sons before tran.s])lanting. Unfortunately this will add to the cost of 

 grafted hickories which even now are so expensive to produce that 

 almost no nurserymen grow them. 



Anotlier one of the commonly accepted princii)lcs that I do not 

 now follow is that of not planting trees any deeper than they grew in 

 the nursery. I prefer to plant them a little deeper, say two inches 

 or so. f 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' pajjer 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 maj'- attack 

 them. On my place at Stamford, where there are forests, that would 

 he 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 1 -ranches are dying, though there is no apparent injury to the 

 bark. Suddenly, however, a little twig will drop off and yet. in cut- 

 ting 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 oni the tree, but at those on the ground as 

 "well. 



Dr. Brooks: That is true of all of these curculios. Dr. Morris'
