256 JOURNAL OF FORESTRY 



As the author says in the preface, while, of course, statutory 

 law is subject to constant change, and can be ascertained only by 

 reference to the latest statutes, the interpretations by courts are more 

 stable and certainly the attitude of the courts which appears in ad- 

 judged cases can be traced most satisfactorily in this volume. 



Wherever a course on business law is given to foresters, this 

 volume will be needed to bring the examples illustrating the principles.

Tree Wounds and Diseases: Their Prevention and Treatment. 

 By A. D. Webster. J. B. Lippincott Company, Philadelphia ; Williams 

 and Norgate, London. 1916. Pp. 215. 



Lippincott publishes in standard form, clear print, with wide 

 spacing and good illustrations, this volume from the pen of an English 

 author. In this country, which has lately been flooded with literature 

 on the subject of tree surgery, the reason of the author for writing 

 the book, because "no work of a similar kind has been published/' 

 can have reference only to the outward appearance. To be sure, 

 besides the stock in trade of the tree surgeon, there is considerable 

 discussion of pathological conditions, including fungus and insect 

 attacks and injuries from animals, and advice how to meet them. 



The physiological discussions are not always correct and complete 

 enough even for a book of this more popular character. 



In the prescription for treatment we have, in a superficial looking 

 over the pages, found nothing essentially reprehensible nor anything 

 specially new. The expositions are of common sense and simple 

 character. New to the reviewer is a mixture of four parts sawdust 

 with one part asphalt, to be used instead of concrete for filling, as 

 being more elastic. 



The subject matter is divided into thirteen chapters. A general 

 discussion of policy in the management of decaying trees covers ten 

 pages ; the treatment of hollow trunks, seventeen pages. A rather long 

 chapter of twenty-three pages discusses the supporting of heavy and 

 diseased branches, which seems to be favored beyond desirable limits of 

 preserving the decrepit. Bark injuries are treated on eleven pages. The 

 chapter on pruning diseased trees is rather scantily treated on ten 

 pages. It leaves out of consideration the proper pruning practice to 

 prevent disease, and this is not even referred to in a later chapter on
