 eaves. 



Two rows of plate-glass roof-lights should run 

 along either side of the roof at intervals of six feet 



apart. They should not be placed 

 opposite each other. Those on the 

 north side should be placed inter- 

 mediate between those on the south 

 side, both vertically and horizon- 

 tally, and by this arrangement a 

 properly-diffused light will be ob- 

 tained all over the interior of the 

 stable. In stables where the roofs 

 slope at the ends, the same system 

 of roof-lights should be observed ; 

 but if the gables run up perpen- 

 dicular to the top, hinged sash- 

 lights may be let in all along the 

 gable ends at a good height from 

 the ground, in addition to the win- 

 dows already described. (Fig. 45.) 

 Of course, the antiquated sys- 

 tem of lofting in stables must be 

 entirely abolished, as it prevents 

 both lighting and ventilation ; and 

 hay lying above horses in a loft for 

 any length of time becomes very un- 

 wholesome by the vitiated air emitted from the horses 

 constantly passing through it. Stables with more than 

 six stalls should have two entrance doors, not neces-
