Forestry In Iowa, B. Shimek

Proceedings of the Iowa Academy of Science

A paper on forestry in Iowa might be condensed in the form of a paraphrase of the schoolboy's essay on "Snakes in Ireland," — "there is no forestry in Iowa," —at least none in practice, though the need of the practical application of its principles may be seen in every township of land in the state.

Some Improved Laboratory Devices And Apparatus, A. A. Veblen

Proceedings of the Iowa Academy of Science

The base of the model is a plain board 26 by 9 inches. At the rear edge of this is another board 5 inches wide, set on edge, A, Fig. 1. To the upper edge of the latter are hinged 27 metal rods A D, 8 inches long. The front ends of the rods are free to move up and down in vertical slots C, and each carries a white disc D half an inch in diameter, which is soldered at its center to the end of the rod, and at right angles with it. Approximately simple harmonic motion is …

The Sanitary Analyses Of Some Iowa Deep Well Waters, J. B. Weems

Proceedings of the Iowa Academy of Science

In the investigation of deep well waters the interest in many cases has been limited to the mineral substances, and little attention given to the sanitary analysis. This is a natural result when it is realized that these waters contain large amounts of solids and the possibility of contamination by sewage or other products is very slight indeed. In connection with the work of the Department of Agricultural Chemistry of the Agricultural College, analyses of a number of samples of water from the deep wells of the state have been made and the results brought together in hope that they …

The Chemical Composition Of Sewage Of The Iowa State College Sewage Plant, J. B. Weems, J. C. Brown, E. C. Myers

Proceedings of the Iowa Academy of Science

The sewage plant of the college was constructed in 1898 from the designs and under the supervision of Prof. A. Marston, the college engineer. The plans and a short description of the work of the plant have been recently published and only the chemical investigations will be considered in this paper.

Calcium Carbide As A Dehydrating Agent For Alcohols, Alfred N. Cook, Arthur L. Haines

Proceedings of the Iowa Academy of Science

It is well known that almost all alcohols purchased in the market contain considerable water. It varies from five per cent to fifteen per cent in methyl and ethyl alcohols and is less in amyl and other alcohols. It was thought that it would be interesting and profitable to determine the degree of dehydration produced by the action of calcium carbide on the water in these alcohols.

Igneous Rocks Of The Central Caucasus And The Work Of Loewinson-Lessing, Charles R. Keyes

Proceedings of the Iowa Academy of Science

In view of the widespread interest that the subject of the differentiation of rock-magmas is exciting among geologists generally I am led at this time to call your attention to one of the most recent, and at the same time one of the most important contributions which has yet been made. My notice will be brief, and will consist chiefly of an exhibition of specimens of many of the most notable rock types. An explanation of some of the most significant features will be given. Photographs of some of the most characteristic rock-masses as they appear in the field will …

Evidences Of Recent Uprisings Of The Shores Of The Black Sea, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The photographs which I have to show you are to illustrate some remarkably clear examples of very recent changes in elevation of the earth's crust. Most of the pictures were taken in the neighborhood of Sudak, in the Crimea. The southern coast of this peninsula is very rugged. It rises abruptly out of the water to a height of 3,000 to 5,000 feet. The waves are constantly eating back so that in many places the coast land is almost a sheer precipice hundreds of feet high.

On The Occurrence Of Rhizopods In The Pella Beds In Iowa, J. A. Udden

Proceedings of the Iowa Academy of Science

In Jefferson County the Pella beds of the Saint Louis formation have a thickness of about twenty feet. They consist of heavy ledges of calcareous limestones, interbedded with seams of marly shales, the latter being best developed in the upper part of the section. The several seams and ledges appear quite persistent and some have been identified at different points a few miles apart. They have evidently been laid down at some considerable distance from the shore. Occasionally there are ledges of limestone which are very fine-grained, almost lithographic in texture. Here as elsewhere in the south part of the …
