When the freshly cut corn is placed in the 

 silo, it has not yet had time to become much 

 wilted, if, indeed, it is wilted at all. Conse-

 it there, is in a much freer condition than it is 

 after it has wilted ; for through the operation 

 of wilting the said air becomes much more in- 

 timately associated with it, and much more 

 difficult to separate from it. Therefore, dur- 

 ing the process of filling the silo containing 

 my apparatus, a large portion of the air in 

 contact with the forage will be taken into 

 the pipes a a, and escape into the surround- 

 ing atmosphere through the vertical pipes g 

 and m. 



The parts of the governor are now made to 

 be screwed together, which is found to be pref- 

 erable to " sleeving " them together, as was 

 formerly done. Right-hand screws are used 

 at every joint, excepting the right and left 

 couplings at the cross-sections. 



* We take the perpendicular pipes from any 

 part of the governors. When used to take 

 temperature, they are taken up through the 

 centre of the silo. The cut in Figure 2 repre- 

 sents a pipe taken up at one side, about 6 

 inches from the wall. 



In opening the silo to remove the forage,
