54 HOW TO BUILD A SILO. 



An illustration and description of the original round silo, witl 

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

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

 tions of a Aumber of other first-class round wooden silos will alsc 

 be found, like those constructed at the Experiment Stations ir 

 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 ol 

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

 past few years than any other silo type. 



Since their first introduction Stave Silos have been favorablj 

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

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

 periment Station, we find the stave silo spoken of as "the most 

 practical and successful silo which can be constructed," and the 

 Ottawa Experiment Station is on record for the following state- 

 ment in regard to the stave silo: "From extensive observatioB 

 and study of silos and silo construction, and from experience here 

 with a number of different silos, it would appear that the stave 

 silo is the form of cheap silos that for various reasons is most 

 worthy of recommendation. It combines simplicity and cheapness 

 of construction with the requisite conditions to preserve the 

 silage in the very best condition for feeding." 



Stave silos are, generally speaking, similar to large railroad 

 or fermentation tanks, and to make satisfactory silos should he 

 built as well as a No. 1 water tank. The first stave silos were 

 built in this country in the beginning, of the nineties; they soon 

 found some enthusiastic friends, while most people, includinf 

 nearly all writers and lecturers on silo construction, were in- 

 clined to be skeptical as to their practicability. It was objected 

 that the staves would expand so as to burst the hoops when the 

 silo was filled with green fodder; that they would shrink aftei! 

 having been left empty during the summer months, so that th^ 

 silo would fall to pieces, or at least so that it could not again 

 be made air-tight; and finally, that the silage would freeze liii 

 such silos, and its feeding value thereby be greatly lowered. U\ 

 addition to this, it was claimed that a substantial stave sl^ 

 would cost as much as a first class ordinary all- wood silo of the
