The Milford Mastodon, Mastodon Moodie I, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour
The Milford Mastodon, Mastodon Moodie I, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
In developing the hydro-electric plant of the Iowa and Nebraska Light and Power Company, a number of dams were thrown across the Blue River and its branches. One of these, known as Dam No.7, was built across the West Blue, about nine miles southwest of Milford, Seward county, Nebraska. This dam raised the water well above the ordinary river level, and flooded fifteen or twenty acres of valley land. The impounded water soaked into, and washed against, the base of a twenty-foot bank of cross-bedded sand, until some time during the winter of 1931, a portion of the bank near …
A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour
A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
In the accompanying cut the array of great tusks outlined through their rough crates may lack attractiveness, nevertheless the assemblage is quite out of the ordinary, and seems worth recording in bulletin form. In all museums, and like institutions, freight and express deliveries are matters of daily routine; however, the morning's freight shown in the cut is unique. Herein is represented the more showy portion of the proboscidean freight received at the Nebraska State Museum in a single consignment, in the field season of 1930. The other boxes of mammoth skulls, jaws, and bones, received at the same time, are …

A New Amebelodont, Torynobelodon Barnumbrowni, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The subfamily of longirostrine mastodonts known as the Amebelodontinae have been so recently discovered and described that as yet they; are little known by the citizens of this state. They are most briefly and directly described as shovel-tusked mastodons. The first one found, namely Amebelodon fricki, was secured in April 1927, and was published June 1927. In the meantime, many other examples of Amebelodonts have been added to the Morrill Palaeontological Collections of the Nebraska State Museum. The exact number cannot be stated until the material shipped in from the field during the current season is unpacked, cleaned, and identified. …
The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour
The Giant Beaver, Castoroides, And The Common Beaver, Castor, In Nebraska, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Respecting the giant beaver, Castoroides, in Nebraska, four occurrences can be reported. Of rodents in general the dawn. was in the early Eocene, at which time there were in existence certain squirrel-like members of the order. Rodents are a persistent group, and are among the smallest, most distinctive, most numerous and widely distributed orders of terrestrial mammals. No other order boasts of so many species, the number being between nine hundred and one thousand. In spite of wide divergencies and modifications adapting them to various modes of life, such as climbing, burrowing, swimming, flying, leaping, and running, there is remarkable …
A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour
A New Crinoid Slab, A Bit Of Mississipian Sea Bottom, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Crinoids are popularly known as stone-lilies, featherstars, and sea-lilies. The word lily is a misnomer, and many, misled by the name and by the lily-like form, associate crinoids with the plant kingdom. The name, feather-star, seems explicit for it refers to the feathery arms surrounding the cup or calyx, and expresses relationship to the starfishes and their kind. The cup is attached to a stem, and the stem is anchored to the ocean floor by so-called roots, which are really hold-fasts, or anchors. These features may be seen in the diagram at the end.
Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour
Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Nebraska has long been a collecting ground famous for its fossil mammals, but as yet no dinosaurian bones have been reported, nor have they been expected. The distal end of a finely preserved femur, however, has recently been brought to light, supposedly occurring in position in the Dakota formation of eastern Nebraska. It was discovered, collected, and donated by Mr. J. B. White, (University of Nebraska, Law, class of 1899) on his farm two miles south of Decatur, in northeastern Burt County, near the Missouri River. It was found in undoubted Dakota sand associated with many leaf impressions. This is …

