Condition when scion and suckers were cut. The follow- 

 ing observations were made during 14th to 18th July, when 

 the roots of the scions and the suckers were cut : 



English grafts with scions of two eyes ; 180 Zinfandel on 

 Kupestris du Lot. Almost all the grafts had started to 

 grow; about 50 per cent, of the grafts showed roots on the 

 scions ; 162 grafts had started, that is 90 per cent. 



English grafts with scions of one eye; 180 Zinfandel on 

 Rupestris du Lot. A lower percentage than of the above 

 had developed shoots (78 per cent.), but the roots on the 

 scions were less developed and fewer in number. 



Champin grafts with scions of two eyes ; 180 Zinfandel 

 on Rupestris du Lot. The scions had well developed 

 shoots, but also a good many strong roots on the bases of the 

 scions. Of the 180 grafts, 165 were growing, that is about 

 92 per cent. 



Champin grafts with scions of one eye ; 180 Zinfandel on 

 Rupestris du Lot. This lot was better developed than 

 that with two eyes left on the scions ; less strong roots were 

 found on the scions, but only 150 were growing, that is about 

 83 per cent. 



Champin grafts with scions of one eye ; 1 80 Zinfandel on 

 Rupestris du Lot ; planted out immediately after grafting. 

 The unions of the grafts that were growing seemed to have 

 joined very well ; the soil near to the scions was dry, so that 

 but few roots had developed, the 75 grafts growing made but 

 a low percentage of the whole, about 42 per cent. 



Champin grafts with scions of two eyes ; 180 Zinfandel 

 on Rupestris du Lot ; planted out immediately after 

 grafting. The grafts were in about the same condition, but 

 showed a higher percentage of growing grafts ; of the 180 

 grafts, 98 were growing, that is about 54 per cent. 



Champin grafts with scions of one eye ; 180 Ziufandel on 

 Rupestris du Lot ; grafts callused in the straw. The 

 scions showed small and few roots, and the number of 

 growing grafts was 154, that is about 85 per cent. 



Champin grafts with scions of two eyes ; 180 Zinfandel 

 on Rupestris du Lot; grafts callused in the straw. The 

 grafts of this and the foregoing experiment (callusing in 

 straw) looked the best of all the grafts made, and had very 

 well developed shoots, with an average length of 10 inches ; 

 the proportion of growing grafts was 90 per cent.
