Additions To The Bibliography Of North American Lichens, Bruce Fink

Proceedings of the Iowa Academy of Science

While reading in the botanical library of the University of Minnesota during the summer of 1896, I noticed a number of titles which had escaped Mr. W. W. Calkins, while preparing his bibliography of North American lichens. These I added to some before noted in my own library and began a careful search which extended through the summers of 1897 and 1898; examining also the general library of the University of Minnesota.

A Review Of The Cercopidae Of North America North Of Mexico, E. D. Ball

Proceedings of the Iowa Academy of Science

The family cercopidae, though of world-wide distribution, has comparatively few representatives within our borders, and those few have been but imperfectly known, the literature on the subject being scattered and fragmentary, the generic references often incorrect, and the specific determinations, owing to the extreme variability in color of some species, and the striking similarity of color between others, rendered very questionable. Scarcely one of the more common forms but what has been referred to under at least four different genera and several have more than that number of specific names.

Report On A Fossil Diatomaceous Deposit In Muscatine County, Iowa, P. C. Myers

Proceedings of the Iowa Academy of Science

Previous to the present year no fossil diatoms had been found in Iowa. On October 20, 1898, Prof. J. A. Udden, of Rock Island, Ill., while engaged in work for the Iowa Geological survey, found and sent to Prof. S. Calvin, of the State University, some diatomaceous earth. This material was taken from below the loess in Muscatine County, Iowa, and was turned over to the author for examination. It was of a dull, yellow color, composed of sand and decayed vegetable matter and a few diatoms.

Presidential Address - The Academy And The People, T. H. Macbride

Proceedings of the Iowa Academy of Science

Again, by the decrees of fortune, I appear before you as your presiding officer to extend to you the felicitations of the season and to congratulate you on this, our annual reunion. It is a fortunate thing that so many men can thus come up each from his own field, here to meet in friendly converse with his friend of like pursuit, of like employment, each to derive encouragement and stimulus for further and happier endeavor. This evening there are many reasons for special congratulation. Our roll of fellows and members is longer than ever before; our program shows a …

Observations On The Geology Of Steamboat Springs, Colorado, F. M. Witter

Proceedings of the Iowa Academy of Science

In the year 1873, a division of geologists under the management of Dr. F. V. Hayden, made a survey of the region from Willow Creek Pass, between North and Middle Parks, across the park range down the Yuma or Bear River to the White River, around to Eagle River and up the Grand, of which Willow Creek, in Middle Park, is a tributary. In this report, very brief mention is made of Steamboat Springs, although the trail on their map does not pass nearer than twenty-five or thirty miles to the Springs.

Diatomaceous Earth In Muscatine County, J. A. Udden

Proceedings of the Iowa Academy of Science

While at work on the geology of Muscatine County last summer, the writer found some diatomaceous earth in the south bank of the creek which runs west near the south line of section fourteen, in Cedar Township. It is associated with a peaty layer, which overlies it, and which appears somewhat disturbed. This peat is overlain by fine laminated sand and silt, which here forms the base of the loess. Below the peat bed and the diatomaceous layer there is a white sand without a trace of ferruginous stains. Boggy conditions are indicated, or perhaps the conditions of a lake …

Proceedings Of The Thirteenth Annual Session Of The Iowa Academy Of Sciences: Staff & Committee Reports, Herbert Osborn

Proceedings of the Iowa Academy of Science

The thirteenth annual session of the Iowa Academy of Sciences was held in the geological rooms at the capitol building in Des Moines, December 27 and 28, 1898. In business sessions the following matters of general interest were passed upon.

The Color Of Deep-Sea Animals, C. C. Nutting

Proceedings of the Iowa Academy of Science

The purpose of this paper is to explain the phenomena of bright colors among marine animals living in the sea beyond the depths to which sunlight can be supposed to penetrate to such an extent as to render bright colors visible. Although there are doubtless actinic effects of sunlight at considerable depths, we are safe, I think, in saying that colors cannot be clearly distinguished at a depth greater than 100 fathoms. Photographic experiments show that the "extreme limit of effect of the sun's rays on sensitive plates is at a depth of 250 metres,” or less than 125 fathoms. …

A Generic Synopsis Of The Nearctic Pentatomidea, H. E. Summers

Proceedings of the Iowa Academy of Science

Practically the only keys for determining the genera of our Pentatomidae are those of Stál. These cover only certain divisions of the family, and even in these divisions many recently established genera are not included. His works are, moreover, usually not accessible except to the special student of the Heteroptera, and even when accessible, the fact that they deal with a fauna much more extended than our own, makes them too cumbersome for the ready use of the general student. For these reasons it is thought that a key limited to our fauna and brought up to date may be …

Preliminary Report On The Diatoms Of Iowa, P. C. Myers

Proceedings of the Iowa Academy of Science

Within the last two years the author has often had occasion to congratulate himself for having acted on a suggestion from Prof. B. Shimek, of the State University of Iowa, to take up the study of a group of organisms which hitherto had, from the botanists of this state, received but scant attention.

