I gave several of the original seedlings to friends who planted them in their gardens, where rich soil has stimulated them to grow at twice the rate of those on my farm. There were four individual pecan trees growing in or near St. Paul from my first planting, the largest being about 25 feet high with a caliber of five inches a foot above ground. Although this tree did not bear nuts I have used it as a source of scionwood for several years. These graftings, made on bitternut hickory stock, have been so successful that I am continuing their propagation at my nursery, having named this variety the Hope pecan, for Joseph N. Hope, the man who owns the parent tree and who takes such an interest in it.

By the year 1950 the tree had such a straggly appearance, although still healthy and growing but being too shaded by large trees on the boulevard, that Mr. Hope caused it to be cut down. The variety is still growing at my farm, grafted on bitternut stocks and although blossoming it has never produced a nut up to this time.
Another tree given to Joseph Posch of the city of St. Paul, Minnesota, had made even better growth and was luxuriantly healthy and in bloom when it was cut down by the owner because the branches overhung the fence line into a neighbor's yard. This was done in about 1950.
Another tree given to Mrs. Wm. Eldridge of St. Paul still flourishes and is quite large (in 1952 at breast height, 6 inches in diameter) but being in a dense shade, it has not borne any nuts.
The fourth tree, given to John E. Straus, the famous skate maker, presumably exists at his lake residence north of St. Paul. I have not seen it in the last seven or eight years.
Although they are not as hardy as bitternut stocks, I have found the wild Iowa pecan seedlings satisfactory for grafting after five years' growth. I use them as an understock for grafting the Posey, Indiana and Major varieties of northern pecan and find them preferable to northern bitternut stocks with which the pecans are not compatible for long, as a rule, such a union resulting in a stunted tree which is easily winter-killed. Although the Posey continued to live for several years our severe winters finally put an end to all these fine pecans. The root system of the seedling understock continued to live, however.
I chanced to discover an interesting thing in the fall of 1941 which suggests something new in pecan propagation. There were two small pecans growing in the same rows as the large ones planted fifteen years previously. When I noticed them, I thought they were some of this same planting and that they had been injured or frozen back to such an extent that they were mere sprouts again, for this has happened. I decided to move them and asked one of the men on the farm to dig them up. When he had dug the first, I was surprised to find that this was a sprout from the main tap root of a large pecan tree which had been taken out and transplanted. The same was true of the second one, except that in this case we found three tap roots, the two outside ones both having shoots which were showing above the ground. Another remarkable circumstance about this was that these tap roots had been cut off twenty inches below the surface of the ground and the sprouts had to come all that distance to start new trees. All of this suggests the possibility of pecan propagation by root cuttings. These two pecans, at least, show a natural tendency to do this and I have marked them for further experimentation along such lines.
On the advice of the late Harry Weber of Cincinnati, Ohio, an eminent nut culturist, who, after visiting my nursery in 1938, became very anxious to try out some of the Indiana varieties of pecans in our northern climate, I wrote to J. Ford Wilkinson, a noted propagator of nut trees at Rockport, Indiana, suggesting that he make some experimental graftings at my farm. Both Mr. Wilkinson and Mr. Weber gathered scionwood from all the black walnut, pecan, hiccan and hickory trees at their disposal, for this trial. There was enough of it to keep three of us busy for a week grafting it on large trees. Our equipment was carried on a two-wheeled trailer attached to a Diesel-powered tractor, and we were saved the trouble of having to carry personally, scions, packing material, wax pots, knives, pruning shears, tying material, canvas and ladders into the woods. Mr. Wilkinson remarked, on starting out, that in the interests of experimental grafting, he had travelled on foot, on horseback, by mule team and in rowboats, but that this was his first experience with a tractor.
