Map of roadways in the Midwestern United States and southern portions of the Saskatchewan, Manitoba, and Ontario provinces of Canada. The map includes major towns, bodies of water, and boundaries. The map also includes an inset map of the four Canadian road map sheets in this series near the upper-right corner. Scale [ca. 1:2,217,600] (35 miles to the inch).

More than nine-tenths of the Upper Cretaceous rocks in northeastern Wyoming are fine-grained shales, mudstones, and calcareous marls. A comparative study of the mineralogy, chemical and mechanical composition, density and porosity, fissility, and lamination of samples of these rocks discloses several relations that throw light on the geologic history and structural deformation of the region, and perhaps on its oil and gas possibilities.

From Introduction: The work on which this report is based consisted of detailed field and office studies which occupied the greater part of the summer of 1927. During this period mapping was done with plane table and telescopic alidade on a scale of 1 inch to 1,000 feet, and wells, faults, and outcrops within the productive part of the Teapot field were located in detail.

This bulletin tools and methods of tilling which can help reduce or control soil blowing and soil erosion on farms in the northern Great Plains of the United States. Among the crops discussed with relation to tilling methods are beans, corn, sorghum, potatoes, alfalfa, and sweet clover.

"The information given in this bulletin should enable farmers in the Great Plains and Western States to select from the more common species of grasses some one or more suited to their needs [for soil and water conservation]. Common harvesting equipment and farm machinery can be adapted to the proper handling of native grasses. This brings the cost of such work within the means of most farmers." -- p. i. Among the grasses discussed are wheatgrass, buffalo grass, bluestem, grama, Bermuda grass, wild rye, hilaria, Sudan grass, bluegrass, panic grasses, dropseed, and needlegrass.

"Revegetating deteriorated range lands by sowing adaptable, nutritious, and palatable grasses is vital for adequate forage production in the Intermountain region, for profitable livestock raising, and as a safeguard against flood and erosion damage. The effect of serious droughts, greatly aggravated by overstocking, has resulted in the replacement of valuable perennial grasses by annual weeds and grasses that have much less value as forage for livestock or for proper soil protection. The abandonment of unsuccessful submarginal croplands has also added greatly to the vast acreage of deteriorated but potentially productive range lands of the region in need of revegetation. Proper guides and procedure for revegetating run-down ranges and abandoned dry farms by artificial reseeding are necessary to safeguard against costly pitfalls and to insure reasonable success. The procedures herein outlined are based on the experiences and research to date and should prove helpful to those administering range lands and producing livestock in the region comprising Utah, Nevada, southern Idaho, and southwestern Wyoming, commonly referred to as the Intermountain region." -- p. i

Revised edition. "This bulletin applies both to the western portions of the United States in which ordinary farm crops are grown largely under irrigation and to western Oregon and Washington where irrigation is not essential for strawberry production but may be profitable. It describes methods practiced in the more important commercial strawberry-growing districts of the West; it aims to aid those persons 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 of irrigating other crops. Details must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid areas frequently suffer from drought which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those areas who could install irrigation systems at small expense. This bulletin gives information on soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, shipping, and utilization." -- p. ii

From introduction: This report describes the deposits of analcite in the Green River formation, to compare them with other similar deposits, and to present them with other similar deposits, and to present the observations and inferences that led him to explain them as alteration products of volcanic ash that fell into an ancient saline lake. The report also records the occurrence of several thin beds of sepiolite, or meerschaum, in the Green River formation and presents new data on the molds of saline minerals of the Green River formation whose determination affects directly the interpretation of the analcite and sepiolite deposits.

Abstract: The identification of new collections of fossil plants from the Green River formation of middle Eocene age made it necessary to reexamine the megascopic types of the Green River flora. This study resulted in the reassignment of some species and the rejection of such species as were based on fragmentary, indefinable specimens. The recent collections yielded 22 new species. Exclusive of the microscopic forms of thallophytes and pollens, the flora now numbers 135 megascopic species that are considered to be recognizable and distinctive. The new elements found in the flora do not alter the previously expressed opinion that the megascopic Green River flora lived in a warm-temperate well-watered environment.

From introduction: The geologic record of the Tertiary period in the Green River Basin of southwestern Wyoming consists, in a broad way, of two quite different parts. The history of the first part, lasting through the Eocene epoch and perhaps on into the early Oligocene, was recorded in a thick series of sedimentary rocks of fluviatile and lacustrine origin. The history of the second part was recorded chiefly by successive stages of stream planation and stream trenching, but also in part by fluviatile sedimentation and, in certain localities, by glacial deposits. The first part of the record is virtually continuous, though its interpretation is by no means simple and obvious. The second part of the record is distinctly fragmentary, and the evidence the fragments provide is difficult to evaluate and to integrate.

Outline of Problem: "This paper covers a survey of 19 ores collected from seven of the more important iron-ore districts of the United States and is a contribution by the ore-dressing section of the United States Bureau of Mines to general research program on iron and steel being conducted by the Bureau."

From Introduction: "This report covers the essential features of the asbestos industry, including occurrence, production, mining, milling, utilization, international trade, and marketing."
