Two RECENT BOOKS on forestry = will help greatly to popularize the 

 knowledge of this subject, and too much cannot be said concerning their 

 usefulness. The science of forestry has made such rapid progress during 

 the last ten years that any work that discusses in a readable yet scientific 

 way the subject in all its phases should find a ready sale among teachers of 

 nature-study, woodland owners, beginners in forestry, and others. Both 

 works have features in common, yet in a way they supplement each other. 



Roth presents the subject in the simplest possible manner. The rela- 

 tion of the forests to light, shade, soil, moisture, and temperature is dis- 

 cussed. The subject of "forestry" is treated under the following headings: 

 the raising and keeping up the forest, its care, its use, and its business. A 

 third part deals with the forest as a protective cover, the distribution of the 

 forests in the United States, the wood and its properties, and closes with a 

 valuable key to the common trees of the United States. 



GiFFORD in the first part discusses the meaning of "forest'* and "forestry/' ) 



and treats of wood lots on farms, the forest canopy, the forest as a soil 

 improver, the geographical distribution of forests, and barriers to forest 

 extension. Part II treats of the formation and tending of forests. The 

 author recognizes the intimate relations existing between the study of forestry 

 and forest botany, especially plant ecology. In the third part the industrial 

 phase of the subject is treated in a very interesting way, and in Part IV are 

 brief descriptions of the location, areas, and special features of the forest !

 tions of photographs. — H. N. Whitford. 



Books for schools of pharmacy. 



Dr. Albert Schneider's recent book^ dealing with powdered vegetable 

 drugs is the only work of its kind in English. In it 195 vegetable powders 

 are described, 164. of them being figured. The first part treats of the color, 

 odor, and test of vegetable drugs, the general histology of vegetable powders, 

 equipment and methods of examination, parasites, adulteration, powdering 

 and sifting, and includes two keys for identification. The second part con- 

 tains a special description, with illustrations of the more important vegetable 

 powders used in the United States. 



Dr. Henry Kraemer has prepared a book^ intended to meet the 

 botanical needs of students of pharmacy. The first part deals with plant
