SECOND EXPOSITION OF CHEMICAL INDUSTRIES
The Seeond Exposition of National Chemical Industries took place September asth t o 30th. occupying two floors in the Grand Central Palace, New York City. At the opening meeting Mr. Charles F. Roth, one of the very efficient managers responsible for the organization of the exposition, introduced the speakers. Dr. Charles H. Herty. President of the American Chemical Society, explained that it had been the fixed determination of the managers and advisors of the exposition t o make the chemical show a place for earnest men of the country to bring together their products, not for the purpose of boasting, hut t o demonstrate their ability to meet the situation and thus t o afford inspiration for the future, I n other words, the exposition was planned to be not only B showing of what had heen accomplished, but also the assembling of resources of the nation concerning which expert representative men of the various industries could consult and give and obtain expert advice. Such displays will undoubtedly bring about cooperation of state govern-

industrial world, for the latest census of manufactures shows that in America the manufacture of paper is second in importance only t o the steel industry. The total invested capital is estimated a t $ s o o , o o o , ~ ,in round numbers, while the annual value of the manufactured product-pulp and paper-amounts t o $350,000,000.“ Dr. Ira Remsen, formerly president of Johns Hopkins University, was enthusiastically received by ‘the audience, and expressed his desire t o have it thoroughly understood that he had always been interested in chemical industry i s spite of the numerous statements that had heen made to the contrary. The truth of the matter was that his contributions t o chemistry had heen a t the other end of the line, since i t had always been his belief that industry grows only when science grows. Mr. Adriaan Nagelvoort, comanager of the exposition with Mr. Roth, called attention t o the fact that the industrial developments of t h e last year were possible only in such a country as America, a notable instance being the fact that the dyestuff firms of the country are now making 75 per cent of the quantity needed in 1913. The audience was then invited t o visit the various exhibits of the “Second Chemical Show,” Uuusually attractive features of the exposition were the moving pictures, shown every afternoon and evening, illustrating the p r m s of manufacturing a wide range of products. Acknowledgment WBS made to the Bureau of Commercial Economics for their collaboration in this program. These pictures included the following: Manufacture of Iron *ad Steel Tubing Black Powder. Futilizem Iron. Silk. Blotting Paper, Vpmish, Sdvcr Miding. Asphalt (Barber Arphnli

merits. railroads and national government by setting forth how the resources of the nation may be best put under chemical direction, for the primary responsibility for the development of these resources rests chiefly upon the chemists of the country; that the necessity of Such maperation is required by other nations is indicated by the recent unification of the dyestuff industries of Germany and the chemical conference of the allies. during which they agreed t o interchange technical knowledge in place of continuing individualistic efforts as heretofore. Dr. Lawrence Addicks, President of the American Electrochemical Society, called attention t o the development of the electrochemical industries from the modest beginning of electric batteries to manufacturing processes that require the highest type of chemical engineering. Electrochemistry has the peculiar character of forming the meeting place for electro chemists. physicists, metallurgists and physicians, thus helping to break down the harriers betweeu so-called pure science and engineering. The high prices of the present time are constantly bringing about fields of new uses for materials and especially the lower grade materials which must necessarily replace the shortage of the higher priced ones. In the great awakening that has brought about coordination of industrial rewurces for national defense, Dr. Addicks considers the accomplishments up t o the present as merely an earnest of what is t o come. Mr. Thomas J. Keenan. Secretary of the Technical Association of the Pulp and Pawr Industry and Editor of Paper. spoke in place of President Daniels of the American Paper and Pulp Awxiatian. “The papermaker stands next to the highest place in the
