The commercial side of hickory raising, is being worked out for the pecan only at the present time. We may assume that several of the other species of hickory adapted to growing in the north, will equal pecans in importance, eventually. The reason for that is because some of the other hickories stand quite as high as the pecan in food value and general excellence. At the time of writing, low grade seedling shellbark nuts from the West are selling in the retail market in New York for forty cents a pound. I have seen better nuts of this species being loaded on the cars in Ohio at fifty cents a bushel. The present New York price, to be sure, represents a profiteering war price. Fine grades of shagbark hickories and some of the hybrids will command prices equally high with prices for best pecans in the market of to-morrow.
Voice: Will it be practical to plant nuts, get young plants, and then bud or graft them?
Dr. Morris: Yes, that is what we do. It is practical to plant nuts for the purpose of getting a stock, but not for the purpose of getting nuts. But we plant them in the nursery rows, and then when they are two years old, preferably (some like three-year-old trees), we graft them over to good kinds in the nursery row; then they remain there for a year or two, and are transferred or sold. We now have members of this association who are experts in grafting nut trees who make that a business. It is not generally known that we have in this country three journals devoted wholly to the subject of nut culture. We have nurserymen who make a specialty of grafted nut trees of the very best sorts, so that one may perhaps take up this mode of farming more profitably today than almost any other sort of farming. One gentleman in Pennsylvania told me he made thirty thousand dollars on one crop of chestnuts two years ago, cultivated chestnuts. He had thirty acres, and no tree was yet fourteen years of age. His net profit beyond all expenses was thirty thousand dollars that year. There are probably very few professional men who make more than that a year. Many men are making good, comfortable incomes out of their nut orchards. It is the best insurance against the needs of old age, the best sort of life insurance.
Voice: Do you use anything besides the hickory as stock for grafting on?
Dr. Morris: Yes, we have some experimenting to do in order to learn which stock will best serve for a certain variety. We find that one species or variety of hickory will accept other varieties of that species well, but perhaps it will not accept another species. We do know that certain kinds do remarkably well on certain stocks; but the entire range of that subject has not as yet been worked out.
Question: Does the stock you graft on have any effect on the quality of the fruit?
Dr. Morris: The stock on which you graft is supposed to have no effect at all on the quality of the fruit. But there are some exceptions. We learned that in orange grafting. A naval orange grafted on the wild orange stock might be raggy, not full of juice; while when grafted on the trifoliate orange stock might be heavy and full of juice. So in that case the stock did have some influence upon the graft; and there are other instances. But as a rule we assume that the stock has no influence upon the graft in regard to the validity of character.
Question: Are pecans a variety of hickory?
Dr. Morris: Yes, pecans are hickories. The Indians gave it the name of pekan. The French spelled it pecanne, so that has been spelled as the pecan, without the necessary other part of its name, hickory. We should always say pecan hickory—always.
Dr. Kellogg: Dr. Morris, how old hickories may be used for grafting?
