slowly down the
stream; how powerful they look. They have their searchlights on, looking
for any enemy that may appear upon the surface.

Further on some germs or bacteria are coming up the stream; they may be
pneumonia germs, or typhoid germs. These are the Captains of the Death
Armada. The Dreadnoughts pull up along side. War is declared, a battle
royal is on. The victory will go to the strongest. When the smoke clears
away we may see the Dreadnought sailing calmly down stream. Where now
are these mighty Goliaths, the typhoid or pneumonia germs? As the
Dreadnoughts were in good fighting trim, we may find them on the inside
of the engine-room of the Dreadnought. They are being used as fuel in
its furnace.

Sometimes the battle is in favor of the germs, and the Dreadnought is
destroyed by the germs.

This happens when the little round freight boats have not found a full
cargo of fresh air and oxygen waiting for them in the Lung Station.

All this happens in this wonderful stream.

If we look further we would find that the muscle men in the muscle
countries are busy making heat to keep our bodies warm. The little
workmen in the gland country are making fluids to mix with the food we
eat. The fluids change the starch, the sugar, and the meat we eat, so
that the muscle men can use it to build us large and strong. The little
workmen in the skin are pouring water out of it in order that we may
keep clean and cool.

This wonderful stream carries all these things from one country to the
other, exchanges the produce of one country for the produce of
another--so to speak.

The little freight boats on this stream cannot do the work they were
intended to do, the Dreadnoughts cannot overcome and disable the germs
that get on their decks, if they are not kept in the very best
condition. The only way in which we can keep them "fit" is by living
according to the rules of hygiene.

Eat wholesome food.

Take outdoor exercise.

Sleep with the windows open.

Drink pure water.

Bathe the body frequently.
