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 …

Variation In Oxyurias: Its Bearing On The Value Of A Nematode Formula, Stanley B. Fracker

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

One of the most difficult problems in zoologic science is the classification of round worms. Authors and lecturers, after a carefully outlined and definitely arranged discussion of trematodes and cestodes, are compelled to consider nematodes in a somewhat desultory and inaccurate fashion. Two reasons for this may be given, the greater being the apparent lack of a basis for determining the phylogeny of the major groups, a condition with which we are not at present concerned. The other obstacle is the difficulty of differentiating between species and uncertainty as to the value of different kinds of taxonomic characters. The …

Experimental Ingestion By Man Of Cysticerci Of Carnivore Tapeworms, Maurice C. Hall

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

Having experimentally eaten the larvae of dog tapeworms on two occasions, I undertook to look up the literature on this subject in connection with the ingestion of Cysticercus pisiformis to check the frequently quoted record of T. pisiformis from man. I find that there are more cases of the sort than I had supposed, so I have collected these cases in connection with a recent similar case of my own.

Taenia pisiformis, under the name of T. serrata, has been recorded as a parasite of man by Vital ( 1874), who records, in effect, two cases. One …

Bulletin No. 135 - A Study In Annual Egg Production: Based On The Records Of A Flock Of Seven-Year-Old Hens And Their Progeny, E. D. Ball, Geo. Turpin, Byron Alder

UAES Bulletins

Experimental work in breeding for egg production was started with this flock of Single Comb White Leghorns in 1907. The flock of 1907 was hatched from eggs from a small flock that had been introduced into the plant two or three years before.

After two years' records of these flocks had been completed and studied it was found that nearly three-fourths of the first flock had made better records the second year than they did the first and that there was a great variation in the two years' records of individual hens. This raised the question of whether the first …

Some Species Of The Bee Genus Coelioxys, J. C. Crawford

Co

This paper discusses only species occurring in America north of Mexico and no table to separate the males has been included since Prof. T. D. A. Cockerell published a table for this sex in the Canadian Entomologist for June, 1912, pp. 167-170. The key to the females includes all the species for the region under consideration in which the female sex has been described. In the table here presented the characters used for separating rufitarsis Sm. from comstockii Cress. and lucrosa Cress. from moesta Cress. are the characters used by Prof. Cockerell in a table to separate the types of …

Bulletin No. 133 - Irrigation And Manuring Studies: The Effect Of Varying Quantities Of Irrigation Water And Manure On The Growth And Yield Of Corn, Frank S. Harris

UAES Bulletins

Indian corn is one of the most important crops raised by American farmers. Anything that affects the corn crop of the American farmers. Anything that affects the corn crop of the United States has an influence on the prosperity of the entire country. From an economic point of view therefore, it is important to know as much about the production of this crop as possible. The corn plant also offers an excellent field for scientific investigation independent of any economic bearing.

I. On The Distribution And Composition Of The Humus Of The Loess Soils Of The Transition Region, Morris Blish

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

The main object of this investigation has been to determine the distribution of the humus, to a depth of six feet, throughout the soils in representative virgin prairies of the so-called “transition region" of Nebraska. This region is the large area which extends westward from the Missouri River for a distance of over three hundred miles and which is covered, for the most part, with loess soil. This is, agriculturally, the most important soil in the state of Nebraska, and covers more than half the area of the state. The term "transition region" is employed to convey the idea of …

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

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The inheritance of variegation has special interest and importance in genetics. In this paper I shall present data from maize and attempt to show how they can be interpreted in strictly Mendelian terms.

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 …

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

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 …

Bulletin No. 129 - Codling Moth Studies In 1911: The Driving Spray Under Excessively Wormy Conditions, E. D. Ball, W. M. Ball

UAES Bulletins

Spraying experiments against the codling moth were carried on upon the Smart orchard until the number of worms per tree was reduced to such an extent that no accurate comparisons could be made between different treatments. As a result of the work on this and other orchards, practically every commercial orchard in the valley was by this time well sprayed and the worms reduced to a point where one driving spray per season would keep them under control.

