Champin grafts with scions of two eyes and one eye, as 

 in the last two experiments, but planted out immediately 

 after grafting without previous callusing in sand; 360 

 Zinfandel on Rupestris du Lot. The unions of the grafts 

 in this experiment were of medium quality, and an especi- 

 ally high amount of second-class grafts were noticed in the 

 lot of 180 grafts with two eyes. The grafts with scions of 

 one eye did, in this experiment, comparatively better than 

 in other parallel experiments, as there was less difference in 

 the percentage of unions ; 28 per cent, of the grafts with 

 two eyes left on the scions had made good unions, and 24 

 per cent, of the grafts with one eye, while in the first case 

 there were found 17 per cent, of grafts with imperfect unions, 

 ajid in the other only 9 per cent. 



Champin grafts with scions of two eyes and one eye, as in 

 last two experiments, but callused in straw; 360 Zinfandel 

 on Rupestris du Lot. The unions of the grafts in this 

 experiment were in every respect inferior to those of the 

 grafts callused in sand, though the shoots were well 

 developed (average length 2 feet), and the roots proportion- 

 ately. There was very little difference in the general 

 appearance of the grafts with two-eye scions and of those 

 with the one-eye scions. The percentage of grown and well- 

 developed grafts of the two kinds are also close together 

 88 grafts grew of the first kind with two eyes, that is at the 

 rate of 49 per cent. ; and 76 grew of the second kind, that 

 is 43 per cent. The second-class grafts with imperfect unions 

 grew at the rate of 17 per cent, and 8 per cent, respectively. 



America grafted with Zinfandel ; ten-year-old roots, scions 

 of two eyes, English graft. Only three grafts had started, 

 and showed imperfect unions and poorly developed shoots. 



Munson grafted with Zinfandel ; thirteen one-year-old 

 roots, scions of two eyes, English graft ; nine of the thirteen 

 grafts grew, that is 69 per cent. The unions were mostly 

 good and strong. The grafts showed a strong root system, 

 but the shoots did not show a proportionate growth. 



Champini grafted with Zinfandel ; ten one-year-old roots, 

 scions of two eyes, English graft. Only a few showed 

 growth, and the unions were very imperfect. 



Elvicand grafted with Zinfandel ; seven one-year-old roots, 

 scions of two eyes, English graft. None had made a good 

 union.
