BENCH-GRAFTING RESISTANT VINES. 235 



Mondeuse on Rupestris du Lot; 910 Champin graft, 

 scions of two eyes. The unions of this kind formed 

 better than those of Zinfandel on Rnpestris du Lot ; 

 most of them were well formed and strong. The shoots 

 were well developed, and the roots more numerous than 

 those of the grafts of Zinfandel on Rupestris du Lot 

 with the same kind of treatment. The water level at the 

 time of digging was at a depth of 3 feet, so that the roots 

 could only be followed to a depth of about 4 feet, but they 

 undoubtedly went deeper. It was also observed here that the 

 roots of the Rupestris du Lot penetrated the soil verti- 

 cally through alternating layers of compact soil and layers 

 of coarse but fertile sandy soil without the slightest devia- 

 tion, and sent out an equal growth of secondary rootlets into 

 .all layers, except that most of the finer rootlets and root- 

 hairs were formed on the lower parts of the main roots, 

 3 or more feet deep ; 452 grafts made first-class unions, that 

 is a total of 54 per cent. Moreover, about 10 per cent, made 

 unions that were more or less imperfect. 



Lenoir grafted with Zinfandel ; 96 English grafts, scions 

 of two eyes. Most of the grafts had formed no roots, and 

 only three had started growth, one of which was a strong, 

 good graft, with long, thick roots. 



American Rulander grafted with Zinfandel ; 26 English 

 grafts, scions of two eyes. The grafts were all dead. 



Herbemont grafted with Zinfandel; 21 English grafts, 

 scions of two eyes. The grafts were all dead. 



Cunningham grafted with Zinfandel 27 English grafts, 

 .scions of two eyes. Two grafts showed good unions. They 

 had a well-developed root system with thick roots, which 

 grew horizontally at first and then straight down. Only 

 7 per cent, grew in all. 



Riparia Gloire de Montpellier grafted with Zinfandel 

 100 Champin grafts, scions of two eyes. The unions were 

 not of very good quality. The shoots were short and thin 

 and altogether of scanty growth. The roots were mostly 

 thin and branching, but often very long ; most of the main 

 roots did not penetrate the soil, but grew more or less hori- 

 zontally, and scarcely deeper than 1 J feet below the surface. 

 It was noticeable that the roots of the Riparia Gloire de 

 Montpellier followed the softer layers and streaks in the 

 soil and lacked the penetrating power of the Rupestris St.
