the split ends are crossed so that they may
be tied over different parts of the head and thus hold the bandage more
securely in place. For instance, in the jaw bandage the uncut middle
part is placed over and under the chin, the ends crossed, and two ends
tied at the back of the neck and two over the top of the head.

_Roller Bandages_--Roller bandages are a little more difficult to put on
so that they will stay on, and at the same time be smooth and have a
uniform pressure on the part of the body bandaged. This last point is
most important.

Rules for applying roller bandages:

1. Lay external surface of bandage against the part to be bandaged,
holding the roll in the right hand, unless you are left-handed,
unrolling it as a roll of carpet unrolls to show you a pattern in the
shops.

2. Hold the loose end with the left hand and catch it with two or three
turns of the bandage before beginning to put on the bandage. Never have
more than four or five inches of the bandage unrolled at once.

3. Be careful to have the same pressure from every turn of the bandage.
This is most important if the bandage is to stay on and be comfortable
and not interfere with the circulation of the blood. Judgment of the
pressure is only acquired by practice, and therefore you should practice
enough to acquire this before the real emergency happens.

4. Do not bandage too tightly. Blueness of the skin above or below the
bandage always means the bandage must be loosened. Remember in applying
a bandage immediately after an injury that considerable swelling may
occur later, and apply your bandage more loosely than if bandaging after
the swelling has gone down. Always loosen a bandage that is tight enough
to cause pain or blueness.

5. Bandage from below upward. That is, from the tip of a finger or toe
toward the hand or foot. From the hand or foot toward the shoulder or
groin. This is in the general direction of the return of the
circulation.

6. Bandage over a splint and not under it.

7. Bandage arms, legs, fingers, etc., in the position the patient is to
keep the part in when the bandaging is completed. For instance, bend the
elbow to a right angle before putting on the arm bandage. This will be
more comfortable for the patient, allowing him to carry the arm easily
in a sling and also permit him to use the hand to some extent if the
nature of the injury will permit. In bandaging a leg both above and
below the knee, the bandage must b
