tains some moisture, and in a short time swarms of 

 young flies emerge, Tiie removal of such material pre-

 part of the food supply of the old insects. In many 

 cases stables can be protected by fly-screens, or darkened 

 so that the flies will not pester the inmates. Animals 

 can also be well protected in some cases by the use of 

 individual fly -nets. There are upon the market some 

 excellent remedies which, when applied to the skin of 

 the animal by means of a brush or spray, are offensive 

 to flies and will protect the animal until the applica- 

 tion evaporates. 



A solutibn of one part of carbolic acid in twenty 

 parts of water, or a solution of one part of creolin or 

 similar coal-tar product to fifty parts of water, sprinkled 

 about the stable, tends to keep the flies away, as well as 

 to disinfect the stable. 



MAGGOTS 



Most of the maggots on animals are the larval or 

 "grub" stage of the flesh-fly which swarms about dwell-

 larvse on fresh meat, as well as on the surfaces of 

 wounds, especially where the tissues have been injured 

 to a considerable depth. It also deposits larvae in the 

 wool of sheep where it has collected manure and other 

 filth and become matted. The larvae may then work 

 their way into the skin, causing extensive sores, which 

 may result in the death of the animal. 



There is considerable irritation, as shown by the ani-
