MYIASIS— ITS PREVENTION AND TREATMENT 201 



attention is necessary for several hours, when tlie extremities ina^^ be piled 

 in the center to complete burning. The placing of wood on top of the 

 carcass and addition of wood after the fire has started are unnecessary. 

 About one-quarter of a cord of wood is adequate, and where wood is 

 scarce, burning may be accomplished by using crude oil. Of course a 

 few sticks of wood beneath the carcass will help hold the heat but 

 this is not necessar3\ Ten to twenty-five gallons of crude petroleum are 

 sufficient. The odor from carcass burning is not very objectionable, 

 especially if the animal is destroyed soon after death. 



In cities it is usually feasible to have all large carcasses promptly

removed and effectually destroyed by commercial rendering and fertilizer 

 plants. These establishments should be subject to sanitary inspec- 

 tion. 



Carcass Burial. — Burial is generally unsatisfactory, especially if 

 bodies are well infested with maggots. We have found that at least 

 twenty-four inches of finely packed earth are necessary to prevent their 

 escape. The free use of quicklime on the body after it has been placed 

 in the grave helps to destroy the maggots and reduce chances of disease 

 spread. We have not yet undertaken experiments with the treatment of 

 carcasses before burial with creosote oil, but judging by results obtained 

 from treating those on the surface, this should be a good method of 

 destroying larvae, reducing odor and killing disease organisms.
