Concrete Barn Floors
Investigations of the Department of Agriculture have disclosed the fact that many cases of typhoid fever and malaria, often considered unaccountable in their origin, are the result of the germs being carried by the house-fly. Screens, flypaper, and poisons are all very well, in a small way, but to free the place of flies means getting rid of the conditions which produce them. Leaving out the manure pile ([see Manure Pits], page 45), the favorite breeding-place of flies is the foul floors of the cow and horse barns. The barn can be almost entirely rid of flies by building floors and manure pits of concrete.
