I had one tree of the Sherwood butternut, planted in 1938, which died last winter as a result, I believe, of a heavy infestation of oyster shell scale which I did not control soon enough. Sherwood bore early and heavily. The nut was extremely large but did not crack at all well.
Persian walnut. Only one grafted tree, a Broadview, from Mr. Gellatly, planted in 1942, transplanted in 1944. Has been hardy, but has just begun to make really good growth, this year. Has not borne.
Filberts. I have planted four of Mr. Gellatly's varieties, namely Craig, Brag, Comet and Holder, as well as Barcelona, Cosford, Medium Long and Buchanan. Craig and Brag are the only ones which have borne. Trees of those varieties planted in 1942 bore their first crop in 1946. They have very few nuts on them this year. All varieties seem to be winter-hardy in the wood. Craig, Brag and Comet, the only ones which have borne staminate flowers do not seem too hardy in the catkins however. Nearly all were killed, last winter, although the temperature scarcely went as low as zero. Mr. Gellatly states that their catkins survive much lower temperatures than that in the west. Some other factor than low temperature probably is accountable. (See paper by H. L. Crane in this report.—Ed.)
Cosford, Medium Long and Buchanan were planted in the fall of 1946, and hence it is too early to have any information on their hardiness. They survived their first winter in good condition and have grown vigorously this summer.
Hickories. Only three grafted trees surviving.
Pleas hybrid. One tree, planted in 1938, has been perfectly hardy, having come through several severe winters without any sign of injury. It has made good growth and has developed into a fine shade tree for the lawn but has not borne. It has had many staminate catkins for several years.
Barnes. One small tree, planted in the spring of 1946, has made slow but healthy growth and appears to be hardy thus far.
Miller. One tree, planted in 1946, is still living but very weak.
In addition to these named varieties I have a number of seedling black walnuts, butternuts and heartnuts, which I hope to topwork to named varieties; also two seedling pecans which are making surprisingly good, thrifty growth. The pecan seedlings have been quite hardy.
