Our success with butternuts has been due, very largely, to the method we adopted some twenty years ago and might be summed up in the following report. From one hundred pounds of butternut seed, which we secured in the fall of 1914, and which we planted the same season in October, we got in the following year a splendid stand of seedlings which gave great promise the first summer. During the winter of 1915 a great number of those seedlings were partially or altogether destroyed, through the climatic conditions of the country. But quite a number of them stood up in splendid condition. After about three years we eliminated everything that did not stand up 100 per cent and show a splendid growth. We had in the neighborhood of fifty trees and thus, through a survival of the fittest, the foundation of this industry became established. We distributed perhaps twenty or more trees to the Experimental Farm and other places. These have all stood up, as far as I can learn, with splendid success. This left about thirty of the original trees in our nurseries. These thirty have never shown any sign of frost killing nor are they in any other way affected.
Our trees commenced to bear in their sixth year, in 1920 and have increased in size and fruiting year by year, until today they are about thirty feet high with a spread of about thirty-six feet and are without question the most beautiful row of trees west of the Great Lakes. We have grown at least one hundred thousand trees from the nuts taken from these trees, which have been distributed over a very wide territory, reaching from the northern part of Ontario to the Rocky Mountains. Many of our customers have now their own trees bearing. In addition to our selling the trees, we offer to our customers one two-year-old butternut or horse chestnut with each ten dollar order sent in. We took this method to get our nut trees into the hands of a great number of the people.
We have followed practically the same line with black walnuts, but with less success than with butternuts, as a very much greater percentage of the black walnuts went down. Notwithstanding that we have a number of trees which have survived in splendid condition. One of these is bearing for its second year and one other is just bearing for the first time. However, we have a good deal of hardy wood, as our trees are growing bushy and we intend to use the butternut seedlings for stocks on which to graft the black walnut. By this method we will not have to wait so long to get a good supply of trees. There is no question whatever about the future success of the butternut, as we have this year the third generation of them bearing, which is ample proof that they have become entirely acclimated. The butternuts grow fully as large as in eastern Canada, as do also the black walnuts, and as far as I can see the quality is equal if not better.
In addition to the butternut and black walnut, we have made a complete success of the horse chestnut. Ours were planted in 1914, and commenced bearing about the same time as the butternut, and we have grown great crops of nuts continually from that date to the present. We are also trying out the heartnut, both from young trees and from seed. Out of three different plantings that is planted the same year but in different sections, one planting of six trees has stood up completely for the last three years, whereas the other two freeze back a little. In addition to these we are growing from seed the filbert, which seems to be hardy, but is not old enough to fruit yet. However, there is no question in my mind whatever that we shall succeed with all those different trees, following our own method of only using wood and seed from those trees which are proof against the most severe climatic conditions. We used this same method thirty-five years ago in laying the foundation for fruit growing. Out of twelve thousand of the hardiest fruit trees that we could buy from Dakota and Minnesota, after three years we eliminated all but fourteen trees. These were divided between standard apples, crab-apples, plums and plum hybrids. By using northern Russia plum seed and Siberian crab seed for roots, we have been able to lay a foundation for fruit growing in this western country that will live long after we are forgotten.
From Vera Nekiassena
Turkestan
My opinion is there are two kin species growing in Turkestan—Juglans regia L and J fallasc Dode; the first in the Kopet-Dag, the second in the Fansha mountains, in guissar and Darwas. The J. regia is further cultivated in Turkestan gardens and in the Lowawschan Valley. The J. Kamaonia Dode is occasionally to be observed likewise in gardens. I did not chance to see it personally and am in possession of only one of its nuts. Both species (the J. regia and the J. fallasc) produce a great variety of nuts as to shape, thickness of shell and size of kernel. Both these species have been united by some authors (Mr. M. Popof in Bull. of Applied Botany of Genetics and plant breeding XXII N3 (1929), p. 294) into one—that of J. regia but always distinguishing the Kopet-dog nuts in the jsp. turcomanica Popof; difference between them being certainly esctant. The number of leaflets of the J. fallasc amounts to 2-4, they are rounder and more obtuse, the shell of the nut is thicker and also rounder and smaller. The number of J. regia leaflets is 3-5, they are narrower and more pointed (lance shaped), the nuts more elongated, larger and their shell thinner.
Having been for my part mainly occupied with the geographical distribution of nuts without regard to the variation of the fruit shape, I would recommend you to apply for a choice of nuts to Mr. Gursey, (Caucasus, Pjabigorsx), who is making a special study of the problem.
For cultivation in the north you will be interested in J. Manshurica originating in the Far East and very hardy. It is cultivated and produces fruit in Leningrad, young specimens of it were planted on the Solovetsky Islands in the White Sea and there outlived excellently.
Concerning the list of trees appended to your letter, I can give you the following information.
