310 CATTLE-BREEDING. 



opening in the center of the stable directly 

 above the track, either by means of a chute or 

 by being simply dumped from above. The 

 stalls all open out upon a drive-way formed 

 by a continuation of the roof outward, which is 

 further continued until it forms another row 

 of low stalls, used for calves, which also open 

 on this drive-way and are boxed in on the rear. 

 The drive-ways are left open ordinarily in 

 summer, but the ends are closed in the winter 

 and in stormy weather by large doors, which 

 effectually shut out storms and sufficiently close 

 the building against cold. As stated, the stalls 

 open on the drive- ways, which form great reser- 

 voirs of fresh air, and in order to take advan- 

 tage of this a space of about eighteen inches is 

 left in the doorway between the top of the door 

 and the joist above. This insures ventilation 

 as the doors do not fit closely below and avoids 

 draughts. Even in warm weather these, spaces 

 afford quite sufficient fresh air for respiration 

 even when the doors are kept closed for long 

 periods together, and they are so arranged that 

 by simply opening them for a few moments the 

 bad air is quickly expelled and the fund of pure 

 air thoroughly renewed. While no special 

 effort is needed in Kentucky to make this 

 building very tight, it can be made so with 

 little trouble, as it has a comparatively small 

 proportion of outside walls and few corners,
