Wealthy landlords were major producers, and the railways had notbeen introduced. Similar conditions existed in Argentina and Australia in the latter halfof the 1th century, but failed to produce any new grain-handling methods. Canada, be- cause of increased production of wheat, evolved its grading system with legislation in 1 for grain-grading and handling. 2.1 Beginning of the United States-Grading System As the grain elds of the . . Midwest opened up, surplus production was moved by river, rail, or wagon to Chicago and Milwaukee for onward movement to Canada or the eastern seaboard of the . . and later to Europe.

Club wheat: clean, 6 lb per Winchester bushel ( cylinder with diameter of 1.5 in. and depth of 8.0 in.)

The merchants paid fee to have their grain graded, andthis applied to grain coming into the Chicago market from other markets and also grain moving to markets outside of Chicago. 2.2 Origin of the Canadian-Grading System Wheat production in Ontario increased from 8,0 to 1.1 Mt annually from 1 to 1 (Irvine, . Most of the increase was in winter wheat and was due to many factors,such as an advancing frontier, large inow of immigrants to work the land and become producers, high prices, and good markets.