In the meantime a number of questions arose which required very wormy conditions to adequately investigate. Search was therefore made for orchards …

Bulletin No. 123 - Farm Drainage: A Manual Of Instruction, Chas F. Brown

UAES Bulletins

In addition to emphasizing the general need for drainage in the arid regions with reference to seepage and alkali problems, this bulletin is intended as a practical treatise covering all engineering phases of farm drainage, from the general observations concerning specific needs of drainage, to the realizations of successful reclamation. It is made up of two parts for convenience in handling and distribution, Part I, Manual of General Instruction, and Part II, Practical Discussion of Problems.

Bulletin No. 125 - The Chemical Milling And Bake Value Of Utah Wheats, Robert Stewart, C. T. Hirst

UAES Bulletins

The Chemical Department of the Utah Experiment Station, since 1903, has been conducting investigations regarding the value of different wheats grown in the State. The results obtained during the years 1903 to 1906 were published as Bulletin No. 103 of this station. A special investigation in 1910 regarding the influence of the combined harvester on the value of the wheat was conducted and the results obtained issued as Bulletin No. 113. The results reported in the following pages were obtained during the progress of these investigations during the years 1907, 1908, and 1909. The method of milling the samples of …

Bulletin No. 124 - Fruit Variety Tests On The Southern Utah Experiment Farm, A. B. Ballantyne

UAES Bulletins

Since the material contained in the following report of the variety tests on the Southern Utah Experiment Farm was mainly accumulated under plans outlined before the farm was made part of the Utah Experiment Station, it may be well in this connection to give a brief history of its location, management, and a survey of its situation. It was established by an act of the State Legislature approved March 21, 1899, and the site was chosen the following July by a committee appointed by Governor Heber M. Wells. The area selected consists of forty acres located in the southeastern portion …

The Inheritance Of Quantitative Characters In Maize, R. A. Emerson, E. M. East

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The experiments conducted by one of the writers were begun at the Connecticut Agricultural Experiment Station at New Haven in 1906 and removed to the Bussey Institution of Harvard University at Forest Hills, Massachusetts, in 1909. The materials employed in this study consisted principally of crosses of Tom Thumb pop with Black Mexican sweet and of Watson flint with Leaming dent. The number of rows per ear were noted in several other crosses, the parents of which are listed later in this paper. The experiments of the other writer were begun at the Nebraska Agricultural Experiment Station at Lincoln in …

Circular No. 13 - Fruit For Exhibition, Leon D. Batchelor

UAES Circulars

The basis of a good fruit exhibit is necessarily good cultural conditions to produce good fruit. Then it depends on the exhibitor's ability to select his best fruit. Do not wait until the crop is picked to select show specimens. The successful exhibitor makes his prize selections in the orchard while the fruit i still on the tree. By viewing the fruit as it hangs naturally on the tree, and by carefully surveying the different trees in the orchard a good comparison of a large quantity of fruit can be made. The prize fruit is generally on the outermost branches, …

Descriptions Of New Hymenoptera No. 5, J. C. Crawford

Co

Many of the species herein described were received from the Bureau of Entomology, United States Department of Agriculture, having been reared by its various branches in economic investigations as parasites of injurious insects. In this connection attention is especially called to the interesting and varied series reared from Agromyza. In this paper, as in all previous papers published by me, the sex first described is to be taken as the true type and the second as the allotype.

Bulletin No. 119 - The Effect Of Irrigation On The Growth And Composition Of Plants At Different Periods Of Development, John A. Widtsoe, Robert Stewart

UAES Bulletins

Early in the pursuit of the irrigation investigations conducted by this Station, it became important to know the best amounts of water to apply at various stages of the plant's growth. The effect of the total quantity of water applied to a crop, depends in large measure upon the number of irrigations and their times of application during the season. It was thought that some light would be shed upon this problem by examining crops, under variable irrigation methods, at different times before maturity. Such work, also, it was hoped might yield more definite information concerning the manner in which …

Bulletin No. 118 - Methods For Increasing The Crop Producing Power Of Irrigation Water, John A. Widtsoe, L. A. Merrill

UAES Bulletins

The studies of the Utah Station on the effect of water on the yields of crops have shown, first, that as the water applied increases, the total weight of dry matter also increases; and second, that the increase is not in proportion to the amount of water applied, since the less water applied, the larger the yield of dry matter for each inch of water used. These experiments, as reported in bulletins No. 116 and No. 117 indicate with much certainty the best quantities of water to use for various crops. When, however, each farmer has been allotted this best …
