THE WHOLE ART OF RUBBER GROWING. BY W. WICHERLEY, 

 F.R.H.S. Philadelphia: J. B. Lippincott. London: The West Strand 

 Publishing Co., Limited. 191L [Clotli. 8vo. Pp. 154. Price $1.50. J 



This book is intended as a handbook and guide in the selection 

 and planting of those species of rubber-yielding trees which can 

 be successfully cultivated in countries and climates other than 

 those to which they are native. The book is primarily for the 

 use of planters in the Middle East and Far East. While avoiding 

 as far as possible technicalities, it goes into detail so as to be 

 of practical value to the planter. It treats of the Hevea Brasili- 

 ensis, its remarkable growth, the preparation of a clearing, the 

 best methods of planting, of weeding and cultivation, and the 

 most successful tapping systems. The book also gives a great 

 deal of information regarding the Manihot Claziovii, and the 

 Ficus. Chapters are devoted to Castilloa, Funtumia^ guayule, 

 jelutong and various other rubbers. Some space is devoted to 

 the interesting Soya bean. For its 154 pages it gives a great deal 

 of information and is generously illustrated. 



LOS SUCCEDANEOS DE LA GOMA ELASTICA Y EL GUAYULE DE 

 Mexico. (Surrogates of Rubber and Mexican Guayule.) By Professor 

 Julius Morpurg. 8vo, paper; 1910; 12 pp. Secretaria de Fomento, 

 Mexico City. 



This brief treatise, brought out in German on the occasion of 

 the inauguration of the first "Exposition of Mexican Products" 

 at Trieste in 1908, has been deemed worthy of translation into 

 Spanish and of publication by the Mexican Ministry of Com- 

 merce, having appeared in 1910 under its new form. 



Seeing that it was written three years ago, due allowance 

 must be made for intervening developments, which, while remov- 

 ing apprehensions as to a contingent scarcity of genuine crude 

 rubber, have likewise enriched the technical literature dealing 

 with rubber and rubber surrogates, and have confirmed Pro- 

 fessor Morpurg's assertion that "we now know rubber in the 

 same way as we do lubricants, rosins, gums and other vege- 

 table products used technically." 



At the same time he remarks that rubber substitutes in fact 

 represent a falsification rather than a substitution, and that the 

 question of cheap rubber has not been solved by chemical 

 products. 



After dealing with the various botanical facts the author re- 

 marks that it is scarcely twenty years since attention has been 

 given to seeking rubber in various plants other than those from 

 which it had been hitherto derived. In this connection he refers 

 to the success which has of late years attended investigations as 

 to various exotic plants and notably Guayule. Two samples had 

 been sent to the Trieste Exposition, one of which had been 

 analyzed. 



In his concluding words Professor Morpurg remarks that 

 Guayule deserves the most serious consideration, in view of 

 its combining perfectly with rubber, and being fitted for vul- 

 canization, while its resistance is superior to that of substitutes 

 or any other surrogates. 



THE COPPER HANDBOOK, A MANUAL OF THE COPPER INDUS- 

 try of the World (Volume 10), Compiled and Published by Horace J. 

 Stephens, Houghton, Mich. [Board covers, 8vo., 1,902 pages.] 



This is certainly a voluminous book, as the number of pages 

 given above will indicate ; nor has any attempt been made to 

 swell the number of pages by the use of unusually large type or 

 unnecessary leading. It is a book of solid information. Nearly 

 1,600 of the 1,900 pages are devoted to the description of rub- 

 ber mines and mining companies in all parts of the world. 

 There are over 8,000 of them so described ; some of them of 

 merely historic importance receiving only two or three lines, 

 while the great Anaconda Mine, which yields '/i of all the 

 world's supply of copper occupies twenty-one pages. 



To investors in copper stocks this information about mines 

 and mining properties will probably be the most interesting mat- 

 ter in the book — but to other people, the preliminary chapters 

 filling about 250 pages on the general topic of copper, giving 

 its history, its geology, chemistry and mineralogy, the methods 

 of mining, the uses of copper and the general distribution of 

 copper over the world will prove the most interesting. The 

 chapter on geology giving the different scientific theories that 

 account for the presence of metals in the earth is well worth 

 the reading, while the chapter on the uses of copper showing 

 the myriad purposes to which this metal is put, is full of in- 

 formation. 



Of course, its chief use is for the conveyance of electricity. 

 In addition to power, light and traction lines, and telegraphs and 

 telephones, copper wire is used to the extent of millions of 

 pounds for minor electrical systems, including messenger calls, 

 fire alarins, burglar alarms for banks and residences. Copper 

 is being used in large quantities constantly in building construc- 

 tion, for roofs, and cornices, and ornamental panels, and for 

 bronze grill work. 



The publisher sends this book to any address without advance 

 payment of any sort and subject to a week's inspection. The 

 price when bound in green cloth covers is $5.00, in library 

 morocco, $7.50. 



HENDRICKS' COiMMERCIAL REGISTER OF THE UNITED STATES 

 for Buyers and Sellers. New York: Samuel E. Hendricks Co., No. 74 

 Lafayette street. [Board. Large 8vo. Pp. 1442. Price $10.] 



For twenty years the publishers have issued this directory, 

 and it has grown with every year. This year it gives 124 pages 

 of new matter not found in last year's directory, while the 

 entire volume has been revised and made correct up to the 

 date of issue. Some conception of the magnitude of this book 

 may be had from the fact that the index covers 108 pages, with 

 400 classifications on each page. The total number of classi- 

 fications is 45,000, giving a complete list of the manufacturers 

 of agricultural, engineering, electrical and mechanical articles 

 and those used in kindred trades and professions. 



An itnportant feature of this register is the simplicity of its 

 classifications. All manufacturers are first classified under the 

 general- name of the special trade in which they are engaged. 

 They are then subdivided under as many classifications as there 

 is variety in their products. By this system the book is made 

 particularly valuable to purchasers. There are all told 350,000 

 names and addresses in the book. In addition to names and 

 addresses the book gives much information regarding the firms 

 mentioned and the nature of their products. 



CHILTON AERO DIRECTORY CONTAINING CLASSIFIED LISTS 

 of Manufacturers of Air Crafts of All Kinds. Philadelphia: Chilton 

 Co. [Paper. 8vo. Pp. 88 and cover. Price $1.] 



If anyone doubts the interest in this country in aeronautics 

 he has only to look over the 88 pages of this directory to be 

 undeceived. Aeronautics has in reality become not only a good 

 deal of a science but also a very sizeable industry. This 

 directory contains not only lists of manufacturers of all man- 

 ner of aerial vehicles and of their parts and accessories, but 

 it also includes lists of the aero clubs in this country, giving 

 the names of their officers and members, lists of licensed pilots 

 and aviators, together with the world's aviation records. It 

 is an interesting fact that the manufacturers of aeroplanes 

 proper fill over three pages of the directory, with over thirty 

 names to a page. This is exclusive of manufacturers of parts 

 and accessories. The directory shows about 15 aeronautic 

 schools" in different parts of the country.
