What fertilizer, or manure, has been used in the particular case, or none?
Is there in the nuts, leaves and bark any sign of cross-pollination?
Regarding the grafting and budding I found that the local nut-growers had not the slightest idea how to go about it. They also did not care to prevent their walnut trees from cross-pollination.
Soon I found that there in Galicia alone could be found several hundreds of varieties of Carpathian English walnuts. Anyway till 1935, I sent to Toronto 200 varieties of the Carpathians.
Some of those English Carpathian walnuts were 2-1/2 inches long, or five nuts to a foot; others were only one third of an inch. Some very small Carpathians produced nuts in clusters, like grapes. In some Carpathians it was possible to detect cross-pollination with Asiatic walnuts by their harder shells, by partitions, by the shape of nuts, by the construction of the leaves and their odor, and in some cases by the color of bark.
By kernels all the Carpathian halfbreeds are English walnuts, differing group from group by the taste. I remember that only in 1898 in the bourg of Loubni, and in 1933 in the City of Kolomyja I came across two trees which resembled our black walnut. In both towns some people used to live in America, and coming home they could bring with them some American nuts.
In the region around Kossiv I came across groves of American black walnuts and butternuts. Those trees were planted there by the Austrian Government 75 or so years ago. Of course they did not cause all the hybridizing I mentioned above. Maybe the Asiatic nuts were brought in Eastern Carpathians when the Tartar hordes crossed the mountains in the region of Pokouttia (Kossiv) in the year 1242.
Not far from Kossiv, westward, in the village of Kosmuch in the Carpathians 2500 feet above sea level I found English walnut trees of small size (15 feet tall, 6 inches thick) with light gray bark, producing 2 inch long nuts of speary shape, like our Canadian butternuts but of English Walnut shells and kernels. The kernels were tasty. There was no question but that they were halfbreeds, English plus Mongolian nuts.
There in Kosmuch, not far from the historical Tartar Passage, through which in 13th century Ghengis Khan hordes invaded the Danube plains, in winter the temperature falls to 45 degrees below zero. Owing to the hardiness of the strain and pleasant taste of the nuts I picked up about 10 pounds of them to be tried in colder parts of Ontario, (and some of them already are bearing north of Toronto and true to the type.)
I called the nuts Hutzulian Pointies, as they grow in Hutzulia the country of the Ukrainian Mountaineers.
