For the benefit of those new members who are not familiar with my nut tree plantation at River Falls, Wisconsin, I wish to explain its geographical conditions. Situated in the 45th parallel, longitude 92-1/2 deg., about 860 feet above sea level, this is a very severe climate for growing most species of nut trees. Fortunately, I did not realize that fact 30 years ago, and I learned a great deal about the hardiness of many species and varieties and the difficulties of growing them before I was convinced of it. My optimism in those years so ruled me that I was influenced by it to try out such tender species as almonds, English walnuts, filberts, pecans and chestnuts, along with hardier types such as butternuts, black walnuts, hicans, hickories and hazels. To give you a rough idea of the testing I did, I will mention some of my work among hickories. I was fortunate enough to have a forest of bitternut trees on my land. It is a well-known fact that, at least temporarily, these bitternut hickories lend themselves well as grafting stock for many superior varieties of hickories, hicans and pecans, although the last species seldom is considered permanently compatible with bitternut. The number of varieties I tested on bitternut stock is roughly about 75. During the years since I started such grafting, most of these have been lost by natural elimination, lack of hardiness or incompatibility. Those varieties which on my place have proved hardy and compatible with bitternut stock for at least ten years are: Bridgewater, Cedar Rapids, DeVeaux, Glover, Kirtland, and Weschcke. Those which have endured well on this stock for from 6 to 15 years are: Barnes, Davis, Fox, Leonard, Milford, Netking, Platman, and Taylor. Among hybrids which have stood for 10 years or more, there are: Beaver, Burlington, Laney, Pleas, and Rockville. Of pecan, there are Hope and Norton. There are a few other survivors of whose identity I am not certain, as they have not yet fruited. This does not mean that all of those listed have borne, but only that the identity of some of the survivors can not be established without such verification.
