SECRETARY'S REPORT. 255 



The revolving cylinder is preferred by some of the most compe- 

 tent judges. 



Leaving this room, we pass on to the barn, the gable end of 

 which faces the stables. 



The ground floor of this building consists of: (1) mill room, 

 (2) steam-engine room, (3) corn barn, or room for storing, &c., 

 and which is 41^ by 21^- feet. On the second floor, 14 feet 

 from the first, are — (1) the threshing room (same dimensions 

 as corn room ;) (2) dressing room, 21 feet 6 inches by 17 feet 

 9 inches, containing two fixed winnowing machines. This 

 apartment is over the engine and mill rooms. As the grain 

 leaves the last fanners it enters an opening, descending to 

 within a few feet of the ground floor, and is received into bags. 

 So that, from the time of putting the sheaf into the threshing 

 machine till it is bagged, there is no intermediate manual labor. 

 The hopper of the mill is in the corner of this apartment, so 

 that the grain is easily transferred thither when required. 



The steam-engine is eight horse power, but capable of being 

 worked to ten. It is a high pressure engine, and has a vertical 

 cylinder with an eccentric for pumping water into the boiler, 

 the whole being firmly fixed on a solid floor of granite. The 

 crank attached to the piston turns an axle, on which, at a few 

 inches from the crank, a fly-wheel weighing one ton is attached, 

 and which passes through the wall into the " corn " room, 

 where motion is obtained from a double pulley on this axle, by 

 means of belts. One belt is carried up to the threshing floor, 

 for communicating motion to the threshing and winnowing 

 machines. Another belt runs flush with this wall to another 

 pulley, attached to an axle going through the same wall, for 

 driving a " bevelled " wheel, which communicates motion to 

 two shafts, passing in opposite directions — one to tlie chaff room 

 and steam shed, the other running up to the liquid manure 

 propeller and dairy. The threshing mill is on the Scotch prin- 

 ciple, and absorbs four horse power. It has a covered drum 

 with projecting edges as beaters. There is only one shaker, 

 consisting of a revolving cylinder carrying spikes. The straw 

 falls on an inclined plane, and is stored in an adjoining covered 

 shed, opening to the east. 



The threshed grain falls down to the first winnowing machine, 

 which blows the chaff" into a small apartment adjoining the straw
