*One scion ■was overlooked in tying and •waxing, other^wise apparently ^we 

 ■would have had 100% catches. 



In the abo^e t^wo groups of liickorics the one ■where scioiLs ■were cut 

 from young, rapidly growing trees, contrasts unraistakaTbly with those 

 where scions were cut from old bearing trees. The same is shown in 

 tlie table of black walnut grafts, where the Alley, Adams, and O'Con- 

 nor scions were cut from old bearing trees, and the others from young, 

 rapidly growing trees. 



The poor success with the heartnuts is quiie in line with previous 

 attempts at propagating this species by grafting. Results shown here 

 with the butternut are deemed reasonably satisfactory, in view of the 

 well known difficulty of grafting this species. It should be noted here 

 that, in the case of every graft that took and grew, it was the small 

 buds that were successful, not the large ones. The total lack of suc- 

 cess with the Persian walnut is inexplicable to the writer, but he knows 

 of no previous attempts to graft Persian Avalnut on Persian walnut root. 



Black walnuts sjiow a very high percentage of catches, in the case 

 of the Thomas and Ten Eyck varieties 100%, but in the case of the 

 Stabler this is reduced to 51.2%. I would say in this connection that
