relationship with Vinifera. As we shall see when studying 

 grafting, this concordance of affinity accounts for the produc- 

 tion of grafts upon Jacquez or Herbemont being normal and 

 equal to that of the French cepages when ungrafted ; it 

 accounts also for the maturation of their fruit not being 

 hastened, as takes place in the case of grafts upon Riparia

and Rupestris, which are also more fructiferous. This is 

 caused by the difference of affinity existing between these 

 graft-bearers and European vines. 



These cepages do not root as freely from cuttings or 

 grafted-cuttings as French vines, or Riparia, Vialla, etc., but 

 the proportion of strike is, however, high, and often attains, 

 with ordinary barked cuttings, 80 to 85 per cent. When the 

 nurseries are established carefully, when the grafts are well
