watermelons, and pumpkins are really fruits, though they are not
generally so called.

~7.~ The seeds of grass-like plants are known as _grains_, of which we
have wheat, rye, barley, corn, and rice. There are a few seeds that grow
in pods, such as pease and beans, which somewhat resemble grains.

~8.~ We eat the leaves, stems, or roots of some plants, as cabbages,
celery, turnips, and potatoes. Foods of this kind are called
_vegetables_.

~9.~ There are other things, which, if we eat or drink them, will make
us sick or otherwise do us harm. These are called _poisons_. Only such
food as is pure and free from poisons is good or safe for us to use.

~10. Narcotics and Stimulants.~--There are a number of substances known
as narcotics and stimulants, which, from their effects upon the body,
may be classed as poisons. Tobacco, opium, alcohol, and chloral are
included in this class. Death has often been caused by taking small
quantities of any of these poisonous drugs. We shall learn more of the
effects of tobacco and alcohol in future lessons.


SUMMARY.

1. Our bodies are made of what we eat.

2. Things which will help us to grow strong and well, if we eat them,
are foods.
