SHELTER FOR SHEEP SUMMER AND WINTER 349 



such a box chute is 24 x 37 inches, and it should have 

 a ladder within attached to one side. The doors may be 

 24 inches long and 18 inches broad. The floor consists of 

 two thicknesses of brick laid in cement. 



The root cellar is 16 feet in diameter. Its location 

 and form will be readily apparent from the plan. The wall 

 is of bricks laid in mortar. In no part does the wall come 

 nearer on the inside than 3 feet 8 inches from the outer 

 walls of the building, that the frost may be the more 

 easily excluded. The window spaces, which are also used 

 as chutes for admitting the roots, have triple thickness 

 of glass in the form of a double window without and a 

 single one within. The floor overhead is ceiled, first, with 

 shiplap ; second, with two thicknesses of tarred paper ; 

 third, with furring to make an air space ; and fourth, with 

 shiplap. The door which opens into the feed room at the 

 head of the stair has also two thicknesses of boards, with 

 tarred paper and airspace. Fig. 19 gives an outside view 

 of the structure. 



The yards extend out 18 feet from the building on 

 either side, and they are separated from one another by 

 movable divisions. A less width than 18 feet, as, for in- 

 stance, 12 or 14 feet, would make the moving of the 

 partitions much easier. They extend from the shed to 

 the fence that hems in the yard.
