INTRODUCTORY 



In studying the pages which follow, one cannot be anything but 

 impressed by the remarkable story of agricultural progress which is 

 written in them. It is the story of Iowa's greatest industry and of 

 Iowa's greatest source of wealth. 



Few of our early pioneers, whose works were reflected in the 

 First Volume of this yearbook, would have believed that such 

 things were possible as are recorded in this, the Twenty-first Vol- 

 ume. The table of Iowa's Source of Wealth, which shows the 

 state's 1920 agricultural products and live stock totaling a value of 

 $1,175,504,318, is mute testimony to the wonderful strides which 

 have been made by the farming peoples of the commonwealth. 



The sections devoted to the Iowa State Fair, Farm Bureau Feder- 

 ation, Corn Belt Meat Producers' Association, Weather and Crop 

 Service, and like institutions, record an equally graphic picture of 

 rapid and wholesome advancement. 



True lowans should know the story which is told in the pages 

 that follow. And Iowa farmers may well be proud of the part they 

 have played in the making of the story.
