Below is given a table of the American genera, exclusive of Crelioxys, assigned by Ashmead to his subfamily Crelioxyinre. As Prof. Cockerell has long ago pointed out, these are not all closely related and must be split up into several groups, so my table is one of convenience only.

Bulletin No. 142 - Irrigation Of Peaches, L. D. Batchelor

UAES Bulletins

The writer took up the study of the irrigation of peaches in the spring of 1913 after being connected in a co-operative way with a similar problem during the years 1911 and 1912. The results which follow are primarily from notes taken during 1913 and 1914. Free access has been made, however, to notes taken on the similar problem noted above, when the author was associated with Prof. Walter McLaughlin in connection with a co-operative irrigation problem. Some of the results of 1913 were materially influenced by the treatment of the orchard in 1912.

Circular No. 21 - Dry-Farming In Utah, F. S. Harris, A. D. Ellison

UAES Circulars

It was only a few years after the settlement of Utah in 1847 that occasional attempts were made to raise crops without the use of irrigation water, but these first attempts usually resulted in failure. Not until in the sixties could any degree of success be claimed. About this time, farmers in the valley of the Great Salt Lake and in Cache Valley began raising crops regularly on land located above the canal. From then to the present time a measure of success has been enjoyed by the better dry-farmer in some sections, and hardly a year of complete failure …

The Effect Of Climate And Soil Upon Agriculture, Russell R. Spafford

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

Field studies in farm management are at present almost whclly confined to measu ring the profitableness of a farm business and analyzing the effect of those factors which fall largely within the control of the farm operator. While factors beyond individual control have always been recognized in field work, very little attempt has thus far 'been made to measure their influence upon farming; It is true that with present weather, soil, botanical, census, and farm management data only preliminary measurements can be made, but nevertheless such measurements do much toward correlating what at present are disconnected facts in agricultural science. …

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, …

Parnassius Apollo In Bayern Und Einigen Grenzbezirken, Max Bachmann

An

Als H. Stichel im Jahre 1899 den mitteleuropäischen Parn. apollo von der nordischen Rasse unter dem Namen geminus abtrennte, hat diese Teilung nicht die uneingeschränkte Anerkennung der Entomologen gefunden und als er dann später im Jahre 1906 noch die Unterart melliculus aufstellte, bedeutete diese Neuerung „ einen Stich ins Wespennest", wie er sich selbst ausdrückte. Der Grund hier-für ist jedoch kaum in einem Mangel der Zweckmäßigkeit begründet, sondern der ungenauen vom Autor selbst nur als relativ brauchbar bezeichneten Diagnose zuzuschreiben. Für SticheI bedeutete geminus einen Kollektivbegriff für „ die Gesamtheit der den europä-ischen Hoch- und Mittelgebirgen" angehörigen Formen mit Ausnahme …

Bulletin No. 141 - Variation In Minimum Temperatures Due To The Topography Of A Mountain Valley In Its Relation To Fruit Growing, L. D. Batchelor, F. L. West

UAES Bulletins

The most destructive weather enemy in all fruit growing sections is the late spring frost which frequently occurs after warm weather has caused the fruit blossoms to become fully developed. The variation in severity of such frosts in mountain valleys is a phenomenon well known to the practical orchardist. The actual extent of this variation and the contributing causes have claimed only a very little attention from scientific workers in the mountainous regions. The present publcation is a preliminary report of investigations which were planned to measure the extent of such temperature variations, and acertain if possible some of the …

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.

Staminate Flowers In Anemone, Clarence Elmore

School of Biological Sciences: Faculty Publications

Anemone caroliniana is one of the most common of spring flowers in the vicinity of Grand Island, Nebraska. For several years I have noticed that in a large number of the flowers the pistils are lacking. In 1914 in one collection of 250 specimens, 190 were perfect, 50 had stamens only, and 10 had few or abortive pistils. There were none that had pistils only. The condition found is indicated in table I.

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 …

Bulletin No. 140 - The Summer Pruning Of A Young Bearing Apple Orchard, L. D. Batchelor, W. E. Goodspeed

UAES Bulletins

The majority of horticultural writers seem to favor the summer pruning of apple trees. The practice, and the arguments made in its favor vary widely and in some instances seem almost contradictory. On the other hand some experimenters and practical workers have obtained negative results by summer pruning from the view-point of crop production and tree growth. Dickens(1) caused unproductive ten year old apple trees in Kansas to bear satisfactorily during the fourth year of summer pruning. The Gardners' Chronicle(2) compiled the opinions of more than one hundrend eighty-five fruit growers who practiced summer pruning, and about 82% of these …

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
