ABOUT STABLES. 



permitted. Ventilators that reach to within twelve inches of 



the floor and extend through the roof will regulate this. 

 The accompanying illustration shows a convenient and 



easily made ventilator for barn or stable. It is a square box 



\ \\V reaching from near the floor up and out through 

 7(M ~ the roof. The bottom is open, but closes with a 

 If-iy slide. Near the ceiling is a hinged door con- 



trolled by a cord, as shown. In warm weather 

 this upper door can be opened to let out the 

 heated air, which always rises. In cold weather 

 this door can be closed, and the slide at the 



bottom opened to remove the foul gases that, from their 



greater weight than air, sink to the floor. The draft up 



through this ventilator will remove them. 



Too often the chutes which bring down hay and oats are 



the only ventilation in a stable. They 



may be a source of much discomfort if not 



danger to the horse. Such chutes should 



be fitted with cross boards for sliding in, 



to close them tightly at top or bottom to 



stop air currents. 



Hay or straw chutes may well serve as 



ventilators if they be closed always, where ^^ 



the hay is put in directly after using, and 



if they are carried up to the roof. A ven- 

 tilator so arranged is here illustrated. The 



bottom should be two feet from the entry 



floor. It contains near the stable ceiling 



a hinged door, opened and shut by a cord, 



and near the top of the building a damper 



to close in case of high winds. The 



damper is shown closed, as for a night of 



high winds. To open it pull the cord and wind it about the
