ancient and prmioj^enial Covenns; or this Globe, is carried ofFM-^ »ever 

 by Plants and Vegetables, appears from comparing the prefent 

 State of the Plains o^ Africa, with what they were, in former 

 Ages. For thefe are never manured ; yet the fame Fertility 

 in the Soil , and the like Plenty and Abundance, that have 

 been recorded of their Crops, for above thefe two thoufand 

 Years, continue to this Day. Now if the Nature of Vegetables 

 was fuch, as to make the Ground they grow upon, both hol- 

 lo wer and lower, by gradually wafting and confuming it\ Africa, 

 by this Time, would have been drained of it's whole Stock ; 

 and nothing could have remained, at prefent, of this rich and 

 fruitful Country, but a barren Suhftratum of Clay or Gravel. 



■ Arguments

principal Arguments, which I have advanced, for that an-fam?with*^ 

 nual Increale which is fuppofed, {Tra'u. p. 441.) to have been™"^" 

 made to the Land oi Egypt, was taken from Herodot^/s', who 

 tells us', that i^i the Time of My r is, eight Cuhits at leaft (ri 

 eAx;^7Dv) Were required to water the Country \ hut, in his Time, 

 fcarce nine hundred Tears afterwards, [fixteen or'] fifteen at 

 leaft (TO!:Act;i^cov) were neceffary. The Land therefore, as I con- 

 jedlure, muft have received feven Grecian Cubits oflncreafe, 

 in that Space of Time. The whole Scope of Herodotus''^ Rea- 

 foning, both in this and in other Places of the Euterpe, is to 

 this Purpofe ; not only to fliew the aftual and the general In- 

 creafe, but even, in fome Meafure, the very Proportion and 

 Quantity of what is gained every Year. And of this the Mat- 

 ters of Fa6l, related in the foregoing Paragraph, are, as he 

 calls it, m<=<- -r^^yJ-'eAoi •a^i TTis ;^'p>i5 ; a frong Proof or Evidence 

 with Regard to this Country. For if he had not preferved,
