Bulletin No. 131 - Variety Tests Of Field Crops In Utah, Frank S. Harris, J. C. Hogenson Mar 1914

Bulletin No. 131 - Variety Tests Of Field Crops In Utah, Frank S. Harris, J. C. Hogenson

UAES Bulletins

The number of varieties of practically all the field crops is now very great, and is increasing every year. Each variety has certain growers who believe in it and who do what they can to make it more widely grown. As a result many varieties of crops are found in most every farming community.

This condition is often bad, since it is impossible to build up a good market with a great mixture of varieties of any crop. A much better price can be obtained if each community offers for sale large quantities of a few standard types, rather than …


Bulletin No. 132 - Minor Dry Land Crops At The Nephi Experiment Farm, P. V. Cardon Mar 1914

Bulletin No. 132 - Minor Dry Land Crops At The Nephi Experiment Farm, P. V. Cardon

UAES Bulletins

The investigations conducted at the Nephi substation deal primarily with cereals; other crops, such as alfalfa, peas, corn, potatoes, etc., have occupied only a secondary position in the work of this station. This necessarily has been true because the experiments are confined to dry-land practices, and the cereals unquestionably comprise the basal crops for dry-land farming as it is now understood and practiced in Utah. No crops have been found as yet which yield so profitably on the dry lands as do the cereals, especially winter varieties.

The purpose of this bulletin is to review the work done on the …

Halictus Minutissimus K. Und Seine Verwandten. (Hym.), J. D. Alfken Jan 1914

Halictus Minutissimus K. Und Seine Verwandten. (Hym.), J. D. Alfken

A

Die kleinen schwarzen Halictus-Arten bereiten dem Systematiker viele Schwierigkeit und lassen sich nur bei ausreichendem Material und durch genaue Untersuchung sicher erkennen. Eine reichaltige Sammlung von Apiden, die ich von meinem Freunde A. Moschler in Rossitten zur Bestimmung bekam, entheilt eine grofsere Anzahl der kleinsten Halictus-Arten. Diese bieten mir die gunstige Gelegenheit, den H. minutissimus und die ihm am nachsten stehenden Arten klarzustellen.

A

Von den Herren Dr. H. Brauns in Willowmore, Kapland, und Dr. J. Bequaert in Brugge, Belgien, erhielt ich eine grofsere Anzahl afrikanischer Prosopis-Arten, welche von don genannten beiden Forschern in Kapland, beziehungsweise in Belgisch-Kongo, sowie von Henn G. ArnoId in Rhodesia gesammelt wurden. Einige dieser Arten wurden von H. Friese im Archiv fur Naturgesch. 1911, p. 120-134, andere in dieser Zeitschrift, 1913, p. 573-574 sehr kurz, und in den Zool. Jahrb. v. 35, p. 582-584, 1913 ausfuhrlicher beschrieben. Freund Friese war so freundlich, mir die Typen der von ihm aufgestellten Arten zu leiben, so dafs ich das mir vorliegende Material …

Die Ubrigen Hinterleibsringe tragen seitlich am niedergedrlickten Endrande nur einige wenige Wimperharchen, bei A. humilis dagegen deutlich bindenartig auftretcnde Wimperhaare. Die erhabenen Punktc des tlinterleibs sind, besonders am 1. Hinterleibsringe, viel schwacher …


Bulletin No. 130 - The Change In Weight Of Grain In Arid Regions During Storage, Frank S. Harris, George Thomas Jan 1914

Bulletin No. 130 - The Change In Weight Of Grain In Arid Regions During Storage, Frank S. Harris, George Thomas

UAES Bulletins

In handling grain the question of the changes that may occur in weight after threshing is always before the dealer. If there is any considerable loss during storage his profits are consumed, while if there is a gain it is possible for him to work on a much closer margin.


Revisions Of Some Plant Phyla, Charles E. Bessey Jan 1914

Revisions Of Some Plant Phyla, Charles E. Bessey

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

In the time that has elapsed since the publication of my "Synopsis of Plant Phyla" (University Studies, Vol. VII, NO. 4) it has been possible to make many changes in the arrangement of the orders and families of several of the phyla. On account of their considerable number it is desirable to present these changes in one paper so as to accomplish the revision of the original paper with as little confusion as possible.

The Plant World is here regarded as readily separable into fourteen Phyla (often called "Branches" or "Divisions"). These are subdivided into Classes, and these again into …


Les Bourdons De La Belgique, F. J. Ball Jan 1914

Les Bourdons De La Belgique, F. J. Ball

An

Le genre Boinbus, si intéressant à divers points de vue, est un genre dont la systématique présente encore de grandes lacunes et réclame de nombreuses recherches. La rléfinilion de ses espèces manque absolument de précision. Cela provient de la variabilité extrê me qui y règne. D'une part on peut renconfrer de grandes variations de coloris chez des exemplaires appartenant à une mê me espèce; et de l'autre des individus d'aspect presque identique se difîérencient par des caractères morphologiques importants, mais peu visibles. Il s'ensuit que la liste des espèces et des variétés pour un même pays varie considérablement suivant les …


Synopsis Of The Conjugate Algae-Zygophyceae, Charles E. Bessey Jan 1914

Synopsis Of The Conjugate Algae-Zygophyceae, Charles E. Bessey

School of Biological Sciences: Faculty Publications

A dozen or more years ago the writer prepared a series of papers on these plants, which were published in volumes 21, 22 and 23 of these Transactions, and now it seems that time enough has elapsed to warrant another paper dealing with the same group, and including such revisions as are now made necessary because of our better knowledge of their structure, and the structure of the nearly related plants.

