The vines in all plats looked healthy throughout the season ; 

 they began to turn yellow first on Plat 2. The potatoes on 

 all plats were harvested August 11 and 12, when the leaves 

 were dead but the stems still green. They were smooth 

 and free from seal). The different plats yielded the follow- 

 ing weights of large, marketable potatoes and of small 

 potatoes : — 



This experiment will be continued during the coming 

 season with the same crops and with the same mixtures of 

 fertilizing ingredients, making such alterations as the ex- 

 perience of the past season suggests. The results of the 

 first year are above presented without any further comment. 



A critical discussion of the results is deferred to a later 

 period in our investigation, when the experience of several 

 years will furnish a safer basis for deduction.
