Circular No. 15 - Pastures And Pasture Grasses For Utah, F. S. Harris Nov 1913

Circular No. 15 - Pastures And Pasture Grasses For Utah, F. S. Harris

UAES Circulars

Since the earliest records of man his domestic animals have secured a large proportion of their forage from pastures. Before crops were planted and harvested by man the wild grasses furnished the chief food for numerous kinds of animals, and the cutting and curing of hay came as a later development to supplement natural pasturage in seasons of scarcity.


Circular No. 14 - Housing Farm Poultry, Byron Alder Nov 1913

Circular No. 14 - Housing Farm Poultry, Byron Alder

UAES Circulars

With the exception, perhaps, of actual starvation of the fowls themselves, there is no other factor in connection with the keeping of poultry that will affect egg production and good vigorous growth so decidedly as poor or improper methods of housing. This circular sets forth some of the essentials of a good house for Utah conditions, and offers plans of three houses in which an attempt has been made to include these essentials. The ideas and plans presented here do not represent anyone person's original work. They are a compilation of the work done on this subject by those who …

While collecting Ichneumonoidea in New Brunswick, Mr. A. Gordon Leavitt also collected a number of other Hyrnenoptera, and below is given a report on most of the Apoidea. Some of the material, mostly Megachilinae, Sphecodes and male Halictus, has not been identified, and is not included. A few of the determinations were made by Mr. H . L. Viereck, and credit is given in the proper places.


Bulletin No. 123 - Farm Drainage: A Manual Of Instruction, Chas F. Brown Aug 1913

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. 126 - A Comparison Of First, Second And Third Crop Alfalfa Hay For Milk Production, W. E. Carroll Aug 1913

Bulletin No. 126 - A Comparison Of First, Second And Third Crop Alfalfa Hay For Milk Production, W. E. Carroll

UAES Bulletins

In most sections of the State three crops of alfalfa hay are harvested. There is a widespread opinion among practical feeders in this locality that these crops of hay are not of equal value for feeding purposes. Especially is this true when feeding dairy cows is considered. The belief is so strong in some cases that farmers have said they would exchange three tons of second crop hay for two of first crop when feeding milk cows. Third crop hay is given second choice.

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 Aug 1913

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 …


Bulletin No. 127 - Report Of The Richmond-Lewiston Cow Testing Association, W. E. Carroll Aug 1913

Bulletin No. 127 - Report Of The Richmond-Lewiston Cow Testing Association, W. E. Carroll

UAES Bulletins

The function of all domestic animals is to utilize the coarse rough reeds and transform them into something useful to mankind, either food, clothing, or energy. The animal thus acts as a concentrator for low grade ores, so to speak. The class of animals which will produce most human food, clothing, or energy for man from a given amount of feel--other cost being equal--is the most economical and the one which will remain longest with us as population becomes more dense and the question of food supply becomes keener.

Experiments have shown the dairy cow to be probably the most …

A Working Plan For The Woodlands Of The New Haven Water Company; Prepared After Five Years Of Forest Practice, 1908 To 1912, Ralph C. Hawley Jul 1913

A Working Plan For The Woodlands Of The New Haven Water Company; Prepared After Five Years Of Forest Practice, 1908 To 1912, Ralph C. Hawley

Yale School of the Environment Bulletin Series

Soon after the establishment of the Yale Forest School in 1900, the necessity developed for finding forest lands near the city of NewHaven upon which to conduct field work. It was found that many of the most accessible and best timbered tracts were owned by the New Haven Water Company....about 250 acres near the Maltby Lakes were placed under the management of the Yale Forest School. ...a written plan is desirable. The plan is divided into two parts: the first, descriptive of present conditions and passt accomplishments; the second, treating of the policy to be pursued.

Descriptions Of New Hymenoptera, No. 7, J. C. Crawford

Co

Most of the species described in this paper are of economic importance, and for reference in economic literature their early description is desirable. The series from the species of Agromyza is noteworthy in view of the number of species previously described as parasites of the species of that genus. In this paper, in all cases where both sexes of a species are described, that last described is the allotype.


Notes On Some Species Of The Genus Prosopis, J. C. Crawford May 1913

Notes On Some Species Of The Genus Prosopis, J. C. Crawford

Co

This is a valid species, and not a form of P. cressoni as it is given by Metz. Externally the two are easily seperable. P. cressoni has the propodeum coarsely sculptured, while Mesilla has it, very finely wrinkled. The eighth ventral plates of the males are quite different, and are therefore figured. In cressoni the apical lobes are much shorter than the pedicel attaching them to the plate; in Mesilla they are longer than the pedicel.

Alfalfa Inoculation Tests, C. W. Pugsley Apr 1913

Alfalfa Inoculation Tests, C. W. Pugsley

University of Nebraska Historical Extension: Bulletin

During the winter of 1909-10 an effort was made to secure cooperators among the farmers of Nebraska to test the value of inoculating newly seeded alfalfa fields. This investigation was 8uggested by reports received from correspondents during 1909. The names of farmers willing to cooperate were secured by correspondence and by conferences at the various Short Courses held during that year.

In the spring of 1910 about thirty-five farmers, located largely near Broken Bow, Cambridge, Franklin, and Blair, agreed to test the effect of cultures sent by the United States Department of Agriculture, soil from well-established alfalfa fields, and farm …

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. 10 - The Control Of The Alfalfa Weevil, E. G. Titus Mar 1913

Circular No. 10 - The Control Of The Alfalfa Weevil, E. G. Titus

UAES Circulars

During the work with the alfalfa \weevil throughout several very different seasons and in different regions, of the State, a number of methods of control have been developed that bid fair to be of service in combating this insect. The prospect for the alfalfa grower in the infested area looks more hopeful each year. It is the purpose of this circular to give a brief account of the alfalfa weevil, its present distribution, and the principal methods that appear to be of value in its control.
