Studies of Trees. J. J. Levison. Pp. x + 253 John Wiley 

 & Sons, Inc. $1.60 



The number of books is evidence that the tree is excellent 

 Nature material. In all of these books, the chief endeavor is to 

 present the characteristics of the different species that render 

 identification easy. That is well done for the common trees in 

 this book. The first three chapters, containing 90 pages, are 

 devoted entirely to this matter. Then comes a chapter on the life 

 history of the tree, next an excellent chapter on what and how to 

 plant, giving the lists of trees that are good for lawn, street, wood- 

 land. Chapter 6, on the care of trees, tells how to protect from the 

 numerous insect pests, and gives a list of the more common sorts. 

 It describes the common tree diseases, also, and the methods of 

 prevention, as well as the treatment of injured trees. Chapter 7, 

 on forestry, is one that every public school pupil should read, for it 

 presents concisely the reasons for, and the methods of conservation. 

 Chapter 8 is on common woods. The numerous excellent illustra- 

 tions greatly add to the value of the volume. 



The author is to be congratulated on putting so much serviceable 

 material into such small compass. 



The Birds of Connecticut. By J. H. Sage, L. B. Bishop, assisted 

 by W. P. Bliss. 



This is Bulletin No. 20, of the State Geological and Natural 

 History Survey, and is one of the publications that every bird 

 student will want to add to his library. There is systematic treat- 

 ment of the birds of Connecticut, with brief description, dates and 

 places where recorded, nesting dates, and information regarding 

 migration. A very full bibliography, covering some 58 pages, is 

 given. Nearly a hundred pages is taken up with the discussion of 

 the economics of Connecticut birds, and a mass of facts is given for 

 each group, and in many cases for specific birds, showing how 

 valuable the ordinary birds are in keeping under control insect and 

 weed pests. This is not only a record of many new observations, 

 but there is given also a digest of many of the observations that 

 have hitherto been made on particular species. Application for 

 this bulletin should be made to the State Librarian of Connecticut.
