412 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 10 



The following buildings were shown: dwelling, dairy barn, horse 

 barn, hog house, milk house, and outdoor toilet. The only necessary 

 farm building lacking was the poultry house. Every building was 

 fitted with screens over windows and doors, and the hog house had 

 swinging doors into the run-ways, with miniature pigs passing through. 

 At the door of the dairy barn was shown a miniature manure spreader 

 receiving a load of manure from the manure carrier and ready for the 

 daily removal to the field. On the other side was a model of a maggot- 

 trap. At the horse barn were shown manure bin and manure closet 

 for we knew that many of our visitors would be from villages and towns 

 where such outfits could be used. 



The milk house was removed from the stables, and beside the water 

 tank. Windows and doors were fitted with screens, and a screened 

 enclosure contained shelves on which pails and tins were airing. The 

 dwelling, besides screens on windows and doors, was provided with 

 screened porches, both front and rear. At the back door was a gar- 

 bage tin. A portion of one side of the house was removed to show con- 

 nection of kitchen sink and washbowl, bathtub and closet in the bath 

 room, with a sewage system. At a convenient distance from the house, 

 a model Imhoff septic tank was let into an excavation, connections to 

 the house and outlet being indicated. The outdoor toilet was a perfect 

 model of a flyproof, sanitary privy, of the bucket type. 



An abundance of labels explaning every detail and a leaflet, which 

 had been prepared on fly control to accompany this exhibit, gave full 

 information to those who did not wish to ask questions of the attend- 

 ants. 



The success of this exhibit was much greater than had been antici- 

 pated and many people went away with a definite idea about farm sani- 

 tation, especially about the construction and use of septic tanks. 



The cost of the models was not very great, approximately six weeks 

 were required for construction. Labor and material have totaled 

 about S200, the cost of publishing the fly leaflet being in excess of this. 

 This year the flyless farm has been again exhibited at the State Fair, 

 at the request of the Women's Federated Clubs, and will also visit 

 several county fairs. 



We are making additions to it as they suggest themselves. For 

 example, this year we have added a model of a mosquito-proof water 

 tank at the corner of the house. The models are very durable and we 

 hope will last long enough to visit every county fair in the state on 

 their mission of better farm sanitation. To the average individual in 

 Minnesota, whether rural or city dweller, it conveys more practical 

 information on the house-fly question, than all the leaflets we have 

 ever printed.
