THIS work is the tenth volume in a series known as "New 

 Handbooks of Chemical Technologj-" under the editorship 

 of Dr. C. Engler, of Karlsruhe. 



The author in his preface states that his object is to supply 

 the technical man with knowledge of the scientific aspects of 

 the rubber industry and the fundamental principles of rubber 

 manufacture, as applied in typical classes of goods. He has also 

 endeavored to aid practical rubber men to correlate their per- 

 sonal experience and observation by a comprehensive treatment 

 of the industry. 



Xo attempt is made to explain the details of manufacture, nor 

 is the question of manufacturing costs treated. The aid of able 

 specialists has been enlisted in the preparation of certain chapters, 

 and thus the value of the discussion of various important topics 

 is enhanced. 



The book follows a natural order of arrangement, beginning 

 with historical matter and the chemistry of pure rubber. The 

 work is divided into two parts, general technology and special 

 technology of rubber goods. 



In the first section the origin, gathering, washing and drying of 

 crude rubber are treated, together with a chapter on resins and 

 albumens. Tests of crude rubber are given, and the subjects 

 of mastication, fillers, mixing and calendering are considered. 

 Under chemistry and methods of vulcanization is a resume of 

 the work of the leading chemical investigators of this phase of 

 rubber manufacturing. The technical operations of vulcanization, 

 hot and cold, methods of analysis, tests and apparatus for chem- 

 ical and physical examination of vulcanized rubber are also 

 given careful attention. The chapters devoted to the tests for 

 crude rubber, and on analysis and testing, are written by Dr. 

 E. Kinscher. 



In the second section of the book, which is devoted to the 

 special technology of rubber manufacturing, two chapters are 

 devoted to cold cured goods and seven to hot cured. Under 

 cold cured goods, the chapter on cut sheet is written by E. 

 Herbst, of Vienna, and includes governmental regulations on 

 the plan and equipment of cold cure plants. The author of the 

 volume wrote the chapter that follows on seamless rubber goods, 

 which treats of solvents, dipping, etc. 



Under hot cured goods the subject of mechanicals is treated 

 by Mr. Herbst and the author, who review the applications 

 of rubber and discuss the proper arrangement of rubber factory 

 workrooms. K. Miksch, of Petrograd, contributes a chapter on 

 rubber heels and rubberized fabric in which the various processes 

 of manufacture are described. Rubber toys are discussed by Dr. 

 Dorogi, of Budapest, who tells of the principles of manufactur- 

 ing and finishing these products. Two chapters by Mr. Herbst 

 are devoted to all types of solid and pneumatic tires and anti- 

 skid devices, and to the manufacture of rubber footwear. The 

 final chapter is on hard rubber, and is prepared by Engineer 

 Ballog and the author. 



TRANSACTIONS OF THE RUBBER GROWERS' ASSOCIATION. 

 1915, London, England. The Rubber Growers' Association. [Paper 41 

 pages.] 

 This is the seventh report of the Council. It comprises lists 

 of the officers, committees, the members and the representatives of 

 the Association on committees of the Rubber Trade Association 

 of London; also officers and committees of the International 

 Association for Rubber Cultivation in the Netherland Indies. 

 The membership of the Rubber Growers' Association has rapidly 

 increased since organization in 1908: it now includes 412 com- 

 pany and 250 individual members. During the past year (1915) 



the activities of the .Association have expanded with the impor- 

 tance of the rubber growing industry and in consequence reor- 

 ganization of the Association has been necessitated. 



The administration of the Malay and Ceylon Research Funds 

 has been assumed. The work of these funds has greatly bene- 

 fited the plantation rubber industry by chemical and botanical 

 research. The work of each of the association committees is 

 detailed in the body of the report. Record is made of many gifts 

 made through the Association to the British War Department, 

 of much equipment such as an ambulance, 4000 life saving col- 

 lars for the Australian navy, rubber boots to the Royal Flying 

 Corps, cushions and pads and rubber flooring to various hospi- 

 tals. 



AGRICULTURAL BULLETIN OF THE FEnERATED MALAY 

 States. Department of Agriculture F. M. S. Kuala Lampur. 1915. 

 [Monthly parts 50 cents each. Annual subscription $5.00.] 



This publication is the organ of the above mentioned depart- 

 ment and of the Planters' Association of Malaya. In it is pub- 

 lished a wide variety of scientific and statistical reports relating 

 to tropical agricultural interests, notably rubber and other im- 

 portant plantation products. The papers record the laboratory 

 and field investigations of the large scientific staff of the Fed- 

 erated Malay States department of agriculture. 



Notable among the published papers of the past year is the 

 series by B. J. Eaton and J. Grantham entitled "Vulcanization 

 Experiments on Plantation Rubber." an important study of the 

 influences affecting the standardization of plantation Hei'ca as 

 regards curing quality and physical characteristics after vul- 

 canization. 



STUBBS' BUYERS' DIRECTORY FOR THE WHOLESALE DRUG. 

 Chemical and Allied Trades. 1916. .Mfred Stubbs, 30 Cliff street. New 

 York City. 1916. [8vo, 350 pages. Price, $3.00.] 



The revised and enlarged edition of this trade directory is 

 a valuable reference book for the purchaser of drugs and chemi- 

 cals. It comprises two sections, both arranged alphabetically by 

 materials. The first section contains a list of manufacturers and 

 first-hand dealers in drugs, chemicals, essential oils, laboratory 

 machinery, etc.; and the second a similar list relating to drug- 

 gists' sundries, glassware, etc. 



Many of the articles listed are of interest to the rubber chemist 

 and compounder who will find the directory of practical value 

 in locating sources of supply. 



DICTIONARY OF TEXTILES. BY LOUIS HARMUTH. FAIRCHILD 

 "Tew York City. 1915. [Cloth. 8vo, 174 pages. 



Pric 



$5.; 



This dictionary, the result of over seven years of collecting 

 and compiling, contains the definitions of over 6,600 terms relat- 

 ing to textile fibers and fabrics. These are arranged in alpha- 

 betical order, each term being discussed independently. While 

 essentially designed for those engaged in the textile industry, 

 rubber manufacturers will find- it a helpful reference. 



PHEDICTS 200,000 TONS OF HEVEA RUBBER IN 1919. 



Basing the average production of Hcvca rubber at 400 pounds 

 per acre, it was estimated at a meeting of rubber planters held 

 in Bandong, Java, that the world's production of Hcvca rubber 

 in 1919 would amount to 200,000 tons. 



A RUBBER BRAKE FOR ROLLER SKATES. 



One of the latest safety devices in which rubber is employed 

 is a guard for roller skates, to prevent the skater from tipping 

 backward. This is in the form of a steel, rubber-tipped apron, 

 which extends from the top of the heel or counter of the skate 

 to within a very short distance of the floor. Should the skate 

 suddenly attempt to fly out in front of the wearer, the rubber 

 tip comes in contact with the floor and prevents a bad fall.
