Geology And Ground-Water Resources Of South-Central Nebraska. With Special Reference To The Platte River Valley Between Chapman And Gothenburg, Alvin Leonard Lugn, L. K. Wenzel
Department of Earth and Atmospheric Sciences: Faculty Publications
The investigation here reported, which covered a period of about 5 years, 1929 to 1933, was made for the purpose of determining the available supply of ground water in south-central Nebraska, the origin and discharge of the ground water, and the relation of the geologic and ground-water conditions in the Platte River Valley to the conditions occurring under the plains to the south. The area was found to be underlain by permeable Pleistocene and Tertiary sand .and gravel, much of which is saturated and yields relatively large quantities of water to wells. Except in a few isolated places the ground-water …

SUMMARY
The Friedel-Crafts reaction has been used in the preparation of thiophene ketones, some of which were hitherto unknown. Certain limitations of the reaction have been noted.
The mercuration of thiophene ketones has been systematically investigated for the first time. Many new halogen derivatives of benzothienone have been synthesized. These were employed in the elucidation of the structure of a complex mercurial· derived from this ketone.
A new modification of an old reaction has been developed whereby benzothienone can be mercurated quickly and almost quantitatively. Interesting derivatives of this little known ketone have been synthesized. Chief among these are the …

Freestone County, Texas [Water Quality Survey Of Wells And Springs With Test Hole Data, 1936], Samuel F. Turner
United States Geological Survey: Water Reports and Publications
Introduction
The purpose of this survey was to obtain information concerning existing wells and springs and the quantity and quality of water they yield, and to put down test holes where additional information was needed.
This project was part of a statewide Works Progress Administration project known as a "Statewide Inventory of Water Wells," sponsored by the [Texas] State Board of Water Engineers. The Division of Ground Water of the United States Geological Survey cooperated in the technical direction of the project and the Bureau of Industrial Chemistry of the University of Texas furnished laboratory space and equipment and supervised …
