Studies of Trees in Winter Annie Oakes 

 Huntington. (Page), Boston, $3.50. 

 Generously illustrated with color plates 

 by Mary S. Morse and photographs by the 

 author, this book is an interesting and 

 valuable one, containing a description or 

 the deciduous trees of Northeastern Amer- 

 ica in their winter dress. The key for 

 identification is based largely on the con- 

 trasting characters of the buds, leaf 

 scars and stems, which always mark the 

 safest and surest course for tTiose who wish 

 to study and know the trees, and winter 

 is surely the best time to acquire such 

 knowledge. In his introduction to the 

 book. Dr. C. S. Sargent of the Arnold 

 Arboretum says : "A knowledge of trees, 

 the ability at least to recognize and iden- 

 tify them, adds vastly to the pleasures of 

 life. One who knows trees well meets them 

 like old friends; each season invests them 

 with fresh charm, and the more we study 

 and know them the greater will be our 

 admiration of the wonderful variety and 

 beauty which they display in winter." 



Birds of Field, Forest and Park, by Albert 

 Field Gilmore. (Page), Boston, $2.50. 

 Designed to stimulate among its readers 

 a desire to make the acquaintance in the 

 open of the birds it describes, this book 

 certainly meets its own requirements. It is 

 in no sense a treatise on ornithology, but 

 i>" the more valuable in that it reproduces 

 the atmosphere of the natural home of 

 the bird in field, forest and park by de- 

 scribing the conditions under which each 

 variety is found as well as their habits. 



plumage, songs, etc. About one hundred 

 and fifty varieties are described, including 

 those most common in eastern North Amer- 

 ica. Latin names are avoided in its phrase- 

 ology, as well as the purely technical terms 

 which are unfamiliar to the layman. 

 The volume contains the result of the 

 author's actual observations of bird life 

 covering a period of more than thirty 

 years.

Interesting Neighbors, by Prof. Oliver P. 



Jenkins. (Blakiston's), Philadelphia, 



$1.50 



This book contains sixty-two nature 

 stories for boys and girls the sort of 

 stories that small boys and girls relish 

 so keenly. Prof. Jenkins writes of bees, 

 bats and butterflies ; of birds and flowers, 

 even of toads, and whatever he touches 

 he makes real and full of understanding. 

 Nature gives to every time and season 

 some beauties of its own which become a 

 part of the life and experience of every 

 child. Natural objects themselves, even 

 when they make no claim to beauty, ex- 

 cite the feelings and curiosity of the young 

 and occupy the imagination. The child 

 mind is not educated by argument, but by 



events, and Nature pleases, attracts, and 

 delights while she instructs. 



Watched by Wild Animals, by Enos A. 



Mills. (Doubleday, Page & Company), 



Garden City, $2.50. 



Replete with descriptions of nature char- 

 acteristic of Mr. Mills' enthusiasm for his 

 subject, this book appeals strongly to all 

 admirers of animals, nature and good writ- 

 ing. The author. says that when you go out 

 purposely to observe wild animals in their 

 native haunts, you are watched a great deal 

 more than you watch. .Mmost invariably, 

 he says, he has found animals' tracks in his 

 wake as he traversed wild country, and 

 through other signs known to the woods- 

 man, he has known that the animals have 

 been spying upon him, and he tells about 

 it in his own inimitable way. 



"The Valuation of American Timberlands," 



by K. W. Woodward. (Wiley), New 



York. $3.00. 



A study of the factors involved in esti- 

 mating timber values is made by Prof. K. 

 W. Woodward, head of the New Hamp- 

 shire College forestry department, in a 

 volume entitled "Valuation of American 

 Timberlands," which has just been pub- 

 lished. The book was written to supply in- 

 formation of practical value to investors, 

 timber cruisers and stuaents of forestry 

 throughout the country. 



Professor Woodward's book represents 

 one of the few attempts that have yet been 

 made to gather in one volume descriptions 

 of the forest types of the United States and 

 its outlying territories. The author draws 

 not only upon his knowledge of New Eng- 

 land forest conditions but upon a previous 

 service with the United States Forest Serv- 

 ice and a wide acquaintance with woods- 

 men over the' country in depicting types 

 of trees which range from the northern 

 spruce, hardwoods and white pine of New 

 England to the cypress of the Southern 

 bottomlands, the chapparal of Arizona, the 

 redwoods of the Pacific coast and the dip- 

 terocarps of the Philippines. 



Agricultural Conference Report The 

 report of the National Agricultural Con- 

 ference as made by Secretary of Agricul- 

 ture Wallace to President Harding is to be 

 issued as a public document. President 

 Harding transmitted the report to the ag- 

 ricultural committee of the House, which 

 presented it to the House with the recom- 

 mendation that it be printed as a public 

 document. The House approved the re- 

 commendation. The publication will con- 

 tain the addresses delivered before the 

 conference and the reports of the various 

 committees. Persons who are interested 

 may obtain copies of the document through 

 their congressmen.
