[Exhibit E.] 



REPORT ON ENSILAGE. 



Silo. 



The silo, 10.5 by 14.1 feet, inside measure, and 11 feet 

 deep, for experiments with ensilage, has been made in one 

 corner of the feeding barn, and entirely above ground. 



In its construction the aim has been to secure a practically 

 air-tight box with the least possible expense. 



The lower two feet of the silo is enclosed with brick walls, 

 nearly two feet in thickness, which form on two sides the 

 foundation walls of the building, the earth on the outside 

 being graded nearly to the level of the sills. 



Above the brick work the walls of the silo are made with 

 six-inch studs, in contact with the sheathed and clapboarded 

 covering of the barn on two sides, and the inner walls are 

 covered with matched boards on the outside. The lining of 

 the silo consists of two thicknesses of one-inch matched 

 boards, nailed firmly to the studs, with sheets of tarred 

 paper between them to make the walls as nearly air-tight as 

 possible. In this way a dead-air space of six inches is 

 secured in the walls on all sides. 



Door. 



The door of the silo, opening on the barn floor, is made 

 of pieces of two-inch planks, planed to a thickness, and bat- 

 tened with a lining of one-inch planed boards. These pieces 

 forming the door are placed crosswise of the doorway, fitting 

 closely inside the jambs, with the inner surface flush with the 

 inside of the wall of the silo. The door is kept in place by 

 planed 2 by 4 scantling, fastened to the jambs of the doorway 

 with square-headed screw bolts, technically called " lag- 

 screws," to sustain the pressure of the ensilage on the 

 door.
