THE PRESIDENT: I think Dr. Stabler has stated a very well-known principle, not only of horticulture, but also of agriculture. Last year we questioned Mr. W. C. Reed as to the condition of a certain top-worked, heavily forced, black-walnut we had seen the year before at Vincennes. We were confirmed in our belief that the tree was dead, but that another tree budded at the same time with the same bud-wood and not forced, lived. We had a dry summer that year, a wet fall, twenty degrees below zero at Christmas, dead apple trees. I suspect that Mr. Littlepage has a problem in the balance of tillage and top-working. DR. STABLER: I think if he visits his neighbor, Professor Waite, he will find out how to manage trees so they won't winter-kill, because he knows how to fix it. (Laughter.) MR. LITTLEPAGE: I treated the trees just like the pecan. I have never seen it possible yet to over-stimulate a pecan and winter-kill it. I don't say it isn't possible, but I have never seen it. THE PRESIDENT: I can show you a few. MR. M. P. REED: Mr. President, we have that condition in the nursery row. MR. LITTLEPAGE: Well, those are grafted, are they not? MR. M. P. REED: Grafts and buds, both. DR. MORRIS: In regard to the grafting of the Persian walnut upon black walnut stock. In Connecticut, we have three species of mice--the common field mouse, the pine mouse, and the white-footed mouse. These mice all follow in the holes of the moles, and they are very fond of the bark of the Persian walnut, and will destroy a good many of them. Now, with the black walnut, on the other hand, when one of these mice comes along and takes a bite of that, he shuts one eye, cleans his teeth, and then goes on to something else. (Laughter.) Now, in our country the soil is practically all acid. The black walnut will grow in pretty acid soil. The Persian walnut almost demands a neutral or alkaline soil. So, for Connecticut there is no doubt that we really need the black walnut stock for the Persian walnut. THE PRESIDENT: Any further problems that are vexing the orchardist with regard to the Persian walnut? If not, I think this is a suitable time to bury it until next year. Col. Van Duzee, a man who has had more experience with the pecan than almost any one else in the room, has kindly consented to make his contribution at this time. Col. Van Duzee.
