shoes and the brands used upon them is so arranged that the 

 "Champion" tennis cut-out boy can be so hung as to swing in 

 this frame, balanced by his legs extending forward under the 

 frame, the feet showing white tennis shoes with the "Champion" 

 trade-mark upon them. The boy is an amusing little fellow who 

 swings back and forth at every pufY of wind and thereby makes 

 an effective advertisement for this line of footwear, if hung in 

 a window or suspended in a store. Another cut-out simulates 

 the United States Rubber Co.'s patent pressure process "Storm 

 King" boot, which is represented standing upon a box appropri- 

 ately labeled and having at one end the newly adopted trade- 

 mark of the company. The boot is in bright red and also shows 

 the trade-mark on the front of the leg. 



The Hyde Manufacturing Co.. manufacturers of specialties in 

 knives and cutting tools, Southbridge, Massachusetts, has issued 

 Catalog R. this being devoted entirely to knives for rubber 

 workers. One would hardly suppose so great a variety and 

 number of different cutting tools are required in the rubber in- 

 dustry. In the thirty or more pages are pictured, described and 

 priced several hundred knives, with points of every conceivable 

 shape for the hand worker, square, half round, round bevel and 

 taper point, tire knives, lathe knives, circular and machine knives. 

 The catalog is excellently arranged and should find a place in 

 every rul'ber factory. 



The Peerless Rubber Manufacturing Co., New York City, 

 sends out its catalogs in specially folded stiff paper covers, which 

 allow a new page to be inserted where changes need to be made 

 in the lists. Two of these catalogs relate to belting and packing, 

 and both are handsome specimens of typography, each page being 

 printed in two colors, the goods pictured in excellent half-tones 

 and the description thorough in all respects. The belting book- 

 let gives a considerable amount of information regarding the 

 application of belting, horse power rules, pulley diameters, belt 

 capacity, etc. Both books are likely to prove useful to the many 

 customers of this concern. 



"The Romance of Rubber" is the title of a little 24-page book- 

 let published by The B. F. Goodrich Co., Akron, Ohio, to exploit 

 its products. The plan of the book is to show at the top of each 

 page a fine half-tone picture relative to the gathering or manu- 

 facture of rubber, while at the lower outside corner of each page 

 is an appropriate picture of sometliing relative to the gathering 

 of rubber, or scenery in tropical countries. The text is informa- 

 tive, though it contains practically little that is not known to 

 every rubber manufacturer and to most people in the rubber 

 trade. In typography it is up to the high standard of the pul)- 

 lications emanating from this enterprising company. 



The United States Tire Co., New York City, has recently pub- 

 lished a small vest pocket brochure that will interest the motorist 

 who really wants to know the facts about individualized tires. 

 The title is "Judging Tires." and it treats very pertinent ques- 

 tions, such as "Which type of tire will last longest on your 

 weight of car." "Which type of tire will last longest under your 

 road conditions," and other factors to be considered in the se- 

 lection of tires. 



The business of repairing pneumatic tires has become an im- 

 portant one and any measure which will advance the ability of 

 repairers is one which will be truly welcome. The Goodyear 

 Tire & Rubber Co., Akron, Ohio, has published a "Manual 

 of Tire Repairing" which gives in condensed form, in a book 

 of less than 50 pages, directions for repairing every sort of tire 

 injury, — cuts and punctures, breaks in fabrics, blow-outs, rim 

 cuts, as well as splicing inner tubes, relining and retreading, 

 vulcanizing, etc. There are given besides this a form of tag 

 and return check for repairers, a system of accounting, and a 



large number of illustrations showing the tools and machines 

 necessary for the up-to-date repair business. 



The Underwriters' Laboratories, Chicago, Illinois, whose work 

 in connection with testing materials and appliances used in 

 the prevention and suppression of fires is well known, has sent 

 to all holders of its June, 1915, edition of "Standards for Rubber 

 Covered Wires and Cables," 12 revised pages to take the place 

 of the same number of pages in that edition. On account of 

 the arrangement of the original edition these new pages can 

 readily be inserted in their proper places and thereby render the 

 book up to date. Most of the changes are explanatory, but some 

 show changes of more or less importance. AM changes are printed 

 in italics and therefore can be easily and quickly distinguished.

The Institution of Electrical Engineers, London, England, has 

 sent The India Rubber World a copy of "Wiring Rules" issued 

 by that institution, with extracts from Board of Trade and 

 Home Office regulations for factories and workshops. This, as 

 its name indicates, is a compilation in compact form of all the 

 rules which are required by the British Government as regards 

 wiring factories, workshops, mines, theaters and private houses. 

 It tells what is required for insulation, classing vulcanized rub- 

 ber insulation as Class A, while hygroscopic dielectric insulation 

 such as impregnated paper or fiber is in Class B. The pamphlet 

 also gives the thickness of rubber insulation required, and much 

 practical matter of interest to those having charge of installing 

 electricity. Among other changes in this edition may be men- 

 tioned provisions made for conductors with hard-rubber-com- 

 pound protection. 



REGISTRATION OF THADE-MARKS IN LATIN AMERICA. 



The American exporter or manufacturer selling goods in 

 Latin America should protect his trade-marks. Attention 

 should be called to the difference in the legal point of view 

 as to the ownership of trade-marks between the Latin American 

 countries and the United States. By the common law, use is the 

 basis of property in a trade-mark, and registration in the L'nited 

 States is merely an additional means of protecting that property 

 right acquired by use. In the Latin American countries, on the 

 other hand, the rights of property in a trade-mark are derived 

 entirely from the law and depend on the registration of the mark. 

 Registration is usually granted without investigation of the right 

 to its use, though after due notice to those interested by publica- 

 tion of the application in the official gazettes. When once ef- 

 fected, registration is final against all later comers. The im- 

 portance of registration is therefore greater in the Latin 

 American countries than in the United States, in view of the 

 possibilities for unfair registration under the trade-mark laws 

 in i-tYect in those countries. 



MAKING DIVING CAPS. 



The diving cap is a quiet and unassuming affair compared to 

 the ornate modern bathing cap. of which it is the prototype. 

 Utilit.w rather than beauty, is aimed at in its design, but w^hat 

 it lacks in appearance it 

 amply repays in efficiency, 

 as every swimmer knows. 

 These are always made 

 entirely by hand. The two 

 pieces forming the cap are 

 cut from a sheet of raw 

 unvulcanized stock and the 

 cemented seams united by 

 a hand stitcher on the 

 seaming form shown on 

 Ik- left. This form is hinged and provided with a short locking 

 rm. When tliis is released the form collapses, as shown on the 

 ight. and the cap is removed and vulcanized.
