Since the beginning of the science of hydrology attempts have been made to interpret these phenomena and determine their significance. On the basis of actual observations and “with special reference to Long Island, New York,” Veatch [see 1 of “References” at end of paper] in 1906 considered in some detail several different causes of water‐level fluctuations. He placed the known causes under two general headings, natural and human. However, considering proximate rather than ultimate causes a further classification might be, and indeed often is, made with regard to the conditions under which the fluctuations are produced by a given agency, natural or human. Thus we speak of ”water‐table conditions“ and ”artesian conditions,“ realizing, however, that the distinction between the two is not always definite. The phenomena peculiar to artesian conditions are usually the result merely of the imperviousness of the confining beds relative to the particular aquifer under consideration. Indeed, it is recognized that perhaps even the most dense clay is not absolutely impervious to the flow of water, given a difference in head, sufficient to produce the flow, though it may be beyond the precision of the means now employed to detect the flow of water through such impervious strata.

The first part requires a procedure for determining the amount and kind of runoff that occurs under various conditions. The second part is concerned with the shaping of the runoff into a discharge‐hydrograph for a particular gaging station. (Rainfall‐eccentricities often provide more difficulties than either of the above.)
Considerable investigation has been made and is being continued along both lines of research. The unit‐hydrograph and related methods now provide a means of shaping discharge‐hydrographs as accurately as is required by the practical considerations of most problems. However, it is believed that methods for determining the amount and kind of runoff which occur under various conditions have not been demonstrated to an equivalent refinement. It is with the latter problem that this paper is concerned.

Fluctuations of ground‐water as a result of earth‐tides, however, are not generally known although they were observed and studied in a flooded coal‐mine in Europe [2] as early as 1879, and later 1905 to 1912 in wells in South Africa [3].
The phenomena of earth‐tides first came to the attention of the writer in March, 1938, when studying fluctuations of the water‐level In an artesian well near Carlsbad, New Mexico, recorded on charts of a water‐stage recorder, which had an approximately semidiurnal period. Because of the distance from the ocean, about 500 miles, and the altitude of the water‐bearing formation, about 2700 feet, it appeared that the fluctuations could not be the result of ocean‐tides. Neither did it appear they could be the result of other natural phenomena such as changing air‐pressure or changes in water‐level of a nearby lake and river. There was no pumpage from the aquifer, so the fluctuations of the water could not be caused by pumping. T. M. Cramer, Resident Manager of the United States Potash Company at Carlsbad, New Mexico, suggested that the fluctuations must be the result of some lunar attraction. Further study of the fluctuation was made by Dr. C. V. Theis, of the United States Geological Survey, and the writer, whereby the effect of changing air‐pressure was eliminated by correcting the water‐levels to an assumed constant atmospheric pressure. In this study it was demonstrated after applying the barometric correction that the remaining fluctuations were fairly regular and progressed with the transit of the Moon. It was also demonstrated that the fluctuations were of the greatest amplitude during the period of new Moon. Further work by W. E. Hale, of the United States Geological Survey, and the writer, has shown that the fluctuations were much more regular and of greater amplitude during the periods of new and full Moon than during the first and third quarters. It was, therefore, concluded that they are related to true earth‐tides. A preliminary note was published in the Transactions of the American Geophysical Union for 1938 [4].

For this reason, the question as to the definitions of different kinds of subterranean water was selected as one of the three questions for discussion by the International Commission on Subterranean Water at the meeting in Edinburgh in 1936 and again (as Question No. 2) at the meeting that is to be held in Washington in September, 1939.
The purpose of the International meetings is not only to discuss subjects of mutual interest but also, so far as practicable, to make official decisions. Obviously, decisions on scientific questions should be made only after mature consideration and only on questions as to which there is general agreement. The reports that have been prepared in different countries on the question under consideration and the correspondence and oral discussion appear to show that the way is open for International agreement on some of the basic concepts. A comprehensive paper on the question was prepared for the Edinburgh meeting by Dr. Vasillevskij, of Russia (Internat, Ass. Sci. Hyd., Bull. 22, 1936). Dr. Yasilievskij, in a letter dated January 12, 1939, urges that a beginning be made at the Washington Assembly to adopt new terms on the basis of Latin and Greek roots, these terms to have strict meanings for all countries. The following are tentative suggestions for such a beginning, based especially on information from France, Germany, Great Britain, Holland, Japan, Russia, and the United States.

