The cobs yield an abundant supply of potash. Large mills 

 can furnish a big product of corn-cob potash. A mill shell- 

 ing 500 bushels an hour turns out 7000 pounds of cobs an 

 hour, or equal to 70,000 pounds per working day. 1 The cobs 

 are used for fuel in the mills, and the refuse ashes are col- 

 lected for the extraction of the potash, 1000 pounds of cobs 

 yielding 7.62 pounds of potassium carbonate, or in a factory 

 of the above capacity 535 pounds per day. 



It seems strange that during the century which has elapsed 

 since our birth as a nation no adequate conception has been 

 reached as to the true value of the commonest product of our 

 soil — our native Indian corn.
