CONCLUSIONS.
The season was so extremely dry that the practice of planting root grafts as soon as made did not prove successful. However, work done in other years indicated that in normal seasons this may be done with considerable success. Placing the grafts in a greenhouse either in earth or decayed sawdust gave encouraging results, but when transplanted in the nursery the grafts could not withstand the unusually dry and hot weather. The black walnut proved to be the best stock for the Persian walnut and two buds to the cion are required. Grafting wax should not be used if the union of cion and stock is to be covered with earth; this point was clearly proven in previous years.
[The foregoing paper, read by title, was the subject of a verbal report by Prof. Lake, who said further:]
Prof. Close performed considerable work in topgrafting and budding on three and four year old stocks. The top grafts were a failure. The buds survived, and were in good, strong condition October fifteenth. That was on Persian walnut and pecan, about half and half.
Mr. Pomeroy: Did he bud on black walnut stock?
Professor Lake: Yes. It was a little higher than a man, and had been cut back to about three feet. The crown grafting was fairly successful, but would have been much more successful, had they used something to cover the grafts.
Mr. Pomeroy: How long should the paper sack be left?
Professor Lake: It would vary with the season and activity of the stock, ten days to two weeks.
President Morris: I wish you would try further experiments in rooting scions in warm sand in the hot-house. I believe that in some stage you can probably root those cuttings in moist sand in the hot-house, heated beneath; and if you can do that, it is going to settle the question very largely of hickory and walnut propagation. What do you think about that, Professor Craig?
Professor Craig: I am not very optimistic about the possibility of that. I find it very, very difficult to get roots to develop from Hicoria. You can get the callus almost every time, but it is very difficult to secure the development of roots afterwards.
President Morris: How about getting callus by three months, we will say, in storage?
Professor Craig: We would have the same trouble. They would develop adventitious buds very poorly. Doctor Morris has sent us from time to time some samples, and we have been making experiments. I have used different methods and different propagators. We have one propagator, who has been most successful usually in striking difficult things, and he has absolutely failed in this one. I may say that our facilities for propagation are not ideal at the present time, but we shall have in a short time a good propagating house with properly regulated benches, as to bottom heat and overhead ventilation and all that; and we shall, of course, keep up the experiments.
President Morris: In my experiments, I grafted hickory scions on hickory roots, and the whole thing, root and scion, lived until the root sent out adventitious buds, yet in that case we did not get union between the top and the stock. How do you explain that, Professor Craig?
Professor Craig: I don't explain it.
President Morris: Are we likely to have success along that line by some modification of the plan?
Professor Craig: I couldn't say. You can keep the cuttings alive for three or four months.
President Morris: They were in damp rooms, exposed to light, right in the window.
Doctor Deming: Professor Coville has made some experiments in rooting hickory cuttings for me. Professor Coville is the one who has made such a success of blueberry culture. I sent him some cuttings, and he reports as follows:
"Two experiments were tried with the hickory cuttings received from Dr. W. C. Deming on January 5, 1911. In one experiment some of the cuttings were placed in a glass cutting bed in live sphagnum covered with sand, the upper ends of the cuttings projecting from the sand. The atmosphere above the cutting bed was kept in a state of saturation by a covering of glass. The bed was kept shaded and was subjected to an ordinary living room temperature varying from about 55° to 70°, or occasionally a few degrees higher.
On January 11 the cambium ring at the lower end of the cuttings had begun to callus. On February 17 the upper bud on one of the cuttings began to push. Later some of the other cuttings began to swell preparatory to the development of new growth. All the cuttings, however, finally died. It appeared from their behavior that the temperatures to which they were subjected were too high for their best development.
In the other experiment the cuttings were placed in sand without sphagnum in a greenhouse at a temperature ordinarily of 50° to 65°, rising occasionally, however, on still, sunny days to 70°. After a few weeks, these cuttings were well callused and the buds began to swell slowly, exposing first their green bracts, and later on some of the cuttings the green compound leaves, pushing out from among the bracts. These cuttings also, however, finally turned black and died, but not until after the first of April.
