L^ieberg ; and Forest Conditions in the Olympic Forest Reserve, 

 Washington, by Arthur Dodwell and Theodore F. Rixon. 



These reports, like former ones of the Survey, are mainly in 

 the nature of a census ; the works appear to have been done with 

 care and intelligence, and manj' excellent regional descriptions 

 and silvicultural notes are to be found scattered through them. 

 The usual excellent photographs and maps are included and add 

 greatly to the value of these papers. 



Sylviculture par A. Fron, ingenieur agronome, inspecteur ad- 

 joint des eaux et forets, professeur a I'ecole forestiere de 

 Barres (Encyclopedic Agricole) Paris 1903. Pp. 563 16°, 

 PI. 55. 6 frcs. 



This latest volume is of interest because it is written for the 

 farmer rather than the professional forester, explaining in simple 

 language yet with professional background the principles and 

 practices of silviculture. It includes also chapters on forest 

 measurement and forest economy.
