Producer Gas, Edward P. Dwyer

Bachelors Theses

"Producer gas, so named owing to being produced in special forms of apparatus known as Producers. The fuel is decomposed into combustible gases, whereby most of the C is burnt to CO, whilst the H either remains free, or is converted into carburretted Hydrogen. Directly above the grate carbonic anhydride is formed but thus is rapidly converted into carbonic oxide; reaction as follows: CO₂ + C = 2CO.

Amongst these heavy carburetted hydrogen (C₂H₄) is that which principally increases the value of the gas as fuel and the drier the fuel used the more of the gas is produced. A …

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

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

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

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.

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

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 …
