 different elevations change percepti-

Idyllwild is especially adapted to the 

 location of a school of forestry, be- 

 cause of the enormous surrounding 

 area of forested country. The Idyll- 

 wild Mountain Resort Company owns 

 5,250 acres, the edges of which link 

 with the borders of the Government 



Reservation which comprises 700,000 

 acres. Beginning at the gate of the 

 mountain, 500 feet elevation, where 

 the stage road begins to wind into the 

 wilderness toward Idyllwild and San 

 Jacinto Peak, the latter fifty miles dis- 

 tant by road and trail, there extends 

 one continuous procession of trees and 

 flowers of many species an unlimited 

 Nature library of living books and 

 texts. 



RECENT PUBLICATIONS 



The Structure and Development of 

 Mosses and Ferns, by Douglas Hough- 

 ton Campbell. The Macmillan Company ; 

 657 pp.; $4.50. 



In this second edition of his standard 

 text-book Prof. Campbell has made avail- 

 able a vast amount of newly-acquired 

 knowledge concerning a group of plants 

 (Archegoniatae) which has engaged the at- 

 tention of many botanists during recent 

 years. The work describes the peculiar 

 organs of typicae genera and is furnished 

 with no less than 322 figures to illustrate 

 the text. These are apparently carefully 

 drawn and are well reproduced. A very 

 full, thoroughly up-to-date bibliography and 

 a good index make the book satisfactory 

 and usable in every way.

 individual case. 



A Treatise on Pruning Forest and Or- 

 namental Trees, by A. Des Cars. Trans- 

 lated from the Seventh French Edition, 

 and with introduction by Charles S. Sar- 

 gent. Published by the Mass. Society 

 for the Promotion of Agriculture. 

 Notwithstanding the fact that this book 

 is forty years old, and its English transla- 

 tion upwards of twenty, it still remains the 

 standard text-book on tree pruning. Prof. 

 Sargent may be wrong when he states in 

 the introduction that tree pruning is prac- 

 ticed extensively in the commercial forests 

 of Europe, but he is quite right in saying 

 that lumber trees can rarely be pruned in 

 this country on account of the attendant 

 expense. It is, nevertheless, quite true that 

 trees of all kinds may be much improved 

 by pruning whether they are intended to 

 furnish lumber or to be purely decora- 

 tive. 



The principles laid clown in this little 

 manual have found universal acceptance, 

 and the book may serve as a guide for 

 all who have to do with the care of trees. 



The relation between the cost of pruning 

 and the increased value consequent upon 

 its operation will always be the point upon 

 which the utility of pruning operations will 



The Trees of Northeastern America, 

 The Shrubs of Northeastern America, 



by Chas. S. Newhall. Published by G. 



P. Putnam's Sons, New York. 



The popularity of these two manuals is 

 evidenced by the fact that the Trees of 

 Northeastern America has been printed 

 twelve times, and the Shrubs of North- 

 eastern America, four times. The books 

 are still among the most convenient that 

 we have for the identification of our east- 

 ern trees and shrubs, though in some re- 

 spects their peculiar value has been eclipsed 

 by later publications. The full-sized illus- 

 trations of the leaves and often of the 

 flowers and fruit make identification of the 

 species quite easy; while the keys that are 

 supplied furnish additional means to the 

 same end. The size of the books a narrow 

 octavo is inconvenient, and does much to 

 limit their usefulness. However, one who 

 is interested in the study of our native silva 

 and shrubby flora can scarcely get along 

 without them. 



First Report of the Board of Commis- 

 sioners of Agriculture and Forestry of 

 the Territory of Hawaii. Period from 

 July i, 1903, to December 31, 1004. Pp. 

 170. Honolulu, 1905. 



Considerable interest has been displayed 

 in forestry in Hawaii since the visit of Mr. 

 Wm. L. Hall, of the Bureau of Forestry, in 

 1903, and the appointment of Mr. Ralph S. 

 Hosmer as Superintendent of Forestry in 

 Hawaii in January, 1904. Two government 

 forest reserves have been established since 

 that time, and much information i-olkvu-d 

 by detailed study of the forests of Hawaii 

 practically a new field for the forester. Of 

 primary interest to our readers is Mr. Hos- 

 IIKT'S report and the reports of his as- 

 sistants, but there is also much interesting 

 information in the book concerning agri- 

 culture in the "Paradise of the Pacific."
