The HoUSe-Fly : Disease Carrier. 



An Account of its Dangerous Activities and of the Means of Destroying it. 



By LELAND O. HOWARD, Ph.D. 



Chief of the U.S. Bureau of Entomology. 



With numerous Illustrations. 



Careful scientific investigations have now fully established the fact that the common 

 house-fly, besides being a nuisance, is a dangerous pest which distributes the germs of 

 typhoid and other diseases. In this book the Chief of the U.S. Bureau of Entomology sets 

 forth complete information about the fly. 



After describing the nature of the common house-fly, its habits and methods of breeding, 

 he proves his case against it as a carrier of disease, and goes on to what will be the most 

 interesting section to most readers — that on remedies and preventive measures. He considers 

 screening, fly traps and various poisons, repellents, and the treatment of breeding places. 

 A special point is made of the possibilities of action by communities, with suggestions as to 

 organisation, publicity, interesting the children, and the work of Boards of Health. 



Dr. Howard's previous experience with the mosquito warfare, combined with his ability 

 as head of a bureau which has grown under his direction to be " the first entomological 

 centre in the world," has made a book which will not only interest scientifically, but is of 

 practical use and of vital importance. The extermination of the house-fly is much to be 

 desired as a means to public health, but it can only be accomplished by the widest publicity 

 and a full understanding of the subject.
