Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska¹. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.

Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour

Conservation and Survey Division

ln southern Harlan and Franklin counties, there occur many acres of green quartzite which must be of commercial consequence when made available. It is a neglected resource upon which important industries are sure to be based. With the development of this bed in view, the Nebraska Geological Survey has examined this area. and through this leaflet wishes to place the results before possible investors.

A New Saber-Toothed Cat From Nebraska, Erwin H. Barbour, Harold J. Cook

Conservation and Survey Division

During the field season of 1913, while exploring the Pliocene beds of Brown County, Mr. A. C. Whitford, a Fellow in the Department of Geology, University of Nebraska, discovered the mandible of a new machaerodont cat. His work in this region was in the interest of the Nebraska Geological Survey and the Morrill Geological Expeditions.¹

Bulletin No. 134 - The Nitric Nitrogen Content In The Country Rock, Robert Stewart, William Peterson

UAES Bulletins

In many arid sections of Western America there have been reported marked accumulations of nitrates in the cultivated soil. Hilgard,(1) who was the first to observe these accumulations, believed that the nitrates are being formed at the present time by the rapid nitrification of the organic matter contained in the soil. In Colorado there has been considerable trouble with orchards dying; the death of the trees in some cases has been attributed to the excessive accumulations of nitrates in the cultivated soil. These accumulations are due, according to Dr. Headden,(2) to the fixation of atmospheric nitrogen by bacteria now at …

Plant Tissue In The Carboniferous Shales Of Nebraska, Erwin H. Barbour

Conservation and Survey Division

While exploring the newly discovered Eurypterid beds,¹ just one mile south of Peru, Nebraska. November 8, 1912, the writer found unusual amounts of actual plant tissue of Carboniferous age. It seems incredible that it should have been preserved through such a lapse of time. Only the most resistant tissue could have endured. When freshly cleaved, the Eurypterid shales reveal innumerable bits and patches of it, mostly bright red in color.

Notice Of Jelly Fishes In The Carboniferous Of Nebraska, Medusina Walcotti, Erwin H. Barbour

Conservation and Survey Division

In visiting the quarries of the State, certain quadripartite objects suggesting the form of jelly fishes have long attracted the writer's attention. They are large and coarse, and were assumed to be imitative concretions. However, the total number observed seems to strengthen the probability that they are of organic origin. In the fall of 1913, while conducting a field class through the Burlington Quarries, located about two miles northwest of South Bend, they were noted again in a new locality, and three specimens were obtained. Two of these were unusual examples, and showed sufficient structure to identify them with the …

Two New Fossil Dogs Of The Genus Cynarctus From Nebraska, Erwin H. Barbour, Harold J. Cook

Conservation and Survey Division

The genus Cynarctus was founded by Dr. W. D. Matthew on a nearly complete pair of lower jaws from the Pawnee Creek Beds (Middle Miocene) of Colorado, found in 1901. Since that time no new material pertaining to this genus has been reported. Dr. Matthew referred the genus to the subfamily Amphicyoninae, and to a position intermediate between the primitive bear Ursavus, and the Canidae, with primitive characters retained from its Oligocene ancestors.

A New Longisrostral Mastodon From Cherry County, Nebraska, Erwin H. Barbour

Conservation and Survey Division

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. Nevertheless some interesting and valuable material was obtained by the Nebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

A New Longisrostral Mastodon From Cherry County, Nebraska, E. H. Barbour

Conservation and Survey Division

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. N evertheless some interesting and valuable material was obtained by the N ebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

The mastodon constituting the basis of this paper was found in the exposnres bordering the Snake River in section 33, range 30 west, and township 32 north. The talus slope was strewn with fragments of the tusk and bone of a mastodon. This led the …