The experiments showed that hickory cuttings, when taken at a suitable time of year and exposed to conditions suited to other hard wooded plants known to be difficult to root, retained their vitality and passed satisfactorily through the stages preliminary to rooting. While no actual roots were secured, the experiments suggest that the rooting of hickory cuttings is not beyond the possibility of attainment.
As the basis of an experiment this winter, I suggest that you select half a dozen twigs that you are willing to sacrifice on some good variety of hickory, and remove a ring of bark at a distance of 4 to 8 inches from the top. The ring of bark removed should be about half an inch in length and its upper end should come about a quarter of an inch below a bud. At the present season the bark will not peel from the wood. It will, therefore, be necessary to scrape it off, so as to leave nothing but the wood on the girdled area. The bark should be cleanly cut at each end of this area. I hope that we shall still have sufficient warm weather to induce the formation of a callus on the cambium at the upper end of this ring.
Later in the winter, some time in January, you can cut off these twigs and send them to me, packed as those were last year. The cutting is preferably made just below the ring. I would prefer that all the wood from the ring to the tip of the twig be of the past summer's growth. We can try, however, twigs containing two seasons' growth, if the others are not easily available."
President Morris: That is a suggestion, you see, of apparent value, because it has succeeded with blueberries,—this method of cutting off a ring of bark before the leaves are shed, allowing a ring to callous, then later cutting off this prepared twig and subjecting it to methods for striking roots. It is an extremely interesting suggestion. Just as soon as I heard of this procedure, I went out and prepared about fifty hickory and walnut twigs myself, but that was this autumn, and I haven't cut them yet for the experiments in rooting. Has anyone had experience along this line?
Mr. Collins: I saw an experiment in rooting, and I am prompted to ask if anything has been done along this particular line. The method employed was this. The twig was partially cut from the branch, perhaps cut three-quarters of the way through with a slanting cut. It was then bent a little, and a little sphagnum put in the cut, then a ball of sphagnum was wrapped about the whole cut area, and it was tied with twine, and that was kept wet for several months, I think, until, finally, new roots pushed through and appeared on the outside of this ball of sphagnum.
President Morris: I read of that. It was published in a government report.
Professor Collins: It was on the rubber plant.
President Morris: I tried it at that time on the hickory. The difficulty was in getting my men sufficiently interested to keep the sphagnum wet all the time. It promised something. The rubber plants, perhaps, would lend themselves more readily to such a procedure than the hickories, because most of the rubber plants are air plants, anyway. All of the Ficus family depend so little upon the ground for their nourishment.
Professor Collins: I have seen that worked very successfully.
Professor Lake: You don't know how successful the callousing has been?
President Morris: They calloused all right.
Professor Lake: How long did it require?
President Morris: I don't remember. It was a good while, longer than I anticipated. I don't think there was a callus on the hickory in less than thirty days. The butternut and black walnut hardly showed any callus at all after keeping the sphagnum wet as long as my men would do it.
Professor Lake: At what time was the ringing done?
President Morris: The leaves had fallen this year. Professor Coville suggested that it be done before the leaves had fallen. But the hickory will callous after the leaves have fallen. It seems to me hickories are at work all winter long. They have a free flow of sap in January, and any warm day in January they will be like a maple tree, almost, if they are cut. I have grafted them at that time.
Mr. Brown: Can anyone give me any information on grafting chestnuts?
Mr. Rush: I have been very successful with the grafting of the chestnut. It is just as simple as grafting other fruit, except the Persian walnut. Tongue grafting and cleft grafting is very successful. There is no particular secret in connection with grafting chestnuts.
President Morris: Personally, I found it difficult for two or three years, but now I can graft the chestnut about as readily as I can graft the apple. There is no difference in methods. It seems to me from my present experience that one may graft or bud chestnut by almost any of the accepted methods pretty freely. What has been your experience, Mr. Littlepage?
