The Distribution Of Forest Trees In Iowa, B. Shimek Jan 1899

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 Jan 1899

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.

Native Crab Apples And Their Cultivated Varieties, John Craig, H. Harold Hume Jan 1899

Native Crab Apples And Their Cultivated Varieties, John Craig, H. Harold Hume

Proceedings of the Iowa Academy of Science

Indigenous to North America there are several species of Pyrus belong to the Malus or apple group. Sargent, in his Silva of North America, gives three species and one variety. These are P. rivularis Doug., found west of the Rocky Mountains from northern California to Alaska; P. angustifolia Ait., ranging from Pennsylvania to Tennessee and Florida; P. coronaria L., in the region from New York to Michigan, southward and westward to Missouri and Kansas; P. coronaria var. Iowensis, Wood, confined to the prairie states. In the American Garden, XII, 473, 1891, Professor Bailey raised var. Iowensis to specific rank, basing …

Presidential Address - Some Features Of The Science Of A Hundred Years Ago, W. S. Hendrixson Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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 Jan 1899

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. …

Notes On The Hemiptera Of Northwestern Iowa, Herbert Osborn Jan 1898

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 Jan 1898

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 Jan 1898

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 Jan 1898

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 Jan 1898

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.
