No. 4.] REPORT OF STATE FORESTER. 503 



Furthermore, these operations stand as practical and easily 

 accessible object lessons in the practice of forestry, and are 

 awakening great interest in the subject among many of our 

 citizens. J\Ir. Kneeland and the young men assisting him in 

 this work are accomplishing a great amount of constructive 

 moth and forestry work that is bound to prove of great future 

 economic value. 



Forest Mapping. 



This last season the field work of the forest survey of Worces- 

 ter County towns has been completed save for a portion of 

 Hubbardston, which will have been finished shortly after this 

 report goes to the printer. 



A very thorough forest map of Winchendon, showing the 

 character of growth on every portion of the town, was made in 

 co-operation with the United States Bureau of Entomology. 

 Mr. Ingall, of the United States Bureau of Entomology, and 

 iNIr. C. H. Guise, surveyor for this office, did the field work of 

 forest mapping, being accompanied by. Mr. Wilcox and Mr. 

 Schaflfner, respectively, experts from the United States Ento- 

 mological Laboratory, who collected data for classifying and 

 mapping areas according to their susceptibility to gypsy moth 

 infestation. The field w^ork was done by running- the paced 

 compass lines from one town line to the other every quarter 

 mile, instead of every half mile as has been done in other towns. 

 This quarter-mile strip in the field enabled Mr. Ingall to com- 

 plete a very satisfactory detail working map showing in different 

 colors the difi'erent combination of species. It is hoped the 

 town will use this in eradicating the gypsy moth food, which 

 would prove at the same time a long step towards converting 

 the large w^oodland area of the town into a coniferous forest, 

 practically immune from the gypsy moth. It is to be hoped 

 that the town of Winchendon will co-operate with the Federal 

 and State governments in this, since it would not only prove 

 a valuable experiment on a large scale with gypsy moth 

 conditions, but would make the woodland areas of Winchendon 

 vastly more valuable than at present by converting large areas 

 of practically worthless growth into pine. For Winchendon 

 we have figures showing in detail the area in practically every 

 combination of species for different sizes of growth.
