The report of the results of the contest also contains other interesting data, 

 while the value of such a competition, as pointed out by Lamb, 24 consists not 

 only in promoting interest in the protection of tree individuals and in the con- 

 servation and preservation of forests, but also in affording data for the solution 

 of problems of distribution, of growth, and of duration. In this connection 

 he has prepared maps showing the distribution of 6 of the important species 

 represented and the location of the best specimens reported in the contest. 

 It is hoped that public interest in the subject will not cease with the conclusion 

 of the contest. — Geo. D. Fuller. 



American forestry. — Recent changes and improvements have made the 

 magazine known as American Forestry valuable not only to the forester but also 

 to the botanical teacher or student interested in trees. An excellent feature 

 is that of devoting special attention to one particular tree species in each issue. 

 Well written articles are given dealing with the identification, characteristics, 

 and habits of the trees, and also with the lumber and its uses. During the 

 first half of the current year the following species have been the subjects of 

 special consideration: Quercus alba, Pseudotsuga Douglasii, Thuja plicata, 

 Betula papyrifera, Ulmus americana, and Sequoia sempervirciis. The excellence 

 of the illustrations in these articles is worthy of note. 



There are also, in addition to the articles of more particular interest to the 

 professional forester, others upon more general but quite as timely topics. 

 Among these we may note as examples a finely illustrated article upon Cap- 

 ressus macrocarpa under the title of "The tree of legend and romance," in the 

 February issue; and several dealing with forests in time of war, showing some 

 of the devastating effects of the present European conflict. A recognition of 

 various phases of forest and country life is seen in regular departments devoted 

 to children, birds, ornamental and shade trees, and to wood preserving, while 

 quite as important are the very extensive lists of current literature. Finally, 

 as an indication of the international scope of its interests is a page of its notes 

 and news items devoted to Canadian forestry and foresters. — Geo. D. Fuller. 



A vegetational map of the United States. — Shreve 25 has compiled a map 

 of the range of the principal types of vegetation in the United States, basing 

 the boundaries of the various subdivisions upon purely vegetational criteria. 

 The primary classes of vegetation are the well recognized ones of desert, grass- 

 land, and forest. Of these the first and last have been subdivided, but the 

 data available for the grassland are not regarded as sufficient to afford a basis
