The New Albin Inscribed Tablet, Ellison Orr

Proceedings of the Iowa Academy of Science

During the summer of 1915, workmen, in excavating for a cellar under the residence of Mr. August Welper, of New Albin, Iowa, discovered a catlinite (pipe stone) tablet with pictographs inscribed on both obverse and reverse sides, and the purpose of this paper is to set out briefly the data connected therewith.

Status Of Certain Rhynchonellid Brachiopods From The Devonian Of Iowa, A. O. Thomas, M. A. Stainbrook

Proceedings of the Iowa Academy of Science

At the first Annual meeting of the Iowa Academy of Science at Iowa City, June 23, 1876, Professor Samuel Calvin read a paper on "New Species of Paleozoic Fossils." The Proceedings of the meeting do not give an abstract of the paper but in the American Naturalist, Vol. 11, pp. 57-58, a brief abstract says that "Prof. Samuel Calvin, of the State University of Iowa, described seven New Species of Paleozoic Fossils found mainly in Howard and Floyd counties, Iowa." One of these species was Rhynchonella alta which occurs in the Lime Creek shales of Floyd …

Taxonomic Rank Of Pennsylvanian Groupings, Charles Keyes

Proceedings of the Iowa Academy of Science

When the title Pennsylvanian was first proposed for the upper subdivision of the general Carbonic section of America it was with the express purpose of designating the widely known Coal Measures by a specific geographic name, and of implying a time value to the succession represented. In an unreasonable proneness of that day amounting almost to mania, of multiplying geographic and geologic terms and of giving new geographic titles to old lithologic units future contingencies of geologic taxonomy were entirely lost sight of, and the possibilities of some more refined nomenclature at no distant date were not taken into account.

An Iowa Cambrian Eurypterid, O. T. Walter

Proceedings of the Iowa Academy of Science

Associated with dismembered parts of Dikellocephalus minnesotensis in the St. Lawrence limestone, at Lansing, Iowa, are parts of a very interesting Eurypterid. The carapace is sub-semicircular in outline; anterior margin well rounded; posterior margin broadly concave; sides diverging gently posteriorly and somewhat produced at the postero-lateral angles. The compound eyes are prominent, bean-shaped, situated about in the middle, and as far apart as their distance from the outer edge. Length, 8 mm. width, 13 mm. The species is named Eurypterus thomasi in honor of Prof. A. O. Thomas.

Behavior Of Trapped And Banded Birds, Dayton Stoner

Proceedings of the Iowa Academy of Science

In the course of certain bird-banding activities which I have been carrying on during the past several months, opportunity has been afforded for the observation and comparison of the behavior of a limited number of birds, both adult and young. And it is of some interest to note the different ways in which these "feathered bipeds" conduct themselves under the unusual conditions during and subsequent to the unlooked for disturbances connected with the operation of banding.

Sociology As A Science, Hornell Hart

Proceedings of the Iowa Academy of Science

The term "social science" appears to be taken seriously neither by scientists nor by sociologists. Conditions in social research have justified that lack of confidence, but an increasing group has set about the systematic collection of data on specific social problems and is reaching results capable of objective verification. Three recent studies of the Sociological Division of the Iowa Child Welfare Research Station illustrate this tendency. One of these measures and describes by statistical methods the selective emigration which threatens to impoverish socially certain rural areas of the state. A second study develops by means of partial regression equations the …

The Nodal Infection Of Corn By Diplodia Zeae, L. W. Durrell

Proceedings of the Iowa Academy of Science

Dry rot of corn caused by Diplodia zeae was very prevalent in Iowa the past season (1921), particularly in the central portion of the state. The disease originates in the old stubble and stalks of the previous season from which the spores of the organism are blown to the corn plants. Under conditions of extreme moisture and high temperature the spores germinate, grow and attack the corn.

A Manual Of The Gymnosperms ("Ever-Greens") Of Iowa, Both Native And Cultivated, Henry S. Conard

Proceedings of the Iowa Academy of Science

Trees or shrubs with needle-shaped or scale-like lvs, or with broad 2-lobed fork-veined lvs. The pollen falls directly upon the ovule or young seed; there is therefore no stigma or ovary. Wood close grained, without ducts (pores); "soft woods." Stam. fl. Cone-like or catkin-like, short-lived. Seeds various, with fleshy endospern. Cambium in stems and roots, forming rings of wood.

