good repair, byreplacing any broken or rotten parts, and also by pro- 
tecting them against the elements by keeping the outside covered 
with a good paint. Buildings should be painted as soon as built, and 
kept well painted, both for looks as well as permanence. Whitewash 
may be used on the interior as a preservative, it acting as a filler. 
Tar is one of the best preservatives known. It is a by-product 
from coal in the manufacture of gas and is very cheap. It may be 
diluted with gasoline and used in warm weather without artificial 
heat. It should be used on all posts, sills, and parts exposed to 
great moisture. It is suitable for all kinds of roofs except those 
covered with tin. It is used also to paint the outside of buildings, 
but its monotonous black color should be relieved by yellow or 
other appropriate trimming. Tar will last longer than oil paints, 
is much cheaper, and preserves wood better. It may be used on 
the dropping boards, roosts, and nests to fill crevices where lice 
would hide.
