Describe a proper method of drainage for a stable. 



Stalls should not slope more than one-half inch toward their 

 centre, and a similar slope from before backward is sufficient. 

 A shallow gutter running back of the stalls should be conducted 

 outside and into a trap which empties into the sewer. All drains 

 within the stable should be on the surface to permit of ready access. 



What is the objection to building a stable (a) on a damp northern 

 slope, (b) in a deep, narrow, east and west slope, (c) on a 

 springy, hill-foot or on other wet impervious soil? 



(a) There would be insufficient sunlight to evaporate the objec- 

 tionable moisture. 



(b) There would be insufficient sunlight and a tendency to 

 dampness. 



(c) It would be difficult to secure proper drainage, and the 

 dampness would be detrimental to health. 



Mention some of the ways by which impure water may be purified or 

 made wholesome. 

 Sand filtration, sedimentation, and boiling. 



What precautions should be taken in grain feeding as regards watering 

 in connection with the grain?
