ly outgrows the latter. The reverse is the case when Japanese heartnut, Japanese butternut, or hybrids of either are grafted on the black. So far I have not found one good butternut worthy of naming, but there is one Japanese butternut that grows in clusters of 17 or even more that has a very thin shell; it is the Helmick. I have, however, very many named as well as unnamed black walnut seedlings that are very excellent nuts. This has been a very cold summer and I cannot state yet as to the maturing of the larger black walnuts, as they require a long season to mature properly. Pecan and hican trees grow well at Echo Valley and the small twigs harden up so that there is never any winter killing but the nuts do not fill well; in consequence I am using the trees as stocks for grafting with good shagbarks. The Weiker hickory ripens nicely with me and I consider it one of the best varieties in every way. Self-fruitfulness in the Winkler Hazel By Dr. A. S. Colby University of Illinois, Urbana, Illinois To insure fruitfulness in nut plants it is generally recommended that more than one variety of each kind be planted in reasonably close proximity to help in bringing about cross-pollination. Then, with other conditions being favorable, the grower would be more certain of good yields of well-filled nuts. With specific reference to the filbert, the literature contains references to the effect that provision for cross-pollination is essential. However, one exception is listed. In the report of the proceedings of the 26th (1935) annual meeting of the Northern Nut Growers' Association, D. C. Snyder of Iowa says on page 47, "The catkins of Winkler always come through the winter bright and the variety can be depended upon to bear without other varieties near for cross-pollination." The writer has been interested in this subject for several years. The question arises; how near were Mr. Snyder's Winklers to other varieties and in what direction with reference to the prevailing winds? It is not known just how far filbert pollen may be carried and still function. A planting of Winkler filberts consisting of about 30 bushes was set on the University Farm at Urbana in 1940. Crops have been borne annually since that time. The planting was isolated from other filberts to the southwest by about one-fourth of a mile. In an effort to determine whether the variety was self-fruitful, plants were dug in the early winter of
