This article discusses the interrelations of demand for selected agricultural products in the U.S. A direct attack on the problem of interrelated demands seems possible by use of simple graphic methods and charts which relate the ratio of prices of two commodities to the ratio of their quantities. If the quantity of beef consumed rose in comparison with the quantity of pork consumed, then it would not be unreasonable to expect the price of beef to fall in comparison with the price of pork. This article presents some illustrative use of charts of this type for meats, certain fruits, and grains. There are certain readily observable characteristics of the demand for meat which lead to an expectation of certain statistical relations between their demand curves, or to expectations regarding substitution curves. Meat plays a definite part in the diet of most people in the U.S. Observation of common food habits leads to the conclusion that total meat consumption is probably influenced by price, most consumers being willing to vary their meat purchases within fairly wide limits as prices change. In the western U.S., pork production is less than consumption, and beef is consumed in greater quantity than is pork.

The article discusses the economic prognosis of foreign exchange controls. Countries having an export surplus consisting chiefly of agricultural products will discover that their agriculture languishes. Industry will gain in the relative cheapness of imported raw materials at the low official rate on foreign devisen. The automatic protection afforded through the scarcity of raw materials at low rate, the high domestic prices chargeable for products and the cheapness of domestic agricultural materials.

The article evaluates the regulation of the wheat and flour trade by the U.S. Food Administration. The agency is tasked to fix the price of wheat and its maintenance for an entire crop year. Another responsibility of the agency is in the control and regulation of the distribution of the available wheat supply. Also, the flour milling industry needs stabilization by a public authority which was provided by the agency. Herbert C. Hoover announced the priorities of the agency which includes the monitoring of exports so as to retain sufficient supplies of foodstuffs within the country for domestic use.

The article provides information about Boyce Thompson Institute for Plant Research Inc. in New York. The institute was established in 1924 and designed for the investigation of the basic principles underlying food and fiber production. It was spearheaded by researcher W. B. Thompson, who provided an endowment of about $11 million to create the facilities and support the staff. In 1970, the research center was operating on a budget of $2,640,000, which maintains a staff of 37 senior scientists, 50 nonscientists in clerical and horticultural services.

The article focuses on the issues concerning the public image of plant pathology in the U.S. It cites that industrial concerns engaged in research, development, and sales of agricultural pesticides and processors of food and feed are concerned about the public image of all agricultural disciplines. According to the article, the Department of Agriculture exercised leadership to sustain efforts in creating a better public image and understanding of agriculture. It further states that the public has little knowledge on the concept of what a plant pathologist is or the contribution he makes to the public.

The article discusses the role of U.S. bioscientists in developing the new agricultural technology that has helped in the increase of food production across the world. The need for increased production is due to the huge population growth, which is expected to grow at the rate of 2.5% per year. It is stated that nearly all foodstuffs are finally got from the combined efforts of many different bioscientists. The U.S. has increased wheat production by 10% despite the fact that fewer acres are planted today than 10 years ago and the increased productivity of meat can be found in the growing of broiler chickens in the U.S.

The article focuses on a research work which is finding new methods of destroying the disease-producing potential of viruses and other substances in milk and food. The research is being undertaken by a group of scientists at the Public Health Service's Robert A. Taft Sanitory Engineering Center in Cincinnati. One of the main studies of the research look upon the use of heat to destroy typical viruses that may produce disease in humans and animals. A second study focuses on the use of irradiation to inactivate viruses in food products.

This article presents information related to periodicals related to infections and zoology. "Arbeitsmedizin, Sozialniedizin, Arbeitshygiene," is devoted to a series of papers on occupational mycotic infections. Sonck writes on Medical and Veterinary personnel, Forck on the Food Industries, Brehm on Agriculture, Fabry on Mining etc. "American Zoologist," has twelve papers published in it which have admirably up to date and well documented summaries of the present state of knowledge of many aspects of the comparative morphology and physiology of the vertebrate integument.