Horizontal Movement In Oblique Faulting On Inclined Strata, Charles Keyes

Proceedings of the Iowa Academy of Science

In the White Basin of southern Nevada, where extensive borax deposits were discovered a few years ago, the depression is formed by a huge drop-fault block, in which the displacement is more than 1000 feet and there appears a curious set of oblique faults which meet the major side-fault at an angle of 45 degrees. The strata being inclined about 30 degrees renders the direction of movement conspicuous. This is horizontal.

Winfield's Deep Well, J. M. Lindly

Proceedings of the Iowa Academy of Science

Winfield's waterworks system was installed in 1914. The supply of water was from a drilled well about sixty-five feet in depth. Its purpose was fire protection. Its installation was just in time to cut short several fires which, uncontrolled, would have been very destructive. Its cost was saved several times in this manner during the next few years.

Classification Of Lenses, Louise Fillman

Proceedings of the Iowa Academy of Science

This paper is the result of a bibliographic study of lenses, on the part of Lloyd North and the writer. In the literature some thirty-two genetic types are described. In the present paper these types are classified and described. A bibliography is appended.

The Rockford Geodes, S. L. Galpin

Proceedings of the Iowa Academy of Science

These geodes occur in Lime Creek shales. They are rather unusual in containing a number of roundish cavities rather than the customary rough opening. The cavities are lined with: 1. small rhombic calcite crystals which are bronzed with limonite; 2. occasional tabular and fan-shaped aggregates of barite crystals. The mode of formation is obscure.

The Effect Of Weeds Upon Crop Production, A. L. Bakke, L. H. Pammel

Proceedings of the Iowa Academy of Science

Weeds have an important bearing on the extent and the character of the crop produced. An examination of any developing crop during the growing season brings the issue to the foreground. In the case of pasture land the efficiency is much reduced by allowing weeds to grow. One of us has found that more than 39 per cent of the pastures of Iowa contain the small ragweed (Ambrosia artemesiifolia) which not only prevents the growth of blue grass but also makes it difficult for cattle to graze. What has been specifically stated for pasture land is as …

Observation On The Habits Of A Tarantula In Captivity, Albert Hartzell

Proceedings of the Iowa Academy of Science

On July 17, 1920, Mr. Robert Clark of Gilbert, Iowa presented the writer with a live female tarantula which he found in a bunch of bananas in his grocery store. He believed that the specimen must have been in hiding for several weeks prior to its capture as it was not observed until the last bananas were removed. A battery jar, with sand in the bottom, in the writer's home, served as a cage for the fifteen months the creature remained in captivity.

Structure And Function Of The Stigma In Relation To The Germinative Requirements Of The Pollen In The Easter Lily, J. N. Martin, Fred C. Werkenthin, Elizabeth Hudson

Proceedings of the Iowa Academy of Science

Stigma of Easter Lily is papillate. Over the surface of the papillae a mucilaginous layer is formed and from this mucilaginous layer the pollen absorbs the requisite amount of water for germination. The papillae and nearly all cells of the stigma previous to the opening of the flower contain much starch which is transported from cell to cell chiefly in the form of dextrin. As the starch disappears in the papillae the mucilage appears on the outside of their walls. The pollen germinates on almost any media or in almost any solution that furnishes the required amount of water.

Parry's Catalog Of Iowa Plants Of 1848, Winifred Ellsworth

Proceedings of the Iowa Academy of Science

In 1852, David Dale Owen, United States, Geologist, published his "Report of a Geological Survey of Wisconsin, Iowa, and Minnesota," and included in the volume as Article V a systematic catalog of plants of the Northwest by C. C. Parry. Parry's list bears the misleading title "Systematic Catalogue of Plants of Wisconsin and Minnesota, made in Connection with the Geological Survey of the Northwest, during the season of 1848." But in the second paragraph of Mr. Parry's explanatory introduction to his list he says, "I have also incorporated some personal observations made during a previous season in the State of …

Effects Of Stretch On Muscle Responses In The Earthworm (Helodrilus Caliginosus), B. M. Harrison

Proceedings of the Iowa Academy of Science

Much investigation has been done on the physiology of the muscles of the vertebrates as compared with that of the invertebrates. Buddington ('02) brings together the bibliography bearing on this problem, and shows that with increasing temperature Lumbricus muscle shows little constancy in changes of tone below 15° C and the first uniform result is a gradual loss of tone beginning at 20° C; rapid loss of tone occurring between 30° and 40°; an improvement from 42° to about 55° when rapid relaxation sets in, this changing to final heat rigor at about 65°.

