Lice on cattle can be destroyed by washing witb a solution of 1 lb. 

 tar-soap in 7 U.S. gals, of water, or with various proprietary prepara- 

 tions. This should be done in the evening after milking in the case of 

 milch cows. 



The house-fly [Musca domestica, L.] is best controlled by attention 

 to manure heaps, which should be stored in dark places and spread out 

 once a week and treated with borax or hellebore. Powdered borax 

 should be used at the rate of | lb. to 8 bushels of manure and 2 or 3 

 U.S. gals, of water then poured over the heap. Hellebore should be 

 applied as a solution made by mixing | lb. hellebore with 10 U.S. gals, 

 water. 



Chicken lice and mites may be controlled by keeping fowl-houses 

 clean by spraying all cracks and crevices with lime-sulphur wash, 

 kerosene, whitewash or crude carbolic acid, and by painting all nests 

 and roosts annually with some wood preservative. Sitting hens may 

 be dusted two or three times a week with insect powder, and the 

 heads of young chicks treated with lard or sweet oil, or with 1 part 

 blue ointment mixed with 5 parts of vaseline or lard.

In no case has the house-fly [Mnsca domestica , L.] been proved to 

 be exclusively the specific carrier of any particular disease, though it is 

 generally the most effective. Neither is it known to be the intermediate 

 host of any disease-causing organism occurring in man, though it is 

 the true intermediate host of Habronema muscae infesting horses. 

 Observations on flies from houses in which cases of dysentery or 

 diarrhoea were present have shown that under experimental conditions 

 flies can readily carry and disseminate certain pathogenic organisms, 

 which they also do under natural conditions, especially during out- 

 breaks of infectious diseases. Organisms producing bacillary enteritis 

 may often be met with in flies under natural conditions.
