Some Kentucky Clays, Including Kaolinic, Plastic And Fire Clays: Clays In Several Parts Of Kentucky, With Some Account Of Sands, Marls And Limestones, Aug Foerste, James H. Gardner
Bulletin--KGS
The bulletin is preliminary in character and is offered now simply in order to meet the urgent calls for all information concerning our clays that is at present available. A more comprehensive report, in which not only the geology and distribution of our clays, but also their technological values, will be given, will follow in due course.
Data for such a bulletin are being gathered as rapidly as circumstances will permit. Among the clays upon which more field work is required are some of those associated with the coals and Conglomerate Measures of the Eastern Coalfield; those in other Lower …

Bulletin No. 89 - A New Centrifugal Soil Elutriator, P. A. Yoder
UAES Bulletins
Within recent years much has been done toward determining the agricultural significance of certain physical properties of the soil. The grade of fineness is the most important of these physical properties, in that it determines, to a large extent, other properties. The· mechanical analysis of soils has thus come to be considered of primary importance in soil investigations. Any improvements in the methods or apparatus for mechanical analysis will, therefore, doubtless be welcomed by agricultural investigators. Though this is a very recent line of work, still many devices have been introduced for the separation of soil on the basis of …
Present Knowledge Of The Distribution Of Daimonelix, Erwin Hinckley Barbour
Present Knowledge Of The Distribution Of Daimonelix, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Daimonelix when first discovered, in 1891, was thought to be confined to the elevated tablelands of central Sioux County, Nebraska. In the meantime its range has been extended and it is now known almost throughout the entire Arikaree formation, a tract probably about five hundred miles in diameter, situated in Nebraska, Kansas, South Dakota, Wyoming and Colorado. The more fibrous forms of Daimonelix constitute a character so constant as to justify the name Fibrous Arikaree for the upper half of the formation.

Report On The Progress Of The Nebraska State Geological Survey And The Morrill Geological Expedition Of 1901, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
IN spite of the phenomenal heat of the summer of 1901, which was of such intensity and duration that active work in the field was finally suspended, enough progress was made to justify the presentation of the matter to this society. It should be reported, first of all, that a request for funds, amounting to twelve hundred dollars, for publishing the first reports of the state geological survey, was presented to the Legislature, and was passed April 1, 1901, without comment or dissent. This may be recorded as the first sum voted by the state for the examination and publication …

Report On The Work Of The Morrill Geological Expeditions Of The University Of Nebraska, Carrie Adeline Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Through the generosity of the Hon. Charles H. Morrill, of Lincoln, the expeditions sent out from the University of Nebraska, known as the Morrill Geological Expeditions, have become a permanent organization of the University. Therefore, it is but a fitting mark of respect that reports of these expeditions be given to the Nebraska Academy of Science from time to time in order that they may become matters of record. Introductory to this work, a private geological excursion was undertaken in June of 1891, by Mr. Erwin Hinckley Barbour in the interest of the University of Nebraska. At this time the …
Glacial Grooves And Striae In Southeastern Nebraska, Erwin Hinckley Barbour
Glacial Grooves And Striae In Southeastern Nebraska, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
NEBRASKA is so close upon the western as well as the southern limit of the drift that evidences of glacial action which might be commonplace elsewhere are rare and interesting here. The mere fact that glacial grooves and striae have been found seems worthy therefore of mention. Glacial drift, readily recognizable as such, does not extend far west of the 97th meridian, and in but one place in the state, on the Dakota-Nebraska boundary, does it reach the 98th meridian. East of the 97th meridian it is distinct and unmistakable, and it may be offered as a safe statement that …
Report On The Initial Work Of The State Geological Survey Of Nebraska, Erwin Hinckley Barbour
Report On The Initial Work Of The State Geological Survey Of Nebraska, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
IN a State such as Nebraska where there is no 'mineral'--a term which in the west has come to mean gold and silver-bearing--it is difficult to convince the masses that there is the least possible economic importance in a State geological survey.
If 'mineral' did occur, apathy could much more easily be overcome, and the appeals for a survey would find more willing and receptive ears. But something stronger than apathy is encountered in the prejudice which has been engendered against a State survey by men who have sought heretofore to establish such for the evident purpose of holding office, …

