Silo Construction in Nebraska 9 



The second type of silo is as strong as any stave silo and as 

 easily cared for, but is more trouble to order. The third type 

 should also have more convenient doors. 



SILO WOODS. 



Silos have not been in use long enough in Nebraska to warrant 

 the drawing of any definite conclusion as to lasting qualities. 

 Two white pine, homemade, plain, stave silos examined near 

 Omaha after having been used eight years were very badly de- 

 cayed at the lower ends of the staves. A elieap white pine silo 

 on the University Farm was practically rotted out at the end of 

 five years' use, while a better grade of white pine silo which has 

 been in use about eight and one-half years has just commenced 

 to decay at the lower ends of the staves and is apparently in good 

 condition above the first foot. 



Conclusions drawn from Bulletin No. 100, Iowa State College, 

 place the merits of woods fot silo use as follows : 



1, Redwood ; 2, Cypress ; 3, Oregon Fir ; 4, Tamarack ; 5, White 

 Pine; 6, Long-leaf Yellow Pine. 



ORDERING STAVE SILOS. 



The Manufactured Silo. In ordering a silo it must be borne 

 in mind that the custom of silo manufacturers is to sell only the 

 silo proper with the necessary anchor rods and also the rafters 

 for the roofs. Tn order to complete the silo, the following ma- 

 terials are needed : Silo floor, foundation wall, sheathing, roofing, 

 paint, and chute. 



THE HOMEMADE TONGUED AND GROOVED STAVE SILO. 



This silo needs all the material mentioned in the preceding 

 paragraph under ordering "The Manufactured Silo," and in addi- 

 tion needs the material for the silo proper with the anchors and 

 rafters. A silo 16 by 30 feet purchased in this way should not cost 

 more than |260.00 for the material used in the floor, foundation, 

 walls, and roof, including the paint. 



FOUNDATIONS. 



The foundation for a silo is an important part which is often 

 overlooked. It can be made of brick, clay blocks, concrete blocks, 

 or solid concrete. Probably the latter is as good as any of the 

 others and less difficult to handle. All foundations should go 

 below the frost line. 



If the foundation is to hold a masonry silo, it should have a 

 footing at least two feet wide and 18 inches deep, while if it sup-
