THE "WISCONSIN" SILO. 47 



costs more than other kinds of wooden circular silos, especially 

 more than the stave silo soon to be described; but once built 

 needs but little attention and it is durable and economical; being 

 practically air-tight, the losses of food materials in the siloed 

 fodder are reduced to a minimum. 



Modifications of the Wisconsin Silo. 



Several modifications of the Wisconsin Silo have been proposed 

 and have given good satisfaction; one is described by Prof. 

 Plumb in Purdue Experiment Station Bulletin No. 91, as follows: 



The studs are 18 inches apart, and for about half way up there 

 are three layers of sheeting against the studs with tarred paper 

 between. The upper half of the studs has but two layers of 

 sheeting. The sheeting was made by taking 2x6 -inch white pine 

 planks and sawing to make four boards. The silo rests on a 

 stone wall 18 inches deep and 16 inches wide. It is 30 feet high, 

 18 feet 4 inches inside diameter, and holds about 150 tons. An 

 inexpensive but durable roof was placed upon it. The cost of 

 this structure is as follows: As the work was all done by the 

 regular farm help at odd hours, the item of labor is given at 

 estimated cost: Studding, $13.03; sheeting, $63.00; 5 rolls of 

 paper, $6.25; nails, $2.40; cement for wall, $2.40; labor, $20.00; 

 total, $107.08. The owner of the silo was so pleased with the 

 service this one had rendered since its construction, that he built 

 another like it during the summer of 1902. This silo is connected 

 by a covered passage and chute with the feeding floor of the 

 cattle barn. 



The construction of this type of silo calls for as much care 

 in putting on sheeting, making doors and keeping out the air at 

 these places and at the foundation, as is required with the more 

 expensive forms previously described. The need for outer siding 

 will depend in a large measure on circumstances. The farmer 

 building the silo (living in Central Indiana) has had no trouble 

 with his silage freezing. In Northern Indiana the siding would 

 naturally be more necessary than in the southern part of this 

 state, but generally speaking, siding is not necessary, although it 

 does materially add to the attractiveness of the silo. 



Plastered Bound Wooden Silos. 



Plastered round wooden silos have met with favor among 

 farmers who have tried them, and are preferred by many for
