ious phases of nursery and planting technique and with methods of harvesting 

 and regeneration in the woods. In fact, the title : "Biological Management of 

 the Forest," would be none too broad for the field covered. 



In its geographic range, the book is thoroughly cosmopolitan, in line with 

 the author's well-known fondness for 'travel; frequent references are thus 

 made to conditions in the different regions of North America and to Europe, 

 which Dr. Baxter knows at first-hand. At the same time, there is a strong 

 "mid-western" tinge to the work, and particularly in the sections dealing with 

 the forest nursery and plantations, a rather large proportion of the case-his- 

 tories is taken from the Lake States. From the easterner's point of view this 

 has led to a few lapses, such as the footnote on p. 140 where, in citing the 

 number of acres planted in the Lake States region in 1937 there is appended 

 the remark : "Other agencies also planted trees during this period." This is 

 indeed a conservative statement, when one considers the extent of the reforesta- 

 tion projects in New York and other eastern states during the thirties. 



Special mention should be made of chapter VIII : "Relation of site and 

 care of shade and park trees to disease incidence," which occupies pp. 387-484. 

 There is some question, in this reviewer's mind, whether, in a book dealing 

 primarily with "woods forestry," nearly 100 pages should have been devoted 

 to shade trees — especially, when so many standard texts are available on the 

 subject. The insertion of this chapter was doubtless thought necessary, since 

 foresters, wherever found, are always expected to lend professional advice to 

 owners of ailing shade trees. From this standpoint the material is adequate 

 enough, though insect troubles are, of course, not included, making the sec- 

 tion seem incomplete in comparison with the special works. Numerous diseases 

 and injuries are described, including that from use of spray materials ; in this 

 latter connection, most of the attention is naturally given to fungicides. For 

 this reason, apparently, no mention is made of injury from dormant-oil insect 

 sprays, which has given arborists so much concern in recent years. 



One of the unusual features of the book is the section (pp. 208-210) on 

 rubber-plantations, having special reference to root-rot and its treatment. 

 Mention should be made, also, of the superb illustrations which amplify every 

 feature of the text : unique among these is the photo (p. 408 ) of twigs covered 

 with ice after a glaze storm. 



To summarize : Here is a work both scholarly and practical ; a sound 

 biological treatise and an extremely useful handbook, within the same text. It 

 should become the inseparable companion of all who seek a better understand- 

 ing of the forest, or who would apply forestry principles with a minimum of 

 avoidable errors.
