the earth has veins jproducing different juices, 
more or lefs nutritious. Hitherto I had been 
induced to believe, that a fandy foil, of what- 
ever kind, that of the Nimiquas for example, 
muft produce falts injurious to the plants 
growing on it, and confequently prejudicial to 
cattle ; and that, on the contrary, the delight- 
ful countries of Auteniqua and CafTraria, the 
foil of which is good and well watered, muft 
furnifli in abundance the juices beneficial to 
life : but I abide by the fad, more certain 
than any conjectures, and leave the talk of 
inveftlgating its caufes to any one who may 
choofe to undertake it. I fliall only remark, that 
I have generally obferved land too much water-
