From Introduction: "The investigations described in this bulletin are confined to a study of the washing characteristics of bituminous coals. The washing characteristics of coals from many of the most important coal-producing fields of the Eastern and Central States were examined."

From introduction: The district discussed in this report embraces the entire northern peninsula of Michigan and the parts of northern Wisconsin and northeastern Minnesota that were covered by a re-advance of the Superior lobe of the Labrador ice sheet late in the Wisconsin stage of glaciation.

Revised edition. "This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3

Revised edition. This bulletin discusses methods for handling, loading, and transporting southern new potatoes in the United States. It explains the importance of grading potatoes, removing bruised and diseased potatoes from the crop before transport, and loading cars properly. Potatoes may be loaded into cars in barrels, sacks, and crates, but hampers should not be used.

Report issued by the Bureau of Mines discussing the demands on the oil industry due to an increase in automobiles in the United States. Improvements in drilling methods and refinery practices are presented. This report includes a table.

This bulletin discusses the cattle-fever tick and methods for controlling it. Possible methods include dipping, pasture rotation, and arsenical dips. The life history of the tick is also discussed.

Technical paper issued by the Bureau of Mines over experiments conducted on the back pressure of oil wells. The results of the experiments are presented and discussed. This paper includes tables, photographs, and illustrations.

This bulletin discusses the classes and varieties of hard red winter wheats and the areas in which they are successfully grown. Among the varieties discussed are Turkey, Kharkof, Kanred, Blackhull, Minturki, and Baeska.

"At least 66 distinct varieties of soft red winter wheat, known by nearly 400 different names, are grown commercially in the United States, and additional varieties are grown experimentally. These varieties differ widely in yield, adaptation, milling and baking value, and other characteristics. The most widely grown varieties in the United States in order of importance are Fultz, Fulcaster, Mediterranean, Poole, Red May, Red Wave, and Harvest Queen. The area of each of these varieties in 1919 varied from about 4,800,000 acres to about 1,000,000 acres." -- p. 2

From Introduction: "Responding to the imperative need for increasing to the utmost the petroleum supply of the United States, the Geological Survey, since we entered the war, has largely concentrated its investigations of oil fields in the most promising undeveloped territory, such as Wyoming and the midcontinent-Texas region, and especially in the Osage Reservation in Oklahoma. This report is therefore issued to supply an evident need for geologic information regarding the Osage lands. In the separate papers the most practical and immediately available conclusions reached by geologists as to the structure and oil prospects in the townships already examined are published for the immediate use of the oil man."

Patent for a cycle car that can be steered and propelled by hands only and can be used with ordinary bicycles.

Patent for a new and useful method of dealing the walls of deep wells in which the means for lining oil wells by the use of the customary metal casing is avoided, the cost is very materially reduced, and numerous expenses and failures are avoided.

Topographic map of a portion of Texas from the United States Geological Survey (USGS) project. The map includes towns, historic or notable sites, bodies of water, and other geologic features. Scale 1:125000

Patent for a method of sealing oil wells to avoid applying casing to the wells to prevent leakage, seepage, or cave-ins.

Patent for a linting machine (Carver type) that contains an air pocket at the end of the passage to prevent cotton from clogging the machine.
