424 JOURXAL OF FORESTRY 



Perhaps, however, the Forest Service is going to an extreme when it 

 makes the maximum charge for residence permits at $25 per annum. 

 It appears to the reviewer that this maximum should probably be in- 

 creased to $50 or $100, but this is a minor point compared with the 

 great success of the use of the forests for recreation. 



The increased road and trail improvement during the year is gratify- 

 ing. But when it is realized that the Federal co-operation with the 

 States in fire protection was only to the extent of $93,000, it is clear 

 that Congress should provide additional funds for the coming year. 

 The great financial achievement of the Forest Service seems to be in 

 having spent $2,000,000 at the Madison Laboratories, thereby saving 

 industry at least $30,000,000 annually. It is a pity that Congress is 

 not more liberal in its appropriations for forest research since investi- 

 gations had to be reduced 3G per cent below the preceding year owing 

 to restricted appropriations. // cz'ery Congressman would read this 

 report, it is certain that he zvoitld be eonvinced that money appropriated 

 for the Forest Service is money ivell invested. But he would probably 

 ask, "When will the National Forests be self-supporting?"

Yelloiv Birch ajid Its Relation to the Adirondack Forest. By E. F. 

 McCarthy and H. C. Belyea. Tech. Pub. No. 12, N. Y. State College 

 of Forestry. 50 pp.. 8 figs. 1920. 



This is a very timely contribution to our knowledge of Adirondack 

 hardwoods. Like faith, hope, and charity in the Scriptures, there re- 

 main beech, birch, and maple in our North Woods — -"but the greatest of 

 these is" birch. 



The introduction explains that a complete study of the yellow l^rch 

 was planned by the college and that the work was started by several 

 departments. The publication under review is a part of this larger 

 study and, after a fundamental discussion of the types and conditions 

 found in the Adirondacks, presents comparative data to show the 

 silvicultural relation of the birch to the other native species. 



The types recognized and described are those almost universally 

 agreed upon for the Adirondack region : Swamp, spruce flat, hardwood, 

 and upper spruce slope. Swamp is "of small importance in a study 

 of yellow birch . . . since birch does not enter into the forest 

 as a merchantable tree in the true type." Tables showing the virgin
