Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert

Nebraska Agricultural Experiment Station: Historical Circulars

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …

A New Giant Camel Gigantocamelus Fricki, Gen. Et Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

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

A lower Pleistocene deposit containing fossil vertebrates near Broadwater, Morrill county, Nebraska, has been reported upon by the writers, beginning three years ago. Five fossil quarries have been opened since the site was discovered in 1936.

The White River Oligocene Rodent Diplolophus, Erwin Hinckley Barbour, Thompson M. Stout

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

The rich and varied nature of the mammalian faunas of the White River Oligocene has been recognized for many years, but the exact geologic succession is only now becoming known. In these faunal assemblages the rodents and lagomorphs appear to have been important elements, perhaps numerically as abundant in the Oligocene as are these same groups at present.

Report Of Progress Of The Nebraska State Museum, Erwin H. Barbour

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

The history and development of the Nebraska State Museum since 1891 have been summarized in a preliminary manner up to 1925 in the first number of Volume I of the Bulletin of the Nebraska State Museum.1 Since 1927, the collections of the Nebraska State Museum, The University of Nebraska, have been housed in a new building, Morrill Hall, on the city campus of The University of Nebraska. It now seems fitting to report upon the exceptional progress of the past few years, and to acknowledge the fine cooperation of those who have helped to make it possible.

The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata

Harold W. Manter Laboratory of Parasitology: Library Materials

Gizzard-worms of poultry, Cheiloapirura hamulosa, are nematodes occurring in the gizzards of chickens and turkeys.

Summary and Conclusions

Previous to this report the carriers for the gizzard-worm in Hawaii were unknown. Recent investigations by the writer have shown that the flour beetle, Tenebroides nana, and the sand hopper, Orchestia platensis, collected from poultry farms in the Territory of Hawaii have been found naturally infested with the infective larvae of the poultry gizzard-worm, Cheilospirura hamulosa. Out of 8 laboratory-raised chickens to which there were fed about 2,300 grasshoppers that had been collected in an endemic gizzard-worm area, …

Palaeontologic And Geologic Consideration Of Early Man In Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz

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

There has been much discussion recently relative to the geologic age of Yuma and Folsom artifacts. The writers submit the following palaeontological and geological data which may aid in a better interpretation of the subject. This paper deals with three localities in Nebraska where Yuma and Folsom implements have been found with extinct mammals; namely, the Scottsbluff Bison Quarry, the Sand Hill blow-out sites, and the Sioux County artifact sites.

A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The following key to the Nebraska cutworms and armyworms injurious to corn is based upon structural characters supplemented in some instances by color. Not all of the species in this key have been found in Nebraska; some are included because they are to be found in near-by states to such an extent that they probably are present in this state.

A New Fossil Peccary, Prosthennops Niobrarensis, From Brown County, Nebraska, Edwin H. Colbert

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

During the summer of 1929, the writer, accompanied by Mr. Paul O. McGrew of the University of Nebraska, discovered during the course of excavations for fossil vertebrates in northern Brown County, Nebraska, a fairly complete peccary skull referable to the genus Prosthennops. This skull, due to its several unusual characters, as well as to its fair degree of completeness, would seem to warrant a special and a rather detailed description. Consequently the specimen has been kindly turned over to me by Dr. E. H. Barbour, Director of the Nebraska State Museum, not only for the purpose of the present …

A New Miocene Dog, Mesocyon Geringensis, Sp. Nov., Erwin Hinckley Barbour, C. Bertrand Schultz

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

A field party from the Nebraska State Museum consisting of Messrs. E. L. Blue, Frank Crabill, Loren Eiseley, and C. Bertrand Schultz, on August 28, 1931, was fortunate in finding the remains of a new Mesocyon. This specimen, number 4-28-8-31, the Nebraska State Museum, was found in the Gering formation (lower Miocene), fifteen feet above the Brule, 400 feet west of the road in Redington Gap, near the center of the S. 1/2, sec. 14, T. 19 N., R. 52 W., west of Bridgeport, Morrill County, Nebraska.