There was available at that time the Newtonian analysis of sources and sinks in a semi‐infinite medium which could be applied directly to ground‐contacts. Experiments conducted at that time showed that, while the electrical ground‐resistivity was a factor, it was under engineering control. In computing the resistance of a ground‐contact, Kennelly [see 1 of “References” at end of paper] equated the conducting surface buried in the ground to that of a hemisphere in a medium having a uniform resistivity, and the values so secured were within the safe limits of operation of telegraph‐ and cable‐lines. Later Ollendorf [2] gave a very much more detailed solution of a large number of different types of ground‐contacts for which was computed the current‐ and potential‐distribution in the ground immediately around the ground‐electrode. Wenner [3] also gave a classical solution for the measurement of ground‐resistivity by using separate current‐ and potential‐contacts to the ground which was good practice for measuring the resistivity of metal conductors.

The Marysvale Region is part of a large area of volcanic rocks, which occupies much of the High Plateaus of Utah (Fig. 1). It is believed that the Marysvale Region covers sufficient area to furnish an adequate sample of this volcanic area, and, though horizontal variations are known to occur, the study may serve as a guide as to what may be expected in other parts of the area. The chemical analyses are the most completely representative of any ever taken in this part of Utah, and they furnish a basis of comparison within the High Plateaus and with other areas in Utah.

An illustration (Fig. 1) from the old treatise by Agricola, “De Re Metallica,” published in 1580, will serve to show the implicit faith of that generation in divining methods. However, it was not until 1920 that real progress was made in prospecting by using the latest advances of the physical sciences. The public interest was stimulated by the successes of these methods on the part of commercial operators, and governmental agencies received many requests for information concerning their reliability. There were also, in the late 1920's, high‐pressure mine‐promotion schemes which used geophysical methods in a very questionable manner, symbolized in Figure 2 as of 1928 by an electrified forked stick. Authoritative information concerning such practices for public protection was needed to curb such notorious undertakings. Dr. Scott Turner, then Director of the United States Bureau of Mines, thoroughly understood the situation and was first in the governmental departments to recognize the possible value of a study of modern prospecting methods. The Bureau of Mines began this investigation by employing Drs. A. S. Eve and D. A. Keys of McGill University for short periods in the summer in 1927. Their first publication [see 1 of “References” at end of paper] served to illustrate the fundamental scientific principles which underlie geophysical prospecting. This was followed by a second publication [2] giving the results of field‐tests. In the light of the rapid improvements during the intervening ten years, these two papers take a historical position.

of the committee on underground waters, 1938–39","docAbstract":"In preparing the report of the Committee on Underground Waters of the Section of Hydrology for the final year of the triennium, it becomes evident that the collection of fundamental data relating to the hydrology of underground waters continues at a rate comparable to that maintained in the past few years, and perhaps even at an accelerated rate. Almost every extensive practical investigation of ground‐water supplies offers some opportunity for study of fundamental problems, in fact many of them require such fundamental study. With a larger number of investigations in progress, and with fairly liberal appropriations much new and valuable information is being discovered. Some idea of the increase in ground‐water studies since the organization of the Section of Hydrology may be given by a few statistics on the work of the Division of Ground‐Water of the Federal Geological Survey, which does the largest amount of ground‐water work in the United States. In 1932 the Division worked on about 50 projects in 25 States, in 15 of which and in Hawaii the investigations were made in cooperation with States, or other local Governmental agencies. During the current fiscal year work has been completed, or is in progress, on about 100 investigations in 35 States, Hawaii, and the Virgin Islands. The number of States cooperating on the work has increased to 24. During the current fiscal year about \\$375,000 will be spent for ground‐water investigations by the Federal Geological Survey and cooperating organizations, as compared to about $175,000 spent during the fiscal year ended June 30, 1932.

The determination of the quantity of water in ground‐storage is a difficult problem involving soil‐sampling, measurements of ground‐water wells, and measurements of the flow of small streams and springs. It has occurred to the writer that selected stream‐flow records for either the late fall or early spring might provide a better index of the ground‐water available for spring runoff than that obtained by other methods. This would involve a comparison of runoff in the fall with runoff in the spring, and might eliminate uncertainties in the relation of a reservoir‐level in the fall with runoff in the spring. Such a method would be especially desirable because of the availability of stream‐flow records. The discussion which follows is more an explanation of the method to be used than an attempt to develop an accurate formula for the prediction of spring runoff.

