In this schedule the crackability of the sample is measured by the weight of first crack and the number of halves. The yield of kernels is measured by the total weight of kernels in the sample. The first crack includes only those kernels that either fall out or can be removed easily with the fingers. The remaining kernels are rescued with a pick or by recracking. In my judgment, the score accurately measures the merit of the samples. In the Mandeville, the large size is measured by the weight of kernels which in part offsets poor cracking quality. Poor cracking is usually caused by the edges of the halves being curved so as to be bound in the sh.e.l.l. Much more testing should be done to determine the value of the schedule.
Opinions regarding the ease of propagation of the b.u.t.ternut differ, but mostly it is considered difficult to propagate, with often complete failure. This merely means that the matter is not well understood. In my own experience I have had just about as many failures as successes, and must confess that I do not have much idea of what has been responsible for either success or failure. Best results have been secured by using inlay or bark slot grafts on stubs about 2 inches in diameter. This agrees with the experience of Mr. Burgart, of Michigan, and Mr. Weshcke, of Minnesota, who report that grafts must be made several feet from the ground and not at the crown.
Shield budding has apparently not been satisfactory. Mr. D. C. Snyder writes that chip budding is more successful. It is recommended by others and I agree that grafting should be done early, just as growth starts rather than later when trees are in leaf. Special care must be used in tying the new shoots of the graft to braces to prevent breakage by wind or birds. The b.u.t.ternut wood is very brittle and the grafts are often lost by breakage. The whole matter of b.u.t.ternut propagation merits further careful study.
b.u.t.ternut varieties may be grafted on black walnut, b.u.t.ternut, or _J.
Sieboldiana_ stocks. Mr. Burgart, Mr. Weschcke, and Mr. D. C. Snyder consider black walnut to be better than the others, giving a more vigorous long lived tree. Varieties on b.u.t.ternut stocks are apparently relatively short lived and _J. Sieboldiana_ stocks have a different growth rate and are not hardy. Mr. Burgart uses bark slot grafts on black walnut seedling stocks, 2-3 years old.
b.u.t.ternut trees on their own roots transplant relatively easily because there is no taproot as with the black walnut and the hickory, and there are many fibrous surface roots that can be lifted when the tree is dug.
Black walnut stocks are not difficult to manage, particularly if the taproots are cut on the seedlings. Culture is no special problem.
Mulching and supplying nitrogenous fertilizer is good practice.
The b.u.t.ternut has the reputation of being susceptible to disease and hence being short lived as a tree. Whether or not this is actually the case is perhaps questionable. Many b.u.t.ternut trees, particularly those in favorable situations of soil and moisture, live to be of large size and old age. Trees on poorer, thinner soils apparently die off earlier than those under better conditions. In any case, it is well recognized that the b.u.t.ternut has a shorter life span on the average than the black walnut, which frequently lives to a large size and old age. There are two common diseases of the b.u.t.ternut. One is leaf spot caused by the fungus _Marsonia_, which defoliates the trees fairly early in the season and probably predisposes them to injury from other fungous attack. This is the same leaf spot that attacks the black walnut leaves. The other disease, which may cause trouble, is a fungous walnut blight known more specifically as Melanconis blight. It has not been established that this disease is an active parasite. The evidence indicates rather that it attacks trees that are already somewhat weakened by defoliation or other injury. It is a fact that many of the dead limbs on b.u.t.ternut trees are found to be affected with the disease. It is a matter of observation that trees growing under favorable conditions are less damaged by the disease than those growing under poor conditions of soil and water, therefore, keeping trees vigorous is good practice.
As with other nut tree species, there are troublesome insects. One of these, the b.u.t.ternut snout beetle or curculio, attacks both the b.u.t.ternut and the j.a.panese walnut. Control has apparently been secured by dusting foliage with DDT. Sometimes the leaves of b.u.t.ternuts are badly distorted with galls caused by mites. The bunchy top or witches"-broom caused by a virus, that is serious on the j.a.panese walnut, _Juglans Sieboldiana_, does not appear to be so virulent on b.u.t.ternut. This, however, is a matter of personal observation and is not based on a thorough study.
In conclusion, let me say that in my judgment, the b.u.t.ternut is worthy of more attention than it has had so far received, particularly by home owners in the northern states who would like to have trees in their yards that will bear nuts under conditions that are unfavorable for most other kinds. If it were publicized that varieties are available that will crack out in halves with relatively little effort, the chances are that with these facts in mind those interested in nut trees would give the b.u.t.ternut much more attention. The difficulty at the present time seems to be related to a lack of knowledge as to the relative merit of different varieties and a scarcity of trees because of difficulty of propagation. If we have time and the chairman will permit, I would welcome comments on the propagation problem and would also like to obtain any information on the merit of the named varieties. Let me also state that if any of you have a sample of 30 nuts of any named variety in this or last fall"s crop that you can spare, I would be much pleased to have you send it to me for testing.
Discussion
MR. STOKE: It grows in New Brunswick, and I have had specimens from north of Lake of the Woods.
