The colamn " Number on Counter" shows the number of revolutions the 

 steam-engine made during each experiment ; and that number being divided 

 by 115 (the number of revolutions the engine made per minute), the quotient 

 represents the time taken in the experiment. 



Class No. 2. 



Minutes. Horses. 



Garrett's prize machine 5-9x4 = 23-G horses to thrash 100 sheaves in 



one minute. 



Carpenter's . . , 10*7 X 4 = 42' 8 horses to do the work in the same 



time. 



The machines intended to be worked by steam-power, by Garrett and some 

 others, were generally very good in their mechanical details ; the arrange- 

 ment of Messrs. Hornsby, of introducing a screw-elevator, enables them to 

 keep their machines nearly as low in height as the ordinary machines, and the 

 contrivance that enables them to pass all the refuse in the adverse direction to 

 the cleaned corn is a great advantage. 



In the machinery exhibited by Clayton and Co. there were many useful 

 novelties. The performance of the various machines under trial, and the 

 excellence of their workmanship, rendered the experiments more interesting 

 on this than on any previous occasion. 



The difference in the power required for working these machines, taking 

 generally the extreme cases, was as follows : — 



Class No. 3. 



Minutes. Horses. 



Clayton, Shuttleworth, and Co., 



two prize machines ... 8*2 x 6 = 49* 2 horses to thrash ICQ sheaves 



in one minute. 



Smith's .»»..,. 11*6 X 5 = 58 horses to do the work in same 



time. 



In winnowing-raachines Hornsby and Son took the prize for their truly 

 useful and effective implement. It is worth their consideration to inquire 

 whether they should not make the machine something less in size : the time 

 is fast approaching when the thrashing-machines generally will chaff their 

 corn ; and as the machine in its present form dresses the corn faster than it 

 can be measured up, in the general way, a reduction in size might probably 

 be an advantage ; it would decidedly lessen the power required to turn the 

 machine, which is now rather too heavy. 



The chaff-cutting machine by Richmond and Chandler, for which they 

 received the prize, is a highly ingenious and effective implement ; it might 

 probably be improved by raising the spindle a little, as the knives would then 

 press upon the straw more flatly and not so much against the sides of the box 

 as at present : the power required to work it is extremely light, when used 

 for horse and steam power, and where the motion is continuous ; but the two- 

 pinioned machine by Cornes of Nantwich is the best machine for working by 

 hand. 



Several grinding-mills were exhibited, and the Judges' Reports show that 

 the metal mill of Hurwood, the prize implement, did its work very well and 

 with little power, and where the produce does not require reducing to flour it 

 appears to be preferable to stones. Hence for splitting beans, or grinding 

 any kind of grain for cattle or pigs, it is a very useful implement ; but for 

 grinding wheat, or reducing any kind of grain to very fine meal, stones would 

 do better, while linseed, oats for horses, and malt are, perhaps, better crushed, 

 without mealing, by rollers, as in Stanley's mill. Most of the metal mills do 

 not feed so readily as could be desired, and a more regular feed would be given
