In a letter dated June 26 to Dr. Van H. Manning, chief of the Bureau of Mines, notifying him of the coordination of war gas experimental work in the War Department, President Wilson wrote as follows :

I have had before me for some days the question presented by the Secretary of War involving the transfer of the chemical section established by you at the American University from the Bureau of Mines to the newly organized Division of Gas Warfare, in which the War Department is now concentrating all the various facilities for offensive and defensive gas operations. I am satisfied that a more efficient organization can be effected by having these various activities under one direction and control, and my hesitation about acting in the matter has grown only out of a reluctance to take away from the Bureau of Mines a piece of work which thus far it has so effectively performed. The Secretary of War has assured me of his own recognition of the splendid work you have been able to do, and I am taking the liberty of inclosing a letter which I have received from him in order that you may see how fully the War Department recognizes the value of the services.

I am to-day signing the order directing the transfer. I want, however, to express to you my own appreciation of the fine and helpful piece of work which you have done, and to say that this sort of teamwork by the bureaus outside of the direct war-making agency is one of the cheering and gratifying evidences of the way our official forces are inspired by the presence of a great national task.


GEODETIC SURVEY By executive order dated May 16, 1918, the President transferred to the service and jurisdiction of the Navy Department for temporary use the Coast and Geodetic Survey steamers Patterson and Explorer, including their equipment and personnel other than commissioned officers. These vessels have been employed for many years in surveys on the Pacific coast and chiefly on the coast of Alaska.

Since the beginning of the war the work of this bureau has been almost entirely for military purposes. Five vessels, three on the Atlantic and two on the Pacific coast, have been transferred to the Navy, and about twentythree per cent. of the personnel has been transferred to some branch of the military service. Of the remaining force most of the field officers are engaged in land or hydrographic surveys for the Army or Navy, and a large portion of the office force is employed in reducing and publishing the results thus obtained.

A very important part of the office work is the preparation and production of charts, coast pilots and tide tables for vessels of the Navy and Merchant Marine, including those operated by the Shipping Board, the Railroad Administration, the Coast Guard and the Bureau of Lighthouses. The officers of the Survey are trained in work of triangulation, precise leveling, astronomic work, hydrographic surveying and chart construction, and are particularly available for service as navigation officers in the Navy and for duty with the Corps of Engineers, the Artillery Corps and the Aviation Service of the Army.

MAGNETIC OBSERVATIONS The various parties sent out by the Carnegie Department of Terrestrial Magnetism and the United States Coast and Geodetic Survey, have all reported securing successful series of magnetic observations during the time of the total solar eclipse of June 8. Magnetic observations were made by the Coast and Geodetic Survey at Green River, Wyo., Mena, Ark., and Orlando, Fla. In addition data will be obtained from the various magnetic observatories of the Coast and Geodetic Survey.


The stations at which magnetic observations were made by the observers of the Department of Terrestrial Magnetism were: Goldendale, Wash.; Corona, Colo.; at an altitude of 12,000 feet; Moraine Lake, Colo.; Lakin, Kans.; Brewton, Ala., and Washington, D. C. At Lakin, furthermore, and at Washington, D. C., atmospheric-electric observations made. Reports on the results obtained will be published in the September issue of the journal Terrestrial Magnetism and Atmospheric Electricity. At various universities also series of magnetic observations were obtained and data will likewise be furnished by the Canadian magnetic observatories.

The magnetic survey vessel Carnegie arrived safely at her home port, Washington, D. C., on June 10, where she will be put out of commission probably during the period of the war. During her cruise from Buenos Aires, Argentina, around The Horn to Valparaiso, Chile, Callao, Peru, thence through the Panama Canal to Newport News, she was in command of Dr. H. M. W. Edmonds; the other members of the scientific staff aboard were: Messrs. A. D. Power, Bradley Jones, L. L. Tanguy, J. M. McFadden, and Walter E. Scott.

It is stated in Nature that the British minister of munitions, in agreement with the secretary of state for the colonies and the petroleum executive, has appointed a mittee to inquire into certain matters relating to the production of fuel oil from home sources. The terms of reference are: “ To consider the report which has been rendered by the Petroleum Research Department on the production of fuel oil from home sources, and to advise to what extent, and within what time, it should be possible under present conditions to carry out the proposals made in this report; and to consider the steps which have been taken by the Ministry of Munitions in this connection." The members of the committee are: Marquess of Crewe (chairman), Colonel A. Stirling, Major G. Collins, Engineer Vice-Admiral G. G. Goodwin (Engineerin-Chief of the Navy), Sir Richard Redmayne (representing the Controller of Coal Mines), Sir Lionel Phillips (representing the Ministry of Munitions); secretary, Mr. G. C.

The British Army Medical Advisory Board, established in 1901 has been in abeyance since the beginning of the present conflict. We learn from the British Medical Journal that it has now been considered advisable to appoint a new advisory board somewhat differently constituted and with a smaller number of members. The Director-General, Lieutenant-General T. H. J. C. Goodwin, is president, and the other members are Major-General Sir Bertrand Dawson, Major-General Sir Berkeley Moyniham, Colonel W. H. Horrocks, Colonel Sir Robert Jones and Lieutenant-Colonel Sir Harold J. Stiles. Sir Bertrand Dawson, who is physician to the London Hospital, is a consulting physician with the British Expeditionary Force in France. Sir Berkeley Moynihan, who is surgeon to the Leeds Infirmary, is consulting surgeon to the Northern

Command. Sir Robert Jones is the Inspector of Military Orthopedics, and Sir Harold Stiles, of Edinburgh is assistant inspector of Military Orthopedics for Scotland and was a member of the commission of inquiry in France. Colonel Horrocks, who was a member of the old board, again serves on the new board as sanitary expert. The secretary is Mr. A. T. Gann, who was the secretary of the old board. It will observed that the new board does not contain, as did its predecessor, representatives of the India Office and of the directorates of military operations and of fortifications and works.