Gnathabelodon Thorpei, Gen. Et Sp. Nov. A New Mud-Grubbing Mastodon, Erwin Hinckley Barbour, George F. Sternberg

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

In February, 1932, while opening a gravel pit to get material for highway construction, the skull, tusks, and mandible of a new longirostral mastodont were found by Robert Arnold on his ranch, Sec. 24, T. 12 S., R. 22 W., 1 1/2 miles due east of Ogallah, Trego County, western Kansas. This point is located about 20 miles west and three miles north of Hays, the seat of the Fort Hays Kansas State College, in the museum of which the above mentioned specimen is mounted and exhibited. When unexpectedly exposed by Mr. Arnold and his associates, the great skull was …

A New Giant Camel, Titanotylopus Nebraskensis, Gen. Et Sp. Nov., Erwin H. Barbour, C. Bertrand Schultz

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

The purpose of this bulletin is to figure and describe a .amel brought to light in the field season of 1933, which seems to be the giant of all camels found in the State. The specimen consists of the right ramus with the symphysial portion. The mandible is 26% inches long, or about the length of one's outstretched arm to the finger tips. This jaw is nine inches longer than that of Camelops kansanus. Such an extraordinary jaw indicates a camel nearly twice as large as Alticamelus altus. In reference to its unusual size we are proposing for it the …

A New Rhinoceros Mount, Trigonias Osborni, Erwin H. Barbour

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

On February 9, 1934, a pair of rhinoceroses, Trigonias osborni, was installed in the Founder's Room in Morrill Hall, the Nebraska State Museum. They are figured and accorded brief consideration here in order to maintain the printed records of such acquisitions in the Nebraska State Museum. The two skeletons, carefully posed, were put in the south wall case to be associated with a pair of Diceratherium from Morrill County. and the mounted skeletons of two Brown County Te leo ceras. In this gallery two long built-in wall cases insure ample facilities for the proper installation of six rhinoceroses, for each …

A New Ovibovine, Symbos Convexifrons, Sp. Nov., Erwin H. Barbour

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

In Bulletin 25, entitled The Musk-oxen of Nebraska, the writer figured and briefly catalogued the ovibovines of this State as known at that date. In the meantime an interesting new form unlike that of any species falling within our experience presents itself from the Pleistocene of Cherry County, Nebraska. The new specimen cannot be assigned a place in any of the four following genera: Preptoceras, Euceratherium, Ovibos, or Bootherium, but may possibly be referable to the genus Symbos, to which we are assigning it provisionally. It is so unlike Symbos, however, that it may be a distinct genus. …

The Nebraska Meteor And Meteorite Of August 8, 1933, Erwin Hinckley Barbour, C. Bertrand Schultz

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

At approximately 10:30 a. m., mountain standard time, on August 8, 1933, a large meteor, traveling in a westerly direction, exploded over the panhandle of Nebraska. The phenomenon was witnessed by many citizens throughout the region, and by a number of students from the University of Nebraska, who were engaged at the time in palaeontological field work in northwestern Nebraska .

A Mounted Skeleton Of Megabelodon Lulli, Erwin Hinckley Barbour

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

A skeleton of Megabelodon lulli, partly composite, was mounted in the laboratory May 31, 1933, and was formally installed and placed on exhibition in Elephant Hall, June 7, 1933.

The Geology And Mammalian Fauna Of The Pleistocene Of Nebraska Part I Outline Of Pleistocene Geology Of Nebraska Part Ii The Pleistocene Mammals Of Nebraska, A. L. Lugn, C. Bertrand Schultz

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

The object of the present paper is to provide a suitable brief statement of the present state of knowledge of the Pleistocene geology of Nebraska, for an adequate understanding of the Pleistocene Mammal list, by Mr. C. Bertrand Schultz, which forms Part II of this report. The "outline" is necessarily brief and does not contain many detailed sections, nor lengthy discussions of controversial points. It is lacking in adequate detailed descriptions of new formations and may not be entirely convincing to many readers. The only excuse which the writer can offer for the shortcomings of the following pages is the …

The Articulated Skeleton Of Titanotherium, Erwin H. Barbour

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

The skeleton of a titanotherium, stored since 1894, was installed in the west corridor of Morrill Hall, April 28, 1931. In the meantime the specimen has been visited by many citizens, women's clubs, and especially by delegations of school children, boy scouts, and like organizations, from various parts of the State and elsewhere. Repeated requests for a popular report on this particular specimen actuates the writing of this leaflet. Titanotheres were by far the largest creatures of Oligocene time in Nebraska. In point of size they are called gigantic, elephantine, and titanic. The titans of Greek mythology were giants, and …

The Scottsbluff Bison Quarry And Its Artifacts, Erwin Hinckley Barbour, C. Bertrand Schultz

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

The association of artifacts with extinct bison bones in a quarry near Grand Island, Hall County Nebraska,¹ and from one in Custer County, Nebraska, have already been reported.² In the meantime, continued search has been rewarded, and a large bed of fossil bison with associated flint implements found. The discovery, if not of actual consequence, at least adds something to the accumulating evidence that Pleistocene man in America may have been a reality.

