ould not do as they pleased
because they belonged to their masters whom they must obey or else
they would suffer punishment. No boy can begin the use of tobacco
without the danger of becoming a slave to it.

The use of tobacco either by chewing or smoking gradually causes in
any one the growth of an appetite which makes him feel miserable and
unhappy unless it is kept satisfied. It can be satisfied only by the
use of more and more tobacco.

Many men would like to quit the use of tobacco if they could do so
without suffering. They are slaves, and tobacco is their master.

=Cigarettes and Health.=--A cigarette is a tube of paper filled with
tobacco. The tobacco is usually not so strong as that used in cigars
and pipes. For this reason, boys like it better, and because it is so
mild they draw the smoke down into the lungs. This gives the poison a
better chance to be taken up by the blood. On this account, and
because one is likely to smoke oftener when he smokes a small piece of
tobacco, cigarettes are thought by some to be more harmful than the
use of tobacco in pipes and cigars.

=Tea and Coffee.=--Tea is made from the dried leaves of the tea plant.
Tea plants are raised in North Carolina, China, and Japan. The drink
called tea used at the table is made by pouring boiling water on the
tea leaves. The leaves should not be boiled as this draws out a
substance which keeps the stomach from doing its work in the right way.

Coffee is the seed of a plant growing in South America and Asia. It is
roasted, then ground, and boiled in water to make the drink called
coffee.

Children should not use either tea or coffee as they are likely to
hurt the stomach and may injure the heart. One or two cups of tea or
coffee daily seem to have little or no bad effect on the health of
most grown persons. Coffee taken at supper may keep one awake by
sending too much blood to the brain.

=Opium and Morphine.=--Opium is a dangerous drug which is got from the
heads of the white poppy plant grown mostly in the far East. From
gashes cut in the poppy heads a juice runs out and hardens into a gum
from which the pure drug is made.

Some persons smoke opium for the drowsy and pleasant feeling it gives.
Its use is very hurtful and ruins both body and mind. _Morphine_ is a
pure form of opium. Pe
