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.
