126 BOARD OF AGRICULTURE. [Pub. Doc. 



stable part is separate from the storage portion. There 

 should not be a cellar under the stable. The arrangement 

 of the animals should be the same as in stables where the 

 Sheringham valve system is employed (Fig. 8). 



Under the floor of the central driveway, running length- 

 wise of the building, there should be a space or chamber 

 having outside openings at the ends of the buildings. This 

 space should be about two or two and one-half feet in depth, 

 of the same Avidth as the driveway floor above. The open- 

 ings at the end may be of any convenient size, preferably not 

 smaller than six feet in length by one foot in width (Fig. 9). 

 The open space under the central section, which serves as 

 a fresh-air chamber, must be completely separated from the 

 two side spaces under the stall floors. 

 Fresh air from the air chamber is taken 

 into the stable through the manger 

 fronts, which are built in the form of 

 boxes, there being an opening at the 

 bottom into the fresh-air chamber, and 

 another at the top into the stable (Fig.

du'ectly m iront oi the occupants, at 

 the point where it is most needed (Fig. 11). From contact 

 with the animals it becomes heated, rises, and, with the im- 

 purities that it has received from the animals, escapes through 

 the outlets above. 



This system possesses the advantage of being quite auto- 

 matic. The air is brought in through numerous small open- 

 ings, preventing uncomfortable draughts. It is introduced 

 at just that point where it is most needed, and, again, each 

 animal gets its supply of fresh air regardless of its position 

 in the stable. 



In the construction of new or in the remodelling of old 

 stables to improve the sanitary conditions about them, more 

 especially to provide for eftective ventilation, one or a com- 

 bination of two or more of the systems mentioned in the 

 foregoing pages may be employed. As to which system is , 

 introduced, must necessarily depend largely upon existing 

 conditions.
