No. 4.] REPORT OF STATE FORESTER. 239 



Pine Tree Blioiit. 



The alarm in regard to the disease called the pine tree blight, 

 which was so prevalent two years ago, has very mnch subsided 

 of late. Occasional trees have died from this cause during the 

 year, but nothing equal to the number of last year, which in turn 

 was less than that of the year before. Our people generally 

 have become familiar with it, and are following the practice of 

 cutting out and utilizing all pine trees of commercial size that 

 are badly aflfected. It is quite generally believed that we have 

 little to fear from this malady in the future in growing white 

 pine. 



The Chestnut Bark Disease. 



Tliis disease of the chestnut has been extremely disastrous 

 along the southern Hudson River district and in certain sections 

 of Connecticut. By reading about it and its results in the above- 

 named territory, many of the people owning chestnut forests 

 have become alarmed and written to our office. We have not as 

 yet had any large area reported which was thought to be infested 

 with this chestnut disease. Experts on the subject seem to differ 

 as to the cause of the depredation. The United States Depart- 

 ment of Agriculture claims the disease is Diaporthe parasi- 

 tica, and that it is contagious; while equally skilled botanists, 

 like Dr. G. P. Clinton of Connecticut and Dr. G. E. Stone of 

 Amherst, claim that it is due to unfavorable climatic condi- 

 tions. 



It is believed to l)e unnecessary for us to worry at present over 

 the chestnut bark disease in Massachusetts. If chestnut trees 

 here and there become unhealthy, it is a safe rule to remove 

 them, and thus minimize possible trouble. This method we are 

 ]iractising with the white pine blight. It is certainly to be 

 hoped that this trouble may not come our way, for our chestnut 

 growths are valuable properties. 



Forestry Exhibits. 



During the year various forestry exhibits, mainly showing 

 moth work and seedlings, have been made, the principal ones 

 being before the following organizations: the New Eugland
