Report of the Chief of Division of Forestry U. S. Department of 
Agriculture, 1886.—B. E. Fernow, (loc. cit. pp. 149-226; 
diagrams; also reprinted). 
There is so much of scientific interest and practical sugges- 
tion in Mr. Fernow’s report that we cannot hope to do it justice 
in the space at our command. Among the most important sub- 
jects discussed are “‘ Forest Planting and Management in the 
United States;” it appears that there are as yet very few ex- 
tensive forest plantations, though there are numerous small ones, 
forming in the aggregate quite a considerable area, and affording 
encouragement for the creation of new forests ; however, “ this 
hopeful prospect does not exist in regard to the remaining 
natural forests.’ The prosecution of biological studies of our 
timber trees is earnestly urged and an outline of the main points 
of inquiry is given; there is also a preliminary list of our ninety 
most important timber trees, with their distribution, quality and 
ae ses. of wood and practical remarks on their planting. :
