themselves with a galvanised garbage can with a close- 

 fitting lid, and an inspector should see that this regulation 

 is carried out, and that the cans are in good working order. 

 Manure in a somewhat similar manner may be collected 

 preparatory to removal. For a one-horse stable a large 

 galvanised garbage can or tub with close-fitting lid is 

 sufficient. 



In large stables the difficulty can be met by constructing 

 a bin of concrete or thick wood, with a hinged top, and 

 another hinged door or flap at the lower part of the back, 

 from which the manure may be removed. Another plan 

 is to build a fly-proof lean-to shed communicating with 

 the stable by a screened door, and another door on the 

 outer side for the removal of the manure. 



In the absence of manure, garbage, or rotting carcases 

 of animals, flies resort to the tubs in privies if such are 

 available, and after wallowing in the filth, lay their eggs 

 in it and fly off and into the nearest house. 



Fly maggots may be destroyed in privy buckets, and 

 flies kept at a distance, by pouring an ounce of paraffin 

 into the bucket twice weekly. Chloride of lime dusted 

 into the bucket once daily is also effective. The lime 

 could be kept in a tin with a perforated top. Any other 

 strong disinfectant will answer the purpose, such as a 

 solution of sheep-dip or carbolic acid. 



In South Africa the privy accommodation is, as a general 

 rule, frightfully crude, constituting an ever-present danger 

 to the health and lives of the community. The result of 

 this neglect is that flies breed freely in the stercus. These 

 flies subsequently infect the house and neighbourhood, 

 sowing the seeds of disease and death broadcast. Even
