stock without extending to the scion. Sjieculation would introduce the 

 idea that lignification relates to a liormone influence proceeding from 

 the leaves of a tree and that the leafless scion does not send forth 

 liormones for stimulating the cells of the scion to the point of furnish- 

 ing enzymes for wood building. 



Perhaps the most interesting part of new tree work relates to 

 experiments which are failures. Negative testimony is like the minor 

 key in music. There are man}- men who care to do only things that 

 "cannot be done." These are the ones who have made our progress in 

 ahnost evcrv field of human activitv. 



STOCKS FOR HICKORIES 

 Willard G. B'hvhy, Long Island 



Mr. Bixbv: The sheets whicli I am distributing to you contain 

 tables to which I shall refer during this talk. But first I will give a 

 little foreword regarding the trees. The trees enumerated in the 

 tables shown were nearly all given me by Mr. Henry Hicks of Isaac 

 Hicks & Son, Westbury, Long Island, and were taken to Baldwin and 

 set out in the fall, practically the entire roots being saved and later 

 the trees severely cut back. They were transplanted without loss 

 except in the case of the shagbark, and those lost were all under-sized 

 trees. All of the hickories were of one age, but those lost were ones 

 Avhich had not made normal growth and had they been discarded in the 

 beginning there would have been no loss whatever in the transplanting 

 of 300 or 400 trees. Later, in the spring of 192i, I found some 

 loose bark pignut (Carya ovalis) seedlings on a farm not far away 

 from my place, and these were also transplanted ; but they were too 

 small to graft this year. These experiments in grafting, made during 

 1923 and 1924, have shown us some new things. With some of the 

 walnuts we had 100 per cent success. With the hickories there was 

 not 100 per cent success, but that was due to the fact that we were put- 

 ting scions on stocks that were not congenial in many instajices. You 

 will notice the results as shown on the tables.
