COMMUNICATIONS OF THE NETHERL.\NnS GOVERNMENT IN- 

 "^tititle for Aiivisins the Rubber Trade ami the Rubber Industry 

 Established at Delft. Part 1. [Paper cover. 36 pages.] 



In our issue of April, 1917, we reviewed a collection of im- 

 portant papers recording researches made in the above institute 

 and published by the Trade Department of the Netherlands 

 Ministry of Agriculture, Industry and Commerce, under the 

 title. "Mededcelingen van den Ryksvoorlichtingsdienst ten be- 

 hoeve van den rubberhandcl en de rubberni.iverhcid te Delft." 

 These papers were preceded by an introduction showing the re- 

 lation between the various subjects treated. The International 

 Association for Rubber Cultivation in the Netherlands Indies, 

 recognizing that the fact that these valuable studies were writ- 

 ten in Dutch would prevent their wider perusal, now offers an 

 elaboration in English of this introduction. This first of the six 

 parts in which the English version is to appear, is now ready 

 for the public. It treats "The Examination of Latex and the 

 Valuation of Raw Rubber According to the Exterior," seven 

 sub-divisions being as follows : 



I. The state of colloidal aggregation of the rubber in the 

 latex. 



II. Determination of the caoutchouc percentage of latex. 



III. The non-caoutchouc compounds of the latex. 



IV. The different methods of preparing rubber. 



V. External valuation of raw rubber. 



VI. Spots on raw rubber. 



VII. Transparent raw rubber. 



While the introduction mentioned facts not elsewhere pub- 

 lished, this elaboration contains points not found in the separate 

 papers of the complete Dutch work. On the other hand, the sub- 

 jects are, of course, hardly more than rather detailed summaries. 



JAARllOEK VAN NEDERLANDSCH INDIE, 1916. AFDEELING 

 Nijverbeid en Handel van bet Departement van Landbouw. Nijverheid 

 en Handel, Buitenzorg, Java. [Limp clotb, 237 pages. 31 illustrations, 

 tables.] 

 This finely illustrated yearbook of the Dutch East Indies was 

 compiled by the Section for Industries and Commerce of the 

 Department of Agriculture, by order of the Dutch East Indian 

 Government, and presents a general review of the conditions 

 in these colonies as they were in the year 1914. The opening 

 chapter is devoted to a short description of the geological nature, 

 climate, population, flora and fauna of the islands. Further 

 brief and lucid chapters treat such subjects as Government and 

 Judicature, Finance and Taxation, Agriculture, Commerce, 

 Traffic and Communications. In connection with the rubber 

 industry, the number of enterprises, their distribution, the acre- 

 ages devoted to the different kinds of rubber, as well as the 

 quantities and values exported during several years, find men- 

 tion. Most of the subjects are prefixed by a short historical 

 summary. 



Although occasionally more detailed treatment would have 

 been desirable, the volume is both interesting and valuable, and 

 since it is published in English, should find a large circle of 

 readers.

These bulletins, of a series distributed by the above-named 

 company, while in the nature of a catalog, contain a great 

 amount of information as to the progress and method of un- 

 derground and submarine transmission of electricity. Descrip- 

 tion of the various forms of cables, terminology decided upon 

 by the Bureau of Standards, tables giving resistance, induct- 

 ance, reactance, impedance, maximum voltages of cables, cords 

 and fle.xibles are given, and added to this are descriptions of 

 coupling boxes, cable bells, junction boxes, manhole boxes. 



NEW TRADE PUBLICATIONS. 



~PHE Federal Rubber Co., Cudahy, Wisconsin, has published a 

 *■ little booklet entitled "Care Saves Wear," which treats of tlie 

 care of tires. Photographs of damaged tires are shown and full 

 explanations given of the causes of injury, with suggestions for 

 prevention. Motorists can read this book w-ith interest and profit.

Users of trucks — and what progressive manufacturing firms to- 

 day are not? — will find interesting and informative reading in 

 two well-illustrated booklets now being mailed on request by 

 the Link-Belt Co., Chicago, Illinois. They are entitled "Link- 

 Belt Roller Chains for Tractors and Trucks" and "Some Facts 

 About Roller Chain Drives." The latter is written by a large 

 user of chain drives, the Smith Motor Truck Corporation, Chi- 

 cago, Illinois, and points out particularly the growing list of 

 government decisions in favor of chain drive which has resulted 

 from the severe tests of European warfare. Every argument 

 appeals to reason.

With the determination of the United States Government 

 to do its share in winning the war very largely through the 

 air, the .'Army and Navy Air Services have come into far greater 

 prominence than hitherto and seemed to demand a specialized 

 publication devoted to their interests. The Gardner, Moffatt 

 Co., New York City, was quick to meet this need with the "Air 

 Service Journal," a new illustrated weekly which made its first 

 appearance July 12 with the announced purpose to chronicle the 

 news of the entire aircraft industry ; to relate foreign events in 

 the air ; and to record progress and tell of personnel. Judging 

 by the character of the first issue, with its special authoritative 

 articles on military and naval aeronautics, the paper will prove 

 of value to manufacturers, officers, enlisted men and all engaged 

 in the aircraft industry or service. The subscription price is 

 $3 a year ; foreign subscription, $4.

"The Journal of the Society of Automotive Engineers," for- 

 merly the "S. A. E. Bulletin," made its appearance dated July, 

 1917, as a handsome 9 by 12 inch standard size technical paper 

 of 96 pages, with 78 . additional pages of advertising. Hence- 

 forth its attractive appearance, varied contents and authoritative 

 character bespeak for it a prominent place among Ameri- 

 can engineering journals. The first issue is devoted chiefly to 

 the papers and reports read at the semi-annual meeting of the 

 S. A. E. held June 26 at the Bureau of Standards, Washington, 

 D. C, and indicate the vast amount of constructive assistance 

 being rendered the government in perfecting and standardiz- 

 ing automotive construction of every type for war purposes. 

 Many illustrations, diagrams and portraits embellish the text. 

 The publication is issued monthly from the offices of the society, 

 29 West Thirty-ninth street. New York City, subscription price, 

 S5 a year ; to members, $2.50 a year.

No one who has read H. S. Firestone's article, "Three Im- 

 portant Lessons My Business Has Taught Me," in "System" for 

 July, will marvel at the success of the Firestone Tire & Rubber 

 Co.. with its assets of over $33,000,000. surplus of $18,000,000 and 

 1917 business estimated at $60,000,000. Such principles of in- 

 tegrity, sound judgment and determination are bound to win. 

 While pointing out fundamentals, Mr. Firestone claims to know 

 of no absolute formula for success. "Simmered down," he writes, 

 "business success depends chiefly upon the man and his adapta- 

 bility and willingness in balancing his own factors of strength 

 and weakness, and appraising and balancing the corresponding, 

 factors in others."
