Cultivation of Arable Land. ThreJIiing of Grain By the Machine. 297 



liend it will be performed, on an average of different forts of grain and different 

 (fates of them, at one-third the expenfe of the flail method, or, perhaps, much 

 lefs, without taking into the confideration any thing for the great faving in grain,* 

 or the other operations that may be performed at the fame time, fuch as thofe of 

 winnowing or cleaning the corn, cutting ftraw into chaff, bruiting and grinding the 

 grain for cattle food or other ufes. 



Where threfhing-machines are made ufe of, it is advifed by the writer of the. 



Which is about Is. 4d. per quarter, or nearly half the price of the flail method. 



Barley. 



Gleaning and meafuring 32 quarters, at 3d. each - 



Other expenfes, as above --- 



1 15 4 



Oats. 



Gleaning and meafuring 40 quarters, at Id. each 

 Other expenfes, as before - 



1 10 8 



Or a little more than half the price of that by (he flail ; this fort of grain being commonly threfhed at 

 about Is. 3d. per quarter. 



This is without the late improvements in the machines of this kind, by which they are capable of 

 performing the work with much fewer hands, as well as of cleaning the grain and executing feveral 

 other operations, by all of which the above charges would be ftill much leffened. 



But in the Corrected Agricultural Report of Northumberland it is remarked that a threfhing-machine 

 is employed there that has been found on trial to threfli at the rate of thirty-three bufhels in the hour, 

 or two hundred and fixty-four in the day of eight hours. The ejcpenfe in the attendance of the threfhing 

 and drcffing parts of it being merely that of three women ; one to feed in, another to hand the (heaves 

 to the feeder, and a third to take away and riddle the corn after it is winnowed: confequently the threfh- 

 ingand dreffing the above number of bufhels only cofts one (hilling and fixpence, while the threfhing the 

 fame quantity by the flail would be one twenty-fifth part, or ten and a half bufhels, which at two 

 /hillings the bufliel, is twenty-one (hillings ; to which muft be added two millings for the expenfe of a 

 man and two women to affift in winnowing : which makes in all twenty-three millings. 



In the north riding of Yorkfhire, according to the Corre6ted Agricultural Survey of that diftricT:, 

 threfhing by the machine is undertaken in oats for fixpence, and wheat a (hilling the quarter, the farmer 

 finding horfes. 



* In the fame work it is likewife ftaled, that in this, fome reckon a profit of at lead five per cent.; 

 others, as equal to the feed and price of threfhing, which is fomewhat more than half the price of the. 

 flail method ; this fort of grain having of late been ufually thrcmed at about Is, 6d. the quarter.
