SILO BUILDING. 



A. S. Kenyan, C.E., Engineer for Agriculture. 

 Since the publication of the specifications for the construction of a 

 ^o-ton silo in the Journal for February, 1906, some slight alterations 

 and modifications have been adopted. It is well, therefore, to publish 

 the specifications and quantities now being worked to. These are, of 

 ■course, not final. Many suggestions from esteemed correspondents have 

 been adopted and more will be welcomed. The use of a preservative 

 coating of tar or similar compounds on the inner face of the iron lining

 be employed in seeing that it is well and thickly put on. It is advisable 

 even to limewash as the silo is emptied to preserve the iron before refilling

 is also a question of careful work. None of the points laid stress upon 

 are unimportant. They are all the fruits of experience and have been 

 carefully thought out and tested before being recommended.
