Review Of The Phytogeography Of Nebraska. 1. General Survey, By Roscoe Pound, Elizabeth Britton
Review Of The Phytogeography Of Nebraska. 1. General Survey, By Roscoe Pound, Elizabeth Britton
School of Biological Sciences: Faculty Publications
From the preface we learn that this work is the result of nearly five years of active study of the floral covering of Nebraska, carried on by the members of the Botanical Seminar in the Botanical Survey of the State. The systematic study of the vegetation of Nebraska was begun by Dr. Bessey in 1884, and has since been carried on by him and his students, all previous collecting having been more or less desultory and unreliable. The Botanical Survey was organized in 1892, and its work has been directed to the collecting of specimens and observations for a series …
The Vegetation Regions Of The Prairie Province, Roscoe Pound, Frederic Clements
The Vegetation Regions Of The Prairie Province, Roscoe Pound, Frederic Clements
School of Biological Sciences: Faculty Publications
The vegetative covering of the North American continent falls naturally into two great areas, forest and plain. At first thought it would seem that these were primary phytogeographical divisions, but a comparison with the vegetative covering of other continents proves the contrary. Considered as a phytogeographical feature, the North American forested area is an entity ; from a floristic or formational standpoint, it may be analyzed into several distinct portions of widely separated relationship. The ground-tone of the great bulk of the North American forests is that of the forests of British North America, which are closely related to those …
A Preliminary Report On Experiments With Forage Crops, T. L. Lyon
A Preliminary Report On Experiments With Forage Crops, T. L. Lyon
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A preliminary report on experiments with forage crops. Covers sorghum, cow pea, hairy vetch, Canada field pea, non-saccharine sorghums, soybean, and rye.
Summary
Permanent grass pastures may be successfully substituted by certain annual forage plants.
A quick-growing variety of sorghum affords pasture fully equal to native or cultivated grasses.
Sorghum has the advantage of affording more forage per acre, and in being green and succulent throughout the entire summer. Its disadvantage consists in the necessity of plowing land for each crop.
One acre of sorghum will furnish pasture for ten cows twelve days.
The most profitable time to pasture sorghum …

Oo-Mah-Ha Ta-Wa-Tha (Omaha City), Fannie Reed Giffen, Susette La Flesche Tibbles, Judi M. Gaiashkibos
Electronic Texts in American Studies
“This little book tells many important tribal stories for today and for future generations. These historic vignettes of the Omaha Nation and its leaders are shared so personally by author Fannie Reed Giffen and her collaborators, Susette and Susan La Flesche. It has been a treasure of mine for 25 years and I hope it becomes one of yours.
The re-publication of the original comes on the 125-year anniversary of the 1898 Omaha Trans-Mississippi Exposition and Indian Congress. Its arrival is timely as many of its stories and people are vital to our nation’s history. A sculpture of Omaha Chief …
Phylogeny And Taxonomy Of The Angiosperms, Charles E. Bessey
Phylogeny And Taxonomy Of The Angiosperms, Charles E. Bessey
Papers in Systematics and Biological Diversity
It is unnecessary for me to state at the outset what is evident to every botanist, that it is as yet impossible to present a complete phylogeny of the angiosperms. Phytopaleontology is too young a science, and the materials with which it deals are yet far too scanty to have given us direct evidence as to the phylogeny of all families of plants. No one can trace with great certainty from the fossil remains of plants yet discovered the genealogy of any considerable portion of the vegetable kingdom. It will be many a year before the direct evidence we so …
Zoology In The High School Curriculum, Henry B. Ward
Zoology In The High School Curriculum, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
A long time has elapsed since Bacon gave to the world the sound advice that “ we should accustom ourselves to things themselves.” Little by little this idea has gained ground, until now it is recognized as a general principle in every grade of educational work and in widely separated departments of study that contact with concrete objects is far more inspiring and thought-producing than the mere scanning of black marks on a white page. So far as natural science is concerned, the varied training which it affords has been abundantly discussed before this association and elsewhere. To be sure, …
The Heaven Of The Bible, Ida C. Craddock, Paul Royster , Editor
The Heaven Of The Bible, Ida C. Craddock, Paul Royster , Editor
Zea E-Books in American Studies
This remarkable and unconventional description of the Christians’ afterlife in the New Jerusalem is based on Ida Craddock’s strict interpretation of Bible passages (from Ezekiel, Elijah, Daniel, and John) that describe the heavenly city and on the words of Jesus relating to life after the Resurrection. She advances scriptural arguments to show that Heaven is a substantial place where the inhabitants with physical bodies eat, drink, work, defecate, have sexual relations, and go naked.
“The idea, all too prevalent among Christian people, that Heaven is ethereal, unsubstantial, and intangible, with little or no likeness to earth and the earthly life, …
A Biological Examination Of Lake Michigan In The Traverse Bay Region, Henry B. Ward
A Biological Examination Of Lake Michigan In The Traverse Bay Region, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
During the summer of 1893 the Michigan Fish Commission entered upon a biological study of the Great Lakes by maintaining a party on Lake St. Clair. In the report of that two months, written by the director of the laboratory, Professor J. E. Reighard, are given in full the reasons which led to the inception of the undertaking and the aims which its promoters held in view. A study of the life of the lake in all its manifold interrelations and especially of those factors which bore upon the welfare of the food fishes in general and the young whitefish …

