From Scope of Report: "This report is in two parts-the major or first part is a discussion of the results obtained from field studies of the factors responsible for the deposition of paraffin and the congealing of oil and of practical methods of combating these problems. The second part of the report deals with the analyses of crude waxes or paraffin obtained from different representatives crude oils."

From summary: This report details the survey of the potash field of southeastern New Mexico and adjacent parts of Texas. The material described in this report was obtained from drill cores and well cuttings.

From introduction: The purpose of this report is to describe the geology of the Elk Hills and the occurrence of the oil and gas, to trace the movements of oil, gas, and water in the developed areas, and to discuss the oil possibilities of the undeveloped parts. The history of the field and its production also are set forth.

From Introduction: "That the percentages of extraction of petroleum from the ground may and undoubtedly will be greatly increased in the future by underground mining methods where natural conditions will permit seems logical. The limitations imposed by depth, temperature, and flow of water under high pressure through the sands will be discussed later."

From abstract: This report is one of a series of publications by the United States Geological Survey on the Appalachian coal, oil, and gas fields. The area described occupies 227 square miles in Allegheny, Butler, and Westmoreland Counties, in western Pennsylvania, immediately north of Pittsburgh.

Introduction Object and Scope of Paper: "This paper attempts to assemble and discuss briefly in one volume a number of subjects relating to the mining of gold, particularly from lode deposits, in the United States and Canada."

Report compiled by the U.S. Bureau of Mines including statistics on fatal and non-fatal accidents in coal mines located in the United States as well as data regarding the various operations (e.g., number of miners employed and average production). The information is organized into tables for comparison and the text draws some overall conclusions in the summary.

Outlines of the activities and accomplishments of the national and international standardization agencies.

From introduction: The detailed information concerning the coal deposits of the Ashland field set forth in this report has been obtained in the course of an investigation that has been conducted both as a part of the United States Geological Survey's general systematic study of western coal lands and as an aid in the administration of the public lands. With the information obtained on the location of outcrops, the number, distribution, and thickness of coal beds, the accessibility of the coal, and the thickness of the overburden, the public lands of the region are classified as to their coal value; coal-bearing lands are differentiated from noncoal-bearing lands; and the administration of the coal-land leasing law is facilitated.
