Some Recent Forestry Books, 



Quite a number of important liooks on 

 forestry have appeared of lato, and tlie 

 Journal has pleasure in presenting to its 

 readers the s^hort reviews of some of the 

 most important of these which follow. 



New England Forestry. 



A significant mark of the advance of 

 forestry on this continent is the increase 

 in the literature of the subject. For years 

 foresters were so busy with practical mat- 

 ters that little or no time was left to write 

 on forestry, except in reports, bulletins and 

 similar publications, and the student in 

 search of information had to pick out the 

 information he wanted from a mass of 

 these. Of late, however, the foresters have 

 had, as it were, time to take breath, to 

 collect and systematize this information, and 

 a forestry literature has had time to grow 

 up, adapted to the conditions of this west- 

 ern continent. 



Naturally forest mensuration, owing to 

 its close connection with the utilization of 

 wood, claimed first attention, but of late 

 the would-be silviculturist has been receiving 

 his share, as shown by the publication, last 

 year, of Mr. H. S. Graves's Principles oj 

 Handling Woodlands, and lately of the 

 subject of this review, Messrs. Hawley and 

 Hawes' Forestry in New England* The 

 two books necessarily cover homething of 

 the same ground. The difference between 

 them lies in the fact that Mr. Graves's book 

 deals with the subject of silviculture (in the 

 broadest sense) along comparatively gen- 

 eral lines, while the authors of the latter 

 work have taken a specific region for treat- 

 ment and design to give owners of that 

 region practical directions for the treatment 

 of their forests, and, to a lester degree, of 

 disposing of the products. 



The importance of Messrs. Hawley and 

 Hawes 's book to Canadians lies in the fact 

 that forest conditions in parts of New Eng- 

 land are much the same as those in parts 

 of Canada. Forests in the state of Maine 

 require practically the same treatment as 

 thofe in New Brunswick and southeastern 

 Quebec ; the white pine lands of Ontario, 

 as well as the hardwood lands of the same 

 province, call for the same treatment as 

 corresponding areas in parts of New Eng- 

 land. The different forest regions are taken

up in Part II of the book. Chapter XIII 

 dealing with the Spruce region. Chapter 

 XIV with the Northern Hardwoods region, 

 Chapter XV with the White Pine area, and 

 Chapter XVI with the Sprout Hardwoods 

 area. Each of these is treated under the 

 following headings: — General Considera- 

 tions, Forest Types, Methods of Handling 

 the Forest, Logging Methods, Market Con 

 ditions. Industries, Character of the Land 

 and Timber Ownership, and Forest Protec 

 tion. Immediately preceding these chapters 

 is a short treatment of ' Present Forest 

 Conditions', which includes a section on 

 ' How to Find Information Applicable to 

 a Particular Tract. ' This should enable 

 a timberowner to decide to which division 

 his forest belongs, and under that division 

 he can identify the type of forest in which 

 his property is included, and further on in 

 the chapter he will find directions given as 

 to the proper treatment of this tract. 



The second part of the book contains also 

 chapters on ' The Progress of Forestry in 

 New England' and 'The Yield to be Ex- 

 pected from New England Forests under 

 Proper Management, ' and in the appendices 

 are given forest fire statistics, a biblio 

 graphy of works dealing with forestry in 

 New England, volume, growth and yield 

 tables and log rules 



Part I of the book deals with General 

 Forestry. Starting with Silvics (the general 

 consideration of the conditions affecting 

 the growth of forests) in Chapter 1, the 

 authors next take up, in Chapter V\, the 

 different silvicultural systems, under the 

 general divisions of reproduction of forests 

 from seed and reproduction from sprouts. 

 In Chapter III the different trees of the 

 region, e.g., White and Red Pine, Spruce, 

 Yellow Birch, etc., are dealt with separately. 

 Chapter IV contains a discussion of practi- 

 cal methods of planting and seeding of 

 forest trees, planting being strongly favor- 

 ed. Improvement Cuttings are discussed in 

 the next chapter under the headings of 

 Cleanings, Liberation Cuttings, Thinnings 

 and Damage Cuttings, with directions for 

 each and for cuttings in general. 



The next three chapters deal with Forest 

 Protection. A short chapter of some four 

 pages deals with damage from the larger 

 (vertebrate) animals. Chapter VII deals 

 with Forest Insects and Fungi, briefly treat 

 ed, e.g., the white pine \^eevil, sprucer 

 destroying beetle, spruce budworm and 

 'arch saw-fly (considerable use being made 

 of the work of Dr. C. G. Hewitt, as pub 

 iished in the 1911 report of the Canadian 

 Forestry Association) and, among the fungi, 

 the chestnut bark disease, white pine blister
