The trees of Great Britain and Ireland, II. J. Elwes and A. Henry {Edin- 



huryh: Authors. JOOG. pp. Xyi-\-:^00. yy/.v. (il). — This is volume 1 of an extensive 

 treatise, in whicli the authors aim to give a complete account of all the trees 

 either native to or cultivated in Great Britain which have attained or seem 

 lilvcly to attain sufficient size to warrant their consideration as timber trees. 

 About 30() si>ecies are to be considered, the most of which the authors state 

 have lieen the subject of their personal study. 



The present volume consists of 2 parts. In part 1 the several species of the 

 following genera are identified: Fagus, ailanthus, sophora, araucaria, ginkgo, 

 liriodendron, spruce-firs, taxus, cryptomeria, pyrus, taxodium, and thuya. The 

 history and distribution of each in various countries are considered and an 

 .'iccount is given of the cultivation, soil, and location, together with descriptions 

 of the remarkable trees of those varieties which occur in Great Britain. Atten- 

 tion is also paid to the use of the various trees for timber or other purposes. 



Part 2 is devoted to illustrations of the species discussed, including specimen 

 trees and interesting woods and i)lnntations. 



Location, date of latest proclamation, and area of the National forest 

 reserves in the United States, Alaska, and Porto Rico ( U. *S'. Dept. Ayr., 

 Forest Hvrv. [C'/rc], Fch. 1, 1001, pp. //). — The data indicated in the title are 

 l)resented in tabular form. 



The total number of forest reserves in the United States is 13G, with an area 

 of 128,850,101 acres ; in Alaska 2, with an area of 4,909,880 acres, and in Porto 

 Rico 1, with an area of 05,950 acres, making a grand total of 1.39 forest reserves, 

 including 128,825,991 acres. 



The timber supply of the United States, R. S. Kellogg ( JJ. 8. Dept. Apr., 

 Forest Scrr. ('ire. 91\ pp. 16. fif/s. 2). — This circular, a brief summary of which 

 has l>een previously noted (E. S. R., 18, p. 944), contains a discussion of the avail- 

 able timber suj)ply of the United States and the length of time it will last at 

 the present rate of cutting. A large number of statistics are brought together 

 from different sources as to the annual output of forest products, the lumber 

 cut, the geographical distribution of the total lumber product, and estimates of 

 the stumpage of the United States at various periods, together with a recent 

 estimate of the stumpage of the Pacific coast. 



A map is given indicating the general distribution and character of the 

 original forests of the United States, which shows the natural timber areas of 

 the coinitry to be embraced in 5 groups of States, as follows: Northeastern 

 States, Southern States, the Lake States, the Rocky Mountain States, and the 

 Pacific States. In the 2 latter groups practically all the timber-producing trees 

 are coniferous, while in the first 3 groups both conifers and hard woods are 

 found. 



Four types of forests are produced in the Southern States. The swamp areas 

 of the Atlantic and Gulf coasts furnish cypress and hard woods, and the plains 

 from Virginia to Texas southern or yellow pine. Pure hard woods are found in 

 the plateau encircling the Appalachian range, while the higher ridges contain 

 spruce, white pine, and hemlock. The Lake States still contain many hard-wood 

 forests in the southern i)ortions, and pine, tamarack, cedar, and hemlock in the 

 northern areas. The chief timber trees of the Rocky Mountain forests ai*e 

 western yellow and lodgepole pine, and those of the Pacific forests are Douglas 

 firs, western hemlock, sugar and western yellow pine, redwood, and cedar. 



The author asserts that it is unquestionably safe to say that our present 

 annual consinnption of wood in all forms is from 3 to 4 times as great as the 

 annual increment of our forests. A chart is given showing the course of prices 

 of white pine, yellow poplar, and hemlock since 1887 and of yellow pine since 

 1894. The most liberal estimate as to the wooded area of the United States
