The purpose of this study is to collect, analyze, and interpret physical and pricing data pertaining to the elemental market structure for grain sorghums in Texas. For comparative purposes, a criterion is established in Chapter IV to evaluate the data obtained. The objective is to deter mine whether the physical and pricing aspects of the Texas grain sorghum market structure conforms to theoretical structural patterns. If there are deviations from the theoretical pattern, explanations will be sought. No attempt will be made in Chapter II, "Physical Structure", and Chapter III, "Pricing Structure", to evaluate the data given, but only to report the functioning characteristics of these aspects.
