is a bad plan to remove too much clothing from badly injured persons. All the warmth must be conserved, even to the extent of applying artificial heat. Examine the wound for foreign matter and carefully remove it, especially bits of clothing, leaves, small sticks, and bits of earth. While you have been thus engaged, water should be heated in the cleanest, brightest vessel the camp affords. If there are none bright enough, one may be sterilized by burning it over a hot fire for at least ten minutes. It is absolutely essential that the water used to cleanse a wound of this character should be sterile—that is, without any germ life whatever; hence the directions for boiling it. In another clean vessel boil all the cloths, towels, and other dressings that you intend using. Any soft cloth will do for dressings, provided it is sterilized and sterilization consists only in thorough boiling. One of the articles I shall mention in a very limited surgical kit is a bottle of tablets composed of bichloride of mercury known as Bernay's tablets. They are made by all chemical houses and vary in form, but all contain about the same quantity of the antiseptic agent. Some are white and some blue in color, the blue being preferable. One of these tablets dissolved in a quart of water makes a solution of about the proper strength for dressing wounds. Make your solution and with your sterilized cloths wash out the wound thoroughly, and that does not mean to let a little water flow over the wound; it means to remove every particle of foreign matter in and about the wound. If the bones have stuck into the earth, as is quite often the case, they must be exposed and the narrow canal cleaned. Then replace the bones in as nearly their proper position as possible. Do not attempt to "set" the bone; just put it back fairly nearly in line. Then cover with several layers of moist cloth that have been previously boiled and dipped in the bichloride solution.
