BUILDING THE SILO. 93 



trouble tkat many others have had, from the 

 moisture getting between the two sheetings, sat- 

 urating the paper and thus holding the moist- 

 ure to such an extent that it started decay and 

 resulted in the walls becoming useless in a few 

 years. I used paper on the walls three years as 

 we filled the silos. This was done for the pur-

 at the end of ten years I was compelled to tear 

 out the partitions and put in circular cemented 

 silos in place of the square wooden ones. 



If I were to build more wooden silos I would 

 not make any double wooden walls on the inside 

 next to the silage, for the moisture will get 

 through the joints and fail to dry out, and will 

 surely cause decay in a few years. If one thinks 

 he must use lumber in some form on the inside 

 let it be of a good sound quality (sound knots 

 aire no objection) thoroughly dried and not 

 wider than four inches. Three inches in width 

 is better, as in case of shrinkage there is less 

 danger of the joints opening and letting the air

The Cemented Silo. — ^My first experience with 

 the cemented' silo was ten years ago, when I 

 built three. These proved so satisfactory that 

 I shall build no other kind hereafter, at least 

 until it is demonstrated that there is- something 

 better than the wooden cemented silo. When I 

 devised this style of silo I did not know that any
