creating an adverse current ; or a central extraction shaft may 

 be used, connected with openings in the walls, to flues between 

 the floors, or immediately under the ceiling, and terminating 

 above the roof, with an induced up-current cowl. 



Defective vision, weakness of the sight, and (notwithstanding 

 the ignorant belief that horses put on flesh in darkened stables) 

 injury to health, and neglected sanitation, are the usual con- 

 sequences of the absence of light. By the use, therefore, of 

 glazed ventilators, as shown on Fig. 39, and on Plates 3, 8, and 

 9, the double purpose of lighting and ventilating the stable may 

 be accomplished. 



Where stables are lighted from the roof, by swing sashes or 

 other means, Sheringham's ventilators, illustrated by Fig. 40,

are most frequently used. They are made of galvanised iron, 

 and fitted with brass pulley, line, and balance weight, and an 

 .external grating for the admission of air, 13 J inches by 6 inches ; 

 but the principle of their construction can be applied to any 

 opening. 



Loose boxes should be ceiled on the underside of the rafters, 

 if used for infirmaries, and are improved by a separate louvre 

 ventilator to each roof, as shown on Plate 3. 



From 1500 to 2000 cubic feet of air per horse are required 

 for loose boxes of this kind, as the fresh air is not so freely 

 or so frequently admitted as in a stall. 



In the series of designs of " private stables," the various 

 methods of ventilation which the Author has ventured to 

 advocate in this chapter, are illustrated, many of them having 

 been carried into most successful operation.
