Before leaving the hickories, I do want to mention that I feel there is a good chance for growing pecans in this climate. I have seedling trees, now more than 20 years old, which are in bearing but do not mature their fruit. It is possible that some of these may become acclimated to an extent that their cycle of dormancy will reduce itself, bringing their period of flowering early enough in the spring to allow sufficient time and heat units for maturing the nuts. Early in my experimental work, I tested chestnuts and chinkapins but met with poor results. Only in the last few years have experiments with them been successful enough to warrant their being mentioned as commercial possibilities in the north. At present, I have several Chinese and two American varieties, as well as one chinkapin, which have proved hardy and fruitful. Further testing is necessary before I can report anything definite about them. I have grafted on native plum stock most of the almonds which have been considered hardy, including the hard-shelled varieties from Michigan and the Northland from the Pacific Coast. Some have flowered but none have set nuts. All proved too tender for our climate. I feel more hopeful for success with some of the many seedling hybrid plums I am growing. A number of these have edible kernels and the trees could be considered for their fruit as well as for the kernels of their seeds. Among other species of walnut I have tested is the heartnut, which is a sport of the Japanese walnut. This is a worthy nut and has done well when grafted on black walnut stock. Only two varieties have proved hardy and only one of these, Gellatly, has produced good crops for a long time. Were it not for the insect pests which attack it and, worse still, the sapsucker, this tree might be considered for semi-commercial use in the north. The sapsucker is a woodpecker. It chips out bark right down to the wood, girdling large limbs and killing whole sections of a tree. This results in an excessive amount of succulent, tender growth which is subsequently winter-killed. Insects attack the new shoots, laying their eggs in the bud and stem portions, causing immature growth which stunts the tree and prevents its bearing. I have also found the heartnut difficult to graft, even on black walnut, which is a favorable combination.
