 then upon a skeleton wooden frame we put 

 a second governor, in all respects like the

 outlet into the drip pipe, we turn it up, with 

 a perpendicular pipe coming up through the 

 forage from the centre of the pit and through 

 the plank covering, and terminating, like the 

 other, with a plug or cap. When the pit is 

 full and trod down evenly, cover with 2-inch 

 spruce planks fitted to slide down the walls 

 nicely and evenly; press it firmly enough to 

 get about 2 feet of juice in the bottom, and 

 in practical operation this is all that is re- 

 quired. But in this pit, which was made to 

 try any experiment and test any principle in 

 the direction of possibilities, or perfect preser-

 and the three governors were sleeved together, 

 having a continuous outlet from top to bot-

 432 outlets for gas and air from the forage 

 into the pipes, distributed evenly through the
