50 HOW TO BUILD A SILO. 



as- would be likely to occur in case of wooden latlis. For outside 

 sheeting similar material to that used for inside sheeting may 

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

 side 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 resistance 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 de- 

 scribed, 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. 



The Gurler silo uses much less lumber than the Wisconsin or 

 King silo, one thickness of sheeting instead of four or five thick- 

 nesses being suflScient. The Gurler must be cement lined, how- 

 ever, but it is cheaper as to first cost and is the more durable. 

 It was designed primarily for use inside some other building, 

 whereas the Wisconsin silo is intended to stand outside. 



Brick Lined Silos. 



As an illustration of silos of this type we give below a de- 

 scription of the silo built in connection with the Dairy Barn o£ 

 the Wisconsin Experimental Station; the accompanying figures, 

 12 and 13, will show the exterior appearance 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 bam, the loads of corn being hauled directly 

 onto this floor over the trestle shown to the right in Fig. 12, and 

 there run through the feed cutter. When the silage is taken out 

 for feeding, it falls through a box chute to the main floor where It 

 is received into a truck (Fig. 54) in which it is conveyed to the 

 mangers of the animals.
