THE SUCCULENT ROUGHAGES

Manufacturing concerns have specialized in stave silo construc- 

 tion and in most cases the farmer can purchase such a silo to 

 better advantage, when length of life is considered, than he can 

 build himself. 



363. The wood- wrapped silo.— Using the stave type of con- 

 struction as a basis other silos have been designed with double or 

 triple walls. These silos are more durable, furnish more protection 

 against freezing, and, of course, withstand wind and weather to 

 better advantage. They cost more but are probably worth it. 



364. Masonry silos.— The 

 use of brick, concrete or hol- 

 low tile is increasing for silo 

 construction. These materials 

 make a much more permanent 

 silo but, of course, are con- 

 siderably more expensive and 

 many farmers cannot afford 

 to make such a large invest- 

 ment. Further, it may not be 

 profitable for them to do so. 

 Concrete is cheaper than brick 

 or hollow tile. 



In trying to decide what 

 kind of a silo to build, it will 

 help to look through the dairy 

 papers and send for literature 

 on the various ones advertised. 

 It would also be a good thing 

 to talk with neighbors who 

 have silos and with the Farm 

 Bureau Agent. 



365. Size of silo.— The 

 size of silo to be built will de- 

 pend on the size of the herd, 

 assuming, of course, that the 

 farmer can grow a sufficient Concrete Block Silo
