The Rangeley region was visited early iu September and here 

 also the injury by the budworm seems to be on the decrease. 

 Conclusive evidence of its presence was found in the partly de- 

 foliated spruce and fir, showing the characteristic work of this 

 insect. In some cases the empty pupal skins still adhered to in- 

 jured twigs. Along the woodsland trail from York's Camp. 

 Loon Lake, to Richardson's Camp, Kennebago Lake, quite a 

 number of the balsams have been killed during the last several 

 years, but a large percentage even of the larger growth had es- 

 caped. But relatively few spruce trees were dead, although 

 many showed the effects of partial defoliation in the presence 

 of dead branches and leaders. The work of the caterpillar dur- 

 ing the past summer (1919) has resulted in only partial defolia- 

 tion and in practically all cases observed ; the trees will doubtless 

 recover. Apparently the present infestation has at no time been 

 disasterously heavy in this locality. 



The observations in Piscataquis County were made during the 

 latter part of July in company with Dr. C. T. Brues, of the 

 Department of Entomology of Bussey Institution, Harvard Uni- 

 versity and Mr. H. B. Shepard, Forester for the Eastern Manu- 

 facturing Company. The trip was made by automobile from 

 Lily Bay on Moosehead Lake, to the foot of Chesuncook Lake, 

 thence by boat, canoe and on foot through Chesuncook Lake, 

 Round Pond and Telos Lake. By this route observations were 

 made in some thirteen townships and included a variety of con- 

 ditions. Without doubt the greatest amount of damage en- 

 countered on this trip was to be observed in the forests at each 

 side of the road between Lily Bay and Ripogenus Dam in the 

 holdings of the Great Northern Paper Company. In certain 

 localities, often of considerable extent, practically every fir, red 

 spruce, and hemlock of any considerable size had been killed and 

 most of the younger trees down to a heighth of only a few feet, 

 were either killed or badly injured and distorted. The oc- 

 casional white spruces seemed to have escaped with no injury or 

 with only minor damages. Indeed, throughout the entire area 

 examined, the white spruce seemed to possess some degree of im- 

 munity from attack and injury although in the regions of Houl- 

 ton according to the observations of Mr. Win. C. Woods reported 

 by Dr. O. A. Johannsen in Bulletin No. 210 of the Maine Experi- 

 ment Station, the white spruce was second only to the balsam
