At the Michigan State College where the temperature went to -18 degrees F. vigorous McDermid grafts on a thrifty black walnut were uninjured whereas all the Franquette grafts on the same tree were killed outright. Similar results were noted on several trees at the Kellogg Farm near Augusta, Michigan. Group 3. _Carpathian Walnuts._ This strain of Juglans regia was introduced into Canada by Rev. P. C. Crath of 48 Peterboro Avenue, Toronto, Ontario, from the Carpathian mountains in southeastern Poland. In this part of Europe the winter temperatures are reported to go to -20 degrees F., and occasionally lower. In the winter of 1928-29 a vast amount of injury was done to fruit trees and the less hardy English walnut trees in Poland, but a number of English walnuts came through without serious injury. Scion wood of some hardy selections was sent in 1932 to the writer by Mr. Crath, who was then in Poland. This material was grafted on vigorous growing black walnuts in the spring of 1932 and good results were secured with two varieties. These varieties made a vigorous growth, but notwithstanding this they showed not the slightest injury in the spring of 1934. The growth made during the summer of 1934 has been remarkable and if this unusually vigorous growth survives the coming winter it would seem as though we have an exceptionally hardy strain. The nut characters and productiveness of these varieties have not yet been determined in Michigan, but if they are equal to some of the trees of the same origin, then we will have very valuable trees. These strains have been named Crath and are distinguished by Nos. 2 and 5. About 100 small seedlings of Polish origin were purchased from Mr. Landega of Toronto, Ontario, an associate of Mr. Crath, and planted at the Kellogg Farm in 1932. These trees have been subjected to trying conditions through drouth, competition with alfalfa, late growth and severe winter temperatures. As a result some have died, but a number are growing nicely, and it is expected that some of these will eventually become established. Seedlings of this lot suffered only slight injury near Sparta, Michigan, but grafts from these same seedling trees set on a vigorous young black walnut were very severely injured. Another tree from this group endured the severe cold at Madison, Wisconsin, during the past winter and made a rapid growth this season.
