DRAINAGE.

The size should be about two feet square. The additional cost is 

 very trifling when it is considered that no other openings need be 

 provided for the admission of air. 



DRAINAGE AND WATER SUPPLY. 



Next in importance to the choice of the situation and aspect, 

 IS the method to be adopted in draining the stable. The former 

 cannot well be altered, but the latter may, and therefore I have 

 placed it second. To ensure the perfect performance of the office 

 of cleansing the stable, the first thing to be done is to provide a 

 means of receiving the liquid which constantly must fall upon the 

 flooring, consisting partly of the urine of the horses, and partly 

 of the water used in keeping them clean. Several plans are adopted 

 for this purpose, some of which are founded upon true principles 

 of economy, while others are wasteful in the extreme. In towns 

 and cities provided with sewers and water pipes, liquid manure is 

 seldom worth the cost of removing it, and hence in them there is 

 no choice, and the whole of the liquids flowing through the drains 

 must pass ofi" into the common sewers. Even here, however, a 

 catch pit should be provided somewhere outside the stable, without 

 which the traps will either become clogged if made gas-tight, or 

 they will admit the foul emanations from the common sewer if 

 they are so arranged as to allow of the free flow of drainage from 

 the stable into them. Such a pit as that represented below will

 once a week by the groom there will never be an overflow, while 

 in no case can any gas pass through it from the sewers. It is 

 merely a square pit lined with brick or stone and cemented. The 

 size must depend on the number of horses, but if made on the cal-
