Description:
A sudden mine disaster, by which scores and even hundreds of lives
are lost, receives nation-wide attention; but deaths caused by typhoid
fever, diphtheria, tuberculosis, etc., caused by unsanitary dwellings,
foul air, infected water, and the like, may carry off their toll, with
few voices raised in protest and fewer still proclaiming remedies that
are practical.
Much sickness is caused by germs getting into the human system
and, of course, the way to prevent disease is to keep them out. These
germs exist by the million, in everything and on everything, and they
are so very small that they cannot be seen by the naked eye. It takes
350,000 typhoid fever germs side by side to form a line one inch long.
From 200,000 to 1,000,000 bacteria have been found in one cubic
centimeter of earth. Most of them, though, are perfectly harmless. 6 p.
