Some Aspects Of Soil Moisture In The Forest, Ian J. Craib

Yale School of the Environment Bulletin Series

By determining the moisture content of carefully selected soil samples taken at various depths down to three feet, the moisture content of soils in the forest and in the open have been compared. The soils investigated were similar in their mechanical properties. Part I is an investigation of the effect of forest cover on the amount of water in the soil over the growing season and its availability. Part II is an investigation of the effect of root competition on the available water supply of forest soils.

"Triassic-Jurassic 'Red Beds' Of The Rocky Mountain Region": A Discussion, John B. Reeside Jr.

United States Geological Survey: Staff Publications

The conclusion drawn by Professor E. B. Branson in a recent paper on the "Red Beds" of the Rocky Mountain region that parts of these beds are marine is considered likely. The conclusion that there exists no basis for subdivision of the beds is not accepted, and a division of the Mesozoic part into Lower Triassic, Upper Triassic, and Jurassic units is advocated. The conclusion that no eolian deposits are present likewise is not accepted, and the interpretation of important parts of the Jurassic unit as eolian is advocated. Disagreement is expressed with much of Professor Branson's correlation table, and …

Thomas Chrowder Chamberlin's Contribu-Tions To Glacial Geology, William C. Alden

United States Geological Survey: Staff Publications

So prominent did Thomas Chrowder Chamberlin become in the field of glacial geology that it is a matter of some interest and importance to consider what was the status of the science at the time he turned his attention, as a student and a teacher, to it. So voluminous is the literature of this subject that it is obvious that one cannot in a sketch of this kind give even a general summary of the many books and papers on the subject published in this country, even were it desirable to do so. The intention is to indicate only what …

The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

The ponderous mandible of the great shovel-tusked mastodon, Amebelodon fricki, was figured and described before it was practicable to remove the plaster cinches. In the meantime, this rare specimen has lain on its sand table awaiting the time when sections and casts could be made before mounting it permanently. A rare specimen, especially if heavy, unwieldy, and fragile, is rarely dismantled for study after it is mounted and installed in its case. A gelatine cast of the alveoli has been made, and through the assistance of Mr. Murray Jerome Roper, a cast of the left mandibular tusk has just been …

A Study Of The Basal Cherokee In The Rolla Area, Thomas Daniel Murphy

Masters Theses

"The occurrence of outliers of Pennsylvanian age, probably Cherokee, in and about Rolla has long been known. The Bureau of Geology and Mines and the Department of Geology of the School of Mines at Rolla have been greatly interested in the many stratigraphic problems presents. The writer has, therefore, undertaken field and laboratory studies of certain of these problems"--Introduction, page [1].

Geological Report Of Summer Field Trip 1928, Clarence A. Corry, Marcus Mccanna

Bachelors Theses and Reports, 1928 - 1970

The object of this trip and report was to familiarize the students of the Montana State School of Mines with methods of taking and mapping surface and undergound geology. All surface geology was mapped by means of plane table and alidade, and undergound work by means of Brunton compass and taps.

The senior class of the Montana State School of MInes under the supervision of Dr. E.S. Perry performed the work, which covered an area in Madison County including South Boulder Creek, near Jefferson Island, the Silver Star Mining District, and the Alameda Mine, near Virginia City.

The Devonian Of The Bear River Range, Utah, I. Lavell Cooley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The geological column in northern Utah has had very little detailed study. Those who have made reports on this section have done so only in a very general way, making no detailed sections of any part of the column, excepting that of the Cambrian made by Walcott.¹ Other work has been done by Mansfield² in southeastern Idaho and a general section of the Devonian made in Green Canyon, Bear River Range, Utah by Kindle.³

Due to the lack of any detailed work of this nature being done in the Bear River Range, suggested the matter of making …

Tree Planting In Nebraska

Conservation and Survey Division

Introduction. This bulletin is planned to further the planting of trees and ornamental shrubbery in Nebraska. It is the result of cooperation between State, Federal, and University departments, and many State organizations.

The tree-planting campaign of this year (1928) is to begin early in the season and culminate in the American Forest Week (last week in April). It is a State and National movement, a welfare project worthy of the support of every citizen. The cooperation of all Nebraskans is invited.

Heavy Minerals In The Roubidoux And Other Sandstones Of The Ozark Region (Mo.), Cletus Daniel Cordry

Masters Theses

"In this study an attempt has been made to determine the usefulness of heavy minerals for correlation of formations over a limited area, in the heart of the Ozark uplift in southeast Missouri. The Roubidoux formation, already definitely correlated by other means, has been rather systematically sampled throughout the area, and the heavy minerals determined to ascertain their dependability for correlation purposes. Several samples from other horizons have been studied for comparison with the Roubidoux. Also, within the area studied there are numerous isolated patches of sandstone, the horizons of which have not been definitely determined. Samples from a few …

Archidiskodon Maibeni, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

Archidiskodon maibeni was first described in Bulletin 10 of the Nebraska State Museum under the title" Skeletal Parts of the Columbian Mammoth, Elephas Maibeni." * Dr. Henry Fairfield Osborn finds it expedient to found a new genus, Archidiskodon, to include the earlier and more primitive mammoths. Hence the change in the generic name. t'Mammoths and modern elephants have long been grouped together under 'the genus Elephas. Subdividing the genus does not necessarily do away with this convenient and rather familiar old arrangement.

