=SNAKE BITE.=--There are many different species of poisonous snakes in
the United States. The more common are the rattlesnake, the moccasin,
the copperhead, and the common viper.

All the venomous snakes have certain characteristics by which they may
be distinguished from their harmless brethren. The head is generally
broad and flat and of a triangular shape, the wide, heavy jaws
tapering to a point at the lips. There is a depression or pit between
the nostril and eye on the upper lip, hence the name "pit vipers"
given to poisonous snakes. The pupil of the eye is long and vertical,
of an oval or elliptical shape.

Venomous snakes are thicker in proportion to their length than
harmless snakes, the surface of their bodies is rougher, and their
tails are blunt or club-shaped. Conversely, harmless snakes possess
long narrow heads, the pupils of their eyes are round, not vertical
slits, and their bodies are not thick for their length, but long and
slim with pointed tails. The bite of vipers of all kinds is much more
poisonous in tropical regions, and in the North fatal snake bite is a
rare occurrence.

If there is a doubt whether a snake is poisonous, the neck may be
pressed down against the ground between the jaws of a forked stick,
and the poison fangs looked for without danger. These hang directly
down from the front part of the upper jaw, or are thrust horizontally
forward just in front of the upper lip, and may drip saliva and venom.

In Cuba and Porto Rico there is a viper called Juba, or Boaquira,
which is a counterpart of the Northern rattlesnake, and the most
poisonous of the many species in that region. Among venomous species
of the Philippines are two boas and also a viper from nine to ten feet
long, which exceptionally pursues and attacks man. This snake is
easily killed by a blow on the neck. Another small viper with a
club-shaped tail, inhabiting these islands, is nocturnal in its
habits, and may get into boots at night. Boots, therefore, should
always be inspected before one puts them on in the morning.

Usually it is only the young, old, and weak who succumb to snake bite.

=Symptoms.=--The symptoms of snake bite of all poisonous species are
similar. At first there is some pain in the wound, which rapidly
increases together with swelling and discoloration u
