BENCH-GRAFTING EESISTANT VINES. 217 



heat (probably on the steamer) and had suffered a fermenta- 

 tion which had completely blackened the pith and inner 

 bark. These were planted out in the nursery without graft- 

 ing, but failed to grow. The remainder were a little better, 

 but were full of dark streaks, showing that they also had 

 suffered from the heat but in a less degree. These were 

 grafted, and the ill-success of the grafts was undoubtedly 

 due to this bad condition of the stocks. This showed the 

 danger of importing large quantities of cuttings from so 

 distant a place, and it was determined for the next year's 

 experiments to use only cuttings grown in California. 



Adaptability of various Varieties of Vinifera to various 

 Resistant Stocks. One of the principal experiments made 

 was to test the adaptability of certain Vinifera varieties for 

 different stocks, that is to say, to test on which resistant 

 stocks certain varieties did best. The negative results (the 

 cases in which there was very poor or no growth) of course 

 taught nothing, as it was impossible to tell whether the 

 failure was due to lack of affinity of the scion for the stock, 

 or simply to the bad condition of the stock. The positive 

 results, where there was good growth and good unions, are 

 however worth chronicling. 



The varieties which grew well and made good unions on 

 Riparia Gloire de Montpellier were : 



Aramon Marsanne 



Blue Portuguese Peruno 



Chardonay Petit Bouschet 



Folle Blanche Seedless Sultana 



Gros Mansenc Semillon 



Kleinberger Valdepenas.
