Increasing emphasis has been given in recent years to the installation of wells in sand and gravel deposits along perennial streams. Under favorable conditions water enters the aquifer from the adjacent stream so that the safe yield is not limited by recharge from local precipitation [see “References” at end of paper, Jeffords, 1946]. Some of the installations tested, however, have not been successful. At times the preliminary investigations have been inadequate, and often quantitative hydrologic techniques have been applied without adequate consideration of the existing local conditions.

The strong eruptive activity that began in mid‐March, marked on March 17 by the formation of a new boca with a short‐lived volcancito and by external changes in the form of the cone, continued until April 18, The period April 12–18 was marked by bomb‐showers and explosive blasts at the rate of ten to 15 a minute, mostly from the south vent of the double crater. Most of the bombs fell into the north crater and on the north flank of the cone. From April 19 to 26 the activity was, in general, very weak, and little ash and few bombs were projected beyond the rim of the cone, Explosions were very rare, and the weak vapor column from the Volcano was accompanied by a dull surf‐like roar. Most of the vapor emerged from a small vent near the center of the divide between the two coalescing craters. A heavy ash column, at times approaching in intensity that of 1943, emerged from the Volcano from April 27 to 29. The ash was erupted from both the north and south vents of the crater, though the south vent is believed to have contributed the most. From April 30 to May 3 the activity was again very weak, and only a feeble column rose above the cone.

Hobbs propounded in 1910, is today still the only definitely formulated theory concerning the atmospheric movements that take place over an ice sheet of large extent. It stands chiefly on deductive grounds and contains several features that to climatologists as well as to glaciologists have always seemed questionable. Aside from the need of its verification for scientific reasons, there is now also urgent practical need for reliable information about the weather conditions that prevail over the ice sheet of Greenland, for Greenland lies athwart several of the great air routes of the future. In this paper, accordingly, the glacial anticyclone theory is first analyzed and then confronted with the facts of observation that are now at hand, especially those reported from the fixed meteorological stations which were maintained in the interior of Greenland during the 1930s.
In this, the first part of the paper, the meteorological data from the Eismitte station of the German Wegener Expedition are reviewed. The second part will cover the areological data of that expedition and the similar material from the other ice‐cap stations. The conclusions reached are that there is no evidence of a virtually permanent “glacial anticyclone” centered over the Greenland ice sheet. On the contrary, there is consistent evidence from all parts of Greenland that the weather over the ice sheet is controlled by alternating cyclonic and anticyclonic movements. Cyclonic activity is most intense in southern Greenland and weakest in northern Greenland. The entire ice sheet is supplied with snow brought by rising maritime air masses, not by air descending from the upper troposphere. Aviators need not expect so much as a fifty‐fifty chance of meeting with good weather on flights across central Greenland, except for a few weeks in midsummer.

The honor of being the first white man to see Great Salt Lake is claimed for a number of explorers and trappers who visited the region in the twenties and thirties of the Nineteenth Century. Among these were Etienne Provot and James Bridger, who were in the region in 1824–25, each quite unaware of the other's activities and discoveries.
In 1833 Captain B. L. E. Bonneville dispatched a party from his camp at Green River, Wyoming, for the purpose of exploring Great Salt Lake. This party attempted to make a circuit of the lake, chart its outline, and trap all the streams en route, but the attempt was abandoned because the great barren salt plains west of the lake were so hazardous that the party was in grave danger of perishing.

Rorabaugh (U.S. Geological Survey, Louisville, Kentucky, August 27, 1945)—In regions where snow is not a factor there is some advantage in making forecasts based on the effects of travel time and base flow. However, the runoff which results from precipitation during the period of forecast usually constitutes a substantial portion of the flow in many streams, and accordingly these predictions may be highly speculative.
The authors state that on March 1 an average of 52 per cent of the winter flow of Parker Creek has passed the gaging station on that creek while only 36 per cent of the winter flow of the Salt River has reached Roosevelt Reservoir. The forecast is based on this lag, which would approximate 16 per cent of the winter flow of the Salt River or about 25 per cent of the flow during March to May. In giving reasons for the lag the authors minimize the effect of accumulated snow, because less than 15 per cent of the Salt River Basin is thought to have accumulated snow. It may be, however, that the snow on this portion of the basin is the principal reason for the lag. The snow cover accumulates at high altitudes, where precipitation is heaviest and temperatures lowest. As losses will be proportionally less in these low‐temperature areas than in the remainder of the basin, it follows that storage of 25 per cent of the flow could result from snow accumulation on less than 15 per cent of the basin.