Most of the field work has been conducted at the Aleza Lake Forest Experiment Station, in the valley of the Upper Fraser River, near the city of Prince George [British Columbia].
I. A series of twelve permanent plots (numbers 1 to 12) was established for the purpose of studying the occurrence of natural reproduction on various types of seed bed, under different densities of overwood and on northern and southern aspects. 2. A second series of four plots (numbers 17 to 20) was laid out in logged-off land for the purpose of studying the survival and growth of advance reproduction …
Amebelodon Sinclairi Sp Nov., Erwin H. Barbour
Amebelodon Sinclairi Sp Nov., Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
Amebelodonts are so new and so rare that even fragmentary facts relative to the group seem worth publishing. The specimen under consideration is a mandibular tusk found on the farm of Mr. A. S. Keith, Freedom, Frontier County, Nebraska, on the Morrill Geological Expedition of 1928, and is numbered 1-17-7-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. The formation was Late Pliocene or Pleistocene.
The Mandible Of Amebelodon Fricki, Erwin H. Barbour
The Mandible Of Amebelodon Fricki, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The type specimen of the genus Amebelodon is installed in the Nebraska State Museum, the University of Nebraska, Lincoln. It consists of a mandible with tusks and teeth, all of which are dense and perfect, barring minor cracks and breaks. One toe bone and part of a rib found associated with this mandible may belong to this animal. It was discovered by Mr. A. S. Keith on his farm near Freedom, Frontier County, Nebraska; was secured for the palaeontological collections of Hon. Charles H. Morrill by Mr. Phillip Orr, April 4, 1927; was briefly described and figured in a Museum …

Scholasticism An Intellectual Basis And Unifying Principle Of Modern Science, Alice V. Johnson
Electronic Theses and Dissertations
Amid the almost uninterrupted disintegration of systems during the last three centuries, the philosophy of St. Thomas has alone been able to stand the shock of criticism; it alone has proved sufficiently solid and comprehensive to serve as an intellectual basis and unifying principle for all the new facts and phenomena brought to light by modern science.

Torynobelodon Loomisi, Gen Et. Sp. Nov., Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The group of proboscideans which we have called the shovel-tuskers or Amebelodonts, was announced in June, 1927,1 following the discovery of Amebelodon fricki. In the field season of 1928, two additional species were found which are represented by mandibular tusks. One of these is a tip of a large and unique tusk, numbered 2-3-9-28, S. and L., the collectors being Bertrand Schultz and John LeMar, both of the class of 1931, the University of Nebraska. It was found within 200 to 300 yards of the spot on his farm where Mr. A. S. Keith, Freedom, Frontier County, Nebraska, found …
The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour
The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
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 …

Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig
Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig
Yale School of the Environment Bulletin Series
This paper presents a study of the correlation between soil colloidal content and soil productiveness and hence a measure of the value of colloidal content in determining site quality. The character of this investigation also permitted incidental observation and comment on the relative value of organic matter, soil acidity, and soil type and class as similar measures. The findings are directly applicable to the forest soils of southern Connecticut and, more particularly, to such of these soils as occur commonly in the vicinity of New Haven. Since these soils are typical of the brown, weakly podsolized forest soils of southern …
Some Aspects Of Soil Moisture In The Forest, Ian J. Craib
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.

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 (1924–2023)
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.
Archidiskodon Maibeni, Erwin H. Barbour
Archidiskodon Maibeni, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
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.

Prosthennops Xiphodonticus, Sp. Nov.: A New Fossil Peccary From Nebraska, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
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 (1924–2023)
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 …

Hackberry Conglomerate A New Nebraska Rock, Erwin Hinckey Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
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.

Elephas Scotti A New Primitive Mammoth From Nebraska, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
On February 18,1922, the mandible of an unusually primitive mammoth was secured for the palaeontological collections of Mr. Hector Maiben by Mr. E. T. Engle. The specimen was found in Aftonian gravel on the farm of Mr. E. J. Hartman, five miles south of Staplehurst, Seward County, Nebraska. It is numbered 18-2-22 in the accession book of the Nebraska State' Museum.
Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson
Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson
Bulletin of the University of Nebraska State Museum (1924–2023)
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
Skeletal Parts Of The Columbian Mammoth Elephas Maibeni, Sp. Nov., Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
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.
Notes On Nebraska Fulgurites, Erwin Hinckley Barbour
Notes On Nebraska Fulgurites, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
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.