The drought has continued longer and has been more severe than any that has been experienced since the region began to be farmed. It has caused untold distress. Crops have failed for years in succession. In large areas in the so‐called dust‐bowl the top soil has been almost entirely removed by wind‐erosion and the dust‐storms have become so bad at times that the health of the inhabitants has been seriously threatened. In some parts of the region the annual rainfall, which ranges from about 18 to 24 inches, according to the location of the area, has returned to about the normal or long‐time average. In others the drought is still in progress and a partial or complete crop‐failure was again experienced in 1938. When the rainfall‐record is studied, it becomes apparent that a large part of the High Plains never should have been farmed and should be allowed to go back to the range, if indeed the native grasses can be restored. Other parts, however, can still be farmed with moderate success by the farmer who uses proper methods of cultivation and crop‐rotation, and combines farming with stock‐raising by keeping a part of his land in pasture and raising mostly feed‐crops. Irrigation, if it can be accomplished at a practicable cost, affords security both to the farmer and stock‐raiser.

To a considerable extent these variations relate to the physiographic and edaphlc features of the drainage‐basins as they have been developed by the geologic and climatic history of the particular province in which they are located. Although storms of high intensity occur throughout the United States, the runoff therefrom has been observed to have certain inherent characteristics in wet or humid areas that are different from those in arid or semiarld regions even though the laws governing the flow of water either over ground or in river‐channels are universal in application. Essential features of flood‐behavior in wet or humid areas where stream‐flow is sustained throughout the year and river‐channels and valleys are comparatively well defined and permanent, differ from those in arid or semiarld regions where stream‐flow is very erratic and flashy and the channels are formed largely by occasional intense runoff rather than the slow and orderly development by the continuous occupancy by flowing water. Moreover the flood‐problem in areas where a part of the precipitation occurs as snow differs from that in areas where all the precipitation occurs as rain. Furthermore, in areas where snow does occur there seems to be a wide range in flood‐runoff characteristics depending upon the temperature in and altitude of the particular zone. Some of the different flood‐characteristics as they relate to total runoff and the concentration thereof are described herein and possible reasons therefor are related to conditions which seem to be more or less inherent in particular physiographic and climatic provinces.

During this time, surveys have been conducted on the islands of Oahu, Molokai, and Maul. Two distinct types of ground‐water occurrence are being investigated: (1) The basal fresh‐water lens floating on underlying salt water in obedience to the Ghyben‐Herzberg principle (Fig. 2); and (2) perched ground‐water (Fig. 3) .

In 1938, as in previous years, the Committee devoted its energies primarily to the collecting of data on the variations in length and volume of American glaciers, it being felt that the maintenance of a continuous record of these variations is of prime importance, not only to hydrology and glaciology, but, as has become increasingly evident recently, also to climatology, geomorphology, geography, ecology, history, and archaeology. As the time available for the work of the Committee is limited and does not permit covering the entire field of glaciology, it seems best to devote it before all else to this line of research which yields results of value to so many different sciences. Besides, the gathering of data on glacier‐oscillations is not a one‐man job that can be taken up or dropped at convenience from time to time, but is an organized and far‐flung enterprise whose success depends upon the faithful cooperation of many volunteer workers located in different parts of the country. Such an enterprise, once launched, must be kept running or it will disintegrate and the precious enthusiasm of the field‐workers will be lost.

Measured discharges have ranged in quantity from a small fraction of a second‐foot measured volumetrically to more than 2,000,000 second‐feet measured by use of the current‐meter equipment recently developed by the Survey and described by the writer in the April 1938 issue of Civil Engineering. In this work, systematic and generally complete records of discharge are being obtained at about 3700 gaging‐stations maintained and operated by the United States Geological Survey. A typical structure at which records of river‐stages are obtained is shown in Figure 1. A discharge‐record at a gaging‐station is usually derived from a record of stage by means of a curve or table showing the stage‐discharge relation as determined by measurements of discharge distributed over the range of stage.
