The Lower Rapids Of The Mississippi River, Frank Leverett

Proceedings of the Iowa Academy of Science

In the early days of navigation on the Mississippi, two important rapids were found to interrupt the passage of vessels at low water stages; one, about fifteen miles in length, being above the city of Rock Island, Ill., and the other, about eleven miles in length, above the city of Keokuk, Iowa. These became known, respectively, as the upper and lower rapids. The latter are also called the Des Moines rapids because of the situation above the mouth of the Des Moines River.

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.

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. …

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.

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 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 Weathered Zone (Sangamon) Between The Iowan Loess And Illinoian Till Sheet, Frank Leverett

Proceedings of the Iowa Academy of Science

The Illinoian till sheet here discussed was formed by the Illinois glacial lobe in connection with the maximum extension of that lobe. It seems quite well established that a lobe on the east, which covered southeastern Indiana and southwestern Ohio, and extended a short distance into Kentucky, also had its culmination at the Illinoian stage of glaciation. Farther east the Wisconsin sheet in many places reaches the glacial boundary, but there are small tracts of drift older than the Wisconsin, lying outside its limits in eastern Ohio, northwestern and northeastern Pennsylvania, and northern New Jersey, which may prove to be …

A New Species Of Daphina, And Brief Notes On Other Cladocera Of Iowa, L. S. Ross

Proceedings of the Iowa Academy of Science

A few collections taken from West and East Okoboji Lakes and Spirit lake in June, and from the sloughs of the Des Moines River in the fall of 1886, have added six more species to the list of Cladocera in the state, as given in the ''Proceedings" of the Academy for 1895. Five of the species are common to the country, and one is a hitherto undescribed species of Daphnia. A few individuals of a form of the difficult genus Bosmina were found which may be the young of Bosmina longirostris, O. F. Muller. If not the young of …

Contributions To The Hemipterous Fauna Of Iowa, Herbert Osborn, E. D. Ball

Proceedings of the Iowa Academy of Science

In various papers published during the past five years the senior author has called attention to the injuries caused in grass lands and pastures by the numerous species of Jassidae, which swarm, often by millions to the acre, upon various species of grasses.

Evidence Of A Sub-Aftonian Till Sheet In Northeastern Iowa, S. W. Beyer

Proceedings of the Iowa Academy of Science

Until very recently, geologists working in Iowa have been content to refer the various boulder clays represented in the state to two till sheets, a so called "upper" and "lower," separated in many places by the "forest beds" of McGee, or in other localities by gravels, often in conjunction with a vegetal horizon, the Aftonian of Chamberlin.

Waverly Phoenix, January 2, 1895

Waverly Phoenix

The Waverly Phoenix was a Democratic weekly German-language newspaper published from 1884 to 1924 in Waverly (Bremer County), Iowa. Articles in the newspaper reflect the experiences and viewpoints of first- and second-generation German immigrants who had settled in Iowa.

Some Facts Brought To Light By Deep Wells In Des Moines County, Iowa, Francis M. Fultz

Proceedings of the Iowa Academy of Science

During the past year a number of deep wells were sunk in Des Moines County. Some of them reached such extraordinary depths before touching rock, or without touching rock at all, as would clearly show the presence of buried river channels. In a paper presented before this society a year ago I stated that the pre-glacial and present drainage systems in this region were practically the same. From facts recently brought to light I must necessarily change that opinion. To what extent remains yet to be seen.

Inoculation Experiments With Gymnosporangium Macropus Lk., F. C. Stewart, G. W. Carver

Proceedings of the Iowa Academy of Science

The family of true rusts, Uredineae, is very interesting to the mycologist and important to the agriculturist. It contains about twenty-seven genera and a multitude of species, all of which are strict parasites, living within the tissues of their hosts. Several of the species produce destructive diseases in cultivated plants; as examples note the rust of wheat, oats and other grasses (Puccinia graminis, Pers.), blackberry rust (Caeoma luminatum, Schw.), and carnation rust (Uromyces caryophyllinus [Schrank], Schroeter). Thus far all attempts to cultivate the rusts upon artificial media have failed.

Homologies Of The Cyclostome Ear, H. W. Norris

Proceedings of the Iowa Academy of Science

The ear of the Cyclostomata has until recently been considered so peculiar as to render it difficult to explain its relations to the typical Vertebrate ear. Then again, the diversity of structure in the auditory organ of the Cyclostomes themselves renders the task of homologizing the various parts somewhat uninviting.