MR. CORSAN: They grow at Brooks, Alberta. I have the Helmick and it grows 14 to the cl.u.s.ter, has a thin sh.e.l.l and heavy meat, and the leaves are persistent. They don"t drop off the first of September. That"s the Helmick. It"s grafted on black walnut stock, and the black walnut stock comes up like that (indicating) and the Helmick recedes.
DR. MacDANIELS: The black walnut overgrows it. There are about 40 varieties, and I would like very much to get hold of any of the samples I can get.
MR. CORSAN: Go up to Silver Bay, Lake George, and on the sh.o.r.e there the Indians have bred the b.u.t.ternut, and it"s 10 to the cl.u.s.ter among those trees by Silver Bay, Lake George, New York. Ernest Thompson Seaton and I examined that grove years ago.
DR. MacDANIELS: Wish we had them where we could get at them. Any other comment on the b.u.t.ternut?
MR. McDANIEL: The Helmick is considered to be a "b.u.t.ter-j.a.p" seedling of heartnut, possibly the other parent was a b.u.t.ternut.
DR. MacDANIELS: That is something we will have to decide in the a.s.sociation, whether or not we are going to throw in these hybrids and the heartnut along with the b.u.t.ternuts in standards or try to keep them separate.
MR. CORSAN: Hybrid heartnut cross is very, very superior in every way to the b.u.t.ternut in my estimation, except for hardiness.
MR. STOKE: That is a hybrid. I have it. The Mitch.e.l.l hybrid.
DR. MacDANIELS: The ordinary run of seedlings are not worth keeping, no question about that, and it"s too much work to recover the kernels.
There are several announcements I"d like to make. One has to do with this hall. It is the American Legion hall, which they do not charge rent for. They do, however, and will expect some sort of a token of appreciation that will be fairly substantial. There is no provision for that in the budget, so any of you who are feeling a little mellow and flush, if you want to approach the treasurer with a contribution towards the use of this hall, that will be appreciated; otherwise, the matter will have to be settled out of the treasury as such.
MR. CORSAN: How about a dance in this hall?
DR. MacDANIELS: If we stay over, we might do something like that.
Then there is the other matter, and that is the prize for the proposed Carpathian walnut contest. There is no prize money available at the present time. If any of you wish to provide a first, second, or third prize, we might even tag it with your name, if that would be possible.
I think probably they will be able to get some publicity backing through farm papers and what not, but still if we have a backlog of prize money, why, that"s much to your advantage.
Do you want to say anything further on that, Mr. Chase?
MR. McDANIEL: Mr. Sherman, I believe, has a word.
MR. SHERMAN: Not in this connection.
MR. PATAKY: Do any of the members here have sh.e.l.led b.u.t.ternuts or hickory nuts that they would sell? If they do, I"d like to get their names and get in touch with them. I do have a demand for some sh.e.l.led b.u.t.ternuts which I have trouble getting, and I do have trouble getting sh.e.l.led hickory nuts. It is for the Wideman Company out of Cleveland. I got sh.e.l.led b.u.t.ternuts before the war, but since the war they don"t have the trade, but if they could get them, I think that would be the company that would take them. The Wideman Company of Cleveland, Ohio. They are a big wholesale house. Write to Christ Pataky, Mansfield, Ohio, R.D. 4.
MR. KINTZEL: Do you sell them in the sh.e.l.l?
MR. PATAKY: I do sell them in the sh.e.l.l, too, but there are a lot of people who won"t buy them in the sh.e.l.l. We do have a demand for them, not too much on the b.u.t.ternut, but we do have for hickory nuts. I think we could sell a lot more hickory nut meats than hickory nuts even at the difference of the price. I know the price was quite high before the war.
They paid somewhere around a dollar a pound before the war for sh.e.l.led ones, and we even sold them at a profit for that, and we haven"t been able to get any since the war. I don"t know what happened, whether the kids are too busy playing basketball or football.
DR. MacDANIELS: They get too much for mowing lawns.
MR. WEBER: There is a nut crackery at Mitch.e.l.l, Indiana. The man who cracks them cracks hickory nuts and puts them out in his name, John Eversol. Mr. Wilkinson can tell you exactly what his name is. He was down there last year. He is cracking walnuts, and in addition cracks hickory nuts and puts them in fine shape.
MR. CORSAN: Isn"t it true that nuts have more Vitamin E than any other food in the world, and isn"t Vitamin E the greatest antidote against anemia?
DR. MacDANIELS: I wouldn"t know. You have a medical man here?
DR. WASHICK: I don"t think you are right.
MR. CORSAN: In the West they say Vitamin E is a cure for anemia and they are having wonderful success, and they claim there is more vitamin E in nuts than any other food. I don"t know, they are keeping me alive.
~Editor"s Note~: Green walnuts are rich in Vitamin C. See 1942 Report, page 95.
DR. MacDANIELS: You are Exhibit 1.
I think Mr. Salzer has slides he wanted to show this afternoon.
MR. SALZER: I had a few. Perhaps we can use those blankets and just fix up, perhaps, a few of these windows in front, and I think we could probably show the slides.
DR. MacDANIELS: If you can leave the blankets here for a short time, we will get them later.
Any other questions?
