The history of the grain trade was described. Since ancient times wheat had been dominant as the source of man's daily bread. In the middle of the 19th century trade in other grains increased with demand for feedstuffs in the production of meat and eggs, and with the use of cereals as raw material in numerous industries. Trade increased sharply with rising demand and with increasing production in new countries. World production reached its peak in the period 1925-30. This period however laid the basis for the agricultural crisis. After 1925 many European countries protected their own wheat production. The influence was described of methods of transport, technical improvements in agriculture and rising incomes of the consumers.

The motion pictures produced by the United States Department of Agriculture are informational and instructional in type. They are designed to aid in disseminating information on the needs for agricultural products, their production, distribution, and utilization. They demonstrate improved methods in agriculture and home economics, stress the need for conservation of soil and other resources, explain the farm credit system, forestry, land use, marketing, and kindred subjects, and help to increase the effectiveness of cooperative extension work.
