The Effect Of Climate And Soil Upon Agriculture, Russell R. Spafford
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. …
Evaporation And Plant Zones In The Cedar Point Marsh, Paul B. Sears
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, …

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 …
Raising The Dairy Calf, E. G. Woodward
Raising The Dairy Calf, E. G. Woodward
University of Nebraska-Lincoln Extension: Historical Materials
There are in Nebraska more than 600,000 dairy cows. The average period of usefulness of the dairy caw is not more than eight years. This means that to maintain the dairy herds of Nebraska at their present size between 70,000 and 80,000 heifer calves must be raised each year. To mate these cows properly with dairy bred bulls will require the rearing of about 8,000 bulls yearly. Aside from the necessity of maintaining the herds at their present size, the importance of calf raising to the Nebraska dairyman lies in the fact that this is the surest and most satisfactory …

The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr
The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The profitable cultivation of the non-irrigable lands in west central and western Nebraska is limited by the amount and efficient use of the precipitation. There are tracts of land in the sand hills and minor tracts of badly worn heavier soils where the need of soil fertility is becoming evident. But, in the main, the great problem at present is not one of soil fertility, but of how to get enough water to make use of the fertility now present. The rainfall of this section, which varies from an actual shortage to seldom more than a meager sufficiency, makes it …

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

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 …

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.

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 …

Two Lincoln (Nebraska) Typhoid Fever Epidemics Of 1911 And 1912., Herbert H. Waite
School of Biological Sciences: Faculty Publications
On August 29, 1912, I was requested by the Board of Health of the city of Lincoln to make an investigation to determine if possible the origin and cause of an outbreak of a disease reported as typhoid fever which was then prevailing. This outbreak was said to be most prevalent in one particular portion of the city and consequently attention was turned to that portion. Of the cases reported an investigation was made of over 60 individuals and after considering all the probable causes for the majority of those affected the conclusion was reached that all could be logically …
Bulletin No. 117 - The Yields Of Crops With Different Quantities Of Irrigation Water, John A. Widtsoe, L. A. Merrill
Bulletin No. 117 - The Yields Of Crops With Different Quantities Of Irrigation Water, John A. Widtsoe, L. A. Merrill
UAES Bulletins
The value of an irrigated farm rests In the land and in the water available for irrigation. Usually the water right for an acre is worth considerably more than the land itself. Under irrigation it is just as important to secure the largest yield per unit of water as it is to obtain the largest yield per acre. Owing to the high cost of water, the production per unit of water is frequently more important than the yield per acre. In Utah and the other irrigated states, the water available for irrigation, or that which may be made available, is …

Circular No. 7 - Labor Saving Devices For The Farm Home, Leah D. Widtsoe
UAES Circulars
This paper was written for and read before the first International Congress of Farm Women held at Colorado Springs, October 17th to 21st, 1911. A few changes have been made in the manuscript and some illustrations added.
The name indicates that it is written for the progressive farmers of some means--since all labor saving devices cost more or less money. The farm home which finds it difficult to keep flour in the barrel, naturally will not be interested in $125.00 water systems--except as an ideal they may attain to some day, and ideals are always helpful. To find ways and …

Present Methods Of Teaching Entomology, H. T. Fernald
Present Methods Of Teaching Entomology, H. T. Fernald
Department of Entomology: Faculty Publications
In teaching entomology, much depends upon the ultimate aim of the student. A course in introductory entomology, whether as a required or an elective subject is sure to include many students who will not continue the subject farther. It is at least probable, that these students will form over half of the class, and accordingly, the introductory treatment should be arranged on the basis of the greatest good to the greatest number. This will usually mean some slight knowledge of insect anatomy, particularly external anatomy, and a general survey of insects as a group, with special attention to the pests …
