HOW TO TREAT A WOUND.
If it is only a flesh-wound or slight cut, wash it with cold water and bandage it with a clean, white rag. The edges of a deep cut should be drawn together and held in place by narrow strips of adhesive plaster, fastened across the wound from side to side.
If the cut is very deep, and the blood flows very freely, send for a doctor. While you wait for him, knot a handkerchief, or suspender, or towel, in the middle, and twist it very tightly over the cut artery, above the wound. If a vein has been severed, twist the knotted handkerchief below the wound. If the blood continues to flow, tie a bandage both above and below the hurt part.
