As Long Island is the largest island on the eastern coast of the United States, and is of such size, 120 miles long and 23 miles wide, that it is a more or less noticeable feature on even very small-scale maps, little need be said of its general geographic position.

Geology and underground water resources of northern Louisiana and southern Arkansas

In the fall of 1902 arrangements were made with the Geological Survey of Louisiana for the writer to prepare a report on the geology and underground water resources of northern Louisiana. In the prosecution of this work it was found necessary, in order that the questions involved might be more thoroughly understood, to include that portion of the Coastal Plain in southern Arkansas southwest of Arkansas River, and the portion of northeastern Texas not discussed in Hill's exhaustive report on the artesian-water conditions of the Black and Grand prairies a After the Arkansas work was well in hand and before the Texas investigation had advanced beyond a few preliminary letters the writer was detailed to the Long Island, New York, investigation, which consumed the field and office time from February, 1903, to July, 1904.b The present report is thus based on the'field work of the fall and winter of 1902 and 1903, supplemented by several years' field work with the Geological Survey of Louisiana and private work in eastern Texas. It covers southern Arkansas and northern Louisiana and small portions of adjacent areas in Mississippi and Texas.

Record of deep-well drilling for 1904

In this report, which is the first of a proposed series of annual publications, are presented the results of the first six months' work by the United States Geological Survey in the systematic collection of well records and samples. Much time having been occupied in organization and preliminary correspondence, the results of only about three months' actual work are included. The report is issued for the purpose of giving to present or prospective well owners and drillers the results of drilling as reported to the Survey, with the object of furnishing them as good a basis as possible for future drilling in the regions discussed, and to afford geologists and others a more complete knowledge of the rock succession and structure. It is intended that the reports of the series shall present records of contemporaneous drilling rather than the results of past work, a special attempt being made to secure records accompanied by samples. The logs of completed wells, however, will be incorporated when practicable; but as records of such wells are seldom preserved for any length of time, their number will probably decrease in proportion to new wells as the work continues. All well records received during the year 1904 that were accompanied by complete sets of samples are presented in this report, as are also a considerable number furnished by drillers, contractors, well owners, etc., representing other completed wells. The report does not, however, include all records furnished the Survey, a great number being furnished by oil companies and others interested in the development of oil or mineral lands. Many of these are confidential and can not be published, while others will be compiled and embodied in reports on special regions, which will be published later.
