out of practice, as on the cruise the admirals did all the speak- 

 ing. He then emphasized the value of the cruise on other 

 countries; for example, on Central American states that had in 

 the past believed that the United States had but a few cruisers 

 and those of an obsolete type. He said that the ability to use 

 the strong arm of force was the best sort of peace insurance. 

 After mentioning the wonderful receptions given to the fleet in 

 Yokohama and in Sidney, he told of shore experiences in Col- 

 ombo and of the special train that took the visiting officers up to 

 Kandy, where they were most bountifully entertained. 

 Professor Hovg.xard. 

 The next speaker was then thus introduced : 



Naval architecture to-day calls for exceptional learning, the highest type 

 of constructive ability, and thorough knowledge of seamanship. When our 

 esteemed neighbor, the Hon. John D. Long, was secretary of the navy, he 

 recommended as professor of naval design for the Massachusetts Institute 

 of Technology, the leading authority in that line in the world. Professor 

 William Hovgaard of Norway, whom I now introduce. 



Professor Hovgaard briefly and in a scholarly way sketched 

 the evolution of the American navy from the time of the wooden 

 ship up to 1890, when we were equipped to build our own steel 

 ships. He described the American invention, Harveyized steel 

 armor, which added 25 per cent, to the strength of armor plates. 

 He described the effect of the Spanish-American war on the 

 American navy and the effect of the Russo-Japanese war in naval 

 construction. He paid a high tribute to the versatility, not only 

 of the commanders, but of the petty officers who were trained 

 to know every particular of the great fighting machines on which 

 they were stationed. 



A telegram was received just before the dinner from one whom 

 the whole club had hoped to hear, Captain Felix H. Hunicke, a 

 veteran of the Spanish-American war, and to-day a member of 

 the rubber trade. Serious illness in his family had prevented 

 the captain from coming to Boston, much to the regret of those 

 present. 



TIRES AT BOSTON AUTO SHOW. 



NEPONSET SPLICING COMPOUND. 



THE requisites of a first class splicing compound are perma- 

 nently high mechanical strength, adhesiveness and dielectric 

 strength, ease of manipulation and long life. It is claimed that 

 these qualities are possessed in preeminent degree by the "Nepon- 

 set" splicing compound. It is furnished in two standard thick- 

 nesses of .035 and .048 inch, on glazed muslin in one-half pound 

 rolls, %-inch wide. It will stand a tensile stress of 500 pounds 

 per square inch of cress section area, so that in winding it 

 around a conductor or wire joint the manipulator may stretch it 

 as strongly as may be necessary to make a tight, snug covering, 

 without risk of breaking it from the pull. 



In addition to these properties it has the further features of 

 excellence that no heat is required in its application. It thus 

 combines ease of manipulation with the best electrical and 

 mechanical qualities. 



The adhesiveness of this compound thus is so great that mod- 

 erate tension in winding the tape over a joint or conductor 

 causes each successive overlapping layer to become an integral 

 part of the whole, making a thoroughly watertight as .well as 

 waterproof envelope. 



Its dielectric strength is high. A single thickness of the .03s 

 inch tape will successfully withstand a puncture test of 10,000 

 volts. This renders it especially valuable and safe to use in high- 

 tension transformers, joints on transmission lines, and in station 

 wiring, and in all places where the circuits are liable to be sub- 

 jected to high-potential strains due to lightning, surges on the 

 line, and the like. Manufactured by the Massachusetts Chemical 

 Co. (Wapole, Mass.). 



A NEW edition of Mr. Pearson's "Crude Rubber and Com- 

 pounding Ingredients" is now in press. 



'T'HE seventh annual show conducted by the Boston .Xuto- 

 mobile Dealers' Association, under the management of Mr. 

 Chester I. Cam.pbell, was held this year as usual in Mechanics' 

 Building, on March 6-13. Before this series of shows began 

 there were automobile exhibitions in Boston, beginning with 1898, 

 when automobiles were displayed as a feature of the Mechanics' 

 Fair. The Boston show has become one of the yearly automobile 

 exhibitions of national importance, and the one held this year 

 excelled those of former years in extent and in the popular 

 mtercst displayed. There were shown altogether 335 machines, 



including chassis, in 

 additidn to 68 motor- 

 cycles and 6 bicycles, 

 which indicates that 

 a large number of 

 makers were repre- 

 sented. It is to the 

 Boston show that 

 most of New England 

 looks for the latest 

 ideas in automobiles, 

 and many sales result 

 from it. The same 

 applies to tires and 

 other accessories 

 which were also ex- 

 hibited in profusion 

 this year. 



While, perliaps, 

 four-fifths of the 

 lirms exhibiting at 

 Boston had exhibited 

 previously at New 

 York or Chicago, 

 Chester I. Campdell. there were new- 



[Manager of the Boston -Automobile .Show.] comers, and besides 



some of those who had been represented at earlier shows had 

 novelties to offer. In this article, however, space can be given 

 only to naming the tire and accessories exhibitors. 



Shawmut Tire Co., of Boston, of which Mr. A. N. Hood, of 

 the Hood Rubber Co., is treasurer, made their first appearance 

 at any automobile show, and report themselves very well pleased 

 with their success. Their exhibit included "Shawmut" pneu- 

 matic tires, tubes and tire accessories. They attracted attention, 

 for one reason, on account of being Boston made, and for 

 their proved claim to be made of "strong rubber and strong 

 fabric." 



The other leading tire makers were well represented, in- 

 cluding the Ajax-Grieb Rubber Co., Batavia Rubber Co., Tlie 

 B. F. Goodrich Co., Commonwealth Rubber Co., The Diamond 

 Rubber Co., Dow Tire Co., Empire Auto Tire Co., Fire- 

 stone Tire and Rubber Co., The Fisk Rubber Co., Goodyear 

 Tire and Rubber Co., G. & J. Tire Co., the Hartford 

 Rubber Works Co., Michelin Tire Co., Morgan & Wright, Penn- 

 sylvania Rubber Co., the Republic Rubber Co., Rutherford Rub- 

 ber Co., and Swinchart Clincher Tire and Rubber Co. 



Atlas Rubber Co. (Buffalo, New York) exhibited their "Non- 

 Puncture Inner Case," illustrated in The India Rubber World 

 for February i [page 178]. The Doolittle demountable quick de- 

 tachable rim, new this year, attracted considerable attention. 



Voorhees Rubber Manufacturing Co. (Jersey City, New 

 Jersey) exhibited their specialties; Leather Goods Tire Co., 

 leather tires; Zeglan Bullet Proof Cloth Co., special tire fabrics, 

 and Hopewell Brothers (Boston) a full line of tire cases. 



The attendance was good throughout the week, and there 

 was every indication that the Boston public is still interested 

 in automobile shows.
