Transpiration As A Factor In Crop Production, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of experiments reported in this bulletin has been to determine principles according to which water is used by crops. In many agricultural districts, water is frequently a seriously limiting factor in crop production. It has been thought that some means might be devised through a correct understanding of the principles involved, whereby economy in the use of water in farm practice could be increased. In this effort there are two chief points of attack, namely, (1) adjusting the external factors to the needs of the plant, and (2) selecting plants adapted to the conditions.

New-World Analogues Of The English And Scottish Popular Ballads, Louise Pound

Mid-West Quarterly (1913–1918)

I wish to question in this paper, for the second time, two currently accepted affirmations concerning the processes and the development of English popular ballads in the Old and the New World. The first of these affirmations is that a body of folk-song exists in America which supports the theory of “communal” origin for the English and Scottish popular ballads,—an idea which has made considerable headway since it was advanced five or six years ago. The second is that real ballads and ballad-making are extinct. This position is frequently taken in this country, and, being sustained by excellent authority, it …

Ecological Investigations Upon The Germination And Early Growth Of Forest Trees, Richard H. Boerker

University Studies (University of Nebraska) (1888–1984)

Briefly stated the purpose of the present investigation is to inquire into the effect of the more important habitat and seed factors upon the germination and early development of certain American forest trees in control cultures in the greenhouse for the purpose of obtaining data that may be used in the ~ilvicultural management of these species.

Prefatory Note 1 / Preliminary Considerations 7 / Historical 7 / Classification and Resume of Habitat Factors 11 / The Germination Process 15 / Method of Attacking Problem at Hand 19/ Methods and Apparatus Used 2 1/ The Control of Habitat Factors 24 / …

A Genetic Study Of Plant Height In Phaseolus Vulgaris, R. A. Emerson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

When pole and bush beans are crossed, 3:1 segregation results whether the pole bean is very tall or only medium in height and whether the bush bean is very short or relatively tall. To determine the interrelation of these two types of behavior by an analysis of the factors concerned in height of plants in beans and by a study of their mode of inheritance was the object of the investigations reported here.

Gongylonema In The Role Of A Human Parasite, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

A specimen of Gongylonema, probably G. pulchrum, has been recovered from man. This species is normally a parasite of the pig.

Infection of the human host was brought about probably by the ingestion of larvae in the infective stage which had developed in some insect. Very likely the croton bug, known by experiment to be able to serve as intermediate host for this species, was the source of the infection which might readily occur by accident.

The presence of the parasite was accompanied by clinical symptoms indicating marked digestive and nervous disturbances, associated with anemia. These symptoms …

On A New Subspecies Of Porcupine From Nebraska, Myron H. Swenk

University Studies (University of Nebraska) (1888–1984)

Publication NO.2 of the Nebraska State Biological Survey.

Nebraska porcupines all belong to the yellow-haired species (Erethizon epixanthum) , and these animals have never been abundant in the state. Formerly, however, they were much more numerous than today, and enjoyed a more extended range in the state than they do at the present time. Up to about 1885 these animals occurred across the northern portion of Nebraska east at least to Pierce and Madison counties, there being records of four specimens secured along the small streams tributary to the Elkhorn river in these two counties between 1870 and 1885. Also, …

Evaporation And Plant Zones In The Cedar Point Marsh, Paul B. Sears

Papers in Ecology

Yapp in trying to account for the xerophytic structure of marsh plants by means of evaporation studies has shown a definite correlation to exist between the strata of marsh vegetation and rates of evaporation at corresponding levels. The following studies were made in an attempt to discover what additional correlations, if any, exist between distribution of marsh plants and the evaporational power of the air at different portions of the habitat. While the exact quantitative significance of such work as the following may be brought into question, as it often is, the striking results obtained by Transeau, Livingston, Fuller, Weaver, …

Notes On The Trematode Genus Telorchis With Descriptions Of A New Species, Horace Wesley Stunkard

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

The study of abundant material, both adult and immature forms from the trematode genus Telorchis, including four species new to science and others from new hosts and localities, has given data for the first general discussion of the genus yet made. The sub-genera Telorchis and Cercorchis proposed by Lühe intergrade and can not be retained. T. augustus and T. leptus if correctly described should be removed to an independent genus. The new and some older species are discussed in detail.

A Brief Sketch Of The Life And Work Of Charles Edwin Bessey, Raymond J. Pool

Papers in Systematics and Biological Diversity

Charles Edwin Bessey, professor of botany and head of the department of botany in the University of Nebraska since 1884 and a conspicuous figure in American science and education, passed away at his home in Lincoln on February 25, 1915, after a critical illness of four weeks.

