Caribou Migration in Xewfoundlancl."" It is an excellent example 

 of what a sportsman can accomplish with a camera. It repre- 

 sents the achievement of six years of eltort, live fruitless, one 

 finally successful. The admirable pictures are so infinitely su- 

 perior to the caricatures that illustrate so many books on animal 

 life, i)ictures of an animal first killed by a rifie and then photo- 

 graphed either as a carcass or stiffly-posed in a i)rop])ed-up 

 attitude. Speaking- of the caribou, he says, "The leads or roads 

 which the\" follow have been in use year after year, perhaps for 

 hundreds or thousands of years, for in many places deep fur- 

 rows are worn in the rocks by the hoofs of the countless 

 thousands.'' There are suggestive chapters on methods in bird 

 and animal ])hotogra])hy and on camping out. 



Biology, an Introductory Study. \\y Herbert W. Conn. 

 Pages X-f 425, Silver, Burdett & Co. 



This book seems like almost an ideal text to put into a high 

 school course. It gives in an entertaining wa\', at the same time 

 with scientific accuracy, the main themes of modern biology. 

 One misses with gratitude the stereotyped morphological treat- 

 ment of plants and animals, — the customary university and col-

 the attempt is to present the reactions and functions of the 

 organisms and to point out the chief applications to human prob- 

 lems both social and industrial. Dr. Conn is to be congratulated 

 on his ability to exclude the non-essentials. 



Plant and Anitnal Children and IIoik' Tlicy Crow. By Ellen 

 Torrele. 'i'M) pages. D. C. Heath (^ Co. 



This book is written es]:)ecially for the pupils of the ele- 

 mentary schools. It aims to make clear the ideas of evolution, 

 heredity, variation, efifect of environment, and the evolution of 

 sex, without once mentioning these names. In this it is a de- 

 parture from that tradition in education which has held that 

 such ideas are the exclusive prerogative of the college-bred. 

 There is no doubt that children are greatl}- interested in the study 

 of plant and animal life and are quite able to comprehend the 

 subject matter of botan_\- and zoology, as the author >tates in 

 her preface, but it is quite (|uestionablc how much the average 

 teacher will be able to get out of the class with this book as a 

 text discussing such forms as the green algae, fungae. marchantia 

 and its reproduction, amoeba and its allies, hydra, etc. The work
