1933, Annual Report 54
The appropriations made directly for the work of the Geological Survey for the fiscal year 1933 included 12 items, amounting, to $2,181,000. Of the balance remaining in the 1932 appropriation for topographic surveys, $150,000 was continued available for expenditure during the fiscal year 1933, and the sum of $284,400 was transferred to the Geological...

A newly discovered pegmatite deposit near Ohio City, Colorado, is chiefly lepidolite, massive topaz, beryl, and albite, with some samarskite and columbitc. Three parallel pegmatite dikes, cach about 11 fect thick and 300 feet long, cut black schist. The minerals arc banded parallel to walls, with the following succession from walls to center; fine‐grained albite...

The specific yield of a water-bearing formation is defined as the ratio of (1) the volume of water, which after being saturated, it will yield by gravity to (2) its own volume (O. E. Meinzer, Outline of ground-water hydrology, U.S. Geol. Sur. Water-Supply Paper 494, p. 28, 1923). It is...

Structural evidence, particularly in the deeper mine‐workings, indicates that the volcano, which is of Tertiary age, was developed by explosive eruptions at a number of points along intersecting fissure‐systems that had been formed in pre‐Cambrian granite by east‐west compression, probably during the Laramide revolution. The volcanic breccia, which consists principally of...

The Magdalena District in central New Mexico comprises the Magdalena Range and Granite Mountain which are block mountains of the Basin Range type. They consist of Carboniferous sedimentary formations on a pre-Cambrian basement and are covered by Tertiary volcanic rocks.Volcanism in the District was preceded by considerable faulting, tilting, and...

The theory of rock‐pressure as a cause of artesian‐head dates back at least to early Grecian times. Thus the philosopher Thales, about 600 B.C., taught that the springs derive their water from the ocean through subterranean channels and that the water is lifted to the springs by rook‐pressure. The theory of rock‐pressure has had...

In many areas along the sea-coasts of the world the water-supply for human use is derived largely, and in some areas wholly, from underground sources. Because of the proximity to the ocean in these areas, in some respects the geologic and hydrologic conditions that govern the occurrence and movement of...

One of the outstanding accomplishments of recent years in connection with the study of the geologic source of groundwater and the quality of water yielded by different formations has been the development of methods and equipment for the exploration of wells. The description and use of the deep‐well current‐meter on well‐exploration work in Hawaii and New...

Investigations by the California Department of Public Works, Division of Water Resources (based on written communication from Harold Conkling, Deputy State Engineer)—the Division of Water Resources, California Department of Public Works, has in the past year conducted investigations of ground‐water...

On December 20, 1932, much of the western United States felt a pronounced earthquake‐shock which caused noticeable fluctuations of the water‐surface in several observation‐wells and at two stream gaging‐stations in the Mokelumne Area, central California. These effects of the earthquake are reported briefly in this paper.According to Dr. Byerly (personal...

The moisture‐equivalent and specific retention have been widely used as quasi‐physical constants to measure the power of a water‐bearing material or a soil to retain water against gravitative force. Comparatively little has been demonstrated, however, as to the relation of one to the other. This paper is...

1933, Report
The Volcano Letter was an informal publication issued at irregular intervals by the Hawaiian Volcano Observatory (HVO) during the years 1925 to 1955. Individual issues contain information on volcanic activity, volcano research, and volcano monitoring in Hawaii. Information on volcanic activity at other locations is also occasionally included.The Volcano Letter...

In this instalment** the iron ore deposits of the Lake Superior States, which normally furnish about 80 per cent, of the annual output of the United States, are described together with historical notes on discovery and transportation of ore. Deposits in the Mississippi Valley and Western States are likewise outlined...

This report contains, with the exception of a comparatively small number, all the decisions rendered by the board from its organization in 1890 through June, 1932, and supersedes all previous reports. Not included in this report are such decisions as have either been vacated, or, being revised, have been replaced...
