REPORT OF THE STATE ENTOMOLOGIST 10,11 89 



These maples were young trees which presented every appear- 

 ance of having recently been in as thriving and vigorous a condi- 

 tion as nearby unharmed maples, which latter were not marked 

 as having been sprayed, and no record was submitted to show 

 that they had been so treated. These trees, both the injured 

 and the nearby unharmed ones, were young and fairly well 

 separated. There was no evidence of overcrowding, though this 

 would doubtless occur later if all the trees grew and were 

 allowed to remain. 



At Park and Oakley avenues there were nineteen hard maples 

 perhaps more seriously affected out of about twenty-six sprayed 

 and presumably treated in the same manner as those discussed 

 above. These trees were smaller than those in the preceding lot, 

 and some at least of the injured maples even had the tips of 

 their branches well separated from those adjacent. They pre- 

 sented every indication of having recently been in a thriving 

 condition and there could have been no crowding for several 

 years at least. At North Fulton and Clinton avenues most of 

 the hard maples were killed on one block. These trees were 

 larger than those discussed above. Even here one could hardly 

 consider the maples crowded, though in a year or two such a 

 condition would probably develop. One of these trees was cut 

 down and the larger limbs, the trunk and the base of the roots 

 carefully examined for insect and other injuries. 



On Beechwood avenue in another part of the city we examined 

 several small hard maples marked as having been sprayed. This 

 work, we were informed, was done later and the injury was not 

 so severe, though three out of some seven or eight hard maples 

 were affected to some extent. 



Several other trees in this general section of the city were 

 examined. One was dying but the trouble appeared very dif- 

 ferent from the injury under discussion. The entire top was 

 dead and there was a vigorous growth of shoots at the base of 

 the larger limbs. This type of injury we have seen here and 

 there in the vicinity of New York City. Another affected tree 

 was observed. The foliage presented a generally unhealthy 

 condition. The trouble appeared to be similar to, or possibly 

 identical with, the bacterial affection which was so prevalent on 

 hard maples in the Hudson valley two years ago. The condition 

 of this tree is very different, in our estimation, from the severe
