AND WIKE MAKING. 7 



abandoned in the Eastern States. In the structure of 

 the roots, a greater affinity exists between Vinifera and 

 Californica than between Vinifera and Bourquiniana, as 

 those of the two first named are soft and spongy, while 

 those of the Bourquiniana are hard and firm ; so much so 

 that Mr. Munson himself classes them as resistant. He 

 claims that he has traced Bourquiniana back to Southern 

 France. If this is correct, it seems very strange that 

 France especially should so largely order, as they did in 

 1874-7, from Texas and Missouri, the cuttings of Bour- 

 quiniana, because they found them resistant. 



I have thought it my duty to give the subject of 

 classification a great deal more room than it would 

 otherwise occupy, and to state my objections to a system 

 which, with the exceptions named, I consider the most 

 perfect and complete yet introduced. Professor Mun- 

 son deserves the thanks of all grape growers for his sys- 

 tematic efforts and for the large number of valuable 

 seedlings he has produced by crossing and hybridizing. 

 He may well feel an honorable pride in his achievements. 

 With these few introductory remarks, we will let his 

 classification and synopsis speak for themselves.
