DR. STABLER: The President has mentioned the combination of apple and walnut trees. I would like to ask him if he has seen any deleterious effects upon the apple from the proximity of walnut roots. Now, some of my friends in Montgomery county have the idea that an apple tree will not live within fifty feet of a walnut tree. I have, myself, seen a number of apple trees die, apparently because they were neighbors of walnut trees. I wasn't sure that that was the cause of death, but they died, and walnut trees situated in an apple orchard will have a ring of dead apple trees around them. Now that is one case that I know of where the walnut tree acts injuriously upon the vegetation to which it is neighbor. All of the farm crops, wheat, corn, grass, and oats, and rye, etc., seem to thrive just as well under the limbs of a black walnut as they do away from it. In fact, frequently you see the grass greener and more luxuriant right up to the trunk of the tree than anywhere else, but it doesn't seem to be true of the apple. Now, I would like to hear from the President. THE PRESIDENT: I simply made that as a suggestion and referred to this instance as an illustration of the effect of fertilization on the walnut. DR. AUGUSTUS STABLER: Well, how are those apple trees doing? THE PRESIDENT: I had enough trouble without looking for more by mixing walnut and apple trees. The walnut trees are small, merely the growth from stubs repeatedly cut. The next on our program is a paper by Mr. McMurran, of the Department of Agriculture, upon the question of diseases of the English walnut. Mr. McMurran. MR. S. M. MCMURRAN: I am sorry that in this, my first appearance before this Association I haven't a more optimistic and encouraging subject to talk on than diseases. You men and women who are burdened with establishing this industry have enough on you without contending with diseases, and it was not my intention to talk upon diseases at this meeting, but Mr. Littlepage, Mr. C. A. Reed, and Mr. Jones, and several others, have been urging the matter strongly, which explains my appearance at this time. Walnut blight is a very common and serious disease on the Pacific Coast. It may be a native disease, though it has never been reported on native black walnuts, and it has proved a very serious menace to the seedling English walnut groves on the Pacific Coast.
