Guide Book of the Western United States Part A, Northern 

 Pacific Route. By Marius R. Campbell and others. $1.00. 



This is bulletin No. 611, of the United States Geological Survey. 

 A series of such bulletins is being issued with the view of putting 

 into non-technical language such information as would interest the 

 traveller in the several regions covered. This particular one takes 

 the Northern Pacific Route. Excellent maps give consecutive 

 sections of the route travelled, with descriptions of interesting 

 features along the way accompanying them Much of the informa- 

 tion is naturally physiographic, with sufficient geological informa- 

 tion so that one may understand the surface features. 



Many of the important towns are noted, with information regard- 

 ing their activities. The book is well illustrated, and the traveller 

 will gladly possess these guide books as an aid to intelligent travel. 



Practical Zoology. By Robert W. Hegner. Pp. xv + 495. 

 Macmillan Company. $1.40. 



This book is cast on systematic lines. The first hundred pages 

 are devoted to the economic insects. Then comes a chapter on 

 classification, after which the rest of the arthropods are considered. 

 Then follow chapters on the molluscs, the worms, the echinoderms, 

 ccelenterates, etc., with about half of the book devoted to the 

 vertebrates. 



As a high school text, this should certainly be an improvement 

 on most of the systematic treatises that have thus far appeared, 

 for it deals with phases of the subject that are of direct interest to 

 the average pupil. While many of the animals mentioned are 

 not those of the child's immediate environment, most of them are, 

 and natural history is of interest to the boy and girl even when the 

 forms described are those of distant lands. It is a zoology that the 

 nature student will use often as a reference book, and I know of 

 none that would serve in the average school library better. If it 

 is combined with a good deal of field work or is used in connection 

 with laboratory work, it certainly should prove an excellent high 

 school text. The book is well illustrated. Many of the illustra- 

 tions, especially those in the chapter on birds, are from^ the 

 author's own photographs.
