The Distribution Of Forest Trees In Iowa, B. Shimek
The Distribution Of Forest Trees In Iowa, B. Shimek
Proceedings of the Iowa Academy of Science
The discussion of the origin of our prairies, and of the distribution of our native forest trees, is as old as our knowledge of the central northwest. The earlier discussions were based on a knowledge of conditions as they existed when the white man first appeared in this section, and, though some of them are crude, and based upon insufficient observation, they fortunately give us at least a partial record of those conditions.

The Genus Salix In Iowa, Carleton R. Ball
The Genus Salix In Iowa, Carleton R. Ball
Proceedings of the Iowa Academy of Science
The genus Salix has long and justly been considered a difficult one to study. It is not that the genus is so large, there being only some 200 living species known, or that these species are so variable in themselves, although a few of them are known to be very much so. The chief difficulty lies in the dioecious character of the plants, and the fact that in the majority of the species the flowers are produced before the leaves appear, or at least before they are large enough to become characteristic.

Presidential Address - Some Features Of The Science Of A Hundred Years Ago, W. S. Hendrixson
Presidential Address - Some Features Of The Science Of A Hundred Years Ago, W. S. Hendrixson
Proceedings of the Iowa Academy of Science
In the past three or four years the popular magazines have contained numerous articles on the progress of science in the nineteenth century. These papers were written for popular information and they deal with only a few great discoveries with which all men of science are familiar. It occurred to the writer that for the entertainment and information of the man of science, who is acquainted with the main facts and theories of every science as it is to-day, and who, though not acquainted with its minute details, is at least aware of its great mass of facts, its intricate …
The New School Of Animal Psychology, C. C. Nutting
The New School Of Animal Psychology, C. C. Nutting
Proceedings of the Iowa Academy of Science
The title of this paper is in one sense a misnomer, from the fact that the prophets of the new school are inclined to deny any real psychology to animals. According to Morgan, mind is the wave of consciousness in its continuity. Thorndyke says that "The mental stream is not continuous in animals," If this is true, animals cannot be said to have minds, and hence animal psychology cannot exist.

The Scydmaenidae And Pselaphidae Occurring Near Iowa City, Iowa, H. F. Wickham
Proceedings of the Iowa Academy of Science
The minute beetles belonging to the above families have been much neglected by collectors, although their many peculiarities of habit and structure make them well worthy of attention. For three years past my wife and I have collected them systematically in this vicinity, with the result of very largely increasing the list of species known to occur here.
A Notable Ride - From Driftless Area To Iowan Drift, Samuel Calvin
A Notable Ride - From Driftless Area To Iowan Drift, Samuel Calvin
Proceedings of the Iowa Academy of Science
There is in eastern Iowa one short journey which shows a more interesting variety of land forms in small space than can be seen almost anywhere else. It shows too, in a typical way, the different surface aspects of areas belonging respectively to the driftless area and to the plains of Kansan and Iowan drift. For these reasons the journey referred to should become famous, and might well become a standard in certain particulars, among students of Pleistocene deposits and topographic forms. The journey is over the Illinois Central railroad; it begins at Dubuque, and it may end at Dyersville. …
Formational Synonomy Of The Coal Measures Of The Western Interior Basin, Charles R. Keyes
Formational Synonomy Of The Coal Measures Of The Western Interior Basin, Charles R. Keyes
Proceedings of the Iowa Academy of Science
Of late years the Carboniferous terranes, or formations of the Mississippi basin west of the great river have been widely studied. They are now capable of being classified in detail. For a long time much confusion existed in regard to the relations that the schemes of various investigators, and especially those of the pioneers, bore to one another, and to the more modern widely correlated arrangement. The adjustment of the results of all workers, extending over a period of fifty years, in a field embracing the greater part of six states, was fraught with many difficulties.
An Abnormal Fermentation Of Bread, C. H. Eckles
An Abnormal Fermentation Of Bread, C. H. Eckles
Proceedings of the Iowa Academy of Science
During the past summer my attention was called to a peculiar abnormal condition which the bread baked in the house underwent a few days after baking. About the same time complaints were made by a number of residents of the town regarding the same trouble. A number of inquiries were also noticed in the magazines, devoted to the household, indicating the trouble was present in other localities. Inquiry among neighboring housekeepers showed that while most of them had never heard of such a trouble with bread, a number of them had seen the condition or known of someone who had …
Additions To Lichen Distribution In The Mississippi Valley, Bruce Fink
Additions To Lichen Distribution In The Mississippi Valley, Bruce Fink
Proceedings of the Iowa Academy of Science
During the last few years I have examined a large number of lichens from various parts of the Mississippi Valley, and a few of these have never been recorded from the states in which they were collected, either in my own papers, or, so far as I know, in other publications. In a paper read before the botanical section of the A.A.A.S. at the Columbus meeting I made mention of some of these plants, but several are of special interest because rare or difficult to detect, and I have thought it worthwhile to record all for distribution. Aside from a …

