These bottom governors can be arranged to 

 have the outlets on a level with the bottom of 

 the silo, by cementing a pipe in the wall large 

 enough to sleeve the governor into. The stop- 

 cock, from the drip pipe in my silo, comes out 

 over a little well about three feet deep, to per- 

 mit a pail to be held to catch the juice. All 

 the governors, except those lying directly upon 

 the bottom of the silo, have the perpendicular 

 pipes come up through the forage. All the 

 horizontal pipes should be placed upon strips 

 of board about 4 inches wide. All the gov- 

 ernors should be carefully put in, so that the 

 ^4-inch holes will be at the bottom, which 

 makes a passage the whole length of the frame 

 for air and gas to get into the pipes. In put- 

 ting in the centre governor, the forage should 

 be well trodden level, or it will get out of place, 

 and the pipes bent in settling. 



Sometimes, in old silos, when people don't 

 want to go to the trouble and expense of 

 making alterations, I put in both of the 

 perpendicular pipes from the governors, to 

 come up through the forage to the top, in 

 which case, if there is much juice in the bot- 

 tom, it must be pumped out before cutting 

 down the forage into it, because air coming 

 in contact with the juice is apt to change