Directory Of Certain Alumni The Department Of Geology And Geography The University Of Nebraska, E. F. Schramm

Bulletin of the University of Nebraska State Museum

In the Department of Geology and Geography, The University of Nebraska, there have been over 10,000 registrants between the years 1891 and 1926. So many inquiries have been received concerning alumni and their addresses that it seems advisable to publish this directory. The list is necessarily incomplete since many of the alumni have not informed the Department respecting their addresses and change of positions. Out of the total number of those who have pursued professional vocations the following have kept in close touch with the Department.

Prosthennops Xiphodonticus, Sp. Nov. A New Fossil Peccary From Nebraska, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum

During the field season of 1915, while collecting, a mile or two west of Valentine, Cherry County, Nebraska, Messrs. A. C. Whitford and J. B. Burnett secured for the Morrill-Maiben Palaeontological Collections, The Nebraska State Museum, The University of Nebraska, a finely preserved jaw of a small fossil hog, or peccary, belonging to the genus Frosthennops, accessioned No. 85-11-8-15B. & W.

The mandible under consideration was preserved in fine sand and is without blemish save that the condyle and coronoid are wanting. The dentition is perfect. In allusion to the sword-like tusks, which are unduly large, the species name xiphodonticus …

An American Fossil Giraffe, W. D. Matthew, E. H. Barbour

Bulletin of the University of Nebraska State Museum

A fragment of the lower jaw of a large fossil mammal with two well-worn teeth was dug up in June 1918, at a depth of 20 feet, while digging a cess pool at Bradshaw, York County, Nebraska. This unique specimen, accessioned 7-7-18, was brought to the Nebraska State Museum by A. Archie Dorsey, and was donated by C. B. Palmet, both of Bradshaw. It undoubtedly occurred in loess, which is thickly as well. as extensively developed in this region. It is a ruminant jaw, the teeth preserved being P4 and m1. The characteristic pattern of the premolar excludes reference to …

Notes On Nebraska Fulgurites, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Some six or eight years ago the writer contemplated a study of Nebraska fulgurites, both in the field and in the laboratory. In the meantime however, it proves to be superfluous for, after supplying Mr. A. E. Anderson, of the American Museum of Natural History, with certain material and data he proceeded in a masterful way on a technical inquiry, and it is with pleasure that, although delayed in publication, his findings follow in Bulletin 7 of the Nebraska State Museum. The present paper will deal as briefly as possible with the mode of occurrence and gross structure.

Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson

Bulletin of the University of Nebraska State Museum

So much has been written during the past century on the origin, structure and occurrence of fulgurites, or lightning tubes, found in many parts of the world that it would seem as though little remains to be added to the literature on the subject; but the discovery of a considerable number of unusually large and complete specimens in Holt and Stanton Counties, Nebraska, which exhibit remarkable definition of the particular features that have occasioned so much controversy regarding their formative processes, has added an important type to the representatives of this phenomenon and afforded clearer interpretation of the origin of …

Skeletal Parts Of The Columbian Mammoth Elephas Maibeni, Sp. Nov., Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

The skeletal parts of Elephas columbi are said to be unknown, although teeth, jaws, and skulls are common enough. Columbi is a mammoth of southern adaptation, hence its parts are found from Nebraska southward. Elephas columbi occurs abundantly throughout the State and many examples are preserved in the Nebraska State Museum, as will be seen in an accompanying list.

Tetrabelodon Abell, Sp. Nov., Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum

Brown County, Nebraska, which has been so prolific of long-jawed mastodons, has yielded another form which seems to be new and which may throw light on certain small tusks that occur where Tetrabelodon bones abound. Heretofore, we have considered these to be embryonic, but they show apparent wear, and in other respects they are enigmatic, and at best, atypical. Tetrabelodon tusks proper, however young, are typical, and are obviously tusks in miniature. The tusks in doubt are of varying lengths and about the diameter of one's thumb, but taper backwards, are worn to a bluntly oblique point, and are slightly …

Manganese Fulgurites, Harold J. Cook

Bulletin of the University of Nebraska State Museum

During August, 1924, while doing reconnaisance work near the head of Chugwater Creek, Wyoming, on the ranch of Mr. J. L. Jordon, the writer's attention was called to some unusual and interesting specimens found in a limited area, perhaps an acre or so, on the slope of the small butte flanking the Chugwater Valley. The hills of the region are of Tertiary age, the particular spot under consideration being Oligocene, the Brule stage, or Oreodon beds.

Hackberry Conglomerate A New Nebraska Rock, Erwin Hinckey Barbour

Bulletin of the University of Nebraska State Museum

In the cabinets of the Nebraska State Museum are several excellent rock specimens, which at first sight pass for pisolite, which they simulate. Scrutiny shows that they are hackberry seeds in sand, cemented by lime and clay into a firm, compact rock. The term hackberry conglomerate seems apropos.
