THE AMERICAN BOTANIST. 



the information is secured reads on about others, attracted 

 by the text. Shrubs lend themselves so well to decorative 

 planting that in consequence we have a great number of 

 shrubs in cultivation that are not native. It is pleasing 

 to find that the book includes these, this fact adding large- 

 ly to its value. It is a twelvemo and contains five hun- 

 dred pages. (New York, Chas. Scribner's Sons, $2.00 net.) 



"Among Green Trees," by Julia Ellen Rogers is a book 

 that treats of all sides of the subject. The nature-study 

 side deals with various ecological problems ; the physio- 

 logical side with the processes of growth and reproduc- 

 tion ; the practical side gives clear directions for planting 

 and pruning trees; and the systematic side describes 

 about 125 species of native trees w4th special attention to 

 their individual characteristics. There are a large num- 

 ber of illustrations mostly from photographs, those illus- 

 trating specimen trees being unusually good. (Chicago, 

 A. W. Mumford, $3.00.) 



Dr. Henry Kraemer, professer of Botany and Pharma- 

 cognosy in the Philadelphia College of Pharmacy has re- 

 cently issued an attractive volume under the title of "A 

 Course in Botany and Pharmacognosy." The author 

 states that the book was written to meet his own needs 

 in teaching the subjects indicated, hence it is likely to be 

 of value to all others in the same line. The presentation 

 of the botanical part differs in many respects from the 

 usual treatment, much attention being given to the cell and 

 its contents. The special feature of the book is, of course, 

 to be found in the treatment of the drugs. This is divided 

 into two sections. In the one devoted to crude vegetable 

 drugs, each drug is described, its source indicated and its 

 constituents given. If the drug is often adulterated the 

 adulterants are named. The allied plants from which 

 similar drugs may be obtained are noted. In the section 

 of powdered drugs, keys are given for their identification 

 and the microscopical appearance of each is described. 

 This book will be of great value to such readers as are in- 

 terested in the various properties of our plants. (Phila- 

 delphia, Henry Kraemer, $3.50.)