Studies Of North American Bees, Myron Harmon Swenk Jan 1914

Studies Of North American Bees, Myron Harmon Swenk

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

The present paper is the second of the series proposed in a previous contribution on the family Nomadidae (antea, XII, pp. 1- 113 ) , and aims to tabulate and list the bees of the family Stelididae occurring in Nebraska, together with annotations concerning their distribution, comparative abundance and season of flight. As in the previous study, records and descriptions of specimens from outside Nebraska before the writer are included where these seem to add anything to our knowledge of the species concerned.


A Notable Botanical Career, Charles E. Bessey Jan 1914

A Notable Botanical Career, Charles E. Bessey

School of Biological Sciences: Faculty Publications

I have before me the " Report of the Botanist" to the Regents of the University of the State of New York, bearing date of January 1, 1868, covering less than two pages, and signed by Charles H. Peck. There is internal evidence that his services began July 1, 1867, the writer reporting what he had accomplished in the half year since that date. A year later the " Report of the Botanist " covered about 80 pages and included a short general statement followed by (A) List of Species of Which Specimens Have Been Mounted; (B) Plants Collected; (C) …


Rocky Mountain Flowers, Frederic E. Clements, Edith Schwartz Clements Jan 1914

Rocky Mountain Flowers, Frederic E. Clements, Edith Schwartz Clements

School of Biological Sciences: Faculty Publications

AN ILLUSTRATED GUIDE FOR PLANT-LOVERS AND PLANT-USERS WITH TWENTY-FIVE PLATES IN COLOR AND TWENTY-TWO PLATES IN BLACK AND WHITE

The present book is an endeavor to present the materials of the Rocky Mountain flora in preliminary form from the standpoint of the experimental ecologist. The latter is concerned primarily with the relationships of "species" and their subdivisions as an organic expression or measure of habitat differences, and of the competitive relations of the various formations. Whatever the taxonomic value of the numerous segregates of the last decade or two, the fact that the binomial form conceals the relationship to the …


Donovan Family : Scrap Book Of Recipes & Household Hints, Ballymore Jan 1914

Donovan Family : Scrap Book Of Recipes & Household Hints, Ballymore

Books/Book Chapters

Mary Ogle married Captain John Broughton of Maidstone, Kent in 1720 and their daughter Mary was born in Jersey in 1724. She was an heiress and married Edward Donovan, Barrister at Law, of Ballymore, Co. Wexford and 24, Peter Street, Dublin in 1747. They had 21 children, sixteen lived and five died unbaptized. Perhaps, some of her daughters wrote down some of the recipes, as the family would have employed cooks down through the generations.

Their eldest son Richard inherited Ballymore Estate and married Anne Richards, daughter of Goddard Richards at Grange, Co. Wexford. There is little known about her …

The Inheritance Of A Recurring Somatic Variation In Variegated Ears Of Maize, R. A. Emerson Jan 1914

The Inheritance Of A Recurring Somatic Variation In Variegated Ears Of Maize, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

The inheritance of variegation has special interest and importance in genetics. It is with forms of variegation that the only two certainly known cases of non-Mendelian inheritance have had to do. I refer to Baur's experiments with Pelargonium, in which crosses of green-leaved and white-leaved forms exhibited somatic segregations in F1 that bred true in later generations, and to Correns 's work with Mirabilis, which showed green and white leaf color, to be inherited through the mother only. De Vries's con- ception of "ever-sporting" varieties was apparently founded largely upon the behavior of variegated flowers in pedigree …


Multiple Factors Vs. "Golden Mean" In Size Inheritance, R. A. Emerson Jan 1914

Multiple Factors Vs. "Golden Mean" In Size Inheritance, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Groth's preliminary note on the "golden mean" in the inheritance of sizes in SCIENCE of April 17, 1914, pp. 581-584, deserves the attention of geneticists. Its publication is of such recent date that I need only call attention to one or two points that seem to me of particular moment.

In brief, Groth's hypothesis is that the mode

of inheritance in Fl not only of surfaces and

volumes, but also of linear dimensions is to be

expressed by √ab rather than by a + b /2

where a and b are parent sizes. The hypothesis

is based upon …

Bulletin No. 128 - Blooming Periods And Yields Of Fruit In Relation To Minimum Temperatures, A. B. Ballantyne Nov 1913

Bulletin No. 128 - Blooming Periods And Yields Of Fruit In Relation To Minimum Temperatures, A. B. Ballantyne

UAES Bulletins

As noted In Bulletin 124, the Southern Utah Experiment Farm is located in Washington Field, southeast of St. George. This tract of land is comparatively low and flat and bounded on three sides by hills. On the front or north side it extends to the Rio Virgin river, which enters and leaves the valley through small canyons. This entire area has a very poor water and air drainage. Frosts occur here much more severely and much later than on the surrounding bench land.
