104 CULTIVATION OP THE 



is indicated by the appearance of the bark, and 

 strength, and number of -the offsets, which are 

 generally more vigorous on the southern side. 



If, in considering the aptitude of the different 

 sections of our country, to the cultivation of the 

 foreign vine, any tenable analogy could be de- 

 duced, I should believe, that of the vines to be 

 introduced among us from abroad, those of the 

 Rhine and of France, north of Lyons, should be 

 cultivated in Pennsylvania and the States north 

 of the Hudson. The vines of southern France, 

 Spain, and Italy, in the Carolinas and the States 

 south of them. 



Such is the summer temperature of Pennsyl- 

 vania, that there is strong reason to believe we 

 should also succeed with those less hardy vines 

 of the south of Europe, Madeira and the islands 

 of the Levant. The vines of Switzerland strongly 

 induce a cultivation in our northern States, where, 

 from the length and heats of summer, there niay 

 be anticipated great improvement in the produc- 

 tions and vintage, as the vine is hardy and rug- 

 ged, enduring from habit the vicissitudes of a 

 capricious climate, and deriving but little benefit 

 from a cheering summer's sun. 



It is true, that the occasional mid day heats of 

 the country are of sufficient temperature whilst 

 they last, for the habits of the vine, but these are 

 generally of short duration, and continue during 

 a brief period, whilst in their warmest weather 

 the nights are uniformly cold, chilling the at- 

 mosphere with an inhospitable influence, which 

 neutralizes the advantages, which the vine would 

 otherwise receive from a cheering warmth.
