In a paper which Dr. Morris is to deliver he will tell us about top working hickory trees. This is a matter of great interest for top working existing trees is the method which at the present time promises to be the means of getting our first orchards of fine hickories in bearing condition.
The earliest instance of which we know anything of grafted hickories is that of the Elliot hickory owned by the late Whitney Eliot, of North Haven, Conn. This was awarded a prize offered by the late A. J. Coe of. Meriden Conn., for the best hickory nut exhibited at the December meeting of the Connecticut Agricultural Society in 1892. According to the Bulletin of the U. S. Dept. of Agriculture on "Nut Culture in the U. S.," 1896, this was the product of a grafted tree. I have never seen a specimen of the nut although I understand that the tree is still standing. I have been unable to get any definite information as to when the grafting was done, methods used, etc.
The next instance of successful hickory grafting and the one which is best known is the work of the late Henry Hales of Ridgewood, N. J. When he purchased his place some fifty years ago, he found on it a fine shagbark hickory tree. This had been standing longer than the oldest inhabitant could remember and it is supposed to have been one of the original forest trees of that section and spared on account of the excellent nuts it bore. It came to the attention of the late Andrew S. Fuller, author of the "Nut Culturist" published in 1896, and was described by him in 1870 in the Rural New Yorker. Shortly after this description, Mr. Hales received many requests for scions to which he generously responded and any propagator who thought he could propagate this hickory was given a chance to try, the conditions being that one-half of the successfully grafted trees should belong to Mr. Hales in payment for the scions sent. During the next ten years orders for scions were so numerous that the old tree was kept pretty well pruned. Mr. Hales received during the period only about two dozen trees from the thousands of scions which he sent out. According to Fuller's "Nut Culturist" these were largely grafted by Mr. J. R. Trumpey of Flushing, N. Y., now a part of New York City. Information which I received at the Hales place was that the trees growing there were grafted by Jackson Dawson of the Arnold Arboretum about 1891. Inasmuch as there appear to be trees of two different ages there it is probable that some trees were from one propagator and some from the other. The trees grafted by Jackson Dawson we know were on bitternut root and it seems likely that the others were also for one tree is not like the others and I was informed that that was a grafted tree, but the graft died and a shoot came out at the base of the graft which was thought to be from the graft but, after the tree had grown it became evident that it was not. The buds of this tree show evidence of the bitternut. The nuts, however are not pure bitternut and the tree is seemingly a bitternut x shagbark hybrid. All of the trees grafted by Jackson Dawson were bench grafted in the greenhouse on especially grown stocks. I have two trees on my place from Thomas Meehan & Sons, Germantown, Pa., propagated in the same way and, when received, the long tap roots were coiled up like springs showing that the trees had been grown in pots. These trees, however, have grown well since I planted them out though they were very small and feeble when set out. These grafted Hales trees at the Hales place bore nuts in eighteen to twenty years after grafting. They bore for about five years and then ceased bearing. I went to see them for the reason that I was informed by Miss Hales that the trees were not looking satisfactorily and she was afraid there was some disease on them. I requested the U. S. Dept. of Agriculture to allow Mr. S. M. McMurran, who has made a study of pecan rosette, to come and look at the trees for it seemed to me that they were similarly affected. He took specimens of the leaves and reported that he could find no evidence of insect or fungus trouble. He also made a careful examination of the soil, and the farm was gone over carefully looking at the pecan and hickory trees growing there of which there are a large number. Most of these did not seem to be in good condition although a few did. Tests made of the soil seemed to show that it was not the kind of soil in which hickories and pecans do their best. It was also ascertained that while Mr. Hales senior was living the trees had received an application of manure every year. Since his death they have not. This, in connection with the poorness of the soil for hickories, seems possible may be the reason for the cessation of bearing.
