foliage like that of an apricot, and is very resistant to 

 Phylloxera. One of the best varieties is Rkpestfis du 

 Lot, its index of resistance against the Phylloxera being 

 given at --, and seems also to do fairly well in 

 calcareous soils. This vine has been introduced in our 

 Islands in 1919, along with other American and Hybrid- 

 American vines 



There are other thirteen species of American vines 

 viz : Vilis candicans Engelm , K cinerra Engelm., V. 

 mowticola Buckley, K calif ornica Bentham.,. V. caribaea 

 D. C., V. coriacea Sputtleworth., V. cordifolia Michaux., 

 K arizonica Engelm., K rnbra Michaux., V. bicol r 

 Leconte., V. Lincecomii Buckley., K aestivahs Michaux. 

 and V. riparia. Michaux. ; but with the exception of 

 the last two the others have little interest for the vine 

 grower. V. aestivalis, which is nearly allied to K bicolor 

 and to F. Lincecomii, is the summer grape of the central 

 and eastern states, and has given origin to many varieties 

 which are largely cultivated in the United States both 

 as table grapes and for the production of wine. The 

 principal varieties are Jacques, Herbemont, Cunningham, 

 Black July and Elsinburg. Jacques is also extensively 

 cultivated in Italy and Sicily, sometimes as stock for 

 European vines, but chiefly as a direct producer. It 

 is stated to be a hybrid with the European vine, and its 

 grape is small, rather deficient in juice, but intensely 

 coloured, and is fairly resistant to Phylloxera, ahhough 

 very liable to vine-blight. The resistance of K aestivalis 

 is given at .--, and that of its hybrids or varieties at 

 about \\. 



On the other hand Vitis riparia, the river-grape, 

 native of Ohio and other alluvial regions along the 

 Misissippi and Missouri, and most of its varieties, re- 

 quire a rich alluvial soil, and are very susceptible to the 

 presence of lime, hence prima facie they cannot thrive 

 well in our soils, although they have a very vigorous