The Bessey family is of French extraction, the original form of the name being Besse. The tradition is that the early members of the family, who were Huguenots, were compelled on account of religious persecution to flee to England from the old home near Strassburg in Alsace. This exodus occurred in the latter …

American Species Of The Genus Atractides, Ruth Marshall

School of Biological Sciences: Faculty Publications

The water mites of the genus Atractides belong to a small subfamily, the Hygrobatinae. About ten species have been described by European hydrachnologists for Europe; two of these species have been reported by them also from North America, while one species is described for Madagascar. Three new species are now added to the list for the United States. All of the material, thirty-eight individuals, was found by the author in small lakes in Wisconsin, United States

Mallophaga From Apteryx, And Their Significance, With A Note On The Genus Rallicola, Launcelot Harrison

Harold W. Manter Laboratory of Parasitology: Library Materials

Regards the skins of five species of Apteryx in the collection at the Cambridge University Museum in England. From these were collected three species of Mallophaga belonging to the genus Rallicola. These are described with discussion about the significance of this occurrence upon Apteryx, from which no Mallophaga have previously been recorded.

A Handbook Of Nebraska Grasses : With Illustrated Keys For Their Identification, Together With A General Account Of Their Structure And Economic Importance, E. Mead Wilcox, George K. K. Link, Venus W. Pool

University of Nebraska-Lincoln Extension: Historical Materials

The true grasses belong to the one family Poaceae, often called Gramineae, and constitute a very well defined natural group of plants. This family comprises upward of 3,000 species distributed among almost 300 genera. From the economic point of view the family is of supreme importance thru the fact that here belong the cereals, which supply a large part of the food of man, and the forage grasses which are so important as feed for our domesticated animals.

The genera and species are for the most part separated by artificial characters—a fact which renders their study and identification extremely difficult …

Otacariasis In The Bighorn, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

The ear of a mountain sheep at Estes Park, Colorado, USA, was found to be heavily infested with a Sarcoptid mite which was not the common scab mite of domesticated sheep but is new in this country.

This form is similar to a mite found in the ear of goats in the Pyrenees and in the Congo. Nevertheless there is reason to consider it a new species and it is named Psoroptes cervinae.

The complaint to which it gives rise is likely to be serious if its effects are like those of the related European form. The Bighorn …

The Habits, Life History, And Structure Of A Blood-Sucking Muscid Larva (Protocalliphora Azurea), Albert Francis Coutant

Harold W. Manter Laboratory of Parasitology: Library Materials

While studying the blood parasites Halteridium and Proteosoma, and the Filaria of the common crow (Corvus americana), my attention was attracted by an external parasite of some young nestlings which were brought into the laboratory. Observations on this parasite, which proved to be the larva of Protocalliphora azurea (Fall.), form the basis of this paper. The parasite is the immature form of one of the so-called "blue-bottle" or flesh-flies, whose larvae are generally regarded as useful scavengers. More careful observations on the life-histories of many species, however, have shown that they may be, and often are, parasites …

Research Bulletin 6, Transpiration as a Factor in Crop Production, 1915

"Ground Arms", Paul H. Grummann

Mid-West Quarterly (1913–1918)

Every great' novel is born of the conviction, on the part of the author, that he has had experiences or conceptions which the race should share in the interests of a fuller manhood and womanhood. Frequently such novels are evolved in the throes of a great movement-religious, political, or social; and the novel with a purpose is the result. If these premises are correct, it would seem at first sight that the novel with a purpose is the highest type of novel, for if the novelist is the mediator of ideals, that writer who throws himself headlong into a great …

In Defence Of The Professor Who Publishes, Alvin S. Johnson

Mid-West Quarterly (1913–1918)

At the present time, when our whole educational system is under criticism, it would be remarkable if any tendency in university life were to escape the searching scrutiny of laity and schoolmen. University ideals and university organization have been exploited in books and articles without number. Everybody has taken part in the work of defining the respective powers of president and board, of determining the scope of student self-government, and the appropriate relations of the university to the community at large. With these large problems discussed to the point of universal exhaustion, we may well turn our attention to others, …

Pacifism As An Offspring Of The French Revolution, Charles Kuhlman

Mid-West Quarterly (1913–1918)

Modem pacifism is a by-product of social democracy. It originated in the extreme left wing of the French Revolution. Its first representatives are found among those men of terror and blood who made themselves known and abhorred throughout the world as "Jacobins. " The revolution was, at its inception, a revolt against the absolute monarchy in France only. It was not until this monarchy had been completely overthrown that it took the form of a declaration against practically all the other governments of Europe. The classic argument of kings, the bayonet, failed Louis XVI when the army stood aloof or …

Some Legal Aspects Of The Invasion Of Belgium, Sumner Allen

Mid-West Quarterly (1913–1918)

In the fifth century before the Christian era the two powerful states of Greece, Athens and Sparta, were at war. Greek culture was then at its highest level, and Athens was the centre-in the phrase of Pericles, "the school of Hellas." Its attainments in art, letters, and government were a source of pride and the basis of the Athenian claim of superiority. During the progress of that long and terrible war, the Athenians conceived that the neutrality of a small colony on the little island of Melos was a military disadvantage, and an army was sent to reduce it to …

