Excerpts from the report Preface: This report is based on one of a series of studies of the operation of Federal milk marketing programs in different fluid milk markets of the country. Previous reports in the series dealt with milk marketing in Philadelphia, St. Louis, Duluth-Superior, and Minneapolis-St. Paul. Each report has emphasized some aspect of milk marketing that is characteristic of the respective market. The present report on the Kansas City, Mo., milk market covers the period from early 1930 to 1936. During those years the milk industry of Kansas City and the Federal Government, independently or together, were attempting to stabilize the milk-marketing process. The period comprised the formative years for Federal regulation of milk marketing. The marketing plans which were tried in Kansas City during the 1930 to 1936 period used various combinations of use classification, auditing, pooling, base-rating, and other fundamental and accessory devices employed in today's markets. A study of the experience in this market contributes to a better understanding of milk marketing devices and practices.
