THE GUIDE TO NATURE. 



IlTERARY 



BIOGRAPHICAL 



The Biota of The Sail Bernardino Mountains. 



By Joseph Grinnell. Berkeley, Califor- 

 nia: The University Press. 



This University publication interestingly 

 and scientifically tells the territory visited 

 and the life zones and discusses the bird 

 population (one hundred and thirty-nine 

 species) and the influences modifying it, 

 the plants of the region, the mammals 

 (thirty-five species) and the reptiles (twen- 

 ty species). 



The author is a well known naturalist, and 

 has excellently done the work assigned to 

 him. 



Species and Varieties, Their Orieiu by Mu- 

 tation. By Hugo DeVries, Professor of 

 Botany in the University of Amsterdam. 

 Edited by Daniel Trembly MacDougal. 

 Second Edition. Chicago: The Open 

 Court Publishing Company. 



"Professor DeVries has rendered an addi- 

 tional service to all naturalists by the pre- 

 paration of the lectures on mutation 

 published in the present volume. A perusal 

 of the lectures will show that the subject- 

 matter of "Die Mutationstheorie" has been 

 presented in a somewhat condensed form, 

 and that the time which has elapsed since 

 the original was prepared has given oppor- 

 tunity for the acquisition of additional facts, 

 and a re-examination of some of the more 

 important conclusions with the result that 

 a notable gain has been made in the treat- 

 ment of some complicated problems. 



"It is hoped that the appearance of the 

 English version of the theory of mutation 

 will do much to stimulate investigation of 

 the various phases of the subject. This 

 volume, however, is by no means intended 

 to replace, as a work of reference, the larger 

 book with its detailed recital of facts and 

 its comprehensive records, but it may 

 prove a substitute for the use of the general 

 reader." 



The Primary Factors of Organic Evolution. 



By E. D. Cope, Ph. D. Chicago: The 

 Open Court Publishing Company. 



From I he mass of facts accumulated by 

 biologists, the author has selected such as, 

 in his opinion, throw a clear light on the 

 problem of organic evolution, especially 

 that of the animal kingdom. He has de- 

 pended chiefly in his demonstrations on 

 paleontologic research. 



Commercial Violet Culture. A Treatise on 

 the Growing and Marketing of Violets 

 for Profit. By B. T. Galloway,, Chief 

 of the Bureau of Plant Industry, United 

 States Department of Agriculture. Sec- 

 ond Edition, Revised. New York City: 

 A. T. DeLamere Printing and Publish- 

 ing Company, Ltd. 



This hand book gives all details for pre- 

 paration of soil, construction of houses and 

 frames, care of plants and marketing of 

 the flowers. It is almost wholly from the 

 business point of view, but contains much 

 of interest to the amateur. 



The author shows, however, that under 

 the dollars and cents is a real love for 

 nature. He says, "From the facts given it 

 will be seen that no big fortunes are to 

 be made in violet growing; but if a man 

 loves Nature and that quiet and peace 

 which work with her should always bring, 

 there is a chance here to open her doors. 

 Thus a love for all that is good and beauti- 

 ful may be cultivated and a respectable 

 living made at the same time." 



Goldfish Breeds and Other Aquarium Fishes. 



Their Care and Propagation. By Her- 

 man T. Wolf. Philadelphia, Pennsyl- 

 vania: Innes & Sons. 



This is a new and thoroughly up-to-date 

 book on the aquarium and its inhabitants. 

 It represents the total expei ; ence of the 

 aquarium enthusiasts comprising the Aqua- 

 rium Society of Philadelphia and the scien- 

 tific knowledge of a number of members of 

 the famous Academy of Natural Sciences. 

 The author is an active member of both 

 organizations and as secretary of The Aqua- 

 rium Society for a number of years had 

 ideal opportunities for writing just such a 

 complete and practical book. 



In addition, Mr. Wolf is an artist of un- 

 usual ability. His illustrations of aquarium 

 life are extremely natural and beautiful. 



Altogether this is far the best aquarium 

 book that has ever appeared in any language 

 and should be owned by every aquarist and 

 naturalist. 



Every point mentioned is taken up thor- 

 oughly and practically. 



The book is 7 x 10y 2 inches, fine paper, 

 gilt top, 390 pages and contains 280 life- 

 size illustrations, including a frontispiece in 

 colors. 



The illustrations alone are worth the price 

 of the book, $3.00. 



Books may be kept on one day's approval. 

 Money refunded if not entirely satisfactory.
