TURPENTINE AND THE RUBBER INDUSTRY. 



""TO THE Editor of The Indi.\ Rubber World: The forest 

 •^ service of the United States department of agriculture 

 is undertaking certain lines of work in the South with the 

 object of standardizing and grading the products of the tur- 

 pentine industry. In connection with this investigation it 

 is desired to establish a complete list of manufacturing con- 

 cerns that use turpentine in large quantities. Statements art- 

 found to the effect that turpentine is much used in the caout- 

 chouc industries; also that yellow pine oil is employed as r; 

 solvent. The information, however, is not definite. The 

 service would appreciate any data on this subject which 

 you may be willing to place at its disposal. Very truly yours, 



R. S. KELLOGG, Chief. 

 Washington, June 6, 1908. 



[Very little turpentine is used to-day in the rubber indus- 

 try. A few barrels a year may be used in certain varnishes, 

 but the amount is so small as to be hardly worth looking up. 

 The same is true of yellow pine oil. In the early days of 

 the rubber manufacture, before the discovery of vulcaniza- 

 tion, turpentine was very largely used as a solvent of rub- 

 ber. To-day the solvent largely used is naphtha. — The 

 Editor.] 



RUBBER FOR ARMY BALLOONS. 



""pHE United States army signal service recently called for bids 

 ■*■ for the construction of two balloons for army use, one ta 

 have a capacity o 1,000 cubic meters [=;35.3i6 cubic feet] and the 

 other 540 cubic meters [=: 19.070 cubic feet]. A letter 

 to The India Rubber World from the chief signal officer says: 

 "The specifications provide that the material for the gas bags 

 will be made of a fabric of American manufacture, made by 

 rolling together two layers of silk having a layer of rubber be- 

 tween. No specification for this material has been prepared. It 

 is manufactured in a great variety of forms in Europe, but in tlie 

 United States it is a new industry. This office has been in- 

 formed that some rubber manufacturers in the United States have 

 made satisfactory samples, and other manufacturers are interested 

 in the subject if there is prospect of a market. It is with a 

 view of developing this industry in the United States that the 

 specifications for balloons calls for material made in the United 

 States." 



RUBBER FOR AIRSHIPS. 



According to descriptions to hand of the "Republique," the 

 successor to the lost French airship, "La Patrie," the new ship 

 will measure 231 feet in length and 45 in width. The capacious 

 measurement will be covered with a "skin" made of thin, but ex- 

 ceedingly strong, yellowish cloth, covered with a preparation of 

 caoutchouc. However thinly, therefore, the caoutchouc or rub- 

 ber coating be laid on, the quantity used must be considerable, 

 and, should the use of airships increase, the demand for rubber 



THE LATE MONROE SEIBERLING. 



Monroe Seiberling. 



rj'QR various reasons the name of Monroe Seiberling will pass 



down into the manufacturing history of the central West 



as a leader, and in some ways the leader, aside from his 



considerable rubber interests. After living 28 years on the 



farm upon which 

 he was born in 

 Summit county, 

 Ohio, he went to 

 .-Vkron, where he 

 engaged in the 

 manufacture o f 

 flour, strawboard, 

 and other commo- 

 dities. He had the 

 perception to sfee 

 correctly the ad- 

 vantages of new 

 and untried fields 

 of manufacture. At 

 the beginning of 

 the use of natural 

 gas in Indiana he 

 was the first to 

 take advantage of 

 its utility, and 

 built plate and 

 window g 1 a s j 

 works at Kokomo 

 and other places in 

 that state, all of which were large, for Monroe Seiberling al- 

 ways had a decided aversion to anything on a small scale. After 

 the celebrated McKinley tariff bill was passed he was the first, 

 or one of the first, to build a tin plate mill, from the ground up, 

 in the United States, and operated it successfully. 



It was owing to his foresight and determination to take the 

 initiative that he started a number of his manufacturing enter- 

 prises, notably the Indiana Rubber and Insulated Wire Co., at 

 Jonesboro', Indiana, which has been in successful operation from 

 the start, many years ago. In 1896 he organized and started the 

 Peoria Rubber and Manufacturing Co.. of Peoria. Illinois, of 

 w-hich he was president and general manager, and surprised 

 everyone who knew him by the marked success he made of his 

 "Peoria" tire, during 1896 and 1897 — a line of business of which 

 no one credited him with knowing anything. The Peoria plant 

 was situated a mile from the nearest street car line, but a small 

 affair like that did not bother Mr. Seiberling, and he promptly 

 built the shortest steam railroad in the United States. He cer- 

 tainly believed in the old saying that difficulties were only made 

 to be overcome and he was unique in the task of overcoming 

 them. 



Mr. Seiberling died February 25, 1908, at his home in Oak 

 Park, Illinois, at the age of 6g. He is survived by eight sons 

 and daughters — Mrs. Charles J. Butler, of Detroit, Michi,gan, 

 whose husband is president of Morgan & Wright ; Mrs. F. L. 

 Kryder, Akron, Ohio ; Ella S. and Grace Seiberling, Oak Park, 

 Illinois ; and the sons, Alton Grant, Kokomo, Indiana ; Fred A., 

 Oak Park, Illinois; Laird H., Marion, Indiana, and George W., 

 Detroit, Michigan. 



HKirisH Columbia newspapers rcpi'rt the successful issue of a 

 suit brought by the Dunlop Tire and Rubber Goods Co., Limited 

 (Toronto), against certain parties in that province who were al- 

 leged to have infringed the Dunlop patent on pneumatic bicycle 

 tires.
