Rules For Official Tractor Tests, Nebraska Tractor Test Lab, Agicultural Experiment Station Dec 1919

Rules For Official Tractor Tests, Nebraska Tractor Test Lab, Agicultural Experiment Station

Nebraska Tractor Tests

The Nebraska Tractor Law known as House Roll 85, 37th session, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of imporved types of tractors and to contribute to a more successful use of the tractor for farming.

It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public. These tests will give reliable information on the power capacity and fuel consumtion of each tractor …


Rules For Tractor Demonstrations, Nebraska Tractor Test Lab Jan 1919

Rules For Tractor Demonstrations, Nebraska Tractor Test Lab

Nebraska Tractor Tests

The object of these rules, instructions and data is to make all tractor demonstrations of this kind comparable and of the greatest educational value. Anyone who has conducted tractor demonstrations in the past has realized the necessity of some standard rules to follow and those who afterwards have referred to the results, deplore the lack of uniformity in the demonstrations and the data. For those who have not had this experience will find that it is a great help to have satisfactory rules to follow.

The value of these demonstrations depends largely upon the accuracy of the data reported on …

Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach Jun 1918

Studies Concerning The Elimination Of Experimental Error In Comparative Crop Tests, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is apparent that many sources of error have unconsciously entered into comparative crop yield tests. The very important matter of overcoming variation in soil conditions as a source of experimental error has been quite extensively studied and reported by various investigators during the past decade. The means suggested for reducing such error have been (1) repetition of plats and (2) correction of yields according to check plats planted to a uniform variety or treatment at stated intervals. Both methods have proved of value and a combination of both may often be used advantageously. Some danger always exists of error …

Leaching Flue Dust, Edwin Alexander Kayser Jan 1916

Leaching Flue Dust, Edwin Alexander Kayser

Bachelors Theses

"The usual method of treatment has been to charge the "flue dust" into reverberatories and smelt it with the regular charge of calcined ore. There was a consequent cost of handling and a serious loss thru furnace draft and boiling, due to the fine state of division of the material and the presence of sulphates, acid, and moisture.

The object of the paper is to treat this material by some leaching process, which will eliminate the above enumerated losses, and at the same time present the finished product at a lower cost, and with a higher extraction per ton, than …


Flotation Applied To Silicate Sludge, Yaro Klepel, Greene Erskine Jan 1916

Flotation Applied To Silicate Sludge, Yaro Klepel, Greene Erskine

Bachelors Theses

"Within the past few years great success has been made of the flotation of sulfids, and to a certain extent of carbonates.

Since sulfids are easily recovered by flotation it seems practicable that silicates could be made to float by first sulfidizing them, and then subjecting them to ordinary flotation treatment.

This problem involves the treatment of a silicate sludge obtained from the Joplin district, the sludge will easily pass through a 250 mesh screen. At the present time this sludge is being sent to the tailings pond.

The experimental work of this thesis was done along the line of …


The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams Jan 1916

The Cost Of Producing Electricity At The Hamilton, Missouri Light And Power Company, Bernerd William Adams

Bachelors Theses

"For those seeking information on the cost of producing electricity in steam plants, an unlimited amount of data may be found in the technical journals and text books. This information, however, is obtained from a careful analysis of the daily and hourly records kept by the largest central stations, hence, production costs are available only where the yearly out-put is several million kilowatt-hours. the small isolated stations of from one hundred to two hundred kilowatt capacity have not as a rule, become progressive enough to keep a complete record of operating costs...The test hereinafter reported was conducted from August 3rd. …


Bulletin No. 139 - The Movement Of Soluble Salts With The Soil Moisture, F. S. Harris May 1915

Bulletin No. 139 - The Movement Of Soluble Salts With The Soil Moisture, F. S. Harris

UAES Bulletins

In irrigated districts, where excessive quantities of water are used, there is usually an accumulation of alkali salts in the soils of the lower lands. These salts are probably dissolved from the soils through which the percolating waters pass and are carried along until the water comes to the surface and is evaporated, when the salts are deposited as a crust at the surface. Many of the most fertile soils of the arid regions have been ruined by the bringing to the surface of soluble salts in such large quantities that the growth of crops is prohibited. The rapidity with …


Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour Jan 1915

Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

ln southern Harlan and Franklin counties, there occur many acres of green quartzite which must be of commercial consequence when made available. It is a neglected resource upon which important industries are sure to be based. With the development of this bed in view, the Nebraska Geological Survey has examined this area. and through this leaflet wishes to place the results before possible investors.


Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour Jan 1915

Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska1. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.


The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr Jul 1914

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. 134 - The Nitric Nitrogen Content In The Country Rock, Robert Stewart, William Peterson Jun 1914

Bulletin No. 134 - The Nitric Nitrogen Content In The Country Rock, Robert Stewart, William Peterson

UAES Bulletins

In many arid sections of Western America there have been reported marked accumulations of nitrates in the cultivated soil. Hilgard,(1) who was the first to observe these accumulations, believed that the nitrates are being formed at the present time by the rapid nitrification of the organic matter contained in the soil. In Colorado there has been considerable trouble with orchards dying; the death of the trees in some cases has been attributed to the excessive accumulations of nitrates in the cultivated soil. These accumulations are due, according to Dr. Headden,(2) to the fixation of atmospheric nitrogen by bacteria now at …

Notice Of Jelly Fishes In The Carboniferous Of Nebraska, Medusina Walcotti, Erwin H. Barbour Jan 1914

Notice Of Jelly Fishes In The Carboniferous Of Nebraska, Medusina Walcotti, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

In visiting the quarries of the State, certain quadripartite objects suggesting the form of jelly fishes have long attracted the writer's attention. They are large and coarse, and were assumed to be imitative concretions. However, the total number observed seems to strengthen the probability that they are of organic origin. In the fall of 1913, while conducting a field class through the Burlington Quarries, located about two miles northwest of South Bend, they were noted again in a new locality, and three specimens were obtained. Two of these were unusual examples, and showed sufficient structure to identify them with the …


Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always Jun 1913

Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always

Nebraska Agricultural Experiment Station: Historical Research Bulletins

These experiments were carried out in connection with and subordinate to various soil investigations, the object being to determine the relation of the final water content of the soil to the hygroscopic coefficient and to determine to what extent the moisture was removed from the different portions of the subsoil not penetrated by plant roots.


Bulletin No. 122 - The Nature Of The Dry Farm Soils Of Utah, John A. Widtsoe, Robert Stewart Jan 1913

Bulletin No. 122 - The Nature Of The Dry Farm Soils Of Utah, John A. Widtsoe, Robert Stewart

UAES Bulletins

Successful farming in Utah is dependent upon two main factors: First, the economic use of irrigation water upon the lands lying under the irrigation ditch, and second, upon the correct practice of the principles of dry farming upon those lands not susceptible to irrigation. Dry farming in Utah is, therefore, of great importance and it becomes essential to learn something of the nature of the dry farming soils of the State.


Bulletin No. 121 - The Soil Of The Southern Utah Experiment Station, John A. Widtsoe, Robert Stewart Jan 1913

Bulletin No. 121 - The Soil Of The Southern Utah Experiment Station, John A. Widtsoe, Robert Stewart

UAES Bulletins

The soil of the Southern Utah Experiment Farm is a very interesting type: it is highly charged with gypsum and thereby presents a condition unique in reported studies of the soils of America. Gypsiferous soils are characteristic of a large portion of Southern Utah; many of them are derived from shale, others from sandstone, impregnated with gypsum.
