always lying open ; and Two plowed Farrows (that 

 is, one plowed under another) are as much more 

 advantageous for the nourifhing a Crop, as Two 

 Bufhels of Oats are better than one for nourifhing an 

 Horfe : Or if the Staple of the Land be too thin or 

 (hallow, wc can help it by raifing the Ridges prepared 

 for the Rows the higher above the Level. 



9. We alfo raife an high Ridge in the Middle of 

 each Interval above the Wheat before Winter, to pro- 

 tect it from the cold Winds, and to prevent the Snow 

 from being driven away by them. And the Furrows 

 or Trenches, from whence the Earth of thefe Ridges 

 is taken, ferve to drain off the Water from the 

 Wheat, fo that, being drier, it mull be warmer 

 than the harrowed Wheat, which has neither Furrows 

 to keep it dry, nor Fridges to ilielter it (a) 9 as every 

 Row of ours has on both Sides of it. 

 I V. The Condition in ivbicb the Land is left after a Crop. 



The different Condition the Land is left in after a 

 Crop (b) y by the one and the other Hufbandry, is 



not 



(a) This is a Miftake ; for the Ridges in the Middle of the 

 Intervals do not always, nor often in tnin fhallow Land lie high 

 enough to make a Shelter to the Rows, they being higher: But 

 when Wheat is drilled on the Level, 'tis fheitered by the Ridgea 

 raifed in the Intervals : But we never weed or hand- hoe Wheat 

 before the Spring. 



(b) if indifferent Land be well pulverized by the Plough for 

 one whole Year, it will produce a good Crop : But then, if, in- 

 itead of being fown, it be kept pulverized on for another Year 

 without being exhaufied by any Vegetables, it will acquire from 

 the Atmofphere an extraordinary great Degree of Fertility more 

 than it had before fuch Second Year's Puiveration and CJnex- 

 Lauftion. This being granted, which no Man of Experience can 

 deny, what Reafon can there be why fuch a Number of Plants, 

 competent for a profitable Crop, may not be maintained on it the 

 Second Year, that may keep the Degree of their Exhauftion in 

 ^Equilibria with that Degree of Fertility, which the fame Land 

 had acquired at the End of the Firft Year of its Puiveration, the 

 fame Degree of Puiveration being continued to it by Hoeing in 

 the Second Year ? Cr why may it not produce annual Crops al- 

 ways, if the fame Equilibrium be continually kept ? Two unan-