Basidiomycetae Of Central Iowa, Alice Ward Hess, Harriet Vandivert
Proceedings of the Iowa Academy of Science
A number of investigators have listed the Phanerogams in different parts of the state. There are, however, only a few lists of the Saprophytic fungi of the state. Bessey under the head of "Preliminary list of Carpophytes of the Ames Flora" lists quite a number of species and Macbride also makes a contribution along this line, especially the species found by him in eastern Iowa.
The Orchidaceae Of Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick
The Orchidaceae Of Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick
Proceedings of the Iowa Academy of Science
The Orchidaceae comprises 5,000 species distributed among 410 genera. The species are mostly tropical but are found in temperate climates, one as far north as the 68th degree of latitude. The orchids are of especial interest to lovers of flowers because of their great beauty, peculiar forms, sweet fragrance and strange habits, and are great favorites with floriculturists in the old world as well as in the new.

The Genus Viburnum In Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick
Proceedings of the Iowa Academy of Science
Our Viburnums are few in number of species and rapidly becoming scarce in the number of individuals. They are to be found in the wooded portions, mostly eastern, of the state. The fruits of some are edible but have not been considered promising enough to warrant cultivation.

Klebs-Leoffler Bacillus, Gershom H. Hill
Proceedings of the Iowa Academy of Science
This is a scientific age. The use of scientific methods in the vocation by which a man gains a livelihood makes it both interesting and profitable. The scientific man realizes the necessity of telling the truth, the whole truth and nothing but the truth. Scientific work makes a man careful, accurate and a close observer. The scientific American is somewhat different from the scientific German. The former places a high cash value on his time; he is intensely utilitarian. The geologist is expected to furnish the cities with clay and coal to make brick for paving and for other purposes. …

Trees And Shrubs Of Hamilton County, H. A. Mueller
Proceedings of the Iowa Academy of Science
Hamilton County is the fourth from the north and the sixth county from the Missouri River, thus placing it in the north central portion of Iowa. The county is a distinctly prairie country, situated on a level divide between the Des Moines river on the west and Iowa river on the east, neither stream touching the borders of the county.

Notes On The Hemiptera Of Northwestern Iowa, Herbert Osborn
Notes On The Hemiptera Of Northwestern Iowa, Herbert Osborn
Proceedings of the Iowa Academy of Science
From the difference in geological and floral conditions of the northwestern part of the state, we might naturally expect a somewhat interesting insect fauna. Occasional specimens of species, rare or unknown in the central part of the state, have come to hand and, especially in Hemiptera, have served to strengthen a desire to investigate more thoroughly the fauna in this order. Many of these additions have been due to the successful collecting of Mr. E. D. Ball, whose faithful, persistent efforts it is a pleasure to acknowledge here. During the summer of 1897 I spent a couple of weeks in …
Forest Trees Of Adair County, Iowa, James E. Gow
Forest Trees Of Adair County, Iowa, James E. Gow
Proceedings of the Iowa Academy of Science
In order to understand the forestry conditions of Adair County, a short description of the lay of the land and the nature of the soil is first necessary. The county lies along the crest of the "grand divide," between the Mississippi and the Missouri, so that a line drawn along the crest of the ridge traverses it diagonally from northwest to southeast. The land is undulating enough to secure an easy natural drainage, but not so undulating as to be difficult of cultivation, except in a few isolated localities. The soil is a rich, black loam, varying in thickness from …

A Simple Incubator, L. S. Ross
Proceedings of the Iowa Academy of Science
No claim of originality is made in the presentation of the description of the simple apparatus used by me as an incubator. The idea, so far as I know, originated in the mind of Mr. W. D. Frost, assistant instructor in bacteriology in the University of Wisconsin.

Effects Of A Sleet Storm On Timber, James E. Gow
Effects Of A Sleet Storm On Timber, James E. Gow
Proceedings of the Iowa Academy of Science
On the night of the 9th and the morning of the 10th of February, 1898, a heavy sleet storm passed over Adair County, Iowa. The storm began not very long after midnight with a brisk rain which froze as it fell and adhered tenaciously to trees and other objects with which it came in contact. The wind at the time was slightly west of north and was not blowing at all briskly. The day preceding the storm had been unusually warm, for the time of year, with a cloudy sky, a slight breeze from the north and a very humid …

The Burlington Artesian Well, Francis M. Fultz
Proceedings of the Iowa Academy of Science
Work was commenced on the Burlington artesian well about midsummer of 1896; but, owing to cessation of operations for somewhat more than a year, it was not finished until midsummer of 1898. The well is located in Crapo Park, and the expense of putting it down was borne out of the park funds.
The Lower Rapids Of The Mississippi River, Frank Leverett
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.