Mr. Littlepage: I haven't been experimenting with the propagation of the chestnut yet. I am getting ready. I have three or four thousand seedlings, a few of which will be ready to graft next year. I have twenty acres of the Paragon chestnuts growing.
President Morris: In chestnut grafting, we will find that one kind does not graft or bud readily upon another kind, perhaps. For instance, there is some antagonism between the American sweet chestnut and Asiatic chestnuts. There is some antagonism between Asiatic and Europeans; there is little between Europeans and American sweet. These antagonisms are something that one has to learn from experience at the present time, because I doubt if we have had enough experience to know just where we stand on this question.
Professor Collins: Doesn't there seem to be antagonism between eastern Asiatic other than Japanese and Japanese?
President Morris: Yes; the Koreans of both kinds, the north Japanese of both kinds, and the Manchurian chestnut are the five that I have experimented with in grafting, and none of those grow so well on American stock as they should.
Professor Collins: I mean to say between the Korean and the Japanese.
President Morris: There is less antagonism. You can graft the Korean upon the Japanese and the Japanese upon the Korean very readily. They have very much the same texture of wood, the same character of buds and bark.
Professor Collins: Is there any antagonism between eastern Asian and Japanese?
President Morris: I don't know that my experience has been extensive enough to say. My men have put on perhaps two or three hundred grafts back and forth between these kinds, the customary accidents have happened, and we have about given up trying to do much grafting of Japanese on American, but still plan to graft Japanese back and forth upon each other, and we are now planning to graft European and American back and forth upon each other.
Mr. Brown: What about the position of the graft?
President Morris: I don't know, Mr. Brown, if there is very much difference. I haven't found very much. I have grafted all the way from the root to the top.
Mr. Rush: It is better on top. Sometimes the grafting has an effect upon the stock just at the union. If it is budded low, it blights. The bark gets loose. All those that are grafted high are doing remarkably well.
President Morris: The next on the list is Doctor Deming's paper on "Nut Promotions."
Doctor Deming: I will read first a communication from Mr. Henry Hales of Ridgewood, New Jersey.
HALES' PAPER SHELL HICKORY.
My shagbark (paper shell) hickory tree was on my farm when I bought it in 1868. It had been noticed by the neighbors as bearing a fine nut and was watched by them for the nuts, but they did not appreciate the value of them. The late Andrew S. Fuller had not seen them, but asked me to bring him a few. When he saw them he was surprised and at once pronounced them the finest hickories he had ever seen, and named them "Hales' Paper Shell." The hickory is one of the most valuable of North American nuts. It is of a variable nature. I have over twenty old trees on my place, and no two bear nuts of the same shape or size, and although some neighbors planted some nuts from the old tree and produced fruit from them they were only ordinary sized, so that it is necessary to propagate them to retain their value. About 1880 Parsons & Son, of Flushing, N. Y., grafted some in pots under glass, from which trees these nuts sent are the product. The fruit is fully as fine as the original tree. Prof. C. B. Sargent of the Arnold Arboretum has taken great interest in the nut. I have two trees grafted on wild saplings by Jackson Dawson near bearing size.
Those are the only trees successfully grafted, out of thousands done in the North outside, from which I am afraid grafting outside in the North is a failure on hickory stocks. There may be a better chance on pecan stock, which I have not thoroughly tested under favorable circumstances. I have been sending northern pecan nuts and had them planted, and sent scions for working on them in the South; had some failures from natural causes. Simpson Bros. of Monticello, Florida, have had fair success there. My share of two year old trees are on the way here. Of the value of these nuts too much cannot be said. Mr. Fuller ranked them superior to the Madeira nut. It has remarkable keeping qualities.
It has taken from eighteen to twenty-five years for my grafted trees to come into bearing.
