62 THE AMERICAN BOTANIST 



plant production from the physiological side and in conse- 

 quence throws a new and very different light upon the rela- 

 tion of the functions of plants to growth and reproduction. 

 The book, which is entitled "Plant Physiology with Reference 

 to Plant Production," begins with a chapter devoted to the 

 plant cell followed by several concerned with the water con- 

 tent of plants, absorption, transpiration, water movement and 

 related subjects. Then come additional chapters on the min- 

 eral requirements of plants, the uses to which they are put in 

 the economy of the plant, food making, digestion, transloca- 

 tion and the likes. The subjects of respiration, growth, repro- 

 duction and the seed each have chapters devoted to them after 

 which come still other chapters discussing the temperature, 

 light and chemical relations which with variation, heredity and 

 growth movements complete the book, covering more than 

 five hundred pages. Following each chapter are directions for 

 laboratory work to illustrate the subjects discussed together 

 with many references to the literature of the subject. The 

 book is illustrated with many excellent engravings and is bound 

 to prove of much usefulness in the class-room in addition to 

 being most entertaining and instructive to the individual 

 reader interested in the principles that underlie plant behavior. 

 The book is published by the Macmillan Company, New York 

 at $1.60 net. 



Messrs. Doubleday Page & Co., have recently added to 

 their books in the Garden Literature an instructive volume on 

 "Garden Planning" by W. S. Rogers. Though written by an 

 Englishman from an English point of view it is most useful 

 in planning and planting gardens on this side of the world 

 since it discusses the subject from an angle somewhat different 

 from that which obtains in American works. The book is es- 

 pecially full on the semi-artificial side including the making 

 of paths, sun-dials, trellises, summer-houses, arbors, pergolas, 

 fences, terraces, rock-work, hedges, garden seats, bridges and 

 many others. The text is a running commentary on good and
