"A single human hair indicates.

too moist or too dry. A pc. fectlY dry
air is put at zero. Saturated air, that
is, air carrying all the moisture it will
hold, is put at 100. The human hair
bsorbs moisture, and, like a rope, be-
comes shorter when wet. The differ

in the air varies. 1t it becomes too dry,
more steam is thrown in; If too moist,
less. steam is allowed to escape. And
thus the atmosphere is regulated at q
wholesome point.-Washanqton Post.
