A Preliminary Report On The Mechanical Analyses Of The Soils Of Nebraska., Erwin Hinckley Barbour
A Preliminary Report On The Mechanical Analyses Of The Soils Of Nebraska., Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Under the auspices of the State Board of Agriculture the Geologist of the Board undertook, in 1892, the work of collecting the soils of the state, both for permanent display in the State Museum and for the more technical purposes of analysis.
Bulletin No. 52 - The Chemical Composition Of Utah Soils (Cache And Sanpete Counties), John A. Widtsoe
Bulletin No. 52 - The Chemical Composition Of Utah Soils (Cache And Sanpete Counties), John A. Widtsoe
UAES Bulletins
The soils of the State [Utah], as found by the Mormon pioneers of 1847, were virgin in the fullest sense of the word. As far as man knows, only a few patches in Southern Utah had ever been cultivated. For untold centuries the atmospheric forces, unhindered by man's intervention, had been allowed to weather and make fit for agricultural purposes the rock fragments that, washed down into the valleys from the mountain ranges, constitute the soils of the State. For a long period, also, long before human tradition begins, there had not been enough water in the Utah valleys to …

Bulletin No. 46 - Earthen Dams, Samuel Fortier
UAES Bulletins
According to the last census, 92 1/2 per cent of the Utah farms are irrigated. The advancement of agriculture in this State mainly depends upon the water, the available supply of which, in many of the older settled localities of the State, is already wholly utilized during the irrigation period. The future reclamation of new lands in such localities must, therefore, wait on the development of new sources of supply from storage reservoirs, sub-surface supplies, or from a more economical use of the summer flow of the available streams.
From estimates and measurements made by the hydrographers. of the United …
The Occurrence In Nebraska Of Vireo Flavoviridis, Erwin Hinckley Barbour
The Occurrence In Nebraska Of Vireo Flavoviridis, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
A specimen of the Yellow-green Vireo, Vireo flavoviridis, shot at Long Pine, Brown County, has just been received by the Curator of the Museum of the University of Nebraska. This is the first one reported in this State. It is a rare Vireo for the entire United States having been reported, as far as the author can learn, from Texas, California, and Canada only.
A Two-Headed Tortoise, Erwin Hinckley Barbour
A Two-Headed Tortoise, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
INQUIRIES from various quarters have been made so repeatedly for the sequel to the brief story of a young two-headed tortoise, Chrysemys picta, published in the American Journal of Science for October, 1888, that the author is led to believe that a public account thereof will serve more useful ends than many private ones. In order that the sequel may be more intelligible to all, a brief resume of the first paper will be given.
The young tortoise, hatched but a day or so, was found in the marshes bordering West River, New Haven, Conn. The carapace, which was somewhat …

