FORESTER' S REPORT. 89 



State. The disease is limited to pine trees with five needles, and 

 thus far has been discovered only on stock grown in German 

 or French nurseries. Home-grown planting material may there- 

 fore be depended upon. Nothing need be feared from this dis- 

 ease on any pine bearing two or three needles in a sheath. 



HICKORY BARK BEETLE. 



Only a few instances of serious damage by this insect have 

 been reported of late. It will undoubtedly be found here and 

 there where hickory trees have been weakened by fire, changes 

 in grade, sudden exposures, etc. If a tree is badly infested, that 

 is, if the borers are actively at work in the body, it should be 

 cut down and the wood burned. If the attack is in the twigs 

 alone, and the tree is valuable, the insects may be killed in their 

 burrows by being followed up with wires or destroyed by cutting 

 off and burning the twigs. It is not likely that the beetle; will 

 do much harta except where the trees have been previously 

 weakened. 



OTHER INSECTS. 



In consequence of the long dry summer many insects, such as 

 the maple louse, the tussock moth and the locust leaf miner, 

 which ordinarily do not appear in great numbers, have become 

 apparent. None of these is apt to do serious or permanent harm, 

 yet where the infestation is noticeable practicable remedies may 

 be applied. These will be recommended in each case upon request. 



In various parts of the State the so-called seventeen-year locust 

 has done some damage. As a rule, however, the loss of a few 

 twigs through the scarifying of the bark by the female in ovi- 

 positing does no particular harm. No serious permanent injury 

 has been observed. 



A WARNING. 



Ignorant or unscrupulous men who advertise themselves as 

 tree doctors, or who are interested in getting material for saw-
