adjoining and furrounding vineyards do not pro- 

 duce the mufcadine grape of any thing like the 

 fame quality. Of this, too, I have my own perfo- 

 nal experience. 



In France, it would be proper to look for (heU 

 tered afpects, fuch as we have been defcribing, in 

 places where there are white ftones in abundance, 

 the colour of which is the bed adapted to reverbe- 

 rate the rays of the Sun. Nay, I believe, that 

 marl is indebted to it's white colour, for part of the 

 heat which it communicates to the lands on which 

 it is fpread ; for it reflects upon them the rays of 

 the Sun with fo much activity, as to burn up the 

 firft (hoots of many herbs. This is the reafon, if 

 I am not miftaken, why marl, which has, in other 

 refpedts, the principles of fecundation within it- 

 felf, kills a great many of the fmaller herbs, which 

 are accufromed to grow under the (hade of the 

 corn, and whofe firft leaves are more tender than 

 thofe of corn, which is, in general, the mod hardy 

 of gramineous plants. 



It would be farther neceflary to look for thofe 

 fortunate cxpofures in the vicinity of the Sea, and 

 under the influence of it's winds, which are fo ne-

 veral of them refufe to grow in the inland parts of 

 a country. Such is, among others, the olive-tree,
