door on the main floor. From this driveway access is also had to the 

 second floor of the granary. When not otherwise in use this cross floor 

 is occupied by carts, wagons, etc. The main basement is also used for 

 the storage of implements and machinery. 



Inspection of the i^hotograph and plan will give an idea of the 

 arrangement of the cow stable, which is 135J by 43 ft., but there are 

 several features that should be specially mentioned. The roof is of 

 steel, under which is building paper and boards, then a G in. air space,. 

 then building paper and matched boards, then an inch and a half air 

 space and then lath and plaster. All the ceilings and the wall of the 

 monitor roof are of adamant cement, painted, and the walls of the 

 stable are of matched North Carolina pine sheathing, oiled. There is 

 no basement, and the cement passages and gutters are built ujion solid 

 earth and masonry. The gutters behind the cows incline toward the

center, where they empty into cisterns on either side of the building, 

 thus saving all the liquid manure. By making the floor of the sheds 

 at the south end 9 ft. below that of the stable it is convenient to carry 

 all the solid manure in barrows and dump into carts or manure spread- 

 ers for immediate distribution. The stalls, of which there are 65, are 

 fitted with a V-shaped cement feed and water trough, provided with 

 movable dividing frames to permit of thorough cleansing. 



Stanchions of various patterns are used in the stalls, but most of the 

 animals are fastened with the Walters tie, arranged so that each 

 animal maybe liberated separately or entire sections at once by a single 

 motion of the lever. 



The upper windows are hinged at the bottom and moved by Ormsby's 

 ventilating apparatus, the upper sashes of the lower windows beiug 

 hinged at the bottom and moved individually by transom lifts, and 

 the lower sashes are protected by iron gratings and slide into the par- 

 titions. Trapdoors, moved by cords and pulleys, are also placed in 

 the cupolas. This arrangement secures perfect ventilation without
