BRICK LINED SILOS. 81 



similar material as that used for inside sheeting may be 

 used. If built inside of a barn or in a sheltered place, no 

 outside sheeting would be required, although it would add 

 greatly to the looks of the silo. Not being certain that the 

 inside sheeting, laths and cement offered sufficient resist- 

 ance to the outward pressure in the silo, Mr. Gurler put 

 on wooden hoops outside of the studding, of the same 

 material as for the inside sheeting, putting it on double 

 thickness and breaking joints. The silo described, which 

 would hold 250-300 tons, . cost $300, without a roof. Mr. 

 Gurler considers this silo the best that can be built, and 

 estimates that it will last for at least fifty years, if given 

 a wash of cement every three years and if any cracks that 

 may start be filled before the silo is filled again. 



Brick Lined Silos. 



As an illustration of silos of this type we give below 

 a description of the silo built in connection with the 

 Dairy Barn of the Wisconsin Experiment Station; the ac- 

 companying figures, 11 and 12, will show the exterior ap- 

 pearance of the barn and silo, and a plan of the eastern 

 half of the first floor of this barn. 



The silo is circular in form, 18 feet inside diameter 

 and 33 feet deep. It is a framed structure lined inside and 

 outside with brick. On 2x6-inch uprights, two wrappings 

 of %-inch stuff, 6 inches wide, are put, breaking joints, 

 with no paper between. Brick is laid tight against this 

 lining, and on the brick surface is a heavy coating of 

 Portland cement (1 part cement, 1 part sand). On the 

 outside brick is laid up against the lining with a small 

 open space between (about % inch). The silo is filled 

 from the third floor of the barn, the loads of corn being 

 hauled directly onto this floor over the trestle shown to 

 the right in Fig. 11, and there run through the feed cut- 

 ter. When the silage is taken out for feeding, it falls 1 

 through a box chute to the main floor where it is received 

 into a truck (Fig. 30) in which it is conveyed to the 

 mangers of the animals.
