50 HOW TO BUILD A SILO. 



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 of 

 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 barn, 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 (Pig. 54) in which it is conveyed to the 

 mangers of the animals. 



An illustration and description of the original round silo, with 

 a capacity of 90 tons, built at the same Station in 1891, are given 

 in Prof. Woll's Book on Silage, where descriptions and illustra- 

 tions of a number of other first-class round wooden silos will also 

 be found, like those constructed at the Experiment Stations in 

 New Jersey, Missouri, and South Dakota. 



Stave Silos. 



The stave silo is the simplest type of separate silo buildings, 

 and partly for this reason, partly on account of its cheapness of 

 construction, more silos of this kind have been built during the 

 past few years than any other silo type. 



Since their first introduction Stave Silos have been favorably 

 mentioned by most writers on agricultural topics, as well as by 

 experiment station men. In the recent bulletin from Cornell Ex-
