planting trees any deeper than they grew in the nursery. I prefer to plant them a little deeper, say two inches or so. I do not recall losing any trees seemingly from this slightly deeper planting, while I did lose a considerable number of seedlings last year that were inadvertently planted two inches or so too shallow. Outside of the hickory I have had little trouble in transplanting any trees excepting some of the hazels. Unless hazels, particularly American hazels, are very well rooted, they will need more care the first year than most nut trees, particularly protection from the hot sun and drought. If I get poorly rooted hazels I now plant them in a shady place for a year or two if they have not grown well the first year, and then move them where they are to stay. THE PRESIDENT: Mr. Snyder of Center Point advocates planting trees two to four inches deeper. DR. MORRIS: In Dr. Brooks' paper he spoke of some of the twig girdlers in the beetle stage which feed upon the bark of twigs before ovipositing, and he said that gives a weak point where we may attack them. On my place at Stamford, where there are forests, that would be impossible. I have had a good many hazels partially destroyed this year by girdlers. A great many of the branches have the larvae in them. I find also a large number of small hazels on which the leaves and branches are dying, though there is no apparent injury to the bark. Suddenly, however, a little twig will drop off and yet, in cutting into them, I did not find any larvae. DR. BROOKS: That happens to be the work of an insect which I am just beginning to study, one of the flat-headed borers, and the reason you have not seen the larva is that it is very small. It is not half an inch long. In the second year it comes out as an adult. I judge that control measures should be used in the spring, when I think without doubt that it would feed on the poisoned spray. DR. MORRIS: I find a great many larvae in dead twigs on the ground. If we are going to get this pest out of the way, we should not only look at the twigs on the tree, but at those on the ground as well. DR. BROOKS: That is true of all of these curculios. Dr. Morris' statement is true. The ground should be gone over and the dead and dying branches and twigs of the trees should be collected. The insects mature in them. DR. COLLINS: Would you advocate pruning often? DR. BROOKS: No. Adjournment to lecture hall. Mr. Henry Hick
