Preserving Green Forage 145 



%-inch holes on the under sides, every 6 

 inches, were placed one at the bottom, one in 

 the centre, and one on the top of this mass 

 of corn, with outlets at the bottom and top, 

 closed with stop-cocks and plugs. These 

 governors were sleeved together, and so ar- 

 ranged that the corn could not stop the %- 

 inch holes, but would leave a continuous 

 passage under the pipes for the air and gases 

 to get into the pipes and be conveyed through 

 the pipes to the outside through the openings 

 at top and bottom, thus leaving an air-hole 

 within 3 to 4 feet of every part of the forage. 

 It is not usual to get any juice from the corn 

 in making ensilage, even with 200 pounds 

 weighting to the square foot; but, with this 

 device, the action was so prompt and decided 

 that I had 2 to 3 inches of juice from the corn 

 all over the bottom of the silo before it was 

 three-quarters full, and some days before it was 

 covered. I took the temperature daily at dif- 

 ferent depths, in the centre, which was never 

 over 72 in any part of the silo. This was 

 about the temperature outside when we com- 

 menced filling. Six feet from the bottom, the 

 mercury stood 56 to 58, which is above the 

 highest temperature we now have, four months 

 after filling. The forage does not heat up
