most generally and tenaciously resistant toward the attacks of 

 the phylloxera. It is very little liable to mildew. 



2. Vitis Cordifolia, the southern riverside grape, so greatly 

 resembles the Riparia that for some time it was not distin- 

 guished as a separate species. While it is undoubtedly a very 

 resistant stock, the fact that it is at home in a region noted 

 for its perpetually moist atmosphere, seems to render it less 

 promising for general success in California than the Riparia^ 

 over which, so far as known, it possesses no special advan- 

 tages, save, perhaps in the case of very heavy adobe soils, to 

 which it is better adapted than the Riparia. 



3. The Vitis crstivalis or summer grape is a native of the 

 uplands of the States east of the Mississippi, and is at home 

 on loam soils of good or fair fertility. It also descends into 

 the lowlands of the smaller streams, so that it and the Riparia 

 vine are not uncommonly seen side by side. But it is rarely 

 if ever found in the larger bottoms, though quite at home in 

 .the lighter and usually well drained "second bottoms " or 

 f ' hammocks." Unlike the riverside grape, it objects to " wet 

 feet." It is a little subject to mildew. Of the cultivated 

 varieties of the &stivalis grape, those of 'chief interest as 

 resistants are Norton's Virginia, Herbemont, and the well- 

 known Lenoir. The cuttings of these, as well as the wild 

 vine, root with some difficulty; they should be rooted in 

 nursery, and not in the vineyard itself. 



A very striking example of the resistant powers of the wild 

 sEstiralis vine exists in this State, in the vineyard of John R. 

 Wolfskill, on Ptitah Creek, two miles from Winters, just within 

 .Solano County. This case was alluded to in a previous re- 

 port (1882), but the stock was incorrectly stated to be Lenoir. 

 It has since been ascertained by Mr. W. G. Klee to be a wild 

 ^stivalis variety obtained at least ten years ago by Mr. 

 Wolfskill from Alabama, under the name of "coon grape." 

 It has a leaf much like the Lenoir, but bears a small, com-
