ENTOMOLOGY

::\lYIASIS-ITS PREYENTION AND TREATMENTattention is necessary for several hours, when the extremities may be piledin the center to complete burning. The placing of wood on top of thecarcass and addition of wood after the fire has started are unnecessary_About one-quarter of a cord of wood is adequate, and where wood isscarce, burning may be accomplished by using crude oil. Of course afew sticks of wood beneath the carcass will help hold the heat butthis is not necessary. Ten to twenty-five gallons of crude petroleum aresufficient. 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~OlPLATE XIV.-Trench prepared for burning carcass.(Bishopp.)removed and effectually destroyed by commercial rendering and fertilizerplants. These establishments should be subject to sanitary inspection.Carcass Burial.-Burial is generally unsatisfactory, especially ifbodies are well infested with maggots. We have found that at leasttwenty-four inches of finely packed earth are necessary to prevent theirescape. The free usc of quicklime on the body after it has been pl,acedin the grave helps to destroy the maggots and reduce chances of diseasespread. We have not yet undertaken experiments with the treatment ofcarcasses before burial with creosote oil, but judging by results obtainedfrom treating those on the surface, this should be a good method ofdestroying larvre, reducing odor and killing disease orgamsms.
