Experiments With Soy Bean Meal As A Substitute In The Army Ration, Arthur W. Dox Capt.

Proceedings of the Iowa Academy of Science

The use of soy beans for human food has of late been the subject of a number of scientific investigations. The literature is not available to the writer at the present time, hence will not be discussed in this brief paper. The nutritive value of soy beans has, however, been established, and a future for this commodity as an article of human food is almost certain. The Chinese and Japanese have used soy beans for many years and prepared them in quite a variety of ways. In our own country little is known of soy beans except as a forage …

Pre-Glacial Moingona River, Charles Keyes

Proceedings of the Iowa Academy of Science

As Iowa's master waterway, the Des Moines River rises beyond the extreme northwest corner of our State, and flows entirely across it to the southeast corner. The name is the oldest term applied by Europeans to any feature of the territory. As such the title is derived from the Moingona Indians whom Jolliet and Marquette, commonly ascribed discoverers of the Mississippi, found in the summer of 1673 located near the river's mouth.

Some Features Of The Fort Dodge Gypsum, James H. Lees

Proceedings of the Iowa Academy of Science

During the prosecution of field study of the gypsum for the Iowa Geological Survey the writer found immediately beneath the gypsum in several places a basal conglomerate which has not heretofore been described in reports on the region. The locality where this conglomerate is best developed is in a ravine on the west side of Des Moines River opposite Two Mile creek about three miles south of Fort Dodge. The Fort Dodge, Des Moines and Southern railway extends along this ravine and has exposed the conglomerate in some of its cuttings.

Notes On Some Iowa Rodents, Dayton Stoner

Proceedings of the Iowa Academy of Science

During portions of the past three summers some investigations of the rodents of Iowa have been made under the auspices of the Iowa Geological Survey. These studies have been carried on more particularly in an attempt to determine the economic status of this group of animals in the state but other phases of the work such as matters of distribution, local abundance, etc., of the various species have also been included.

Some Additional Notes On Pollination Of Red Clover, L. H. Pammel, L. A. Kenoyer

Proceedings of the Iowa Academy of Science

Many years ago Charles Darwin conducted some experiments to determine whether red clover is self-fertile. This investigator found that when insects were excluded, red clover did not produce a single seed, while flowers exposed to insects produced an average of twenty-seven seeds per head. The experiments of Darwin and many of the older investigators who conducted experiments with red clover were faulty since they did not release the anthers from the keel.

Influence Of Orchard Soil Management On Fruit Bud Development And Formation As Found In The Apple, R. S. Kirby

Proceedings of the Iowa Academy of Science

Since this is merely a progress report on fruit bud development, it is impossible to draw definite conclusions, as insufficient data have been compiled.

The Thermal Conductivity Of Tellurium, Arthur R. Fortsch

Proceedings of the Iowa Academy of Science

Until September, 1915, when this research was undertaken, no work had been done on the thermal conductivity of tellurium. During the year 1915-1916, however, King in collaboration with Wold published some work on tellurium in which values were given for its thermal conductivity. In this article will appear: (1) A brief outline of the method used by the author, which was entirely different from that of Wold and King; (2) A summary of the results obtained by this method; and. (3) A comparison between these results and those of Wold and King.

Second Record Of Oscillations In Lake Level, With Record Of Lake Temperature And Of Meteorology, Secured At The Macbride Lakeside Laboratory, Lake Okoboji, Iowa, July, 1916, John L. Tilton

Proceedings of the Iowa Academy of Science

In the ''Proceedings of the Iowa Academy of Science'' for 1916 may be found a somewhat similar title for a paper in which data obtained in July, 1915, were discussed. It is the purpose of the present paper to present the records of a second year. These records were obtained in part for personal information, and in part for reference by students at the laboratory. It is believed that the records (and also those of last year) are sufficiently accurate for use by those studying the limnology of the lake and possibly by those who may work on the heat …

The Loess And The Antiquity Of Man, B. Shimek

Proceedings of the Iowa Academy of Science

Reports on the antiquity of man in Europe and on both the American continents, contain frequent references to loess, and repeated efforts have been made to establish the antiquity of man on the basis of the relation of human remains and artifacts to supposed loess. Such efforts have been uniformly unsuccessful, and the weakness of these cases has resulted chiefly from the following causes.

The Prairie Du Chien - St. Peter Unconformity In Iowa, Arthur C. Trowbridge

Proceedings of the Iowa Academy of Science

Unconformable relations between the Prairie du Chien and St. Peter formations have long been known in Minnesota, Wisconsin, Illinois and Missouri. The existence of this unconformity in Iowa, though long suspected, has never been demonstrated, or if it has been known to exist here, the fact has not been recorded. There is nothing in the reports of the State Geological Survey suggesting anything but conformable relations between the two formations.

