THE PRESIDENT: I have been enthusiastic over the chestnut for twenty years this season, and these are matters in which I am greatly interested. As I see it, the problem is one that is really much bigger than the chestnut. The whole field of nut growing, which is now on the edge of great accomplishments, is likely to be seriously injured, because the most conspicuous thing in nut growing is the taking advertisement of the firm whose bad trees have been referred to by Dr. Metcalf. I think we do not appreciate the seriousness of the situation. The firm Dr. Metcalf referred to is selling trees that are diseased in places where they are sure to die quickly. Other men are similarly selling trees, with less skillful advertising, perhaps, but probably no less diseased. Most of these nurserymen may be honest in their belief that they are putting out stock that is not diseased. But in the infant trees it is almost impossible to detect the blight, so that the tree goes out looking like a perfectly good one. It may be two or three seasons before it dies. Now, the economic aspects are these: Who should stand the loss, the man in the nursery or the man in the orchard? It is a toss-up, it seems to me at present, with the results apparently in favor of the nurseryman rather than in favor of the citizen. The people who have an interest in nut growing are going to have that interest lessened or destroyed by beginning with a bad kind of tree. There are possibilities of a great national injury, as I see it, if we let this thing go on. DR. KELLERMAN: Well, as a constructive policy for aiding in the establishment of nut culture, I think your policy is sound, but as a question of economics of operation, I doubt whether any plan of that sort can be established, beyond the plan of merely giving the general advice that such planting is attended with very grave risks. THE PRESIDENT: Have you not authority, or does not authority exist, to prohibit shipment? DR. KELLERMAN: The plant quarantine act gives the Department authority to quarantine infected areas and to place certain restrictions on shipments. To place any such restriction, however, it must be plainly established that beneficial results are going to result, not to a particular industry necessarily, but to the general public. The difficulty in establishing a quarantine on the shipment of nursery stock is the apparent impossibility of saying that that is going to stop the spread of the disease. That is one question. The other problem is the difficulty of determining what is infected territory and what is not. We have very serious difficulty in making regulations, excepting as between definitely infected territory and definitely clean territory. THE PRESIDENT: And you don't have the authority to make a sweeping, blanket prohibition of the shipment of a certain thing? DR. KELLERMAN: No, we haven't that authority.
