used, and treat the inside with a good whitewash mixture made to 

 adhere well. The latter will act as a cleanser and disinfectant. 

 All window sashes should be well painted. If roofing paper is 

 used, the directions that come with it should be followed closely. 

 Where extremely cheap buildings are constructed of rough lumber, 

 the cost of painting them may be too great. Whitewash may be 

 applied with a spray pump. 



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.
