Tests Of The Strength Of Concrete
Tests Of The Strength Of Concrete
Conservation and Survey Division
Since the use of concrete is becoming so general it seems quite appropriate that the tests of concrete in which any Nebraska material forms a constituent part should be recorded where they may be obtained by those interested.. The following tests were made in the Testing Laboratory of the University of Nebraska, and though very limited in number may be expressive of the qualities of concrete mixed from these materials.

The Nebraska Geological Survey as now constituted has been in operation since 1891, but it has enjoyed state aid during the past four years only. Considering the size of the commonwealth and the limited appropriations for geological work, unusual progress has been made.

Conservation and Survey Division
The Nebraska Geological Survey as now constituted has been in operation since 1891, but it has enjoyed state aid during the past four years only. Considering the size of the commonwealth and the limited appropriations for geological work, unusual progress has been made. Since no report covering the work of the first biennium was prepared it will be included incidentally in this paper. Briefly stated the Nebraska Geological Survey during the past biennium has devoted especial attention to the industrial resources of the state, prepared ten o! twelve reports in manuscript form, published eight reports completing volumes I and II, …
Opening Of The Indian Territory, G. E. Condra
Opening Of The Indian Territory, G. E. Condra
Conservation and Survey Division
The opening of Indian country has continued from Colonial days to the present. Usually it has resulted from force and treaty, the strong dispossessing the weak. As a result, the Red man has, in general, moved frontierward, ahead of industrial waves, remaining for a longer time only on reservations set aside for tribes. The Indian's struggle even on these reserves has been a losing one, resulting largely from war, disease, and the cupidity of whites. History shows that Indian life and Indian institutions have not prevailed against the white man's civilization and commerce. GATHERING THE TRIBES. The Indian Territory and …

Evidence Of Loess Man In Nebraska, Erwin Hinckley Barbour
Evidence Of Loess Man In Nebraska, Erwin Hinckley Barbour
Conservation and Survey Division
Unconsciously or otherwise an investigator is often influenced to see that which seems confirmatory rather than that which is contradictory to his conceptions and beliefs. But in conducting the search for evidence of human remains in the Pleistocene the writer has striven against this psychological tendency and has aimed to be severely critical and exact.

Some Kentucky Clays, Including Kaolinic, Plastic And Fire Clays: Clays In Several Parts Of Kentucky, With Some Account Of Sands, Marls And Limestones, Aug Foerste, James H. Gardner
Bulletin--KGS
The bulletin is preliminary in character and is offered now simply in order to meet the urgent calls for all information concerning our clays that is at present available. A more comprehensive report, in which not only the geology and distribution of our clays, but also their technological values, will be given, will follow in due course.
Data for such a bulletin are being gathered as rapidly as circumstances will permit. Among the clays upon which more field work is required are some of those associated with the coals and Conglomerate Measures of the Eastern Coalfield; those in other Lower …

The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass
The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass
Graduate Student Theses, Dissertations, & Professional Papers
Since coming to Montana in the spring of 1894 I have spent rnuoh of ay time in studying the lake bed deposits in the western part of the state, and in collecting and studying the vertebrate fossils found in them. These deposits occur in nearly every large valley in the westem part of the state. I have myself observed them in the valleys of the upper Missouri (above the re-rrion of Helena), Gallatin, Madison, Jefferson, Beaverhead, Ruby, Big Hole, Hell Gate, and Bitter Boot rivers, and their tributaries.

THE PROBLEM OF OUR SOILS AND SOIL MOISTURE.
The soil survey of the state, which was begun by the author in November of 1892, has progressed to the point where it might be considered finished. That is, one or more samples of soils have been taken from every distinct soil region in the state-in fact, most of the separate counties are represented, and mechanical analyses of many of these have already been made. However, in consideration of the size of our counties, the work will not be declared complete until each is represented in the state museum by soil prisms …
Bulletin No. 38 - Preliminary Report On Seepage Water And The Underflow Of Rivers, Samuel Fortier
Bulletin No. 38 - Preliminary Report On Seepage Water And The Underflow Of Rivers, Samuel Fortier
UAES Bulletins
Into a box holding one cubic foot, or seven and one-half gallons of dry sand, one can usually pour from two to three gallons of water without causing any overflow. If the particles of sand were of the same size and cubical in form, they could be packed into a solid mass; and a cubic foot, instead of weighing about 100 pounds--the average weight of dry quartz sand--would then weigh about 165 pounds. But sand grains are irregular in form, and come in contact with adjacent grains only at particular points, thus enclosing spaces or voids, which in dry sand …
