flourisli in dry locations here, and as it suckers profusely 

 and does not take the graft as readily as the two former 

 classes, it is not largely propagated. 



ViTis Labrusca. — This can hardly be called entirely 

 resistant, as the insect feeds on its roots to some extent> 

 though not to the extent that it does on the vinifera. 

 In the Simonton vineyard were some Catawbas and Isa- 

 bellas mixed in a block of old Mission vines, which re- 

 mained, to all appearances, healthy and produced fair 

 crops after the Mission had entirely succumbed to the 

 phylloxera. I would not, however, recommend it as a 

 resistant stock, as the whole class roots shallow, and is, 

 therefore, apt to suffer from drouth. 



ViTis Californica. — This, our native wild grape, 

 found all along our creeks and ravines, was at one 

 time considered entirely resistant, although it was 

 suspected that its soft, spongy roots would be as sub- 

 ject to the attacks of the insect as those of the viniferay 

 which they strongly resemble. This surmise proved 

 correct, and it is not considered a resistant to-day, 

 though its vigor and strong growth will doubtless en- 

 able it to resist longer than the vinifera, the attacks 

 of the phylloxera. Neither will it flourish in dry, shal- 

 low soils. It takes the graft readily, perhaps more so 

 than any other class, but does not make so good a junc- 

 tion as riparia. 



ViTis Arizonica. — This seems to be an intermediate 

 between riparia and Calif ornica, of upright growth and 

 shining leaves. It never seemed to flourish well and 

 has not been fully tried. 



The Solonis, Vialla, Berlandieri or Monticola, Doani- 

 ana, Champini and Lavata have their admirers in France, 

 and Professor Munson thinks highly of them as resist- 

 ants, but they have not been fully tried in this State. 

 I believe, from experience up to date, that the riparia 

 will be safest to plant and graft. Cuttings of the riparia
