industry. On the shores and islands of Birch lake the best 

 timber occurs; that on the branches of the Severn river is gen- 

 erally small. 



At Fort Hope fairly clear nine-inch lumber was being sawn 

 from trees cut near the shores of Eabamet lake. One tree was 

 felled that gave a log over two feet thick at the butt and 100 

 feet long. The greater part of the forest is about eighty years 

 old, though in places trees reaching 140 years were found. These 

 old trees were on low-lying areas, that had escaped where the 

 higher and dryer parts were burned, and were not generally 

 large. Their growth-rings shovv-ed a rapid increase in size for 

 the first fifteen years and afterwards an extremely slow growth. 

 The large sandy tracts are now, for the most part, covered with 

 an open growth of banksian pine, a tree of small com.mercial 

 value. When the day comes in Canada for reforesting, these 

 districts might be replanted with pines commercially valuable. 

 Over large areas the spruces would, apparently, if more acces- 

 sible, be available for wood pulp. 



It was thought that the larch saw-fly, which destro3'-ed 

 so much of the tamarack of our northern forests, had ceased its 

 depredations, but Mr. Mclnnes found it still active in this dis- 

 trict. He states that the depredations of the larch saw-fly upon 

 the tamaracks along the Winisk river were noted in the previous 

 year's report. Since that time the ground covered b}' this in- 

 sect has been extensive, and some idea of the damage it has 

 done may be given. Last season all trees along the Winisk 

 river, from a point near the mouth to a point within a few miles 

 of the Weibikwei lake, were stripped; south of that area they 

 were untouched. . During the present spring and early summer 

 their ravages extended southward to the Albany river and west- 

 wards for sixty miles up the Winisk river and to about midway 

 between Eabamet lake and Lake St. Joseph, on the Albany.' an 

 area of about 14,000 square miles. 



Forest Conditions of Northern New Hampshire, by Alfred K,

This is the report of an investigation of the forests of North- 

 ern New Hampshire, made under instructions of the U. S. Bureau 

 of Forestry. The territory included in the investigation em- 

 braces a total of 1,951,977 acres or 2>2 per cent, of the entire 

 State. It contains the entire^'White Mountain region and is 

 drained by''four large river systems, the Connecticut, the Peni- 

 gewasset, the Saco and the Androscoesfin, all of which have 

 their origin within this region. The White Mountains occupy
