Pulp and Cellulose in Norway (For- 

 eign Office, Annual Series, No. 2873, 

 G. Britain). British paper mainifact- 

 urers are the chief consumers of me- 

 chanical wood pulp. Production in the 

 autumn was restricted by the want of 

 water,, but the year 1901 was a better 

 one than 1899. 



The total value exported in 1901 

 was ^762,159, as against ^730,247 in 

 1900. There were two mills capa- 

 ble of producing jointly 17,000 tons 

 during the year. Of the total quantity 

 of 421,006 tons of pulp and cellulose 

 exported in 1900 the United Kingdom 

 took 275,201 tons. The production was 

 about the same as in 1900 ; in some 

 cases less, but prices were lower. Cel- 

 lulose was subject to the .same influences 

 as pulp. Less of this article was ex- 



ported than in 1900, and the value was 

 also less in proportion. The principal 

 demand was for the better qualities, 

 the lower descriptions bringing very 

 low prices. F'or 1901 the total esti- 

 mated quantity and value exported 

 was 93,789 tons and ^656,846, as 

 against 102,680 tons and ^762,077 in 

 1900. As in the case of pulp, the 

 United Kingdom took the bulk of the 

 exportation.

RECENT PUBLICATIONS. 



A First Book of Forestry. By Filibert Roth, 

 Chief of the Division of Forest Reserves, 

 U. S. Department of the Interior. Pp. 291. 

 Illu.strated. Ginn & Co., Boston. 



The scope of "First Book of Forestry" is 

 clearly outlined in the preface where the au- 

 thor states that "a desire has been expressed 

 to introduce this useful and interesting study 

 into our public schools and country homes, 

 and this volume is an attempt to provide a 

 book on the subject which shall .satisfy this 

 demand. In keepinj^ with this purpose there 

 has been no attempt to write a text-book or 

 manual of forestry ; but an effort has been 

 made to present in simple non-technical Ian 

 guage some of the general principles unt 

 h'ing the science and to state the metJrff)d; 

 which are employed and the objects t 

 tained in the practice of forestry." 



Professor Roth, with his wide experienaras 

 a student of and an instructor in forestj^ and 

 as a practical forester, is admirablv^j^ted to 

 write a book on the above lines. The " First 

 Book of Forestry'" will be widely circulated, 

 as it well deserves to be. It is written from 

 the proper point of view, and in precisely the 

 style to spread a knowledge of first principles 

 of forestry. 



The volume is divided into three partfe. 

 Part I contains a careful description of tHe 

 physical make-up of a forest. In Part II toe 

 general principles of forestry are outlined, ai|d 

 in Part III related topics are discussed. Thed-e 

 is also an Appendix, which contains the Doyle 

 Scribner log scale and a list of the more^ 

 portant woods and trees of the United States 

 The book is attractiveh- printed, and the large 



number of excellent illustrations add much to 

 its value. 



How to TcII the Trees. First series : The Cone 

 Bearers. By J. G. LEMmon, with hints

 tographs. Pp.66. Price, 50 cents. Pub- 

 lished by the authors. Oakland, Cal. 



This little booklet, with its carefully pre- 

 pared illustrations, is an excellent guide to the 

 easy identification of conifers, and will be j^ar- 

 ticjjlarl^nteresting and instructive to Califor- 

 tans^iP. long introductory article is devoted"^ 

 toJiJp^uestion of the forest endowment of the 

 ic slope. 



''orestry Quarterly. Published by the New 

 York State College of Forestry at Cornell 

 University, Ithaca, N. Y. , under the direc- 

 tion of a board of advisers consisting of 

 Dr. B. E. Fernow, Dr. John Gifford, and 

 Walter Mulford. Pp. 40. Single copies, 

 25 cents. Yearly subscription, |i.oo. 



The initial number of this publication has 

 just appeared, and it will be issued, as its title 

 indicates, four times a year. Its purpose, as 

 stated in an editorial announcement, is to de- 

 vote its pages to the professional or technical 

 interests of forestry, and to that end solicits the 

 interest and support of all workers in the field 

 of forestry. By reviews and resumes it will 

 aim to keep the profession in touch with cur- 

 rent technical literature. The first issue is a 

 very creditable one, and is not so extremely 

 ^ technical as to be without interest to the laj^ 

 reader.
