Wood, by G. S. Boulger. Edwin Arnold, 

 London. Placing in tlie hands of those 

 for any reason interested in the subject 

 of wood, its supply-sources and its 

 uses, in a single volume, a mass of well- 

 prepared information hitherto unavail- 

 able except in a large number of scat- 

 tered publications. The author has 

 treated his subject rather more from 

 the scientific standpoint than the popu- 

 lar, and the work may, therefore, pos- 

 sibly not reach so wide an audience as 

 it would otherwise have done. The 

 volume is divided into two parts, with 

 four appendices. The first part treats 

 of the origin, structure and develop- 

 ment of wood; the recognition and 

 classification of wood; its defects; se- 

 lection, durability and seasoning; uses, 

 sources of supply, and methods of 

 wood testing; while the second part 

 has to do with the sources, characters 

 and uses of the woods of commerce. 

 The volume is well printed, is illus- 

 trated with numerous handsome half- 

 tone engravings and a large number of 

 drawings, and is attractively put to- 

 gether. 



Our Trees: How to Know Them, by 



Arthur I. Emerson and Clarence M. 

 Weed. J. B. Lippincott Company, 

 Philadelphia and London. Here is a 

 volume that will prove invaluable to 

 the student of forestry who is just be- 

 ginning, and who wants to gain as 

 rapidly as possible the rudimentary in- 

 formation that will enable him or her 

 to recognize the trees of the forest. 

 Little attention is given to the scientific 

 side of the subject; in fact, the Latin 

 names of the trees are only given m 

 a sub-caption beneath the illustrations. 

 Of these there are almost two hun- 

 dred, and each illustration shows sev- 

 eral figures of the same tree — the 

 trunk, a branch of the foliage, and the 

 fruit, seedpod or cone, as the case 

 rnay be. The text is written in a de- 

 lightfully understandable style, and 

 the illustrations are such as to make 

 the subjects easily recognizable. The 

 book is a handsomely gotten up vol- 

 ume, .and should be in lae library of 

 every man or woman who is inter- 



ested in the vital question of forest 

 conservation. 



The Relation of the Southern Appala- 

 chian Mountains to Inland Water Nav- 

 igation; Forest Service Circular No. 

 143. This is worthy of more than pas- 

 sing notice, it being a study, by M. O. 

 Leighton and A. H. Horton, of the 

 United States Geological Survey, of the 

 matter which forms the title of the 

 pamphlet. The work gives the re- 

 sult of investigations made by the 

 Geological Survey covering the whole 

 territory of the Atlantic seaboard from 

 the Potomac River southward; it shows 

 clearly the vastly mcreased use that 

 can be made of the rivers of this en- 

 tire region, for transportation pur- 

 poses, when the crest of the Appala- 

 chian system is placed under Govern- 

 ment supervision and the process of 

 total deforestation is ended. I'he tab- 

 ulations contained in the work may be 

 depended upon as being exact and ac- 

 curate; and the pamphlet is a most 

 valuable reference work.