Some new members were added during the year in order to strengthen the representation of the committee in certain phases of runoff research. Norbert H. Leupold submitted his resignation in April because his work is no longer directly related to runoff‐research.
At the beginning of the year members of the committee met to discuss its setup and plans for the future. The committee has two subcommittees, one dealing with floods and the other with subsurface‐flow. The question was considered whether progress might be facilitated by the addition of one or more additional committees dealing with logical classifications of the subject of runoff. The confusion in nomenclature and terminology relating to runoff was discussed,but it was thought that the present time was not fitting for comprehensive consideration of standardization. It was considered important that the writer of a paper dealing with runoff should make clear the usage of terms he follows In his paper. It was emphasized that there is still an important need for better understanding or liaison between groups dealing with the influence of land use on stream‐flow and those dealing with control and development of streams.

The Committee on Runoff conceived the idea that it would be profitable to consider some of the terms which are especially pertinent to the field of runoff. That consideration was the principal Committee project of the past year and is featured in this report.
The Chairman sent a letter to the members of the Committee that was planned to draw out a symposium of opinions on the subject. A good starting point seemed to be the classification of water on the Earth. Meinzer's well‐known classification was given: atmospheric water, surface water, and subsurface or subterranean water. Comments were solicited.

In order to make this survey, the field was divided among a number of subcommittees, including a Subcommittee on Tectonics, of which the writer was chairman. Preliminary reports, discussing the research possibilities in the various fields covered by the subcommittees, were submitted in January, 1946, and concrete recommendations were formulated by the Research Committee at the Chicago meeting of the Association in April 1946 [Lowman, 1946]. Final reports of the subcommittees will be published later in 1946 in the Bulletin of the American Association of Petroleum Geologists.

They are on the southeast flank of a northeast-trending anticline which is partially overridden from the southeast by the Bays Mt. thrust sheet. The beds show low dips. The area is transected by a series of high angle strike-slip faults having relatively small displacement and striking essentially parallel to the dominant northeast structure. Minor cross folds running transversely to the regional structure are numerous. Three sets of fractures trending N. 45-50 degrees W., N. 30-40 degrees E., and N. 60-70 degrees E. are well developed.
The ore bodies are irregular but generally have a distinct elongation. The vertical extent may be limited to a single bed or may include several beds, depending upon local structural conditions. All ore bodies are confined to zones of pre-mineral deformation. The linear trends of the ore bodies show a remarkable parallelism to the axes of the cross folds. Ore occurs on any part of the flexures but maximum concentration is on the anticlinal crests and synclinal troughs: the ore attains greatest thickness on the anticlines. Fractures associated with the folding exhibit local ore control. Faults are poor sites for ore, but fracturing and drag folding accompanying faulting produce conditions favorable to ore deposition.

Clays derived directly from volcanic materials are composed dominantly of montmorillonite; but these clays, with the exception of the beidellite-nontronite varieties, have relatively low percentages of available alumina. In contrast, clays derived by thorough leaching of various aluminous rocks under conditions favoring thorough drainage are composed dominantly of kaolinite and when sorted by sedimentary processes form high-grade deposits; furthermore, the depositional structures of these sedimentary clays have favored the derivation of gibbsite through weathering, resulting in an increase in the alumina content of the clays. Kaolinite, gibbsite, and dickite all have relatively high percentages of available alumina.

