FORESTER'S REPORT. 37 



cially warned not to spend money on so-called cures. No prac- 

 ticable remedy has been discovered. If one shall be found the 

 State authorities will make the fact known promptly. Recently 

 published statements that children have been poisoned by eat- 

 ing nuts from diseased trees are not substantiated, though in- 

 vestigations to determine the fact are under way. 



Assurance can be given that the disease attacks no other 

 species than chestnut, and that it has no in-jurious effect upon 

 the wood. A blight similar to that of the -chestnut has been 

 observed on chestnut oaks. Chestnut oak is not a chestnut but 

 an oak of the white oak group. The disease proves to be com- 

 paratively well known to plant pathologists and is not danger- 

 ous. Its occurrence, however, should be promptly reported so 

 that it may be kept under observation. A somewhat similar 

 disease has also been- found on norway maples. All reported 

 cases- are under observation. Serious trouble may come but 

 need not be anticipated. 



ELM LEAF BEETLE. 



The damage done by this pest was much less serious than it 

 has been for several years. Most communities continued their 

 sprayings, but in a few ,it was omitted with no serious results. 

 The indications are that the insect is coming under control and 

 that before long the expense. of spraying may be saved, but for 

 the present shade tree commissions, city authorities and private 

 owners are advised to hold themselves and .their spraying 

 equipment in readiness. If the pests shall have been so reduced 

 that there is no serious danger next spring the State Entomolo- 

 gist will advise that spraying is not necessary. In the absence 

 of such advice the usual precautions should be taken, since 

 proper spraying at the proper time is an infallible remedy. 

 Where trees are weakened in other ways, as they often are, 

 other measures are indicated. Specific ; advice will be given 

 upon request. 



HICKORY BARK BEETLE. 



This insect is doing more and more daftiage. In some sec- 

 tions most of the hickory trees are gone. Nevertheless, all fear
