may be able to print a special article on the subject in due time. In the meanwhile there is given above an article by Professor Turner on our present knowledge of earthquakes. There is also printed in this number of the Monthly a paper by Major Dutton suggesting a hypothesis to account for the allied phenomenon of volcanoes. Those of our readers who wish to inform themselves on the nature of earthquakes and the methods of recording and studying them should read the book on the subject by Major Dutton, recently published in the 'Science Series' by the Putnams.
THE ENGINEERING BUILDING OF NEW YORK CITY
The corner stone of the United Engineering Building in New York City, already more than half completed, was laid on May 8 by Mr. Andrew Carnegie, to whose munificence the building is due. It will be remembered that, in view of Mr. Carnegie's gift of one and one half million dollars, the United Engineering Society was incorporated on May 11, 1904, under the legislature of the state of New York for "the advancement of the engineering arts and sciences in all their branches, and to maintain a free public engineering library." The 'Founder Societies' represented in the corporation are the American Institute of Electrical Engineers, the American Institute of Mining Engineers and the American Society of Mechanical Engineers. The building of the United Society will provide permanent headquarters for these three national engineering societies and for the Engineer's Club, and also places of meeting and office room for such other engineering and scientific societies as may from time to time be admitted as 'associates.' Power to administer the trust is invested in a board of trustees of nine members, consisting of three representatives elected by each of the Pounder Societies. The expense of maintenance must be shared by the three societies participating in the foundation, in accordance with regulations imposed by the United Society. The following are the charter members of the corporation: Charles F. Scott, Bion J. Arnold and S. S. Wheeler, of the American Institute of Electrical Engineers; C. W. Hunt, F. R. Hutton and James M. Dodge, of the American Society of Mechanical Engineers; A. R. Ledoux, Charles Kirchoff and Theodore Dwight, of the American Institute of Mining Engineers.
The building of the new society is in process of erection on the north side of thirty-ninth street, between Fifth and Sixth Avenues, the site covering five city lots with a total front of 125 feet and a depth of 100 feet. The new building utilizes only 115 feet of the front and as it controls the other side, space is left on all sides of the granite pile of thirteen stories, which thus presents an imposing monumental appearance. The plans are entrusted to Messrs. Hall and Rogers, and Henry Gr. Morse, associate architects, for the three engineering societies and Messrs. Whitheld and King for the Engineering Club. The building, as shown in the illustration, is a notably worthy product of the modern science and art of building construction that may well serve to typify the purposes for which it was conceived.
Primarily it must serve the convenience of the individual societies which enter it as founders. To this end a floor provides adequate rooms for each of the societies, as shown in the case of the electrical engineers in the accompanying plan. In addition meeting rooms and auditoriums are to be furnished for the regular and special meetings of the societies and for scientific lectures and demonstrations. Other assembly rooms have been specially adapted to suit the various uses for which they may be required.
There is one large auditorium with accommodations for 1,000 persons, on the first floor above the street. The foyer and corridors afford ample space for withdrawal from the assembly hall,
