board is raised when the privy is used and lowered into the liquid imme- 



diately after. 



The building for a L. R. S. privy differs in no essential respect from that 



described for the sanitary privy. 

 It should be fly-proof and well 

 ventilated. 



The effluent from a L. R. S. 

 privy is potentially dangerous 

 and must be disposed of where 

 it will not endanger the health 

 of man. If disposal by subsur- 

 face irrigation is not practicable, 

 the effluent tank can be emptied 

 at intervals and the contents 

 buried or poured into a sewer. 

 The effluent from a number of 

 L. R. S. privies such as those 

 shown in Plates 322 and 323 can 

 be conducted through water- 

 tight pipes to a central siphon 



chamber and hence tO a Subsur - 



face irrigation field or a small in- 

 termittent filter in the same man-
