MR. BIXBY: I have noticed at my place that cabbages planted under black walnut trees were somewhat stunted. I believe that it was the effect of the walnut trees growing so speedily that there was not enough nourishment for both.
THE PRESIDENT: The next lantern slide lecture will be by Mr. Reed.
MR. REED: (This lecture was delivered in a darkened hall where it was not possible for the reporter to take notes. However, the gist of the talk is here given).
The slides illustrated various methods of nut tree propagation, and that it is possible successfully to graft or bud nut trees at almost any time from February until the very end of the growing period. In working over large trees the first method in the season to be employed was shown to be that of the cleft graft. Following this, with large stocks, would be the slip-bark graft, or with smaller stocks, the chip-bud. The slip-bark graft has the advantage of being feasible at any time when the bark slips. Dormant scions are more often used with this form of propagation, although by no means necessary, as Dr. Morris has demonstrated that by applying a coat of paraffin over the entire scion and the cut surfaces of the stock, it is possible to use growing scions at almost any time when they can be obtained. The chip-bud is most successful during a relatively short period, beginning about ten days before the buds begin to swell and continuing until after the trees are practically in full leaf. From this time on the patch, or some other modification of the annular bud, is most commonly used.
In top-working, when the cleft-graft has failed, the patch-bud may be used late in summer, by inserting buds of the current season's growth in the base of the new shoots springing up from below where the cut was made in the stock for the graft, thus affording two opportunities for propagation during the same season.
The slides showed various methods of propagating the filbert by layering, and of propagating more difficult species by inarching. They were from a collection soon to be placed in the hands of the extension Service of the U. S. Department of Agriculture and of the various state colleges of agriculture.
THE PRESIDENT: We will now adjourn, and will meet in the room upstairs in this building at 10 o'clock tomorrow morning.