Effect Of Drawing On The Density And Specific Resistance Of Tungsten, Wm. Schriever

Proceedings of the Iowa Academy of Science

It is known that the density of ductile tungsten wire changes when the wire is drawn to smaller diameters but the results of several experiments do not agree as to the nature of the variation. Fink (Trans. Amer. Electro. Chem. Soc., 17, p. 229, 1910) gives data to show that the density increases with the drawing, the variation being 18.81 g/cm³ before drawing to 20.19 g/cm³ when drawn to a diameter of 0.038 mm. His method of measurement was not described. Doctor Sieg, in working with a number of tungsten wires, also found an increase of density with …

The Protein Content And Microchemical Tests Of The Seeds On Some Common Iowa Weeds, L. H. Pammel, Arthur W. Dox

Proceedings of the Iowa Academy of Science

Weed seeds are recognized as an important factor in the dietary of our useful birds. Other things being equal, those seeds having the highest nutritive value might be expected to figure more prominently in this regard than seeds less nutritious. In animal feeding, the protein content of the feed is taken as the measure of its nutritive value, and the cost of the feed is determined largely by the protein content as ascertained in the chemical laboratory. Hence the protein content of weed seeds is of some economical importance as related both to the maintenance of our native birds and …

Extent And Age Of Cap-Au-Gres Fault, Charles Keyes

Proceedings of the Iowa Academy of Science

On the general geological map of Iowa there are three peculiarities in the areal distribution of the geological formations represented which excite particular attention. They indicate that not only has the terranal story not been yet all told but that owing to unusual misinterpretation the real facts have been unwittingly greatly distorted. One of these features is the notable southeastward straight trend of the eastern border of the basal Missourian, or Bethany, limestone as it leaves our state in Wayne County - a direction nearly at right angles to that which we would ordinarily expect.

Post-Kansan Erosion, M. M. Leighton

Proceedings of the Iowa Academy of Science

Visitors to the Maquoketa River gorge below Monticello in Jones County have been impressed with its rocky walls of the Niagaran formation which rise in places 100 to 125 feet above the stream. Overlying this rock formation are drift and loess. Crags, turrets, and chimney rocks, similar to the rugged features of the valleys of the driftless area, appear here and there. In fact, the characteristics of this gorge are so nearly like those of the valleys of the driftless area that in the report of the Geology of Jones County the gorge is considered to be pre-glacial in age.

Some Fundamental Concepts Of Earth History, James H. Lees

Proceedings of the Iowa Academy of Science

We have been accustomed to think, most of us, that in the early days of the world's geologic history Nature manifested herself in forms different from those with which we are familiar; that God, the supreme Power of the universe, employed other types of energy than those by means of which He works today. And these conceptions have been fostered and influenced very largely, consciously or unconsciously, by our religions and theological training.

The Bermudas As A Type Collecting Ground For Invertebrates., H. A. Cross Jr.

Proceedings of the Iowa Academy of Science

Eighty hours from Chicago lands one at the Wharf of Hamilton in the Bermuda Islands. Temporarily these islands are near, although 700 miles southeast from New York. And 560 miles due east from Charleston, South Carolina. Topping the summit of a huge submarine mountain, built up by the secretion of corals, shifted, torn down, and stratified by the action of wind and wave, these islands project to the number of one hundred and fifty, forming nineteen square miles of land whose surface is a thin ten inch layer of red brown soil. In the aggregate, these islands assume the form …

Further Notes On The Venous Connections Of The Lymphatic System In The Common Rat, Thesle T. Job.

Proceedings of the Iowa Academy of Science

As long ago as 1825 the Italian anatomist, R. Lippi, published a paper on “Illustrazioni fisiologiche e patologiche del sistems linfalico-chilifero mediante la scoperta di un gran numbero di comunicazioni de esso col venoso” in which he brought out the fact that the lymphatics not only connect with the veins at the Jugulo-subclavian juncture but also join the Inferior Vena Cava and Portal vein. 49. Mites affecting-According to the plan of nature animals are compelled either directly or indirectly to lay under tribute the plant world in order to obtain food; and so completely have they done so that it …

Chlorotic Corn (A Progress Report), W. H. Davis

The Electromotive Force And Free Energy Of Dilution Of Lithium Chloride In Aqueous And Alcoholic Solutions, J. N. Pearce, F. S. Mortimer

Proceedings of the Iowa Academy of Science

Various experimental methods may be employed for comparing the activities of solutions of electrolytes, viz., freezing point, boiling point, vapor pressure, osmotic pressure, electrical conductivity and electromotive force. Of these, the latter is generally more convenient of application; it has the advantage in that measurements are more easily made and its use is not restricted to any particular temperature interval. In solutions ranging from the moderately dilute to the very concentrated it may be applied more accurately than the conductivity method. The electromotive force method, however, has its limitations. It shares with all of the other methods the disadvantage of …

The Aecial Stage Of Alsike Clover Rust, W. H. Davis

Proceedings of the Iowa Academy of Science

A rust belongingg to the genus Uromyces is rather prevalent in this latitude on the common clovers, white (Trifolium repens L.), red (Trifolium pratense L.) and alsike (Trifolium hybridum L.). The rusts on clovers were formerly classified as a single species or one rust until the work of Liro separated them into two species, one on red and one on white clover. The disposition of the rust on alsike clover is not clear.
