Only l l /i per cent, of last season's 400 fires 

 in National Forests of Utah, southern Idaho, 

 western Wyoming, and Nevada caused losses 

 in excess of $100. 



There were 400 fires this year on the National 

 Forests of Utah, southern Idaho, western 

 Wyoming, and Nevada, or 15 more than in 

 the most disastrous season of 1910. Yet the 

 cost of extinguishing them was only one-third 

 and the damage only one-thirtieth of that of 

 the earlier year. The difference is due to 

 better organization now, and to more roads, 

 trails, and telephones. 



Only one modern sawmill is operated in the 

 territory of Hawaii. 



In District 4 of the Forest Service, with 

 headquarters at Ogden, Utah, lightning caused 

 36 per cent, of this year's fires and campers 

 27 per cent. 



As showing the possibilities for tree growth 

 in regions where irrigation has to be depended 

 upon, it is pointed out that Boise, Idaho, has 

 as many as 94 different kinds of ornamental 

 and shade trees. 



The Laurentide Company of Quebec, pro- 

 ducers of pulp and pulpwood, is reforesting 

 its non-agricultural cut-over lands. It is also 

 importing reindeer from Newfoundland, to 

 see if they can take the place of dogs in winter 

 woods work. 



A small railroad operating an oil-burning 

 locomotive on the Tahoe national forest, 

 California, had a breakdown during the past 

 summer and burned wood instead of oil for one 

 day. On this day fifteen fires started along 

 the right of way. During the preceding year 

 only one fire occurred near the railroad and 

 it was not thought that the engine was respon- 

 sible for that one. 



Lodgepole pine, one of the principal trees of 

 the Rocky Mountains, makes good strong 

 wrapping paper and pulp board. 



Osage orange wood is a source of dye and 

 can be used to supplement the imported fustic 

 wood, as a permanent yellow for textiles. 



During the past two years forest officers 

 have killed nearly 9,000 predatory animals, 

 more than three-fourths of which were coyotes.

Forest Valuation, pp. 310. By Herman 

 Haupt Chapman, John Wiley & Sons, 

 Inc. New York. $2.00. 



With the development of forestry in this 

 country has come an increasing demand for 

 definite information concerning the value of 

 standing timber, mature and immature, of 

 forest soil, and of the forest as a whole. Pro- 

 fessor Chapman's book affords the means for 

 determining these important points and for 

 answering such perplexing questions as: Does 

 forestry pay? Is forest property a good 

 investment? How shall young timber be 

 valued? How shall damages to standing 

 timber be appraised? How are stumpage 

 values accurately determined? What is the 

 basis for deciding whether a given tract is 

 chiefly valuable for agriculture or for forest 

 production? 



The reader of this book will realize that 

 contrary to common belief these problems are 

 not in a class by themselves but are solved in 

 much the same manner that all values are 

 determined, for the principles of forest ralua- 

 tion are shown to be in strict accord with the 

 customs and principles of ordinary business 

 accounting. The chief distinction is that 

 forest valuation is concerned with much longer 

 periods of time than are most financial calcula- 

 tions. 



In order that the student or reader may 

 fully appreciate these relationships the first 

 four chapters of this book are devoted to a 

 resume in simple terms of the general principles 

 underlying economics. Especial emphasis is 



laid upon the theory and application of com- 

 pound interest as a mathematical meaiis of 

 determining value. 



To the layman as well as to the average 

 student the presence in a book of many seem- 

 ingly complex formulae is likely to give the 

 impression that the subject is too difficult for 

 them to master. If, however, the introductory 

 chapters of the present volume are carefully 

 read and the significance of the mathematical 

 symbols is once understood this difficulty 

 vanishes. The subject demands thought, to be 

 sure, but if the reader is ' reasonably pains- 

 taking in the beginning he will be surprised at 

 the readiness with which he is able to grasp 

 the subsequent details. 



This book is designed with special reference 

 to the needs of American conditions. Instead 

 of emphasizing, as most European treatises on 

 the subject do, the determination of the expecta- 

 tion value of forest soil, greater consideration 

 is given to matters of more practical import 

 here, such as stumpage values, sale values, and 

 appraisal of damages. No problems have been 

 included in the text, apparently on the as- 

 sumption that if the principles underlying 

 them are fully understood such problems can be 

 readily supplied and solved by the instructor 

 or reader. 



Teachers and students in forest schools and 

 others who are interested in this important 

 subject will welcome this book for it is the first 

 American treatise on forest valuation to cover 

 the field in a manner at once comprehensive 

 and simple. - S. J. R.