The fault in which the lode is located offset the pre-Cambrian quartzite and slate walls about 4,500 feet prior to deposition of the overlying thick San Juan tuff. Late Tertiary faulting extended the fissure into the San Juan tuff, dropping the south side about 80 feet. Although most of the lode crops out in the pre-Cambrian rocks, it extends upward across the profound unconformity into the tuff. The lode is complex, containing sharply marked fissure veins, sheared slate dragged into the fault zone, a sheared dike, breccia chimneys, and pebble dikes. An assemblage consisting of quartz, sericite, kaolin, and pyrite appears to be of early Tertiary age. The more productive part of the lode, however, is late Tertiary and consists of a hematite chimney inclosing a copper shoot, a tungsten chimney, and compound base-metal fissure veins. These chimneys and veins are mostly localized along early Tertiary structures, but their mineral sequences correlate them with the second stage of late Tertiary deposition recognized by Burbank in the adjoining Red Mountain and other districts. The Dunmore lode, however, is believed to have been deposited at greater depth and higher temperature and nearer to a source of supply than the lodes of these districts. In structure as well as mineral assemblages the Dunmore lode shows a connection between the chimneys and veins of the region.

S. Geological Survey since 1939 indicate that economic deposits of chromite rich in normative spinel ((Mg, Fe)Al 2 O 4 ) occur in peridotites which are closely associated with gabbro; high-chrome chromites occur in feldspar-free peridotites; and chromites rich in both normative chromite ((Mg, Fe)Cr 2 O 4 ) and magnetite (FeFe 2 O 4 ) are found in the pyroxene-rich stratiform complexes. Reaction of high-alumina chromite with diopsidic gabbro to form anorthite, olivine, and enstatite is described, and some probable equilibria between chromite and silicate minerals are discussed.
A plot of 63 complete analyses on a triangular prism of composition shows that chromites from different geologic provinces in the Western Hemisphere vary consistently and fall in overlapping, but distinct, fields. The chromites of the Caribbean Province, which occur in dunite and troctolite, have the general formula Cr (sub 25-80) Al (sub 15-75) Fe (sub 1-5) (Mg (sub 65-75) ) and average about Cr 50 Al 47 (Mg 70 ). The chromites of the Pacific Coast, which occur in dunite and saxonite, average about Cr 70 Al 24 (Mg 60 ) in the range Cr (sub 60-77) Al (sub 16-35) Fe (sub 3-12) (Mg (sub 45-75) ).
The stratiform deposits of the Stillwater and Bushveld complexes occur in harzburgite and bronzitite, and are very much alike, averaging Cr 60 Al 32 (Mg 52 ) and Cr 58 Al 34 (Mg 44 ) respectively. Chromites from gabbroic facies of the Bushveld complex are much richer in normative magnetite, presumably reflecting a higher CaO: Al 2 O 3 ratio in the silicate environment.

Their full utilization requires systematic development based on the geology and hydrology of the aquifer and the principles of hydraulics distinctive of ground water. The methods of increasing recharge are of two kinds: (1) Indirect methods, in which increased recharge is accomplished by locating production wells as close as practicable to areas of rejected recharge or natural discharge, and (2) direct methods, in which water from surface sources is conveyed to points from which it percolates into a body of ground water. The direct methods can also be divided into two groups: (1) Recharge by surface application, and (2) recharge through wells. This paper discusses the different methods in relation to geologic structure and ground-water hydraulics and gives numerous examples.

As in most other parts of the Florida peninsula, these limestones are overlain by the Hawthorn formation of Miocene age which contains relatively impervious beds. The Hawthorn at Orlando is 45 to 200 feet thick and prevents or retards natural recharge to the lime. stones except where it is penetrated by what appear to be old sinkholes that are now filled with pervious material.
Owing to the lack of adequate surface drainage, more than 200 wells have been drilled into the limestones in the Orlando area to drain streets, control lake levels, and dispose of sewage and other waste liquids. Generally the piezometric surface of the water in the limestones is fat enough below the land surface to allow drainage by gravity. As the limestones are cavernous, most of the wells have large capacities for receiving water and seldom become clogged although a considerable amount of rubbish is carried into them.
The piezometric surface is conspicuously higher where drainage wells are concentrated, probably because of recharge through wells. However, the effect of the artificial recharge cannot be clearly differentiated from that of natural recharge. A deep-well current meter was used to determine the horizons at which the polluted surface water enters the limestones.
The investigation was made in cooperation with the Florida Geological Survey and the Corps of Engineers of the U.S. Army.

