70 HOW TO BUILD A SILO. 



100 tons, which is the approximate capacity of a round silo of 

 the dimensions given. 



Connecting Round Silos with Barn. — The location of the silo 

 with reference to other farm buildings has already been dis- 

 cussed. The silo must be easy to get at from the stable, and 

 the silage, if possible, handled only once in being placed before 

 the stock. A round silo is most conveniently built just outside 

 of the barn and connected with this by means of covered pas- 

 sageway. The method of joining silos to barns is illustrated in 

 numerous pictures of silos given in this book. 



Details concerning the construction of stone, brick, and ce- 

 ment silos are given in Prof. WoU's "Book bn Silage," and in 

 .Bulletin No. 83 of Wisconsin Experiment Station by Prof. 

 King, as well as in numerous other pamphlets, and we shall 

 not take up further space here with the discussion thereof. The 

 same holds true with all other forms of silo construction than 

 those already explained. We wish to briefly mention, however, 

 the octagonal type of silo. 



Octagonal Silos. 



A number of octagonal silos have been built. In recent years, 

 and find favor with their owners in most instances. If properly 

 put up and care taken to fasten the girts securely at the corners 

 with plenty of spikes, the octagonal silo is greatly superior to 

 the_ square type, and has nearly every advantage of the round 

 silo, and can readily be constructed by anyone handy with tools 

 with the assistance of the ordinary farm help. 



The foundation should be of stone or brick as described for 

 various other forms of silos, and should be laid out with proper 

 dimensions for the size decided upon. Brief details are here 

 given for an octagonal silo of about the same capacity as a 

 round silo, 20 feet in diameteir and of equal height. 



If the foundation is laid out so that the corners are in the 

 circumference of a circle 21 feet in diameter the horizontal girts 

 will be about 8 feet long, ajid will be much stronger and better 

 able to withstand the lateral pressure than the sides of a 

 square silo of equal capacity. Details of construction are shown 

 in the drawings, Figs. 25 and 26. The girts should be Sx8 

 inches and spiked at the corners with 6-inch spikes, up to
