About ten years ago I noticed that there was no pollen coming from this tree and yet from the very beginning, even when there was no other pollen available except the wild hickory pollen from the _Carya cordiformis_, the Weschcke hickory produced nuts. Thinking that it was due to parthenogenesis I bagged clusters of pistillate blossoms, and although setting nuts they all dropped off which is typical of non-pollenization. I then bagged groups of pistillate blossoms which I pollinized with different available pollens of the _Carya ovata_ and these set nuts which started to grow, upon which I removed the bags. From this experiment I found that the Bridgewater did a very good job of pollenization and it became the tree that I considered as a compatible mate. Other trees that pollinate well are Kirkland, Deveaux and Glover; Beaver is not a good pollenizer and I have not experimented with Fairbanks to know whether it is satisfactory. The catkins grow vigorously on the Weschcke up to the time that the pollen sacs seem ready to open, then the catkin drops off. No pollen has ever matured that I know of. When dried from this state, they yield no pollen. I told Dr. J. W. McKay about this nearly seven years ago, and he asked for fresh samples of the catkins at different periods which I mailed to him in receptacles that he furnished. He wrote me a very nice treatise on this subject for inclusion in my book which I expected to be published at that time. The book was never published, however, since Orange Judd turned it down during the war for lack of paper as the excuse. I did not try any further to get it published, and since that time many new things should be added to the hazel hybrid chapter. Dr. McKay said that he is familiar with this action on the part of nut trees. I have felt that it was phenomenal since I have had no other such experience among all the nut trees with which I have experimented. However, this loss of pollen saves vitality apparently for the production of several times the pistillate bloom that I have seen on any other hickory with which I have worked and this apparently accounts for the prolificacy of the Weschcke when grafted on the native Wisconsin hickory.
