Grafting—Perhaps the most interesting thing to be related is the result of attempts to determine the species of hickories best suited as stock for the fine varieties of hickories that we have. In preparation for this and through the kindness of Mr. Henry Hicks of Westbury, L. I., over 100 each of hickory trees of several species were obtained and set out in the fall of 1919. They were in fine condition for grafting this spring. There are some fifteen species of hickories native in the United States. The fine varieties of hickories that we have which are generally supposed to be largely shagbarks may prove to be much better adapted for grafting on some stocks than on others. A knowledge of this will prove to be of great value in top working. The grafting was done by Dr. Deming, on May 29, 30,31 and June 1 of this year, 31 grafts being set on shagbark stock, 52 on mockernut, 53 on pignut, 47 on pecan and 91 on bitternut, a total of 274. There were also 343 walnut grafts set on walnuts of four species. The results of this work are summarized in the tables following:
