WINDOWS. 51 



containing two rows of horses, and about 10 inches in single- 

 row stables. The side boards, 12 to 9 inches broad, should 

 overlap each other, but leaving an interval between of about 

 3 inches, their angle being from 45 to 60 degrees, according to 

 the exposure of the stable. 



Instead of side-boards, swing-windows are sometimes 

 introduced, these opening at an angle from the inside of the 

 stable; and, when it is desired to have the stable well 

 lighted, glass is preferable. Sometimes the roof of .the louvre 

 board itself is of glass, which certainly gives abundance of 

 light, though it makes the stable hot in summer. 



Inlets for the air should be near the floor of the stable, as 

 it tends to dry this, and also because it has a tendency to 

 ascend towards the nostrils. It should not be allowed to 

 enter beneath the manger, unless the current is broken or 

 diffused previously, as it will chill the horse's legs when 

 he is standing, and his body when lying down. This break in 

 the current can easily be effected by laying the outer course of 

 perforated bricks at either a lower or a higher level than the 

 inner one. It is best, however, to have the air enter if it 

 must enter through the front (or manger) wall between the 

 stalls, as then it will not impinge directly on the horses. But 

 there is no absolute necessity for having the air enter only on 

 one side, or even in any special part of the stable, so long as 

 there is an abundance without draughts. 



WINDOWS. 



Windows are chiefly intended for light, but they also assist 

 in ventilation. For the latter purpose, unless reliance can be 

 placed upon the stable men, they are not so valuable ; though 

 in hot weather, and when it is required to freely air stables, it 

 is very advantageous to have them thrown open. They may 

 either move on a pivot at the middle of each side or be
