RUBBER CLUB NEWS. 



The Rubber Club of America is a member of the Chamber 

 of Commerce of the United States of .■\tnerica, of Washington, 

 D. C, and was recently asked to vote on certain recommenda- 

 tions which tlie latter body contemplates suljmitting to Congress. 

 The first recommendation called for the creation by Congress of 

 an Interstate Trade Commission, but the Rubber Club, after a 

 thorough canvass of its firm members, has decided to oppose 

 this recommendation and has registered a negative vote with the 

 Chamber of Commerce. 



At the meeting of the Fxecutive Committee held May 19, 1914, 

 Francis H. ,\ppleton, Jr., was appointed chairman of the Sports 

 Committee in place of W. L. Pitcher. Mr. Pitcher declined to 

 serve, on the ground that the chairman sliould be someone located 

 in Boston. 



Capt. Francis 11. .Appletnn was appointed chairman of the 

 Committee on Resolutions in place of E. E. Wadbrook who 

 declined to serve. 



Henry Spadone, of the Gutta Percha & Rubber Manufacturing 

 Co., was added to the Nominating Committee in place of E. E. 

 Wadbrook wlio declined to serve. 



A special committee to decide the date and place of the outing 

 of the club the coming summer was appointed as follows : Fred- 

 erick H. Jones, of the Tyer Rubber Co., Andover, Massachusetts ; 

 Robert L. Rice, Hood Rubber Co., Watertown, Massachusetts, 

 and Harold P. Fuller, of the E. H. Clapp Rubber Co., Boston. 



George B. Hodgman and Harry S. Vorhis were appointed as 

 delegates of the Rubber Club of .\merica to the Chamber of 

 Commerce of the United States of .■\merica. George B. Hodg- 

 man was appointed a member of the National Council of this 

 Chamber. 



F. H. Sanfiird. formerly mana.gcr of tlie lirm of .\delbert H. 

 Alden, Limited, of Manaos, Brazil, is now living in the south 

 of France, having retired from the ruliber business with a com- 

 petence. 



SOLVENTS, OILS, GUMS, W.'VXES AND ALLIKIJ SUBSTANCES. 

 By Frederic S. Hyde. Ph.B., New York, 1913. D. Van Nostrand Co. 

 [Clolh, 8vo, 176 pages. Price, $2.00.] 



IN this condensation of the main facts reluting to the coni- 

 * mercial organic products associated with industrial chem- 

 istry, Mr. Hyde has placed a valuable book of reference at the 

 disposal of factory chemists and others interested in technical 

 investigations. 



Besides the subjects referred to in tlie titU-. there arc various 

 others dealt with, bringing the number of chapters to fifteen. 

 Under the licad of "X'arious Solvents and F'luids" prominence 

 is given to aldehydes, alcohols, ethers and l)enzcil derivatives, 

 attention being drawn to the distinction between the last-named 

 substance (or b-e-n-z-e-n-e) and petrolic benzine, or refined 

 naphtha. The following chapter is devoted to terpene bodies, 

 camphors, essential oils, fragrant substances and balsams. 



In the third chapter the differences are pointed out between 

 true gums and gum resins, which do not come under the former 

 category. .\t this point the rublier chemist will find interest in 

 the chemical description of rubber, recalling certain known 

 facts such as the specific gravity of pure rubber being less than 

 that of water. The commercial product in balls or cakes, it is 

 added, is generally gray or brown from oxidation and impuri- 

 ties, being more or less elastic and liable to have a sour, un- 

 pleasant odor. It is insoluble in alcohol, and unaffected by 

 dilute acids or alkalies. 



Manufactured rublier may, however, be rendered soluble by 

 treatment with: (1) Acetone, to remove resins, oils, etc.; (2) 

 alcoholic potash, to remove oxidized fatty "substitutes"; (3) 

 cold nitro-benzol, to remove asphalt or pitch ; (4) boiling nitro- 

 licnzol for solution, leaving a residue of mineral matter. Aniliii 

 at from 140 degs. to 180 degs. C. has also been proposed as a 

 solvent, the rubber being separated as a tough mass. In the 

 author's opinion hot or boiling nitro-lienzol is one of the best 

 rubber solvents, altho the material in solution may thereby 

 become partially blackened or carbonized. Pure rubber freshly 

 cut loses its elasticity on heating, and becomes brittle on chilling. 

 Vulcanizing increases elasticity and insolubility, but lessens dura- 

 bility and adhesiveness. Hard rubber contains an excess of 

 sulphur and "filler," baked at ISO degs. C. 



Gutta percha is closely related to caoutchouc, but is from the 

 latex of a different tree, being less elastic and harder than 

 rubber. Rubber substitutes are made from corn oil, linseed oil 

 and similar vegetalile oils by the action of sulphur or sulphur 

 chloride, the latter producing a' light, spongy mass somewhat 

 elastic, but friable and lacking in resiliency. .Another group 

 considered is that of bitumens. 



Carbohydrates, albumenoids and proteids are next taken up. 

 followed by a discussion of the commercial tests on oils and 

 fats. The final chapters deal with waxes and miscellaneous or- 

 ganic substances. .A full index facilitates reference, and en- 

 hances the value of this useful work. 



VANDEGRIFT'S DIGEST OF UNITED STATES TARIFF ACT, 1913. 

 F. B. Vandegrift & Co.. 15-25 Whitehall street. New York. [Paper, 

 182 pages. Price, 50 cents.] 



"T^O those seeking for light on points connected with the 

 ■'■ tariff of 1913, this handy little work affords a quantity of 

 needed information. In the first place the act itself, with its 

 fourteen schedules and the free list, occupies some 60 pages, 

 forming the first section. Section II. covering 21 pages, con- 

 tains the i)rovisions of the income tax legislation, while in Sec- 

 tions 1 1 1 and IV various administrative features are treated. 

 The text concludes with an extract of the sections of the act 

 of 1909 not repealed by that of 1913. .\n alphabetical schedule 

 of the duties, witli references to the respective paragraphs, com- 

 pletes the work, which will be appreciated by all interested in 

 the import trade.
