that price, and iron rods and jack-screws would 

 cost about $62.50. The boxes would last 31 

 years, or $2.00 a year; the barrels, 3 years, or 

 $10.00 a year; the screws and rods, 70 years, 

 or, say, $1.00 a year. But the time, accuracy, 

 and convenience of the screws w r ould more 

 than double the economy of the boxes or 

 barrels, and should be reckoned at only 50 

 cents a year. I esteem the value of the rods, 

 for strength and security, fully equal to their 

 value in pressing the forage; and, if I were 

 building a cheap wooden silo, I should put 

 them in, first building a good 1 8-inch cement 

 wall, 3 feet high, upon a good foundation, well 

 drained, setting my wood silo upon it, putting 

 a timber between each rod and the inside 

 double boarding, with 2 x 12 inch studding, 

 filled around the bottom with cement and 

 gravel, and between the out and inside board- 

 ing with sawdust to keep out the frost. I 

 would also spike 2-inch plank firmly around 

 the outside, at the top, middle, and bottom, 

 because you want to be sure of your 8 or 10 

 months' food for your cattle, and silos are so 

 difficult and expensive to repair, if the walls 

 give way. Built in this way, wooden silos are 

 easily converted into cement ones, which are 

 sure to be wanted in the future, and are always 

 permanent and require no repairs.
