If any one wishes to contradict my statement about these trees living with such treatment, I will admit that I am not speaking from experience with regard to the pecan, but I believe the experience of others admirably verifies the statement I have made. I am, however, speaking literally from my own experience when I refer to the black walnut. For ten summers past I have in July and August scythed off a certain tract of stump land planted to apples. Each year black walnuts and butter nuts have been cut, and now at the end of that time the stubs are still annually throwing up vigorous shoots 2-1/2 to 4 feet in length, and if they are allowed to escape for a season, they dart past a man's head so fast he wonders what has happened. While I hope to experiment for forty more years on my mountain side in the attempt to cover it with waving fruitful trees that are so immune to pests as not to need spraying, I shall never again be caught with only one possibility upon a given piece of land. If I should top-work my native hickories to shagbark, which I know involves considerable waiting and considerable uncertainty, I can, with very little expense, put upon the same ground a full stand of grafted black walnuts and a full stand of budded pecans, or if I do not care to go to that much trouble, I can graft my hickories and plant my native black walnuts and merely keep them there in submerged condition as reserve trees ready to be grafted at any time. For a pecan orchard I can do exactly the same thing, using black walnuts as fillers, possible successors, or as ungrafted reserves. For the Persian walnut, the black walnut can again come in as a filler or as a reserve, and for grafted blacks of any variety, other blacks can be kept waiting for the arrival of possible better varieties which could easily become the head of the corner. My experience with transplanting seedling pecans shows that they, too, can, without serious difficulty, be planted out in such rough land and kept waiting there for years until the day of possible utilization.
