THE INDIA RUBBER WORLD 



69 



The great variety of instruments for recording and controlling 

 temperature and pressure during vulcanization of rubber goods 

 is given in detail. The book closes with a complete story in 

 text, half-tone and outline illustration of the apparatus and ma- 

 chines used in the rubber laboratory; while the last, and to many 

 the most important feature of this valuable book is the compre- 

 hensive and carefully prepared subject index. 



HENDRICK'S COMMERCIAL DIRECTORY OF THE UNITED 

 States for buyers and sellers. S. E. Hendricks Co., Inc., New York, 

 1915. [Quarto, 1,503 pages. Price 10 dollars.] 

 This commercial register was founded in 1891 and the 

 present volume is its 24th annual edition. Attention has often 

 been called in this department to the wonderful completeness 

 of this monumental work and the accuracy with which the 

 compilation is made. The present volume contains 1,503 

 pages. This is about 90 pages less than the edition of a year 

 ago, but this does' not indicate that there is less matter. On 

 the contrary, the edition of a year ago has been revised with 

 extreme care and everything eliminated from it that was not 

 of a strictly current and useful character. So that while this 

 present volume contains fewer pages than its immediate pre- 

 decessor it has in reality quite a good deal of new information 

 that has not hitherto appeared in this register. 



Another pleasing feature of this latest edition is the fact 

 that it is printed from entirely new type, which gives every 

 page a clean and attractive appearance. This edition is also 

 bound in leather instead of in cloth, as has hitherto been 

 the case. 



Probably most of the readers of this publication are familiar 

 with this standard work, but to any who may not be it need 

 only be stated that it is a complete register of practically 

 every American industry, giving under a comprehensive sys- 

 tem of classification and sub-classitication the producers, 

 manufacturers, dealers, and large consumers connected with 

 all the important .\merican industries, including railroading, 

 engineering, contracting, architectural construction, mining, 

 quarrying, and every line of manufacture. To show the com- 

 pleteness of the work, it might be added that the index alone, 

 printed four columns to a page, occupies 147 pages. 



NEW TRADE PUBLICATIONS. 



AN ELLTISTHATED CATALOG OF CHEMICAI. LABOHATOKY SUPPLIES. 



AN illustrated, descriptive catalog of chemical and assay labo- 

 ratory supplies (483 pages) bound in loose leaf covers, has 

 been received from Eimer & Amend, 205 Third avenue. New York. 

 The book is a series of special circulars or pamphlets fastened in 

 adjustable covers. This form has been adopted pending the 

 publication of a new edition of the regular bound catalog, which 

 apparently must wait for settled conditions in the matter of 

 foreign importations. In certain lines .\merican-made substi- 

 tutes are being supplied. 



A MEMOEANDtTM BOOK FROM WOOD-MILNE, LIMITED. 



Wood-Milne, Limited, of Preston, England, whose specialties 

 are rubber heels, solid pneumatic tires and golf balls, have favored 

 their friends and customers with an attractive little memo- 

 randum book, 3Vj X 6 inches, or in other words just con- 

 venient pocket size. It contains the calendar for the present 

 year and for 1916, a page where the owner can jot down certain 

 personal matters like his telephone number, watch number, size 

 of gloves, and other similar memoranda that is liable to escape 

 one's memory, and, in addition, has several pages of gen- 

 eral information, some of it useful chiefly to people in England, 

 but the rest equally useful everywhere else. The remainder of 

 the book consists of blank pages for memoranda, with a number 

 of leaves specially ruled for an expense account. The pages 

 are finished with a gilt edge and inserted in suede leather 



covers provided on the inside with pockets for hills, stamps and 

 tickets — altogether a useful little volume.

This is a 126-page, illustrated manual published by the Under- 

 writers' Laboratories, Inc., Chicago, for the benefit and service of 

 users of rubber insulated wires and cables for electric lighting and 

 power circuits. This manual, which appears to have been prepared 

 with great care, describes in detail the system of label service of 

 the Underwriters' Laboratories, the specifications and tests pre- 

 scribed by the National Electric Code for rubber insulated wires 

 and cables, the Laboratories' methods for testing rubber com- 

 pounds used for such electrical insulations and their system of 

 following-up and testing market samples of articles bearing 

 their labels. 



To facilitate the insertion of additional matter this manual has 

 been bound in loose leaf form, a very obvious convenience. 



This pamphlet of 24 pages is from the pen of Dr. -\. J. Ultee, 

 and is published in the Dutch language by H. van Ingen, Sura- 

 baya, Java. It treats of the different chemicals used in the prepa- 

 ration of rublier— coagulants, anti-coagulants and bleaching and 

 disinfecting agents. A brief appendix describes some of the 

 diseases and pests affecting plantation Hevea. 



DISEASES AND PESTS OF THE HEVEA BBASILIENSI8 IN JAVA. 



This is a report by Dr. A. A. L. Rutgers and Dr. K. W. Dam- 

 mermann of the work of the Department of Plant Diseases in 

 the Netherlands Indies, published by the Department of Agricul- 

 ture at Batavia, in the form of a paper-covered booklet, quarto 

 size, 45 pages. It is published in Dutch and in addition to the text 

 has a number of good-sized illustrations showing the effect upon 

 the Hevea tree of the various diseases and pests described. 



Like many trees growing far away from their aboriginal land, 

 the Hevea Brasiliensis, in the plantations of Java, is suHject to 

 a number of more or less serious diseases affecting its roots, 

 trunk, branches and leaves. Animal pests such as wild pigs, 

 rabbits and crickets also cause considerable damage to plantation 

 Hevea. The authors have made exhaustive studies of these 

 diseases and pests, of their causes and remedies and the results 

 of these studies are reported in this book, which is well illustrated 

 by photographic cuts and should be of important service to rubber 

 planters in the East. 



GOODRICH NEWS SERVICE. 



The news service department of The B. F. Goodrich Co. is 

 publishing photographs, in the form of posters 13 inches square, 

 of current events of general interest showing, incidentally, the 

 wide use of Goodrich tires. These posters are furnished to 

 Goodrich dealers, together with gummed strips for pasting them 

 in their show windows. The size and topical interest of these 

 pictures arc sure to attract the attention of passersby and fix 

 the Goodrich trade marks in the minds of those among them who 

 are tire users.

A LEATHER CASE FOB A BUNCH OF KEYS. 



The Somerset Rubber Reclaiming Works, of New 

 New Jersey, has recently distributed a useful little souvenir in 

 the shape of a leather cover for the bunch of keys which every 

 well-ordered man carries. A feature of value lies in a metal 

 check, stamped with a number, which is registered at the Somer- 

 set works. Should the keys be lost, they would naturally be 

 returned to the company, which in turn would be able to locate 

 the owner. 



"Rubber Machinery," Mr. Pearson's newest book, filled with 

 valuable information for rubber manufacturers, is now ready for 

 mailing. Price, $6.
