 would be filled, lowered, unhooked, and rolled 

 into either barn, so lightening the work. 



When finished, the entire cost of silo and 

 roof was $154, a sum which can be reduced 

 considerably if only an individual roof is used, 

 which can be made in the conical form with 

 little difficulty, if the silo is not more than 15 

 feet in diameter; for no rafters need be used, 

 and only a single circle, like the one in the 

 center of the sketch, which is made of 2-inch 

 stuff cut in sections, in the form of a circle, 

 and two layers spiked together, breaking 

 joints. 



The roof boards are put on by nailing them