The Plant-Geography Of Germany, Roscoe Pound
The Plant-Geography Of Germany, Roscoe Pound
School of Biological Sciences: Faculty Publications
In a recently published address Dr. Coulter speaks of a new movement in botany which is sending botanists " to the great laboratory of nature," and replacing collecting trips by biological surveys. "The old-fashioned collection of plants," he says, "will hold no more relation to the new field work than the old geology, with its scattered collection of fossils, holds to the topographic geology of to-day." Geographical botany as it is now understood is comparatively a recent development. Collectors and cataloguers for a long time have been gathering a portion of the bare facts upon which geographical botany must proceed, …

THE PROBLEM OF OUR SOILS AND SOIL MOISTURE.
The soil survey of the state, which was begun by the author in November of 1892, has progressed to the point where it might be considered finished. That is, one or more samples of soils have been taken from every distinct soil region in the state-in fact, most of the separate counties are represented, and mechanical analyses of many of these have already been made. However, in consideration of the size of our counties, the work will not be declared complete until each is represented in the state museum by soil prisms …

The Food Supply Of The Great Lakes; And Some Experiments On Its Amount And Distribution, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
The subject of agriculture has received for many years the closest attention of scientific workers. Not only the character of the different products, their food value for different uses and in connection with the raising of different kinds of stock ; but also the value of the soil, the use of each element in it, the exact relation of each individual particle in the entire chain of biological relations from the unorganized matter to the saleable beef or pork, has received from the experiment stations of the country the most careful study. Every one of the pests, of the enemies …

Flora Of Nebraska: Part 21. Rosales, Per Axel Rydberg, The Botanical Seminar, University Of Nebraska
School of Biological Sciences: Faculty Publications
DeCandolle, the author of Calyciflorae, gives the following characters (Prodromus, 2: 1): “Calyx gamosepalous, that is, the sepals more or less united at the base. Torus more or less adnate to the bottom of. the calyx. Petals and stamens inserted on a torus which is partly adnate to the calyx, and therefore geuerally said to be borne on the calyx. Petals free or united with each other. Ovary free, or adnate to the calyx.”
What has generally been regarded as the lower portion of the gamosepalous calyx, and is described as such in many recent systematic works, is in reality …
The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward
The Parasitic Worms Of Man And The Domestic Animals, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
This article has been written for the general information of those engaged either on a large or on a small scale in stock raising in our own state particularly, and, while not intended to be a complete treatise on the subject, it includes references to those parasites which seem to be the most important or most likely to be found within our borders. The parasites of cattle, sheep, horse, hog, dog, cat, and man, which have many species in common, form the subject of this paper. The parasites of domestic fowl are, however, quite different from those considered here and …
The Food Supply Of The Fish In The Great Lakes, Henry B. Ward
The Food Supply Of The Fish In The Great Lakes, Henry B. Ward
Studies from the University of Nebraska Zoological Laboratory
When the early settlers made their homes along the shores of the Great Lakes, the waters of these inland seas teemed with fish. A cheap and apparently inexhaustible supply of food lay within easy reach, and they drew from it unstinted, nor was it strange that, with the increasing population and ever-widening means of communication, delicacies so tempting as the whitefish and lake trout were eagerly sought after in the markets of the neighboring cities, and that the ingenuity of generations of fishing folk was taxed to invent means of securing the fish-until finally, in the face of a growing …

