SILOS, ENSILAGE AND SILAGE.

water tight in a thin bed of cement mortar, and spiked 

 to ribs of 2x4 scantling bedded in the concrete. 



The general plan of the doors is indicated in the dia- 

 gram, Fig. 8. The large door, B, in the gable to receive 

 the carrier from the cutting machine in filling, needs no 

 description. Similar doors on each side, above the walls 

 of the silo proper, will be found convenient for admitting 

 light when filling the silo, and at other times as required. 



They may be hinged at the 

 top and fastened at the bot- 

 tom with a hook and staple. 



The long door, A, in the 

 wall of the silo, to give access 

 to the silage in feeding out, 

 should be wide enough to 

 admit a truck (in the form 

 of an oblong box on three 

 wheels, two of them under 

 one end and one at the other), 

 and it should extend from the 

 sill to within two and one 

 half or three feet of the top 

 of the silo. 



This door is, in effect,

sheathing; with its middle layer of tarred roofing paper, 

 that can be removed in pieces, but which, when in place, 

 protects the silage as completely from atmospheric con- 

 taminations as any other portion of the walls. 



When setting the studs for the frame, place two of 

 the end studs the proper distance apart to form the 

 jambs of the doorway. On the outer side of each spike 

 a 2x4 inch scantling flush with the inner edge, to form a 

 wide bearing for the laps of the inside sheathing, and the 

 pieces cut from it to form the door. When putting on the 

 inside sheathing, cut from each board of the first layer,