The Pine Creek Conglomerate, J. A. Udden

Proceedings of the Iowa Academy of Science

In the right bank of the west branch of Pine Creek, a short distance north from where it leaves section thirty-four in range one west, township seventy-seven north, there is a pebbly sandstone, unlike the coal measure conglomerate in the surrounding country. This sandstone is mostly brown in color, changing to yellow. It has a rather coarse texture, compared with the coal measure rocks, and is somewhat more variable in this respect. The best exposure appears in a small gully, which comes down the hill from the west, some twenty rods north of the south line of the section. In …

The August Cloud-Burst In Des Moines County, Maurice Ricker

Proceedings of the Iowa Academy of Science

It is my purpose to give merely a statement of facts concerning the storm which deluged Des Moines County the morning of August 16, 1898. I believe it was the heaviest rainfall ever noted in the United States for the period of its duration, and while the area covered was not large, it proved to be very destructive. No doubt there have been storms in which the precipitation was as heavy, where no one saw fit to chronicle the event. Many great disasters, as the Johnstown Flood, with a greater area and less precipitation, have become historic, because of loss …

The Distribution Of Loess Fossils, B. Shimek

Proceedings of the Iowa Academy of Science

It has perhaps been noted that the loess mollusks thus far reported in the literature of the subject are, for the most part, from localities in close proximity to larger streams. This fact may have suggested the thought to those unfamiliar with the modern habits and present distribution of these mollusks that the adjacent streams had in some way something to do with the entombing of the shells now found in the loess. That the loess is most richly fossiliferous near streams is generally, though not always, true. The abundance of fossils is a decidedly variable quantity. There are exposures …

The Iowa Liverworts, B. Shimek

Proceedings of the Iowa Academy of Science

Among the groups of plants hitherto neglected by Iowa botanists, the liverworts are by no means the least interesting. A few of the large thalloid species have long been familiar objects to botanists working in other fields, but the general lack of economic importance of the group, and the habits and small size of most of the species, no doubt account for the fact that they have attracted less attention than they deserve.

Buried Loess In Story County, S. W. Beyer

Proceedings of the Iowa Academy of Science

The Iowan till is not known to be present in Story County. The trend of its southwestern margin which crosses Johnson, Iowa, Tama and Marshall into Hardin County, if maintained with reasonable constancy, would carry it safely beyond the confines of the county. The loess, the silty apron of the Iowan, although suspected to be present on account of the geographic position of the area and of certain topographic contours which are decidedly loess-like in character, was not recognized certainly until during the present field season. The loess is now known to appear at numerous points along the flanks of …

New Light On The Drift In South Dakota, J. E. Todd

Proceedings of the Iowa Academy of Science

Hitherto, the writer's study of the drift of South Dakota has led him to consider it to belong mainly, if not entirely, to the Wisconsin epoch. The reasons briefly stated are as follows.

Some Physical Aspects Of General Geological Correlation, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The main object of the present communication is to formulate, briefly, certain results which have been obtained in the course of recent attempts to parallel some of the geological terranes in the Mississippi Valley. The suggestions they offer appear to have a much more than local bearing, and to affect the stratigraphy of the entire region. They also have an important influence upon the whole problem of general correlation and, perhaps, also, even upon our present system of geological classification.

A Preliminary List Of The Mosses Of Iowa, T. E. Savage

Proceedings of the Iowa Academy of Science

The mosses together with the Hepaticae or liverworts constitute the group of plants known as the Bryophytes. This group is distinguished from the Thallophytes, by the fact that they present two modes of reproduction, the sexual and the asexual, which occur in regular alternation. This gives rise to what is called alternation of generations. Most bryophytes also exhibit a very fair differentiation as between stem and leaf.

The Flora Of Southern Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick

Proceedings of the Iowa Academy of Science

On June 20, 1898, the first writer of this article started over land from Lamoni to Council Bluffs, in company with Prof. J. T. Pence. The route taken passed through the west side of Decatur County to Hopeville, in the southwest part of Clarke County, thence bearing west to Afton in Union County, on to Creston in the same county. As near as practicable the line of the Chicago, Burlington & Quincy railway was followed through Adams County, bearing southward with the railway to Villisca and northward to Red Oak in Montgomery County. From Red Oak a nearly northerly direction …

Extension Of Complex Algebra To Three-Fold Space, T. Proctor Hall

Cuesta Topography Of The Crimean Peninsula, Charles R. Keyes

Proceedings of the Iowa Academy of Science

At the last meeting of the Academy I discussed briefly some aspects of the geographic development of the Crimea and the northern borders of the Black Sea. Since that time certain of the photographs obtained by those who took part in the geological excursions following the International Congress of Geologists, have been received. It is to one of these especially that I now wish to direct your attention. It shows very clearly certain phases of the surface relief of which mention was made last year, and in a way that is rarely ever exhibited to such a great advantage or …

Permian Rocks Of Eastern Russia, Charles R. Keyes

Proceedings of the Iowa Academy of Science

In this country the Permian question has long troubled our geologists. For more than forty years it has been discussed, and up to the present time little advancement appears to have been made. Recently, interest has been awakened in the subject, and many workers have begun to attack the problems anew.
