to furnish excellent ventilation. The SheiTingham window is good; 

 this is simply a triangular piece of metal or wood placed at the side 

 of the window so that it can be drojDped out at the top and the 

 air be deflected toward the ceiling instead of striking directly on 

 the cattle. The removal of the windows and the substitution of 

 cloth has sometimes been recommended; this does not give good 

 results for the reason that the air of the cow stable contains a good 

 deal of moisture and some dust, and the meshes of the cloth very 

 soon become stopped up, so that air does not pass through readily. 

 It is undoubtedly a good method for the sick room. 



In conclusion, the writer would urge any one who is planning to 

 build or rebuild a dairy barn (1) to visit as many other barns as 

 he can; (2) to allow for expansion of the business; and (3) to draw 

 plans to scale a year before building operations are begun; the last 

 will save expense, as it is easier to correct mistakes made on paper 

 than those made with actual building materials. In the study of the
