1. Why grow potatoes ? — The potato is one of the most im- 

 portant food crops of the United States. It is grown in all parts 

 of the country and is consumed in large amounts by practically 

 all classes of people. Good local markets for this crop may be 

 found in almost every county. As a business proposition the cul- 

 ture of the potato deserves careful consideration. The crop is not 

 difficult to grow, and it offers special inducements to those who 

 understand and apply the principles relating to its culture. 



It is estimated that the average annual world crop of potatoes 

 is about 5,000,000,000 bushels, 90% of which is grown in Europe.
