258 On the three Furroxv P long Ju 



Potatoes may be planted in the furrow after this im- 

 plement, the land having been previously ploughed and 

 manured. The distance between the rows (27 inches) 

 is however too small for the deep horse hoeings, which 

 potatoes require : but for turnips, this plough succeeds 

 admirably, and in lieu of the turnip drillhig machine. I 

 had the last season, an excellent crop of turnips, on six 

 acres of wheat stubble, by the following method. 



Immediately after the gi'ain was cut, the soil was 

 turned up by the single plough, to the depth of six 

 inches : the manure was then laid in heaps on the land, 

 and a glass phial prepared for the turnip seed, by hav- 

 ing a small quill inserted into its perforated cork. 



The first cloudy day, the manure was spread equally 

 over the ground ; the triple plough, set to the depth of 

 tliree inches, covered the manure, and in the furrow, (or 

 rather half way between the bottom of the furrow and 

 the surface) the seed was dropped from the phial. A 

 lieht roller was then drawn over the whole, in the direc- 

 tion of the plough. 



The rows of turnips are thus 27 inches asunder, in 

 wliich space a small plough, drawn by one horse, can 

 readily pass to destroy the weeds, and to earth up the 

 plants ; the hand hoe is used to cut up the weeds, and 

 superfluous turnips in the rows. 



I have no doubt, but that on a light sandy soil, this 

 kind of plough might be used for every purpose, even 

 for turning over a sod. It is calculated, that in plough- 

 ing an acre, with a furrow of nine inches, the plough- 

 man travels 11 miles; v/ith this implement he ploughs 

 three acres in travelling the same distance, and with 

 more ease, for the \^'heels will keep this plough in the