The Vegetable Kingdom is in other words the plant world, or the aggregate of organisms called plants. It is co-ordinate with the animal kingdom, and these two include all forms of organic life on the earth. It is not possible to define precisely the line which separates the lower portions of these two kingdoms; we may therefore regard them as simply branches of one great group, inseparable below, but widely divergent above. In attempting to separate plants from animals the most we can do is to bring together those characters which separate the greater number of plants from animals, and …

Symbiosis And Mutualism, Roscoe Pound
Symbiosis And Mutualism, Roscoe Pound
School of Biological Sciences: Faculty Publications
Symbiosis and mutualism, in the vegetable kingdom at least, are phenomena accompanying parasitism. Parasites have various effects upon their hosts, according to the nature of the parasite, its mode of life and method of attack. In some cases the host is quickly killed and the parasite becomes a sort of saprophyte upon the remains. In others the host lives longer or is only partially affected. In still others the host lives on side by side with the parasite indefinitely. A further development is attained in cases where the parasite and host not only live together, but are mutually beneficial, and, …

Catalogue Of The Snakes Of Nebraska With Notes On Their Habits And Distribution, W. Edgar Taylor
Papers in Herpetology
The author has published in the proceedings of the Nebraska State Board of Agriculture a complete catalogue of Nebraska serpents including notes and descriptions of the adults and young. Since the preparation of this catalogue Prof. Cope's review of North American snakes has appeared. This together with the fact that the author has had time to review his own studies and add many other notes is sufficient excuse for offering the present catalogue.
In the classification we have followed Prof. Cope. The notes given are confined to the Ophidia or serpents of Nebraska. The range of the collection, which was …

School of Veterinary and Biomedical Sciences: Faculty Publications
MORPHO-BIOLOGICAL CORRESPONDENCE BETWEEN TWO OR MORE MICRO- ETIOLOGICAL ORGANISMS NOT SUFFICIENT GROUNDS FOR PRONOUNCING THE DISEASES WITH WHICH THEY ARE CONNECTED IDENTICAL. The details of this discussion will be found in my report on the swine-plague. It is necessary, however, to touch upon the essential points here also. As was there shown, Hueppe asserts that the European diseases previously mentioned as being caused by a member of this group of belted, ovoid germs, viz., the “ Huhne Cholera, Kaninchen Septikasmie, und Wild Seuche ’ ’ are all one and the same disease, because their micro-etiological organisms have the same form, …

On The Transparency Of The Ether, Dewitt B. Brace
On The Transparency Of The Ether, Dewitt B. Brace
University Studies (University of Nebraska) (1888–1984)
Whether light coming from the remotest members of the visible universe has not been enfeebled to a greater extent than the variation of distance would require, is still an open question. If there be absorption at all, it must be exceedingly small through spaces comparable with the dimensions of the solar system, in order that the light of these distant bodies may be perceived.
It is proposed in the present paper to investigate the phenomena which would occur if the energy were absorbed by the ether itself through frictional forces or imperfect elasticity. If absorption does take place, there must …
