THE PRACTICE QF THE 



To underftand his eftimate, it may be pro- 

 per to obferve, that the Irilh plantation-acre is 

 to the Englifh flatute acre, as 7840 fquare 

 yards to 4840 ; or nearly as 8 to 5. The Irilh

Their barrel of wheat is 20 ftone, or 280

Mr. Baker being experimenter to the Dublin 

 fociety, he was directed by them to make a 

 comparative experiment of the drill and broad- 

 caft methods : and he allotted one plantation 

 acre to be drilled annually with wheat, and 

 horfe-hoed for a courfe of years ; and he fowed 

 two contiguous half-acres, of the fame foil as 

 the other, broad-caft ; the feed of one half- 

 acre to be covered with the plough, and of the 

 other with the harrow. 



Thefe two acres were drilled with turnips 

 in 1764 upon five-feet ridges, which were 

 horfe-hoed. And in 1765 they were fown 

 with barley, which was drilled, two rows 

 upon each ridge ; the beft part produced a good 

 crop, the reft was inferior ; the barley being 

 fown too late, and the feafon unfavourable.
