OF THE COUNTY OF DOWN. 53 



my late journey through fome of the moft improved 

 parts of Scotland ; and it has one improvement on all 

 thofe, that have come under my infpeclion, which is 

 what I call equalizing levers for adjufting the draught 

 of the horfes, which effectually prevents one horfc 

 from drawing lefs than another." Mr. Chrifty has 

 adapted to this machine one for rolling and fcotching 

 flax ; likewife a fleel mill for flour ; and he has alfo 

 added millftones for grinding oats, &c. After this it 

 is unnecefTary to add, that Mr. Chrifty has a head ad- 

 mirably fitted for inventing or improving machinery. 

 Mr. Ward, of Bangor, has a threfhing machine like- 

 wife, erected by the maker of Mr. Chrifty's ; the 

 houfe which contains it being fo lofty, that the horfes 

 work underneath in turning the large wheel, fimplifies 

 it very much. The attendance required in threfliing 

 days is, two or three horfes and a driver ; a man to 

 throw up the {heaves, one to unbind them and make 

 them ready for the peribn, who feeds the machine ; 

 and another to take away the ftraw. The man, who 

 throws up the {heaves, can likewife take away the 

 grain from the fan ; but to fill that up, and meafure it, 

 requires the interference of another. The whole num- 

 ber to carry on the bufinefs effectually, five men and a 

 boy to drive ; with this force three times the quantity 

 of grain is got out, befides its being half cleaned ; but 

 the greateft advantage attending it is the facility, with 

 which a great quantity of grain is got ready for mar- 

 ket,
