eciable amount since 1937. Since the tree yielded good crops in 1942 and 1943, we are now in a position to report further on the Macedonia walnut. Based on cracking tests of nut samples, the average nut weight and kernel percentage were 16.8 grams and 28 percent in 1942; and 16.4 grams and 29 percent in 1943. It is apparent that the Macedonia black walnut has not exhibited those exceptional characteristics of thinness of shell and high kernel percent which were found in the original sample tested. Report from Minnesota--Letter from Carl Weschcke to Miss Mildred Jones The winter of 1942-43 was the most damaging on fruit and nut trees within my experience of 25 years in River Falls, Wisconsin. The main reason was that we had a long wet fall and all vegetation was in a succulent green condition when our first snow storm of September 25th hit us. For other details of this winter and the Armistice Day storm of 1941, the second in its deleterious effect on horticultural varieties, please write Mr. C. G. Stratton, Coop. Observer, of River Falls, Wisconsin, who is in charge of the U. S. Government weather bureau there. Mr. Stratton furnished me with an affidavit showing one of our very coldest winters in which the temperature went down, in February, to 47 deg. below zero. This was in 1936. This winter of extreme cold did very little damage to trees, and an apricot on which I had taken out a plant patent, subsequently called the Harriet apricot, went through this winter without any damage and bore fruit the next year. This gave me such confidence in its hardiness that I began to propagate it for sale. The winter of 1942-43 wiped out practically all of the apricot trees of this variety and all of the early Richmond cherries that had been growing on my farm for nearly twenty years. It killed more than half of the catalpa trees which were nearly as old. It also killed outright a large Stabler black walnut which had been grafted on a Minnesota seedling nearly twenty years previous. This was a fine large flourishing tree that bore each year and I had thought because of this behavior that Stabler was to be considered one of the hardiest of the black walnuts. It had stood up better than Thomas many winters. I could go on enumerating failures of many other varieties and species but it is a long story and a sad one. To make this report more concise I will now give you my opinion as to what is hardy under these severe tests.