Joseph Chamberlain, The Radical, Cephas D. Allin

Mid-West Quarterly (1913–1918)

The approaching retirement of Joseph Chamberlain from the House of Commons awakens a sympathetic interest throughout the world. It is pathetic indeed to see the oft-victorious warrior stricken down and borne from the field at the very moment of the triumph of his political foes. Time has turned against the venerable statesman. The principles for which he so stoutly fought are apparently going down to defeat. The Home Rule question, which he had hoped was buried, has risen again to haunt his declining days. The policy of preferential trade, to which he owes his imperial reputation, has been practically set …

Colonial Aspects Of The War, Cephas D. Allin

Mid-West Quarterly (1913–1918)

In a recent speech Mr. Asquith declared that the greatest mistake that Germany had made in respect to the war was in her failure to recognize that there was a British Empire. Great Britain has long been regarded as a small, insignificant island off the European coast. She has been looked upon as a second-rate European power somewhat in the class with Italy and Spain. And such she is in fact if considered by herself alone. But the war has revealed, what the Empire has long since known, that England is an imperial rather than a European nation, that she …

The Renaissance, E. Benjamin Andrews

Mid-West Quarterly (1913–1918)

In the early part of the fifteenth century a change as subtle and indefinable as it was significant, came over the spirit of European society. Without sharp break with the past, involving no strictly new creation, no sudden or unheralded revolution of ideas, gradually rose an altered mode of viewing man, the world, life-far less theological than the old, less respectful to tradition, more confident in man's powers and future-in fine, laic and human. Renewed study of classical antiquity was sign and instrument, rather than essence, of the new movement. If men looked back, it was mostly to clear their …

Nietzsche, P. H. Frye

Mid-West Quarterly (1913–1918)

On account of the attention which Nietzsche has been attracting of late, the occasion seems a favourable one for reviewing once more his life and work. In a letter to one of his acquaintances, written in March, 1884, he himself prophesies with the proverbial modesty of genius that" in fifty years, perhaps, will the eyes of some few (or of one, for it requires genius) be opened to what has been done through me. For the present, however, it is not only difficult but quite impossible (in accordance with the laws of 'perspective') to speak of me publicly without falling …

Giosuè Carducci, Ruth Shepard Phelps

Mid-West Quarterly (1913–1918)

It is a commonplace to say that the nations of the north have seen in Italy from the first the home of romance, the pleasure-place of the imagination. And they have always delighted to heighten her effects. From Chaucer to Walter Pater she has been ever the land of mystery and tragedy, of soft lascivious manners and gorgeous crimes, of a deep magical melancholy which has laid a spell upon the northern mind-a spell, however, which that mind itself and its tastes have largely created. The deep racial differences have fascinated the Teutonic imagination, which in turn has exaggerated them; …

Canada And The War, J. E. Le Rossignol

Mid-West Quarterly (1913–1918)

Canada is a protected country and the Canadian people have given little thought to the danger of war. On the Atlantic and Pacific coasts she is protected by the sea; on the north there is a wilderness of barren land, a barrier of ice and the Arctic Ocean; on the south there is a good neighbour, with whom she has had no serious trouble for a hundred years. There are no enemies close at hand, and the danger from distant foes has always seemed remote and problematical.

The Diplomatic Background Of The European War, Bernadotte E. Schmitt

Mid-West Quarterly (1913–1918)

When on August 1, 1914, the fateful news came over the wires that Europe stood at Armageddon, the people of this country were scarcely able to accept the fact, for it was difficult to understand why the flower of European manhood should be sent forth in arms to shatter the cultural and material progress of a century. But to the close student of European diplomacy it has long been evident that some day the conflicting interests of the Great Powers and some of the smaller states, an intricate system of alliances, ententes, and secret agreements, and the armaments accumulated …

German Versus English Aggression, A. D. Schrag

Mid-West Quarterly (1913–1918)

The present state of public opinion is quite inexplicable unless we remember that great wars are periods of the abnormal, not only in the political, the industrial, and the commercial, but in the intellectual sphere as well. The mental chaos that confronts us on every hand can be accounted for only on the theory that wars are days of sickness in the life of the human race. The bold assertions, wild speculations, fanciful prophecies which one hears on every hand must be regarded as the incoherent prattle of a delirious public mind. Not only the unthinking public but men of …

French Opinion Of Our Civil War, Louis Martin Sears

Mid-West Quarterly (1913–1918)

In these days when America is the spectator of world war, it is of increased interest to notice the views of Europe when America was the battle ground itself. An awakening interest in this study has recently impressed upon our public the paramount importance of the English attitude toward the war; and our vast debt to Cobden, Bright, and John Stuart Mill and other English Liberals has stirred the national gratitude. The Liberals of France played an equal role. Their voice, not loud but deep, operated to curb the opportunism and militancy of Napoleon III and his cabinet of adventurers. …