I earnestly hope that with the knowledge gained so far, the means of propagation on a large scale will soon be discovered and successfully carried on. What a gain it would be to the wealth of our food production and luxury. The American hickory would then stand highest on the list of our native nuts.
President Morris: Are there any comments upon this paper of Mr. Hales? So much is being said about the Hales hickory, it seems to me that possibly we ought to put on record some thoughts in the matter. Mr. Hales is entitled to more credit than any other man for bringing forward the development of the shagbark hickory, and his enthusiasm was based upon this remarkable nut on his grounds. It is a very large nut, and, like all large nuts, is much coarser in character than small nuts, and, like all large nuts, lacks delicacy of flavor that we find in small nuts. It is thinner shelled than most of the shagbarks that we would see in many days spent in the woods, but when we have for comparison some smaller nuts, we find shells very much thinner than the shell of the Hales. The Hales, like many other large hickories, keeps much better than the small hickories of finer texture and more delicate quality, and it may be very good at three years of age, while some of the most delicious of the smaller, more tender and delicate nuts are spoiling at the end of six months. I don't know that Mr. Hales would take exception to my way of stating this, but it seems to me that he ought to feel that we give him all honor, that we think it a remarkable nut, that it is a nut, because of its size and features, worthy of the enthusiasm he gave it. There is apt to be some misunderstanding as to the exact position this holds in relation to other shagbark hickories.
Mr. Littlepage: What is its bearing record as to quantity?
President Morris: The tree has been cut so much for scions that it has never had a fair chance. It is a prolific tree. It is well worthy of propagation.
Mr. Littlepage: It is, perhaps,—judging from looking at it—a very fine shagbark for commercial purposes. Isn't it true that within the next ten years there will, in all probability, be a complete reversion in the mind of the nut culturist as to the kind and quality of the nut he will propagate. I will supplement that by saying that heretofore, both in the pecan and other nut fields, the whole tendency has been toward something big. Now, the wise fellows in the South today are beginning to get away from that. I have made many trips down there, and I find there is a very changing sentiment. I want to say that in my observation the future price of the various nuts of the country is going to be determined by the price of nut meat; that the meats are going to be put on the market, and while there will always be plenty of nuts marketed in the shell, the price of the nut meat will be the dominant factor. I was walking down G Street in Washington the other day with an ex-United States Senator, and ex-member of Congress, and an ex-Governor, and they passed a nut store, and saw in the window some nuts, also a big box of nut meats. Everyone went in, and all passed up the nuts and bought the nut meat. That expresses, to my notion, the tendency that is coming; and that thing is going, then, to determine very largely the question of quality.
President Morris: I think we certainly are going to have a complete change in ideas about raising nuts. We are going to raise big ones of the kinds where everybody will buy one pound and nobody will buy two pounds. We are going to raise nuts that will appeal to the people who purchase things in the open market, and who never in their lives get hold of anything that is good. We are going also to raise nuts that will appeal to connoisseurs, and that will be bought by people who know one work of art from another. In other words, we are going to make the progress in nut culture that has been made in other fields of horticulture. At the present time, if one could raise a pear as big as a watermelon and tasting like the rind, that would be the pear that would sell in the market. But the connoisseur buys the Seckel in place of it. When there is a pear like the Kieffer that will fill the top of the tree so there is no room for leaves and branches, the market men are going to raise that pear. But when we go into the market, we go around a block to escape the place where they sell the Kieffer pear, and we buy the Bartlett. We have precisely the same problems in nut culture.
Mr. Pomeroy: I have been thinking some on this line. I have spent a good many half hours in the last four or five years with an old German in Buffalo. He has a stand on one of the big markets. I find that he has a whole lot to say in regard to what the people buy. He has found this out, and he has been there a good many years. He says, "I have been getting black walnuts from the same farmer boy for six or seven years. They are fine; try one." He has learned something about the different trees throughout that section, and about some nuts that are being shipped in, and he can tell the varieties. He has customers that do come back after the second package of nuts. He is trying to keep those customers one year after another. He is creating the demand. When I was a youngster, if I could have received the prices for black walnuts and butternuts that youngsters get now, I would have thought I was a capitalist. Butternuts are retailing at two dollars and two dollars and a half, and black walnuts the same.