Morphological Studies On The Injury To Apple Caused By Ceresa Bubalis, J. C. Goodwing, F. A. Fenton

Proceedings of the Iowa Academy of Science

Histological studies through lesions made in apple wood by Ceresa bubalis, the buffalo treehopper, revealed the cause of the peculiar rolling out of the wood characteristic of wounds produced by this insect. Sections were made through one, two and three year old lesions. A layer of corky tissue is formed over the wood cells that are cut by the ovipositor and exposed to the air. The two layers of corky bark adjacent to each other do not unite and this bark formation results in a wedge-shaped section of the limb being separated from the remainder. Because of this, part of …

The Structure Of The Fort Dodge Beds, James H. Lees

Proceedings of the Iowa Academy of Science

Much has been written regarding the geologic position and the stratigraphic relations of the gypsum and associated strata which are present near Fort Dodge and many are the speculations which have been put forward to account for the peculiar conditions obtaining. Observers early discovered that the gypsum was not in conformable relationship with the underlying beds and later investigators, in order to account for this situation, have enlisted various agents, even faulting in a region so little subject to diastrophism as is Iowa, having been called upon to explain such unique phenomena as may be found in the gypsum area.

A Redetermination Of The Principle Reflecting Powers Of Isolated Selenium Crystals, L. P. Sieg

Proceedings of the Iowa Academy of Science

Some time ago, following the publication of a paper by one of my former students, Mr. C. H. Skinner, I attempted to check his results by direct experiment. The paper referred to dealt with the optical constants of isolated selenium crystals. Of these constants, the reflecting power is the only one that offers itself to an easy experimental test. It must be said that the results obtained by Skinner were obtained by indirect means, and since the equations used in reducing his results to optical constants were somewhat complicated, and rested on foundations none too sure, it was important for …

A Variable Single Band Acoustic Filter, G. W. Stewart

Proceedings of the Iowa Academy of Science

This is a single band filter constructed by means of a straight tube or conduit with branch lines consisting of a volume and a tube connected in parallel and with the main conduit, but with an alteration at will of the opening into the main conduit. The narrowness of the single band can be modified by the modifications in the size of this hole without seriously affecting its other characteristics. The performance of the single band filter reported upon is in accord with theory mentioned.

Solubility And Polarity, Wm. Kunerth

Proceedings of the Iowa Academy of Science

Since the phenomenon of solubility is one of such common occurrence and universal familiarity, it is no wonder that a great many attempts have been made to learn the cause of it. The molecular weight of solute and solvent, the dielectric constants, the size of the molecules concerned, the surface tensions of the components, adsorption, the vapor pressure above the solution, the magnitude of Van der Waal's a and b for the components, their internal pressures · as determined by a great many different methods - all these and many other avenues of approach have been used, only to be …

A New Kind Of Telephone Reciever And Transmitter, C. W. Hewlett

Proceedings of the Iowa Academy of Science

The Tone Generator described in these proceedings a year ago has been used successfully as a telephone transmitter and receiver. A loud speaker about eight inches in diameter has been made which will speak loudly enough to address a small gathering of people, say a hundred. The main advantage of the instrument is its faithfulness of reproduction of speech and music, the failure to do which is the chief disadvantage of all other known telephone instruments. The instrument when used as a transmitter is free from all the usual transmitter noises, and from distortion due to resonance of the diaphragm.

The Attenuation Factors In Acoustic Wave Filters, H. B. Peacock

Proceedings of the Iowa Academy of Science

A theory has been formulated by Dr. G. W. Stewart by which it is possible to determine the selective transmission in three types of specially constructed acoustic wave filters. The theoretical attenuation factor also has been worked out and shows fair agreement with experimental results. Theoretical values of the attenuation were computed for one filter of each type and, from these values, the theoretical transmission curves were determined. The types of filters were the low-frequency and high-frequency— pass, and the single band.

A Scribofacilograph For Labeling Kymographic Tracings, T. L. Patterson

Proceedings of the Iowa Academy of Science

The ordinary laboratory routine of labeling kymographic tracings involves at best a rather tedious and arduous task which consists either of holding the hand unsupported well above the carbonized paper and writing upon it with a stylus in the form of some pointed instrument, or writing over the rod of an iron stand or some other inconvenient support for the hand. Furthermore, the carbonized paper must be securely held and especially where there are drafts of air while the labeling is being done, and as a result the fingers become coated with carbon, so that notebooks, clothing, etc., which are …
