then a plough with a double mould board 

 may be ufed, to clear the interval of the loofe 

 mould. This is bed done fometime after the 

 lafl hoeing with the hoe- plough ; for if any 

 weeds fhould in the mean time ipring up there, 

 the earth raifed by the double board plough 

 will be thrown to the right and' left up ta 

 the ridges, and will cover and fmother thefe 

 young weeds, will quite clear, widen, and 

 deepen the furrows in the intervals, and by 

 that means the new ridges will be deeper in 

 fine loofe mould. The double mould board 

 plough is very convenient to be ufed for this 

 lafl operation, but mould not be made ufe of 

 inftead of the hoe-plough, as fome do for the 

 greater difpatch ; but this is an argument 

 againft the ufe of it at other times, for it is 

 eiTential to expofe the earth for fome time to 

 the influences of the atmofphere, which is not 

 done fo fully when it is turned up at once to 

 both ridges by the double board plough, as it 

 is when turned up in two furrows feparately, 

 and at different times by the hoe-plough, by 

 ufmg which conftantly the furface is more en- 

 larged and expoied, and the land more im- 

 proved, than by uiing any other iniirument, 

 cultivators, or any others, that have been hi- 

 therto fubftituted in the room of the hoe- 

 plough.

 man, to make the new ridges ftraight, and if
