"The experiment this year shows that not only can sweet potatoes 

 be raised by chemical manures alone, but that the increased yield was 

 sufficient to pay a considerable profit. 



"The average net gain for 1892-1893 from the use of chemicals is 

 I22.65, while that from the horse manure has been hardly sufficient to 

 pay the cost of the manure."

"Potash alone develops more sugar per acre than any other single 

 material. ...

 the element ^yhicb influenced sugar production in sorghum roost 

 favorably." '