The Reduction Of Sulphuric Acid By Copper As A Function Of The Temperature, Launcelot W. Andrews

Proceedings of the Iowa Academy of Science

The object of the experiments described in this paper was to determine whether the reduction of sulphuric to sulphurous acid by copper takes place at a lower or at a higher temperature than the incipient dissociation of the former compound into water and the acid anhydride.

Recent Discoveries Of Glacial Scorings In Southeastern Iowa, Francis M. Fultz

Proceedings of the Iowa Academy of Science

The discoveries of localities showing glacial scoring in southeastern Iowa have been somewhat numerous during the last few years. In a paper presented before this body a year ago I called attention in detail to the different known exposures of glaciated rock in this region, and pointed out that the testimony they gave was unanimous as to the southeastern movement of the ice sheet. Since then another exposure has been located that seems to bring conflicting testimony.

Notes On Forest Distribution In Iowa, T. H. Macbride

Proceedings of the Iowa Academy of Science

The peculiar character of our American forest geography early attracted the attention of intelligent observers. Civilized men, Frenchmen, crossing the continent from the Atlantic seaboard, after threading for two hundred leagues a forest almost unbroken, suddenly found themselves in the presence of vast treeless plains, extending westward across a large portion of the central Mississippi Valley. In wonder and admiration the voyageur looked upon these great plains, grass-grown and flower-bedecked, and found them counterpart to the green meadows of France; to them he gave the name prairie, a word now so familiar as to have long lost for all English-speaking …

Distribution Of Some Weeds In The United States, Especially Iva Xanthifolia, Lactuca Scariola, Solanum Corolineum And Solanum Rostratum, L. H. Pammel

Proceedings of the Iowa Academy of Science

One of the interesting parts dealing with geographical botany is the question of the distribution of plants over the earth's surface, where man has played an important part. Many changes have occurred in the character of our North American flora since it has been occupied by man. In many cases it has become quite impossible to tell when and where plants were first introduced. We have, it is true, in some cases records when plants were introduced, but in the vast majority of cases there were no records at hand. Early collectors in many cases simply mentioned vague localities with …

Diseases Of Plants At Ames, 1894, L. H. Pammel

Proceedings of the Iowa Academy of Science

To fully discuss the fungus diseases of plants we should consider all matters that have a bearing on the question. One of the most essential conditions is the character of the weather. The relative humidity and precipitation are very important factors in the development of fungi. The germination of spores depends largely on the humidity of the atmosphere.

Bacteria, Their Relation To Modern Medicine, The Arts And Industries, L. H. Pammel

Proceedings of the Iowa Academy of Science

It has been customary for the president in making his retiring address, to choose some popular subject and discuss it on broad lines. In some cases my predecessors have given a resume of the scientific literature in our own State, and I need not say that we all feel proud of the work accomplished by this small band of workers. I shall venture, in this address, to discuss the subject of Bacteria along general lines and hope I may be able to correct some popular misapprehensions concerning the subject.

Electrolysis Of Silver Laboratory Notes, W. S. Hendrixson

Proceedings of the Iowa Academy of Science

The author exhibited some pieces of apparatus devised in connection with his work on the atomic weight of tin, and also a quantity of pure silver prepared by electrolysis of the pure silver of Stas in strong nitric acid solution. The method of electrolysis was essentially that of Abrahall as modified by Richards. By using a strong acid solution containing fifteen per cent of silver and a battery consisting of sixteen gravity cells the silver was obtained in large crystals and no peroxide was formed at the positive pole. Separate experiments showed that silver deposited under these conditions, from a …

Some Peculiarties Of Solutions Of Ferric Sulphocyanate, Launcelot Andrews

Proceedings of the Iowa Academy of Science

The deep blood-red color of solutions of ferric sulphocyanate has frequently been taken advantage of for the determination of small quantities of iron in river or spring water, in blood; in alloys, in alumcake, etc. The earliest method of this kind so far as I have been able to ascertain, is due to T. L. Herapath, who proposed to determine minute quantities of iron by the addition of potassium sulphocyanate to the acidified solution containing an unknown amount of iron, and also to a standard iron solution of known strength, the latter being then diluted until both showed the same …

The Tertiary Silicified Woods Of Eastern Arkansas, R. Ellsworth Call

Proceedings of the Iowa Academy of Science

The occurrence of silicified wood in the sands and gravels of the Tertiary of the Lower Mississippi Valley has long been known. Aside, however, from the numerous localities mentioned by Hilgard, nearly all of which are in the State of Mississippi, little attention has been given it. Numerous geologists have spoken of it or incidentally studied it in connection with other investigations, but hitherto no attempt has been made to recognize the species and fix their taxonomic value, if, indeed, they possess any such value. Among those who have investigated the Orange Sands and other Tertiary deposits of the Mississippi …
