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 …

The Musk-Oxen Of Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The remains of no less than eight fossil musk-oxen are already known in Nebraska, of which one is preserved in the Museum at Hastings, Nebraska, and seven in the State Museum at Lincoln. This is a large number to be recorded in anyone state. As late as 1891 authors wrote that but two examples of musk-oxen were known in the United States, one from Kentucky, and one from Arkansas, if, indeed, they be valid species. Now that pioneer days are well behind this commonwealth, and that there is a growing sentiment for exploration and proper display of the State's resources, …

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. …

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 …

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 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 …

Ec31-625 How To Produce Better Milk And Cream, E.L. Reichart

University of Nebraska-Lincoln Extension: Historical Materials

Would you not be glad to have people refer to your county as the best dairy county in Nebraska?

Of course you would because it would bring more cattle buyers into your community and you would get better prices for your bull and heifer calves.

You can accomplsih all these things by producing higher grade milk and cream. Perhaps the suggestions on the next few pages will …

Rb31-258 The Contribution Fo Nebraska Farm Women To Family Income Through Poultry And Dairy Products, M. Ruth Clark

University of Nebraska-Lincoln Extension: Historical Materials

This investigation was made in 1929-1930 for the purpose of studying the activities of Nebraska farm women in the raising of poultry and in the care of dairy products, to discover whether or not such activities resulted in a contribution to the family income. With this in view, a group of women were asked to keep records for one year (from April 1, 1929 to March 31, 1930) of the value and amount of dairy and poultry products sold or used, of all expense incurred in production, and of the time spent both by the homemaker herself and by all …

Studies In The Life History Of The Croton Bug, Blatella Germanica (Linnaeus), Laurence Adams Carruth

Electronic Theses and Dissertations

The Croton bug, or German Roach as it is commonly called, has been widely known for centuries. In the past, a considerable amount of work was done in attempting to find methods of controlling this insect, but relatively little attention was given to a study of its morphology, time of development, or to the finer details of the life history. this lack of information is probably due, in part to the fact that there are several similar common species of roaches and also because the Croton bug has probably received less attention than the other roaches, at least from a …

The Effect Of A Varying Moisture Supply At Different Periods Of Growth On The Development, Yield And Quality Of Flax, William K. Soule

Electronic Theses and Dissertations

In the flaxseed producing section of the United States consisting of the states of North Dakota, South Dakota, and Minnesota and Montana, periods of drought frequently occur during some part of the growing season.

Greenhouse Studies On The Relationship Of Age Of Wheat Plants To Infection By Puccinia Graminis Tritici, George W. Eade

Electronic Theses and Dissertations

The resistance of wheat to the stem-rust organism (Puccinia graminis tritei) has been under investigation for a number of years. Although rust resistance has been investigated from various angles, there still remains a question as to the nature of resistance, the time when resistance first appears in plants and whether or not it is of a stable character. Peltier found that environmental conditions could change the degree and type of stem rust infection on wheat plants; Miss Hart proved that stomatal behavior was very important in the rust resistance, and Harrington and Aamodt studied the inheritance of rust resistance and …

The Spleen Considered With Special Reference To Its Functions, Louis J. Schmidt

Bachelors’ Theses

In arranging this thesis an attempt has been made to show that by virtue of its embryology, anatomy and histology, the spleen is the better enabled to carry out its alleged functions. The discussion here presented is confined to a story of the functions of the mammalian spleen alone. The similarities in the reactions of the spleen in the various mammalia is quite evident. Experimentation and observations were carried out on the lower mammalia while only the reactions of the splenectomized humans could be observed.

The Spleen: With Special Reference To Its Origin And Comparative Morphology, Morris Aaron Gilbert

Bachelors’ Theses

Throughout the ages the spleen has been an object of the most active curiosity. The opinion that the spleen is unnecessary and of no use to the individual has prevailed with an uninterrupted succession in the World in all ages. In Persia, many centuries ago, in the reign of Abouserous it was a custom to splenectomize the horses that were kept to carry the King’s dispatches, in order to give them more agility and swifter feet. The great Aristotle thought the spleen to be a sort of spurious liver planted in the left side to correspond to the liver in …

The Spleen Considered With Special Reference To Its Physiology As Determined Mainly From Splenectomy, Frank X. Schuler

Bachelors’ Theses

The spleen is essentially a vertebrate organ and its steady persistence throughout the group is an indication of its importance. Comparative study shows that it has certain common structural features , which may be counted fundamental or essential. In some animals, for example, in mammals, there are found additional structures, notably lymphoid tissue and splenic muscle often regarded as secondary acquisitions.

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.