President Morris: We have got to get away from the idea that we are going to find the best hickory nut or the best walnut or the best nut of any kind in the largest nut. Nature spreads out just so much material in the way of flavor and good quality of a nut, and if it is in a large nut, those good qualities are spread out thin; if it is in a small nut, they are concentrated.
Professor Lake: I wish I were as optimistic as Mr. Littlepage in this matter. That is because he has been studying all nuts for twenty-five or thirty years, and I have only been dabbling around in Persian walnuts for about twenty years. I have been dabbling with apples twenty-five or more years, and the real connoisseurs of the apple have been telling us during that time that the Ben Davis would be wiped out inside of ten years. I heard that twenty years ago. I believe that there are more Ben Davis apples being consumed by the public today than any other one apple. Notwithstanding that, every man who knows good apples goes out and decries it. It is because that apple can be grown anywhere by anybody at any time, and will be eaten by the people. The kind of nut that is going to make the money the next twenty-five or thirty years is the nut that is prolific, of fair quality, that can be grown by any man, and that has a fairly good appearance. I believe that the process of educating the public on the matter of quality is going to be tremendously slow. It is not always the case, however, that the smaller the size, the better the quality. A medium size would be better. The Yellow Newtown is quite a large apple, and it is superior in quality to the Winesap.
President Morris: I was stating a general rule.
Professor Lake: I fear we aren't going to be able to educate the people. How many people who eat nuts know anything about their quality? Dr. Morris has got the ideal of the best nut in walnuts, for instance, the French Mayette. That is the connoisseur's choice. I know of many people who will tell you very frankly they prefer the American grown Franquette, which is much more starchy in make-up and much less nutty.
Mr. Littlepage: I think there is a great deal in what Professor Lake says. I am not sure he has got the cause of the facts he states. One reason why the Ben Davis is being planted is, as he stated, that it will grow almost anywhere; but the reason the public accept the Ben Davis is because they can't get enough of another at a reasonable price. There isn't any doubt that if there were plenty others at a reasonable price the Ben Davis wouldn't be used at all. We hear so much today about this high cost of living. Of course, there are artificial conditions that have contributed to this to a greater or less extent; but the principal element is that we have come up against the problem of feeding the great American public, that has grown faster than the facilities have grown. The time for low priced food products is gone forever. Yet there is a good deal in this commercial phase of it.
President Morris: The Hales hickory is going to be like the Ben Davis apple, one of the very most popular in the market.
Doctor Deming: I will say regarding the retail price of nuts that in New York City shelled filberts are priced at $1.25 a pound, shelled almonds $1.00, ordinary run of hickories and chestnuts in the shells twenty cents, black walnuts in the shell twelve cents.
President Morris: Hickories will give somewhat over fifty pounds to the bushel; black walnuts about forty. If we make a rough estimate of fifty pounds to the bushel for shagbarks, and forty for Persian walnuts, we will probably have a good fair average.
NUT PROMOTIONS.
By W. C. Deming, New York.
Promoters attack their quarry with a two-edged sword; one edge is what they say, the other what they leave unsaid; and both edges are often keen. What they say generally has a foundation of truth with a superstructure of gilded staff. You must knock over the staff and examine the foundations to see if they are laid up in good cement mortar or only mud. Sometimes they are honestly laid but your true promoter can no more help putting on his Coney Island palace of dreams than a yellow journal reporter can help making a good story of the most everyday assignment. I suppose he takes a professional pride in his decorations, even when the real facts themselves are good enough. Or even, in his enthusiasm, half believes, and fully hopes, that what he says is true. So you never can say that because of the evident gilding there is nothing worth while beneath.
