a piece of cloth or handkerchief, twist it
cornerwise, and tie a hard knot midway between the two ends. This
knot should be placed over the artery, between the wound and the
heart, and the ends carried around the limb and loosely tied. A stick,
five or six inches long, should be placed under the handkerchief,
which should be twisted until the knot has made sufficient compression
on the artery to allow the removal of the fingers without a return of
bleeding. Continue the compression until a surgeon can be called.

380. When an artery of the arm is cut, elevating the wounded limb
above the head will tend to arrest the flow of blood. In a wound of a
lower limb, raise the foot, so that it shall be higher than the hip,
until the bleeding ceases.

_Illustration._ On one occasion, the distinguished Dr. Nathan Smith
was called to a person who had divided one of the large arteries
below the knee. After trying in vain to find the bleeding vessel, so
as to secure it, he caused the foot to be elevated higher than the
hip. At the first instant the blood was forced from the wound about
twelve inches; in a minute, it was diminished to three or four; and,
in a short time, the bleeding ceased. This Dr. S. called his "_great_"
operation; and it was truly great in _simplicity_ and _science_.

381. The practical utility of every person knowing the proper means of
arresting hemorrhage from severed arteries, is illustrated by the
following incidents. In 1848, in the town of N., Mass., a mechanic
divided the femoral artery; although several adult persons were
present, he died in a few minutes from loss of blood, because those
persons were ignor
