The Land of To-morrow. By Major J. 

 Orton Kerbev; 12mo. ; 400 pp.; illustrat- 

 ed. W. F. Brainard, New York, 1906. 

 "The Land of To-morrow" is a descrip- 

 tive narrative by a newspaper man and ex- 

 consul, giving interesting experiences and 

 observations during a journey to the head- 

 waters of the Amazon and over the Andes 

 through the unknown La Tierra de Manana. 

 the California of South America. The book 

 contains the history of a research for rub- 

 ber, instituted while Col. Kerbey was con- 

 sul to Para. Aside from its value as the 

 only practical summary of the rubber in- 

 dustry, there is the added charm of adven- 

 ture in a little known and practically unde- 

 veloped country, whose natural resources, 

 in the lines of forests and mineral wealth, 

 is vast. The many illustrations are excel- 

 lent. 



The Philippine Journal of Science. Pub- 

 lished by the Bureau of Science of the 

 Government of the Philippine Islands. 

 Vol. I., Nos. 1 and 2, June and July, 1906. 

 Manila, 1906. 



The June and July numbers of theJournal 

 contain a number of articles on various sci- 

 entific subjects. Readers of- Forestry and 

 Irrigation will .however, be particularly 

 interested in Mr. H. N. Whitford's contri- 

 bution, on "The Vegetation of the Lamap 

 Forest Reserve," appearing in both issues of 

 the publication. The article contains some 

 interesting tables of the various tree-species 

 in sample plots, with both general and spe- 

 cific observations regarding tree growth and 

 variety. Some interesting pictures of island 

 forests are included. 



Irrigation in Montana. Bulletin No. 72. 

 < mice of Experiment Stations, U. S. De- 

 partment of Agriculture. By Samuel 

 Forier, assisted by A. P. Stover and J. S. 

 Baker. Washington, Government Print- 

 ing Office, 1906. 



In their study of conditions in Montana. 

 Prof. Fortier and his assistants paid special 

 attention to the means of bringing about 

 nore economical use of the water sup- 

 ply now abundant in order to make pos- 

 sible the largest development of the State's 

 agriculture, and correct present sources of 



waste. After discussion of the various 

 phases of the situation, the bulletin makes 

 certain recommendations which, it is hoped, 

 will help the people of Montana in securing 

 protective and corrective legislation. Prof. 

 Fortier describes some improvements in 

 ditch-construction, and in irrigation practice 

 that should be valuable hints to the irri- 

 gator. 



Forest Planting on Coal Lands in West- 

 tern Pennsylvania. Circular No. 41, U. 

 S. Forest Cervice. By S. N. Spring; 16 

 pp. Government Printing Office, Wash- 

 ington. 



The occasion for forest planting in this 

 locality the most important bituminous 

 coal region of the United States rests pri- 

 marily upon the growing need of pit props, 

 and is intimately related to the whole in- 

 dustrial development of southwestern Penn- 

 sylvania. Intensive agriculture, forced by 

 an increasing population has led, in many 

 cases, to exhaustion of the soil, through 

 poor methods and other causes, and when 

 the coal minin industry shifts elsewhere, 

 as it is certain to do in the future, the best 

 crop such land can produce is timber. The 

 present volume is rich in suggestions for 

 planting in this locality, from the observa- 

 tions of the Forest Service in preparing a 

 planting plan in this section for the H. C. 

 Frick Coke Co. 



Sugar Pine and Western Yellow Pine 

 in California. Bulletin No. 69, U. S. 

 Forest Service. 42 pp. ; illustrated. Gov- 

 ernment Printing Office, 1906. 



The object of the study here presented 

 is to devise modifications in present lum- 

 bering methods which may lead to a more 

 conservative treatment of the yellow and 

 sugar pine forests of California. The lat- 

 ter has been one of the most valuable timber 

 trees of the state, and, with yellow pine, 

 with which it is intimately associated, both 

 in the forest and the market, has been 

 brought into greater prominence through 

 the exhaustion of eastern pine forests. The 

 bulletin makes it plain that conservative' 

 management is both necessary and practica- 

 ble if the tree is destined to be extensively 

 used.
