MARINE REVIEW. | II INTERNATIONAL ENGINEERING CONGRESS. Assemblage of engineers from all parts of the world--A full report of the several sessions of the branch devoted to marine and naval engineering and naval architecture. Nearly every civilized nation was represented at the Inter- national Engineering Congress held at the Art Palace on the lake front in Chicago last week, and the assemblage of engineers, which has been looked to for some time past as one of the features of the World's Columbian Exposition, was truly the greatest ever witnessed in the world. As readers of the REVIEW are most interested in the proceedings of the division: of marine and naval engineering and naval architecture, this account will be confined to the proceedings in that division, although it will be necessary to refer briefly to the opening general session of all the divisions. The Hon. C. C. Bonney, president of the World's Congress Auxiliary, delivered an address of welcome, which was echoed by Mr. Octave Chanute, first vice chairman of the general com- mittee of the International Engineering Congress. Addresses were also made by Sir Benjamin Baker of England, builder of the Forth bridge, Baron Quinette de Rochemont of France, C. O. Gleim of Germany, and several other distinguished foreigners, and also by the chairmen of the. different divisions of the con- gress, namely: Mr. William Metcalf, division A, civil engineer- ing; Mr. Eckley B. Coxe, division B, mechanical engineering ; E. G. Spilsbury, division C, mining engineering; Henry M. Howe, division D, metallurgical engineering; Prof. Ira O. Baker, division EK, engineering education; Major Clifton Comly, U. S. A., division F, military engineering, and Commodore Geo. W. Melville, U. S. N., division G, marine and naval engineering and naval architecture. The general meeting then adjourned and the seven divisions of the congress opened sessions imme- diately afterward in the various halls. MARINE AND NAVAL ENGINEERING AND NAVAL ARCHITECTURE. About forty-five papers from the most distinguished repre- sentatives of the ship building industry in Great Britain, France, Germany, Spain, Italy and the United States were contributed to the division of marine and naval engineering and naval archi- tecture, and thirty-three of them were in print, while less than half a dozen of the whole number of papers put down on the programme failed of appearance. The foreign attendance was more than equal to that in other branches, and was fully up to what was expected in consideration of the diversified interests represented in the general congiess.

The first session began with an address by Commodore Melville, in which he expressed gratification at the large attend- ance, and welcomed the.foreign guests. _ He then gave a brief summary of the present condition of matters connected with marine engineering and naval architecture, and sketched briefly the lines along which future progress will probably be made, calling special attention to the fact that it will most likely be on about the same lines as in the past, which have consisted of an increase of steam pressure, an increase of piston speed, better material and, possibly, changes in design to a certain extent. He mentioned that experiments are now being made with steam of 1,200 pounds pressure, and called attention to the possibili- ties of the coil boiler for enabling great power to be obtained with little weight. He also mentioned in the course of his remarks the death of Dr. Alexander C. Kirk, a member of the advisory council of the division, who had begun a paper on the triple expansion engine, and on which he was engaged at the time of his death. The first paper was by Sir Nathaniel Barnaby of England on "The Best Ship of War." 'This was a paper worthy of its eminent author and in brief compass contained the results of the experience of that eminent architect. This paper was dis- cussed by Dr. Francis Elgar of England, Chief Engineer Kafer, _of the U. S. N., Professor Durand of Cornell University, Naval Constructor Varney, U. S. N., and several others. Other papers were by Mr. Lewis Nixon, superintending architect of Wm. Cramp & Sons Ship and Engine Building Company of. Philadelphia on " The New Vessels of the United States Navy,"' and " Naval Architecture in the United States"? by Benjamin
