 to pay well for the trouble. 



Every machine mud be worked by fome 

 power -, and whether the power is applied by 

 by means of living animals, by fire, wind, or 

 water, the effect will be the fame. The ufe of 

 water is attended with the lead expence j but 

 it is confined to oarti "ular fuuations. Wind 

 is Uncertain, e< . co a proverb. Fire, in coun- 

 tries where coal is cheap, may be applied to 

 great advantage ; fleam-engines being now 

 improved to a degree of perfection that hereto- 

 fore they were thought impoflibie of attain ing„ 

 They are dangerous, however, where flraw is 

 concerned. But the power moft generally 

 ufed to put the thrafhing-machine in motion, 

 is that of living animals. A farmer intending 

 to erect one of thefe machines, will no doubt 

 proportion if to the fize of his farm, and to the 

 quantity of corn he means to thrafh ; though, 

 indeed, the power may be applied to many 

 other ufes. The dimenfions of this machine 

 may be fuch as to work with one horfe only ; 

 or it may be large enough to work with half a 

 dozen, where the farm is very extenfjve, and 

 expedition is neceMary.
