Long Island simulates in a general way an aquifer in the form of an infinite strip confined between parallel boundaries at constant head (sea‐level), over which recharge precipitation is assumedly uniform. The non‐steady flow of water in this idealized system is analyzed assuming provisionally that the effective thickness of saturated beds below sea‐level is great compared to the maximum height of

This report is based on two months reconnaissance in the summer of 1941 in the Eden Valley, Wyoming. The work is as yet far from complete and the conclusions presented here must be regarded as tentative. It is hoped that in the future more extensive geological work may be undertaken.The Finley site provides a promising opportunity for a determination of the age of the Yuma culture. The points and

Ground‐water has long been recognized as one of our important natural resources, but only in about the last 20 years has concentrated effort been made to place ground‐water hydrology on a quantitative basis. The quantitative approach to ground‐water work has been brought about largely through the leadership of O. E. MEINZER, Chief of the Ground‐Water Division of the Geological Survey, United State

The recent discovery of the widespread occurrence of helvite, a beryllium‐bearing mineral, at Iron Mountain, New Mexico, has aroused interest in the commercial possibilities of a mineral which heretofore has been considered to have only scientific significance. Helvite contains about 13 per cent beryllium oxide as compared with five to ten per cent beryllium oxide in the mineral, beryl, which at p

The Committee on Runoff was not formally constituted until February 6, 1943, when the members of the Section, as listed above, were asked to serve. At the suggestion of President CHURCH the Committee has been so selected that there is Nation‐wide geographic distribution from West to East with the majority of the Committee composed of younger men.If the 33 papers prepared for discussion at the regu

The very large service which the geologists and engineers trained in ground‐water hydrology are rendering in this country in the prosecution of the war is due largely to the effective organization for this purpose. The Federal agency in which this service centers is the Water Resources Branch of the United States Geological Survey. The Ground Water Division of this branch has a technical personnel

The personnel of the Committee at present is as follows:Harry Fielding Reid, Professor Emeritus of Geology, Johns Hopkins University, 608 Cathedral Street, Baltimore, MarylandWilliam H. Hobbs, Professor Emeritus of Geology, University of Michigan, Ann Arbor, Michigan Colonel Lawrence Martin, Chief, Division of Maps, Library of Congress, Washington, D.C.James E. Church, Professor of Meteorology and

Some of the large, low‐grade nickel‐copper deposits of Bohemia Basin, Yakobi Island, south‐eastern Alaska, which previously had been mapped and studied by the United States Geological Survey, were explored during parts of 1941 and 1942 by the United States Bureau of Mines. The Gealogical Survey interpreted the geologic features of the deposits as revealed by the work of the Bureau of Mines. The ex

In view of the shortness of time since the appointment of the writer to the Committee on Ground Water this report is confined to the technology and problems in the Gulf Coast Oil Province. Of course, many of the methods and practices would apply to most parts of the country however, some would differ materially from one region to another. The writer wishes to acknowledge the suggestions and commen