This was over 20 million gallons a day more than the natural recharge to the glacial outwash sand and gravel from which the wells draw the water. The ground water is especially in demand because of its uniformly low temperature throughout the year. In order to stop the resulting serious decline of water levels and decrease in yields of wells, the pumpage is now gradually being reduced. Also, the recharge has been increased about 2 million gallons a day by introducing water into the aquifer through wells.
During the spring of 1944 the Seagram and National distilleries helped solve a local shortage of ground water by recharging the underground reservoir with 1.7 million gallons a day of cold water from the municipal river-water supply. While this water was being added to the aquifer through several supply wells the plants were operated with additional city water, and the rest of the supply wells were kept idle. In this way, the large cone of depression in the water table that had been created by heavy pumping from the wells was practically filled with cold water from a combination of natural and artificial recharge. As a result, during the summer when the city water became too warm to be used in the plants, an increased and ample supply of cold water was available from the wells. It has been suggested that other industries at Louisville might adopt similar procedures for insuring adequate supplies of cold water during the summers.

The work was continued throughout 1943 and took survey geologists into some 20 states in which over 1,400 deposits or reports of deposits were examined. Of the numerous highly varied occurrences of quartz examined, only the deposits in western Arkansas, in the Piedmont and Blue Ridge provinces of Virginia, North Carolina and Georgia and the placer quartz of Mokelumne Hill, California, were of sufficient promise to warrant detailed work. Production in 1943 from these areas totaled slightly less than 4 tons of oscillator quartz, over 85 per cent of which came from Arkansas.The Arkansas deposits occur throughout the thick, deformed Paleozoic shales, sandstones, and cherts exposed along the central belt of the Ouachita Mountains. Steeply dipping fractures closely related to the major folds control the deposition of most quartz.Clear quartz is confined largely to the terminal parts of primary crystals, which have developed without disturbance or interference, are commonly elongate parallel to their C axes and are bounded by relatively simple forms. Deposition of silica during and subsequent to the fracturing of crystals resulted in the formation of complex crystals which are characterized by extensive optical twinning and lineage structures, and commonly are bounded by aggregates of the simpler crystal forms. The principal defects in all types of crystals are twinning, smokiness, cavities, solid inclusions and fractures.The Arkansas quartz deposits include veins, sheeted zones and stock-works. They are largely cavity fillings, apparently deposited by rising, attenuated, hydrothermal solutions, at relatively low temperatures and pressures. Minerals associated with the quartz, which constitutes 90 per cent or more of the cavity fillings, include dickite and carbonaceous material, calcite, adularia, and chlorite. The constituents of the cavity fillings could have been derived principally from magmatic sources or more probably from underlying rocks, with small additions from the rocks enclosing the cavities. The complex vein fabrics apparently resulting from intermittent regional deformation during the deposition of the quartz, and certain structural relations of the deposits, indicate that they were formed in the final stages of the Ouachita orogeny, probably in mid-Pennsylvanian time.

Rates of recharge ranging from 3,000 to 125,000 gallons per acre per day have been measured at the Perth Amboy Water Works, where artificial recharge of the Old Bridge sand, of upper Cretaceous age, has been practiced for more than 40 years. At the Duhernal development, which also draws from the Old Bridge sand, four or five million gallons daily is now derived from artificial recharge. This rate will probably increase with further lowering of the water table near the lake. For many years the Princeton Water Company has pumped water from a stream for recharging the Stockton sandstone, of Triassic age. The Lake Mohawk-Sparta Water Company spreads water underground by means of covered, gravel-filled ditches to recharge a shallow aquifer in its well field. The City of East Orange spreads the water from several small streams over parts of the intake area of the Quaternary beds supplying its wells. The estimated total recharge there is about two million gallons daily. Closely related to artificial recharge are those instances wherein well sites are chosen to take advantage of potential recharge from existing bodies of surface water. At the Borough of Manville no water spreading operations are conducted, but about three quarters of the water from its wells is derived by recharge from the Raritan River. The silting of water spreading areas may impair their effectiveness considerably. In some instances the growth of aquatic vegetation seems to reduce the ill effects of silting.
