The Cereal Rusts, Volume II: Diseases, Distribution, Epidemiology, and Control is a compendium of papers that aims to control cereal rusts through principles about the nature of the disease, as well as learned strategies toward its control. These papers deal with the major cereal rust diseases such as wheat and rye stem rust, wheat leaf rust, stripe rust, oat stem rust, barley leaf rust. Control of these types of rust diseases include cultural methods, barberry eradication, crop resistance, fungicides, and ecological controls. One paper notes that cultivars, a plant variety developed through selective breeding, should be used. The key to its development with long-lasting resistance is diversity, namely, genetic diversity in resistance types, and diversity in its strategic development, including a combination of race-specific with non-race specific resistance. For example, Parlevliet has pointed out that in natural ecosystems, race-specific resistance can protect the host plant by rendering the pathogen population less aggressive. One paper also examines the use of chemicals for rust disease control in the United States. This compendium is ideally suited for the cytologists, physiologists, biochemists, geneticists, epidemiologists, taxonomists, and cereal plant pathologists.

The purpose of this handbook is to provide members of the Forest Service with conversion factors and forest measurements that are more or less frequently encountered in forest literature. These are expressed in tabular form where it appears most advantageous to do so; in the other cases a series of alignment charts have been prepared, which permit the direct determination of values in multiple form. There are included also certain other tables giving data more or less commonly used in forest calculations.