Association Of Artifacts And Extinct Mammals In Nebraska, Bertrand Schultz

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

During the past four years the Nebraska State Museum, under the directorship of Dr. Erwin Hinckley Barbour, has been making even more extensive palaeontological collections throughout Nebraska than heretofore. As work progresses, especially with fossil bison and mammoth, there is increasing evidence that man appeared in Nebraska much earlier than is generally believed. Two occurrences of artifacts associated with fossil bones will constitute the main theme of this paper.

The Mounted Skeleton Of Bison Occidentalis, And Associated Dart-Points, Erwin Hinckley Barbour, C. Bertrand Schultz

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

A composite skeleton of Bison occidentalis was mounted and installed in its case on the lower floor of Morrill Hall, on April 22, 1932. The skeleton in itself is attractive because of its size and excellent preservation, and is rendered additionally interesting by two dart-points, one found under the scapula, and the other under the ribs.

A New Oreodont Slab, Erwin Hinckley Barbour, C. Bertrand Schultz

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

A slab of pale, reddish-brown sandstone, exhibiting the articulated skeletons of two oreodonts, has been placed on display in the west corridor on the first floor of Morrill Hall. Apparently, a female and well-grown young one lay down together and perished, perhaps from disease, or from chilling winds. They must have been buried quickly, for all of the bones are present, are in perfect condition, and are in articulation, especially in the old one. In the adult the articulation is complete from the ungual phalanges of the two forefeet to the terminal caudal, even though in the figure the skeleton …

The Mandible Of Platybeldon Barnumbrowni, Erwin Hinckley Barbour

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

Platybelodon barnumbrowni was described originally as Torynobelodon barnumbrowni.¹ The Nebraska State Museum was visited and this unique specimen studied by Dr. Henry Fairfield Osborn and Dr. Walter Granger, August seventeenth and eighteenth, nineteen hundred and thirty-two. It is the opinion of both that this specimen belongs properly to their Mongolian genus Platybelodon. With certain reservations the writer wishes to defer instantly to their judgment, which is based on unequalled experience. It is perfectly apparent that this form makes a close approach to the remarkable Platybelodons found by Granger and Andrews in the Gobi Desert of Mongolia, later figured and …

The Skull And Mandible Of Mastodon Moodiei, Erwin Hinckley Barbour

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

The mandible of the Milford mastodon, Mastodon moodiei, was figured and described in Bulletin 24, December, 1931. In the meantime, the fragments of both skull and mandible have been properly cleaned, put together, and mounted for exhibition. No essential parts of the skull or mandible are wanting or are seriously damaged.

The Articulated Skeleton Of Eubelodon Morrilli, Erwin Hinckley Barbour

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

The mounted sketleton of Eubelodon morrilli was installed in the west wall case of Elephant Hall December 31, 1931, and has attracted the attention and favorable comments of citizens and other guests. It should be explained that the case in which it is displayed is ten feet deep, sixteen feet high, and extends the length of the hall. Altogether it is a large and impressive mount which reflects credit upon its preparators, and is an important and instructive addition to the Morrill Palaeontological Collections. The pose is spirited and interesting, and the action is all that can be expected of …

Association Of An Arrow Point With Bison Occidentals In Nebraska, F. G. Meserve, Erwin H. Barbour

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

Of late, anthropological literature relative to the association of man and extinct mammals, especially bison and mammoth, has received many contributions from various and widely separated sources. Naturally the question has arisen whether man's advent in America is somewhat earlier than has been generally admitted, or whether certain extinct animals have persisted longer than has been realized. The issue is one of such importance and interest that even minor contributions seem desirable. It is well understood by all that the evidence, when submitted, will be properly weighed, and that conservative judges may rule out much or all of the testimony. …

The American Mastodon With Mandibular Tusks, Erwin H. Barbour

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

Mastodons and mammoths, represented by their relics, are so frequently exposed by shovel, plow, road grader, dredge, and rains, that they have become household words. They are plainly the commonest and best-known vertebrate fossils. They were fortuitously entombed, and are now accidently found. Their relics, though numerous, never represent the grand total that lived. Indeed, it was a rare individual that fell where circumstances favored rapid interment and consequent preservation; the grand majority fell in the open where their bones suffered rapid and complete decay. The American mastodon occupies a position between the long-jawed, long-skulled, four-tusked ancestor called Palaeomastodon, and …

Infection Experiments With Spindle Tuber And Unmottled Curly Dwarf Of The Potato, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is probable that more than one insect species are capable of spreading some of the potato virus diseases. This conclusion was also indicated by repeated observations in the dry-land section of western Nebraska. While aphids are abundant and are probably the chief vectors of potato virus diseases in the more humid sections of the country, they are usually scarce in the western upland plains area and are not present in large enough numbers to account for the rapid spread of spindle tuber and unmottled curly dwarf which sometimes occurs. It was therefore considered advisable to determine the common potato …

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, …
