It is interesting to note that in his extensive hickory experiments Dr. Dunstan is using pecan stocks. He uses the bark-slot method of grafting and hot wax compounded of 10 parts resin, 2 parts beeswax and one part Kieselguhr. Both method and wax he finds highly successful. Dr. Dunstan also reports a Mahan pecan grafted on a white or mockernut hickory stock that produces heavy crops of well-filled nuts. This is an exceptional performance for this variety. Mr. Fayette Etter, of Pennsylvania, supports Dr. Dunstan in the use of pecan stocks for hickories. He states that the young trees grow more rapidly in the nursery, transplant better, and grow faster thereafter than when on hickory stocks. Mr. A. G. Hirschi, of Oklahoma reports that in the hilly "blackjack" country of southeastern Oklahoma the scrub has been cleared away and a 40-acre project of grafting the native hickory (probably white or mockernut) with pecan has been established. The land has been terraced and is cropped with cotton. The results have been so satisfactory that this plot in one year carried off more prizes on pecans than any other entry within the state. Mr. Harald E. Hammar reports from Louisiana that there has been some grafting of pecan on hickory, species not specified. The older trees show a decided overgrowth of the hickory stock by the more vigorous pecan, in some cases the diameter being almost double above the graft of that below. In virtually all cases of topworking hickory on pecan, or vice versa, the bark slot graft has been used. In point of preference of named varieties, Michigan suggests Abscoda, Ohio suggests Stafford, while Pennsylvania recommends Glover, Goheen, Whitney and Weschcke, in that order. In naming the insects and diseases that attack the hickories, Pennsylvania offers the following rather appalling list: Nut curculio Hickory shuckworm Galls Spider mites Twig girdlers Fall web worm Pecan phylloxera Black pecan aphids Flathead apple borer Other unnamed borers Those that know Mr. Etter will understand that this formidable list is due to his excellent powers of observation and his integrity rather than to the likelihood that the state of Pennsylvania is worse plagued with insects than others. Dr. Dunstan lists leaf-spot along with some of those listed above, but adds that none are generally serious. This is corroborated by other reporters. Wild nuts are generally harvested for home use. Commercial marketing, reported by Pennsylvania, Indiana, West Virginia, Virginia and North Carolina, is in all cases local. Usually the nuts are marketed whole, but occasionally home-picked kernels are sold. Good stands of second-growth shagbark hickory are reported in Pennsylvania. Kansas reports limited shellbark and bitternut stands. West Virginia reports considerable stands of young shagbark and pignut, while North Carolina reports small stands of mockernut.
