'froft and winter rains come on, will receive a much 

 greater (hare of their influence than any other. 



If the land be left in a rough ftate, there is fel- 

 dom time for the rains and froft to affect more 

 than the outfide of the large clods or lumps : the 

 outfide will indeed be pulverized, but the middle 

 of the lumps, wherever they are large, will be 

 found nearly in the fame hard (tiff ftate as when 

 turned up by the plough. Hence it muft appear 

 to every one, that in this cafe the benefit of air, 

 winter rains, and frofts, on lands thus left, is 

 partial; and the confequence is, that harrowing 

 it in the fpring, when thefe are over, is too late 

 for its receiving the benefit which would have 

 accrued from them, and the power of vegetation 

 is not fo vigorous. 



But to make winter fallows as fine as they can be 

 in autumn, and then ridge them up in that pul- 

 verized ftate, is acting moil agreeably to nature. 

 Tue greateft poflible quantity of furface is by this 

 means expofed to the atmofphere; and the fand is 

 lefc in a ftate wherein the rains and the frofts are 

 mod eafily admiftible. They will then penetrate 

 and enrich the whole mafs to a greater depth.
