Ecology And Relative Importance Of The Dominants Of Tall-Grass Prairie, J. E. Weaver, T. J. Fitzpatrick Apr 1932

Ecology And Relative Importance Of The Dominants Of Tall-Grass Prairie, J. E. Weaver, T. J. Fitzpatrick

Department of Agronomy and Horticulture: Faculty Publications

This paper is the result of an intensive study of the vegetation of the prairie. The study extended over a period of ten years. It deals with the life histories, distribution, and relative importance of the dominant grasses in a central area of the tall-grass prairie. This area includes the grasslands of the western one-third of Iowa and those of approximately the eastern one-third of Nebraska. On the south it extends into Missouri and Kansas to the Kansas River. North- ward it includes a small portion of southwestern Minnesota and a larger one of southeastern South Dakota.


Indicator Significance Of Brush Lands For The Growth Of Western Yellow Pine, J. E. Weaver Apr 1932

Indicator Significance Of Brush Lands For The Growth Of Western Yellow Pine, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

A study of unusual interest and significance in the application of ecological principles to the solution of an economic problem has recently been completed. It deals with the causes for the absence of western yellow pine in brush vegetation of various types that occur throughout the mountainous portions of northern Utah, eastern Idaho, and western Wyoming, and, in fact, form a much interrupted and fragmented belt whose center extends from the Gulf of California to west-central Montana. Many of these brush sites, especially in northern Utah and southern Idaho, lie immediately below the Douglas fir type (which is continuous) and …

Circular No. 97 - Growing Alfalfa-Seed, John W. Carlson

UAES Circulars

SEED SHOULD BE GROWN FROM SUPERIOR VARIETIES AND STRAINS OF ALFALFA

The present tendency in alfalfa improvement is to establish narrow types or strains for special purposes and which are adapted to a particular set of conditions. It was at one time thought that an alfalfa variety with numerous types of plants would have a wider range of adaptability to diverse conditions and that inter- crossing among the different plants would maintain the vigor of the variety.


Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle Mar 1932

Studies Of Prairie Hay In North Central Nebraska, F. D. Keim, A. L. Frolik, G. W. Beadle

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During five years, 1924-1928, Nebraska ranked first among the states in the production of prairie hay. Approximately 2,500,000 tons were grown annually during this period. In acreage utilized, wild hay ranked third among the field crops of Nebraska. As a forage crop in the state, prairie hay ranked first in acreage, but second to alfalfa in production. The purpose of this bulletin is to report studies made of the botanical structure and yields of the native hay meadows during a period of four years, 1926-1929, in the most prominent prairie hay producing section of the state. Four counties in this …

Selection Cuttings For The Small Forest Owner, Ralph C. Hawley, Allen W. Goodspeed

Yale School of the Environment Bulletin Series

The purpose of this publication is to indicate to owners of small forests methods of harvesting wood and timber and developing future timber crops which .are likely to prove more profitable than those followed in the past. Cutting practices here described have been applied for some years in the Eli Whitney Forest, New Haven, Conn., where forest areas in various stages of treatment can be ·seen.


The Transportation Of Wood In Chutes, Alexander M. Koroleff, Ralph Clement Bryant Jan 1932

The Transportation Of Wood In Chutes, Alexander M. Koroleff, Ralph Clement Bryant

Yale School of the Environment Bulletin Series

Artificial channels, known as chutes, in which logs and bolts may be transported down steep slopes by means of gravity, were devised several centuries ago in the mountainous regions of Europe and later were used by north American loggers, especially in New England, New York, and Pennsylvania. They operate most advantageously on grades that are far in excess of those on which wheeled vehicles or sleds can be used safely, and they are most serviceable for moving timber on terrain which is so steep or broken that the construction cost of suitable roads is prohibitive.


Rb32-270 A Seven Year Study Of A Milk Supply, P.A. Downs Jan 1932

Rb32-270 A Seven Year Study Of A Milk Supply, P.A. Downs

University of Nebraska-Lincoln Extension: Historical Materials

The amount of butter produced by the grain-belt states is evidence that a great many cows are milked by the midwestern farmer. Most of this milk is separated on the farm, the cream is sold, and the skimmilk is fed to hogs and other livestock. As the market for fluid milk has developed, many farmers near the cities have turned to the sale of milk, because it affords a better return for the butterfat sold. Much of the milk produced for sale as fluid milk is produced under practically the same conditions as milk which is produced primarily for the …

Bulletin No. 233 - Observations On The Use Of Commercial Fertilizers On The Arid Soils Of Utah, D. W. Pittman, Clarence Burnham Jan 1932

Bulletin No. 233 - Observations On The Use Of Commercial Fertilizers On The Arid Soils Of Utah, D. W. Pittman, Clarence Burnham

UAES Bulletins

Only within the last few years has the question of commercial fertilizers been worthy of serious consideration in Utah. It has been considered that commercial fertilizers were unnecessary in Utah (1) because arid soils retain their virgin fertility much longer than soils in the humid region which are subject to continual leaching by heavy precipitation, (2) because livestock have always predominated in Utah's agriculture due to the vast areas adapted only to range purposes and livestock means manure to maintain fertility, and (3) because alfalfa, our principal feed crop, is also one of the best plants for gathering nitrogen from …

Ec32-713 The Trench Silo In Nebraska, Ivan D. Wood, E.B. Lewis Jan 1932

Ec32-713 The Trench Silo In Nebraska, Ivan D. Wood, E.B. Lewis

University of Nebraska-Lincoln Extension: Historical Materials

The original idea of using a trench for the storing of ensilage seems to have been the outgrowth of the practice long used in several European countries of storing clover and beet tops in pits. Shortly after the World War, western Canada followed by Montana and North Dakota began to use the trench silo. In Nebraska the true trench silo made its appearance about 1925 or 1926.

The trench silo as described in this circular, unless lined with some permanent material such as brick, concrete or stone, must be considered a temporary structure which will serve for a few years …


The Articulated Skeleton Of Titanotherium, Erwin H. Barbour Jan 1932

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 Jan 1932

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 Jan 1932

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 Jan 1932

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 Jan 1932

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 Jan 1932

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 Jan 1932

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.
