This gave us conclusive evidence that there was some connection between type of corn and the prevalence of the root disease, as well as a correlation between type and yield. It occurred to me that since the corn disease was threatening to be national in character, I decided to take the matter up with the United States Department of Agriculture. I had done some work before in co-operation with the Agricultural Department, with oats, clover and testing of corn stalks for making paper. The government complied with its co-operation, and Mr. Holbert became an employee of the Department and has been working on the problem ever since. A good deal of progress has been made. A lot more investigation remains to be done. It is our hope to discover immune strains within varieties. In the absence of immune strains, we are planting corn that shows free of infection on the germinator and putting this corn in new or clean ground. The disease clings to old stalks and on various weeds. Contrary to previous teaching we are now burning the stalks to keep the.

We do not know how long these diseases will remain in the soil, and we are asking the Government and the University of Illinois to make a num- ber of investigations along this line. Also, we should know what. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these i
