s to get all the lung
space possible. By constantly reminding children of these little points
you will be amazed at the progressive improvement which goes on both in
their bodies and in their minds. They will become little missionaries,
they will tell the story to others, and a real good can be accomplished
in this simple way, that will grow in strength and vigor as the years
roll round.

The next suggestive feature in the reading of "How we catch disease," is
the significant emphasis which is put upon sunlight and fresh air in the
treatment of consumption. Sunlight, as already stated, is the great
enemy of microbes and germs of all kinds. Where sunlight is, germs do
not want to be. How wrong, therefore, is the habit of lowering the
shades, when the sun shines into your home, because it "spoils the
carpet." Let it spoil the carpet; it is much cheaper to buy a new carpet
than to pay for a funeral. Let the sunlight stream into your rooms for
the few hours it can every day. Germs love the dark, sunless corners
where the dust is. Housewives should, therefore, go into the dark
corners with a moist duster, and wipe them clean, then boil the duster
and hang it in the sunlight to dry until needed again. If you choose to
use a feather duster instead, as the lazy woman does, you only chase the
dust and the germs from one corner to another, and in doing so you
afford yourself the opportunity of swallowing a few germs in the
passing. One may, therefore, be punished in an unexpected way for being
lazy.

For the very excellent reason that corners and angles are unsanitary,
there are to be no more of them in the construction of houses and office
buildings of the better class. They are being built with "round"
corners; even the ceiling and walls, and floor and walls, meet in a
curve,--no square crevice or corner where dust or germs can gather.

If we add moisture to a sunless spot, we have the ideal environment for
germs to breed and flourish in. There is always moisture or humidity in
the air if the altitude is low, and if it is near the ocean, or any
large body of water, the moisture is relatively greater. For this reason
we send patients with pulmonary disease to the mountains, where the
altitude is much higher, where there is no moisture, and consequently
where there are practically no germs. We cannot move our homes to the
mountains, however, so what must we do to get rid of the moisture and
the germs where we are compelled to