Report Of The Geologist, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
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 …
Lincoln Salt Lake And The Occurrence Of Strepsilas Interpres, Erwin Hinckley Barbour
Lincoln Salt Lake And The Occurrence Of Strepsilas Interpres, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Local ornithologists are considerably interested in the occurrence of the Turnstone (Strepsilas interpres) in this State. Three were shot at Lincoln Salt Lake on the 25th of May of this year. These were secured by Mr. W. D. Hunter of the Department of Taxidermy, and were placed by him in the State Museum. This is the first authentically reported occurrence of this bird in Nebraska. So far as we can learn it is not reported for any of our neighboring States.
Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour
Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
Dr. Theodor Fuchs, criticises at considerable length the nature of Daemonelix as described by the author, in the University Studies, of the University of Nebraska, Vol. I, No. 4, July, 1892, under the title, 'Notes on a New Order of Gigantic Fossils.' When the criticism first appeared it seemed so fraught with errors that they were counted its own best rebuttal, and no attempt to frame a reply was thought of. However, the author has several times of late been reminded that these errors might pass muster and become fixed in the minds of those, at least, who place too …
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 …
Notice Of The Occurrence Of Nyctale Richardsoni, Richardson's Owl, In Nebraska, Erwin Hinckley Barbour
Notice Of The Occurrence Of Nyctale Richardsoni, Richardson's Owl, In Nebraska, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
THE occurrence in this region of Richardson's owl, Nyctale Richardsoni, seems to be entirely established by the recent capture of one in Lincoln. This is a long distance below its southern limit, and its appearance is something of a surprise.
A New Habitat Of The Black-Throated Rock Swift, Micropus Melanoleucus, Erwin Hinckley Barbour
A New Habitat Of The Black-Throated Rock Swift, Micropus Melanoleucus, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
As curator of the museum, I have just procured for the State University of Nebraska a set of bird-skins prepared during the past summer, among which are five skins that must be of interest to ornithologists. They verify the discovery made by Professor Lawrence Bruner of the University of Nebraska, that the White-throated Rock Swift builds and breeds in the precipitous bluffs around Squaw Canon, Sioux Co., Nebraska, and, what is more likely, throughout the Pine Ridge regions, as Professor Bruner has observed them also at Crow Butte, near Crawford, Nebraska.
Living Fossils, Erwin Hinckley Barbour
Living Fossils, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
The great flat slab on which we stood seemed built there to command a view of stoneworts. In the clear lime water of Fall River, S. D., floated great streamers of Chara, fresh and green, yet fading insensibly, first into a dingy, then into a dead looking, and even into a stony mass, as the eye followed it up stream. It was a streamer of living, growing stoneworts that blended into the slabs of "petrified moss" strewn broadcast in the channel around us, and on one of which we stood. But the eye could trace this so-called living fossil or …
Attempted Extermination Of The Pocket Gopher, Geomys Bursarius, Erwin Hinckley Barbour
Attempted Extermination Of The Pocket Gopher, Geomys Bursarius, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
The ravages of the pocket gopher extended very generally throughout the State of Iowa, but came under my own personal notice in the rich and fertile farm lands of Poweshiek County and surroundings. The annual loss they occasioned became a matter of such serious moment to the farmers of this county that on Jan. 8, 1890, an unusually liberal measure was voted by the board of supervisors, to the effect that "a bounty of ten cents a head be paid on gopher scalps taken in Poweshiek County, subject to the same laws and conditions that pertain to the payment of …

The Winnebago County (Iowa) Meteorites, George F. Kunz, Erwin Hinckley Barbour, Joseph Torrey Jr.
The Winnebago County (Iowa) Meteorites, George F. Kunz, Erwin Hinckley Barbour, Joseph Torrey Jr.
Department of Earth and Atmospheric Sciences: Faculty Publications
A remarkable meteor, or meteoric shower, passed over this State at 5.30 P.M., Friday, May 2. In spite of the brightness of the sun, shining at the time in a nearly cloudless sky, the light of the meteor was very noticeable. Its great size, powerful illumination, discharge of sparks, comet-like tail three to five degrees in length, and the great train of smoke which marked its course for a full ten minutes after its passage, made a strong and lasting impression on the minds of all who saw it. Unfortunately the clamor over an exciting game of ball prevented the …

The Winnebago County (Iowa) Meteorites [ Part 2 ], Joseph Torrey Jr, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
A FRAGMENT of the 104-pound "meteorite" found in the northern part of Kossuth County has been examined by us, and we are perfectly well satisfied that it is not of meteoric origin at all. In outward appearance it is suspicious at first sight. The color is darker than that of the other pieces. There is no distinct crust, and no metal present. The gravity taken on a piece weighing about half a gram was 2.83, which is nearly a unit lower than that of the well-established specimens. Under the microscope the crushed mineral shows by reflected light a mass of …
Remains Of The Primitive Elephant Found In Grinnell, Iowa, Erwin Hinckley Barbour
Remains Of The Primitive Elephant Found In Grinnell, Iowa, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
The one alluded to was found in 1884, while breaking ground for the Eagle Block, on the north-east corner of Main Street and Fourth Avenue. This animal, a large adult male, is represented by a tusk (eight feet long and nine inches in diameter), several grinders, lower jaw, and part of zygomatic arch, preserved in the museum of Iowa College. These bones occurred about five feet below the surface, and were in an exceedingly soft and perishable condition, as similarly situated remains usually are; but, owing to the skill of Professor H. W. Parker, the tusk and teeth especially were …

On A Young Tortoise, Chrysemys Picta, With Two Heads, Erwin Hinckley Barbour
Department of Earth and Atmospheric Sciences: Faculty Publications
THE following is a brief description of a young two-headed tortoise, Chrysemys picta, which is a remarkably interesting specimen from the very perfection of its imperfection. It was found in the marshes bordering West River in New Haven, Conn., by Master Leighton Foster, the first part of June, and from appearances had been hatched but two or three days. The single body, with the usual four legs and a tail, carries two equal, and in every respect, normal and well-developed heads and necks, which are throughout entirely free and distinct. The two heads see, hear, eat, drink, sleep, breathe, and …
