The Sweet Potato 



way was equal if not superior to corn-starch in cooking 

 and it was found that an excellent quality of library 

 paste having powerful adhesive power could be manu- 

 factured from it. 



A theoretical yield of approximately ten pounds of 

 pure starch to each bushel of sweet potatoes has been 

 secured in the laboratory with scientific methods. The 

 following table gives the analyses of fourteen varieties 

 and shows an average of 18 per cent starch, although 

 it will be noted the starch-content varies considerably 

 with different varieties. The analyses were made by 

 Keitt of the South Carolina Station who calls attention 

 to the fact that " one indication which appears worthy 

 of note is that the water content as a rule varies from

 Water-Content, Starch-Content, and Yield in Pounds 

 PER Acre. 



Note — The bushel per acre yield being calculated from small 

 areas can be taken only as comparative.
