closely with small carpet tacks where they overlap, and if 

 this is done a lap of 2 inches will be sufficient. 



FIG. 207. D, Showing method of constructing the all-wood round silo 

 and connecting it with the wall flush with the outside. This figure 

 shows the most substantial form of construction with three layers 

 of half-inch lumber and two layers of three-ply acid and water 

 proof P. & B. paper between them. A very excellent silo is; made 

 after this plan omitting the inner layer of lining and paper and 

 the layer of paper on the outside. With small silos 15 feet in diam- 

 eter only the siding on the outside is necessary for strength and 

 protection against weather. E, Showing method of construction for 

 ventilating the spaces between the studding in all-wood and lathed 

 and plastered silos. The lower portion shows the intakes of fresh 

 air from the outside at the bottom, and the upper portion shows 

 where the air enters the silo at the plate to pass out at the ventilator 

 In tlie roof. 



Such a lining as this will be very durable because the 

 paper will keep all the lumber dry except the inner layer 

 of half-inch boards, and this will be kept wet by the paper 

 and silage until empty and then the small thickness of wood 

 will dry too quickly to permit rotting to set in. 



A still more substantial lining of the same type may be 

 secured by using two layers of paper between three layers 

 of boards, as represented in Fig. 207, and if the climate is
