FARM DAIRYING 



a cement wash when the acid of the silage has af- 

 fected the Inside walls. 



I quote from the Ontario Farmers' Institute 

 Report, 1 9 10: 



"My silo is built of cement from bottom to top. We 

 dug a trench 2j4 feet wide and down to hard soil. We 

 used cement mortar and large stones to make a founda- 

 tion, having it level at top of ground so as to set our steel 

 rings on level. The size of my silo is : 40 feet high and 



14 feet across inside. The walls are 9 inches at bottom 

 and 6 inches at top. The material required to build this 

 silo was 50 barrels of cement and 50 yards of fine gravel, 

 using no stones above the ground. It is reinforced every 



15 inches with a wire rope made of four strands of No. 9 

 wire twisted together and placed in centre of cement. 

 Eight bolts were placed in top of silo to bolt the rafters 

 to, and thus save making a wooden circle for rafters. 

 The cost of material is as follows : — 



50 barrels of best cement, at $1.45 

 50 yards of clean gravel, at 15c 

 400 lbs. wire

The builder found all necessary scaffold and rope. It 

 takes three men about nine days to complete a silo if the 

 weather is fine.
