HOW TO BUILD A SILO. 



as would be likely to occur in case of wooden laths. 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 she ting, 

 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 sufficient. The Gurler must be cement lined, how-
