BUILDING CONSTRUCTION 177 



animals should be groomed and have their udders cleaned in the 

 general byre so that no dust is caused in the milking-shed. The 

 floor of the shed should be washed down with water before the 

 animals enter so as to keep down dust. The milking-shed should 

 be free from all unnecessary fittings, be hygienically constructed 

 and well lit and ventilated. It should not be placed in an exposed 

 and dusty position. 



Close to the milking-shed and connected to it by a passage (so 

 as to avoid dust) should be placed the Milk House. This must be 

 a cool, well-ventilated building, and the most careful attention 

 must be paid to details that will ensure that the place can be kept 

 clean and free from dust. The windows and all ventilating aper- 

 tures must be screened to keep out flies. The fittings installed 

 will depend upon the method of handling the milk, but in any case 

 there should be facility for cooling the milk. 



The Roof Truss of the cow-shed and milking-shed should be as 

 simple as possible so as to lodge the minimum amount of dust 

 (see section on Roofing). 



PIGGERIES. 



Pig houses range from the single pig-sty of the cottager to large 

 piggeries capable of housing some hundreds of pigs such as are 

 erected by those who make pig-keeping their business. 



The single pig-sty usually consists of a small covered-in pen 

 to which is attached a small open court or space a few feet square 

 in which is placed the food-trough. Larger piggeries are often 

 constructed on the same principle, that is to say, the pigs sleep in a 

 small covered-in space and pass out into an open unroofed part 

 to take their food. Other piggeries are entirely roofed, and may 

 or may not have an exercising yard outside the building. The dis- 

 advantages of the partly closed and partly open piggery are very 

 real. The animals lie huddled up in a space that is often too small 

 and unventilated while they rest and sleep, and have perforce to 

 pass out into the open air and often to stand in rain and snow to eat 

 their food. They suffer from extremes of temperature, and their 

 sleeping quarters as often as not are undrained and damp. Since 

 the desired object of housing animals is to keep them in an equable 

 temperature and to keep them dry, it is obvious that this method has 

 nothing to recommend it, and it is not to be confused with the 

 open-air system of pig-keeping which is an excellent method when 

 properly carried out. The outer court, therefore, should always 

 be roofed over, though it may be left open at one side to admit light
