KEEPING ANIMALS HEALTIIY 493 
ple who seek to avert disease by disinfection and still 
allow filth to accumulate are penny wise and pound fool- 
ish, for they must sooner or later pay the penalty. Suc- 
cessful farmers keep their farms clean and insist on 
cleanliness in every place where the farm animals are 
housed or permitted to live. In filth, flies, germs, ver- 
min and other terrors are propagated and from such 
places they spread far and near. 
8. Damp quarters.—Bacteria require moisture and 
darkness for their propagation. They rarely survive 
when dried or exposed to light. Hence, in damp houses | 
and barns the occupants are not only constantly sub- 
jected to distress, but also to danger. The only thing 
to do with damp quarters is to correct the trouble. A 
drain pipe at the side of a barn often will make dry a 
stable floor. If the walls are damp, the fault may be with 
the form of construction or to lack of window space, or 
to a lack of fresh air. Whatever the source of trouble, 
let nothing delay its early corréction. Good health is 
not often associated with damp 
quarters. 
9. Ventilation—Fresh air is 
not a fad. It is neither a luxury ~ 
for humans nor a fancy for 
beasts, but a necessity. It is 
lung food for both, and should 
be pure and abundant. Every 
house should supply 800 cubic 
feet of air for each occupant, and 
every stable 1,500 cubic feet for 
each mature cow or horse, and nt 
this should be removed fre- [ten me entity 
quently. Ventilation is primarily Fresh air is admitted from the top.
