STABLES

within the building is a possible source of danger to the animals and 

 also to the men employed. 



Various methods may be adopted, according to the size of the stable. 

 In the case of a large one the separate channels in each stall or box run 

 into a long channel at the foot of 

 the stall, the outlet of which is at 

 either end of the stable. When 

 only two or three stalls or boxes 

 have to be provided for, the urine 

 may be conveyed from each by a 

 separate channel to the outside of

the stable; in fact, so long as the true principle is maintained, it is a 

 matter of indifference how the details are arranged. 



o 



The channels in the stables must be disconnected from the drains out- 

 side by being made to discharge over trapped gullies. The liquid passes 

 from the channel through a short 

 iron pipe built into the wall, and 

 it is a good plan to fit on the 

 outer end of this pipe a brass or 

 iron flap hinged at the top to 

 open outwards (fig. 473), so that, 

 while the liquid can run out 

 readily, the flap prevents to a 

 large extent the inlet of more or 

 less foul air. Two good forms of 

 gully are shown in figs. 474 and 

 475, one being of cast-iron and 

 the other of stoneware, and each 

 having a grating at the top and 

 a strainer below to retain solid matter. The stoneware gully has a side 

 inlet, to which the drain from a grid under a water-tap can be connected. 

 If the sewage is conveyed by the drains into a manure-tank, cesspool, or 

 public sewer, aerial communication between these and the drain must be 

 stopped by an intercepting trap, which is most conveniently placed in an 

 underground chamber or manhole provided with an air-tight cover. The
