The superiority of chemicals over prepared goods is again 

 demonstrated in these trials. The composition of the fertilizers 

 giving best three yields is as follows : 



Towle. Whittemore. McDaniel. 



Phosphoric acid % 10.8 11.6 4.0 



Potash % 11.0 7.1 24.1 



Nitrogen % 2.1 2.3 0.2 



plot 6. 



This plot, as before mentioned, had such fertilizers as each 

 experimenter chose to apply. 



Gov. Goodell applied 32^2 pounds of Soluble Pacific 

 Guano ; unfortunately this was applied in the hill while all 

 other fertilizers were broadcasted, comparison under this con- 

 dition is impossible. 



Mr. McDaniel used 4 bushels of hen manure on this plot; 

 Mr. Gerrish 2 bushels of hen manure; Dr. Towle applied 28 lbs. 

 of Quinnipiac fertilizer ; Mr. Baker used 28 lbs. of Bradley's 

 XL; Mr. Wood use 21J/2 pounds of ground bone and ^ bushel 

 of ashes, Mr. Whittemore applied 28 pounds of Stockbridge 

 Potato Manure. 



COMPARISON OF COST AND PRODUCT. 

 Husked Corn. 



Average yield with no fertilizer 



Average yield with Manure 



Average yield with 3 Best Chemicals was 



Average yield with Ashes 



Average yield with Prepared fertilizers 



Fodder. 



Average of "nothing" plots 



Average of Manured plots 



Average of plots with Chemicals 



Average of plot with Ashes 



Average ot ploi with Prepared fertilizer 



If we call the corn worth 25 cents per husked bushel and 

 the fodder worth $5.00 per ton, we can find the value of the in- 

 creased product, and, calling the manure worth $15.00 per acre, 

 and all other plots $10.00 per acre, which is what the fertilizers 

 would cost in any market, we can draw up the following ex- 

 hibit of cost and income :