United States Geological Survey: Publications
SIR :
I have the honor to transmit herewith a manuscript entitled "Wells and Windmills in Nebraska," prepared by Erwin Hinckley Barbour, professor of geology in the University of Nebraska and acting State geologist. The data for this manuscript were obtained by Professor Barbour incidental to his studies of the geology of the State, and have been rounded out by special work carried on under his direction. The original manuscript as prepared consisted of two parts the first upon wells, and the second upon homemade windmills but owing to delays in printing the first part, it has been considered advisable …
The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass
The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass
Graduate Student Theses, Dissertations, & Professional Papers
Since coming to Montana in the spring of 1894 I have spent rnuoh of ay time in studying the lake bed deposits in the western part of the state, and in collecting and studying the vertebrate fossils found in them. These deposits occur in nearly every large valley in the westem part of the state. I have myself observed them in the valleys of the upper Missouri (above the re-rrion of Helena), Gallatin, Madison, Jefferson, Beaverhead, Ruby, Big Hole, Hell Gate, and Bitter Boot rivers, and their tributaries.

Bulletin No. 52 - The Chemical Composition Of Utah Soils (Cache And Sanpete Counties), John A. Widtsoe
UAES Bulletins
The soils of the State [Utah], as found by the Mormon pioneers of 1847, were virgin in the fullest sense of the word. As far as man knows, only a few patches in Southern Utah had ever been cultivated. For untold centuries the atmospheric forces, unhindered by man's intervention, had been allowed to weather and make fit for agricultural purposes the rock fragments that, washed down into the valleys from the mountain ranges, constitute the soils of the State. For a long period, also, long before human tradition begins, there had not been enough water in the Utah valleys to …

UAES Bulletins
According to the last census, 92 1/2 per cent of the Utah farms are irrigated. The advancement of agriculture in this State mainly depends upon the water, the available supply of which, in many of the older settled localities of the State, is already wholly utilized during the irrigation period. The future reclamation of new lands in such localities must, therefore, wait on the development of new sources of supply from storage reservoirs, sub-surface supplies, or from a more economical use of the summer flow of the available streams.

THE PROBLEM OF OUR SOILS AND SOIL MOISTURE.
The soil survey of the state, which was begun by the author in November of 1892, has progressed to the point where it might be considered finished. That is, one or more samples of soils have been taken from every distinct soil region in the state-in fact, most of the separate counties are represented, and mechanical analyses of many of these have already been made. However, in consideration of the size of our counties, the work will not be declared complete until each is represented in the state museum by soil prisms …

A Two-Headed Tortoise, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
INQUIRIES from various quarters have been made so repeatedly for the sequel to the brief story of a young two-headed tortoise, Chrysemys picta, published in the American Journal of Science for October, 1888, that the author is led to believe that a public account thereof will serve more useful ends than many private ones. In order that the sequel may be more intelligible to all, a brief resume of the first paper will be given.
The young tortoise, hatched but a day or so, was found in the marshes bordering West River, New Haven, Conn. The carapace, which was somewhat …

Lincoln Salt Lake And The Occurrence Of Strepsilas Interpres, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Local ornithologists are considerably interested in the occurrence of the Turnstone (Strepsilas interpres) in this State. Three were shot at Lincoln Salt Lake on the 25th of May of this year. These were secured by Mr. W. D. Hunter of the Department of Taxidermy, and were placed by him in the State Museum. This is the first authentically reported occurrence of this bird in Nebraska. So far as we can learn it is not reported for any of our neighboring States.
Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour
Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Dr. Theodor Fuchs, criticises at considerable length the nature of Daemonelix as described by the author, in the University Studies, of the University of Nebraska, Vol. I, No. 4, July, 1892, under the title, 'Notes on a New Order of Gigantic Fossils.' When the criticism first appeared it seemed so fraught with errors that they were counted its own best rebuttal, and no attempt to frame a reply was thought of. However, the author has several times of late been reminded that these errors might pass muster and become fixed in the minds of those, at least, who place too …
Bulletin No. 38 - Preliminary Report On Seepage Water And The Underflow Of Rivers, Samuel Fortier
Bulletin No. 38 - Preliminary Report On Seepage Water And The Underflow Of Rivers, Samuel Fortier
UAES Bulletins
Into a box holding one cubic foot, or seven and one-half gallons of dry sand, one can usually pour from two to three gallons of water without causing any overflow. If the particles of sand were of the same size and cubical in form, they could be packed into a solid mass; and a cubic foot, instead of weighing about 100 pounds--the average weight of dry quartz sand--would then weigh about 165 pounds. But sand grains are irregular in form, and come in contact with adjacent grains only at particular points, thus enclosing spaces or voids, which in dry sand …
