 ploughed one field in the dry weather, and reduced it with the 

 clod-crusher to fine dust. No field has a better appearance, and 

 quite before the regular turnip-land in the country."

N.B. — When there is a coulter, which should take about 4 inches of earth, no earth 

 falls back into the furrow, which is the case if no coulter is used. Boutillier's price 

 for a great plough with coulter, chain, and wheels, with gallows complete is 6/. ;

After the land has been trench-ploughed, as described, a light 

 harrow is passed over it ; a cross-harrowing is given when ne-

 potatoe-setting plough is then used. This plough was invented 

 in 1834 or 1835, at the suggestion of the writer, by Le Boutillier, 

 the smith who devised the paddle or potatoe-digging plough. It 

 weighs about 60 lbs., and in light soils may be drawn by one 

 horse, though more work is performed by using two.

 depth, from 3 to 6 inches, regulated by the wheel, and the earth 

 is carried off 18 or 20 inches to the right by the wing of the turn-