What the promoter does not say it is absolutely necessary for the safe investor to find out. Deductions from experience in general, and from knowledge of the business in particular, will help and, when these favor further investigation, there are two essentials for a wise decision. First, a study of the records of the promoters, and second, a personal examination of the property. If these can be thoroughly made, and the results are satisfactory after a suitable period of mental incubation, if the prospects will stand the candle test for fertility, you may put some money on the chance of a good hatch; remembering, too, that many a good hatch afterward comes to grief with the pip.
Some promotions are conceived in iniquity, some in drunkenness and folly and some are abortive from incapacity. Your legitimate and well-born, well-brought-up promotion, fathered by ability and mothered by honesty, it is your problem to recognize, if that is what you are looking for, and to avoid the low-born trickster or incapable. No one can tell you how to do this any more than he can tell you an easy way to graft hickories.
The northern nut grower is not yet bothered with northern nut promotions. At most he is called on to discount the statements of sellers of trees, and that a little, not too expensive, experience will teach him. The West is apparently too busy selling fruit and fruit lands to lay out nuts to trap eastern nibblers. But the allurements of pecan growing in the South are spread before us with our bread and butter and morning coffee. The orange and pomelo properties have been banished from the stage, or made to play second fiddle, and now we see in the limelight the pecan plantation, with a vista of provision for old age and insurance for our children. And there shall be no work nor care nor trouble about it at all. Only something down and about ten dollars a month for ninety-six months. And the intercropping is to more than pay for that. It is indeed an enticing presentation.
Although we have as yet no northern nut promotions we may expect the time when the sandy barrens of the shore and the boulder pastures of the rock ribbed hills will be cut up into five acre plots and promoted as the natural home of the chestnut and the hickory, holding potential fortunes for their developers. I hope it will be so for it will postulate a foundation in fact. But the chestnut blight and the unresponsiveness of the hickory to propagation as yet hold up these future camp followers of the northern nut growing pioneers. So that for the present there is only the sword of the southern pecan promoter to parry.
It would be a work of supererogation and effrontery for me to attempt to treat this subject in particular since it has been so clearly and ably done by Col. C. A. Van Duzee of St. Paul, Minn., and Viking, Fla., from the standpoint of long experience and full knowledge. His paper should be read by all interested persons. I am permitted to make the following quotations from it:
"The pecan as an orchard tree has recently been discovered and its history has not been written. The record at present is largely based on scattered individual trees growing under abnormal conditions which, as a rule, are favorable....
"Calculations and deductions based upon these results have been made which are fascinating, but they are utterly unreliable when applied to orchards of other trees in different localities growing under totally different conditions?...
"No one knows what a pecan orchard grown under such conditions is going to do."
Col. Van Duzee, however, expresses firm belief in the success of pecan growing under proper personal supervision.
It all comes down to the question, "Can you or I hire our business done for us, never go near it ourselves and expect others to make a success of it for us?"
And yet, when all is said, I confess that I have been tempted by my faith in the present and future of pecan growing in the South. I might have invested were it not for my firm belief that, in nut growing, the North is but a few years behind the South, and that I wish to devote my resources and my energies to having a hand in a development which, I share with you the belief, is to be of inestimable benefit to the human race. We can picture the day when our dooryards, our roadsides, our fields and hills shall be shaded by grand nut trees, showering sustenance and wealth on our descendants, and all people, and bearing the names of their originators; when the housewife of the future shall send her wireless call to the grocer for a kilo of Hales' Papershells, the Rush, the Jones, the Pomeroy Persian walnuts, the Black Ben Deming butternut, the Craig Corean chestnut, the Morris Hybrid hickory, the Close black-walnut or the Littlepage pecan.
President Morris: It is a very timely paper. The number of promoters we find in connection with any subject furnishes an index of the fundamental value of the original proposition. The number of dishonest people, the number of fakirs that are now promoting development schemes in connection with the pecan indicates that down at the bottom somewhere, there is a real gold mine. We will go on to Mr. Roper's paper.
