require that exposed surfaces of manure on platform cars or in stables, 

 yards and fields be either screened or treated once a week to prevent the 

 breeding of flies? 



Eemedies for Flies 



Screen buildings: and prevent flies from breeding. 



All living rooms in houses, and especially the kitchen and dining 

 room, sick-rooms, and all hotels, restaurants, markets and stores where 

 food supplies are sold or stored should be fitted with screens to. keep 

 out flies. 



Breeding places of flies should be abolished where possible by not- 

 allowing manure, garbage or filth to accumulate or by screening* it to 

 keep flies away, or by treating it to kill the maggots. Manure treated 

 with chloride of lime each day will not produce flies. Kerosene or one 

 of the so-called soluble or miscible oils sold everywhere for spraying 

 orchards will probably kill the maggots if the outer two inches is satu- 

 rated with the liquid. 



Flies in houses may be killed by the use of insect powder, fly-paper, 

 or by five-per-cent. sweetened formalin placed about the rooms in 

 saucers. A recent circular 12 from the North Carolina Agricultural 

 Experiment Station recommends one tablespoonful of commercial 

 formalin (40 per cent.) to a half pint teacup of half milk and half 

 water. The liquid is exposed in a shallow plate with a slice of bread 

 in it to give more space for the flies to alight while drinking. The 

 author of this circular, Professor E. I. Smith, states that in this way 



Horse Manure piled in the Suburbs, in a suitable condition to breed many flies.
