This book describes briefly some of the methods frequently employed for the propagation of deciduous fruit trees as well as a number of the trees and shrubs used for the adornment of home grounds. Practical details concerning the care and handling of tree seeds, the culture of seedlings, the successive steps in the handling of cuttings, layers, grafts, and buds in order to succeed in these operations, as well as the methods of propagation most suitable for the several kinds of woody plants, are presented.

This book, specially prepared for soil scientists and engineers, offers comprehensive coverage of basic soil concepts, systematics, mapping and examination procedures for soils. Specific National Standards and Procedures for classification of soils, design and name of map units, conventions for nomenclature, and location of special soil features are outlined. It provides standards for uniform and correct use of words and ideas and does much to standardize terms and procedures. Soil and landscape, character of soil maps and reports, field work, plotting, description of soils, parent materials, soil color, texture, structure, consistence, reaction, special formations, organic matter, erosion, vegetation, land use, soil classification, samples, correlation and inspection, report, reconnaissance are included. The Soil Survey Manual provides in a single volume the major principles and practices needed for making and using soil surveys and for assembling and using data related to them. The Manual is intended primarily for use by soil scientists engaged in the classification and mapping of soils and in the interpretation of soil surveys. It is oriented to the needs of those actively engaged in preparing soil surveys for publication. The Manual is universally useful and is the primary reference on principles and technical detail for local, State and Federal contributions to authorized soil surveys. Soil scientists concerned with soil surveys in other countries have used it as well. Teachers have used it both as a text and as a reference for students.

Cheese is a highly nutritious and palatable food. It is of value in the diet because it contains in concentrated form almost all the protein and usually most of the fat, as well as essential minerals, vitamins, and other nutrients, of milk. Cheese is made wherever animals are milked and produce more milk than the people use in fluid form. Most cheese is made from cow's milk, simply because cows are milked more generally throughout the world than other animals. Smaller quantities are made from the milk of goats and ewes. Cheese is also made in some countries from the milk of other animals, such as camels, asses, mares, buffaloes, and reindeer. People all over the world like and eat cheese. People in the United States are no exception. Although we do not eat nearly so much cheese per capita in the United States as do people in some countries, we eat nearly twice as much now as 20 years ago, or about 14 pounds (all kinds) per capita per year. This increased consumption is the result, at least in part, of improvements made in recent years in the quality and uniformity of many kinds of cheese. This publication was prepared to answer the questions of many people who ask for general information on the characteristics of cheeses and methods of production. Descriptions of the chesses were derived from many sources. Information came from a study of the literature and from cheese manufacturers and research workers. Although every effort was made to get complete and accurate information, often only fragmentary information was obtained.
