196 AMERICAN VINES. 



Among cepages of this group we will mention the Canada 

 Riparia Nos. 2401 and 2412, which are graft-bearers advo- 

 cated by Couderc. 



Of the hybrids of this group, obtained in France, which we 

 have studied, some have l /^ Vinifera strain (Canada X 

 Riparia), some J/, others ^. 



One of these, Oporto X Colombeau, No. 1401 of Couderc, 

 has been recommended as a direct-producer. It gives, it is 

 true, fruit of a fairly large size, but foxy taste. Its resist- 

 ance to phylloxera is slightly superior to that of York; but 

 its area of adaptation is very limited. It can only be culti- 

 vated in siliceous or slightly calcareous soils, where grafted 

 American vines grow very well.
