THE "WISCONSIN" SILO. 



47 



interior diameter of the silo, are placed on the foundation bedded 

 in asphalt or cemented mortar, and on this the studding is 

 erected, using two by fours, placed 15 or 16 inches apart. Inside 

 sheeting was secured by having 6-inch fencing re- sawed, making 

 the material a little less than %-inch thick. On this was nailed 

 laths made from the same material, the laths being made with 

 beveled edges so that when nailed onto the sheeting horizontally, 

 the same way as the sheeting is put on, there are dove-tailed 

 joints between the laths to receive the cement, preventing its 

 loosening until it is broken. The patent grooved lath might be 

 used, but they cannot be sprung to a twenty-foot circle. Better 

 than either kind of wooden laths, however, is wire netting or 

 metal lath of one form or another, such as is now generally used 

 in outside plastering of houses, nailed on strips of Ix2's which are 

 placed 15 inches apart, and nailed onto the studding through the 

 sheeting. Metal lath will not take up moisture from the silage 

 juices, and thus expand and possibly cause the plaster to crack,
