A larger amount of fertilizer was added during the last few 

 years of the experiment in order to insure the maximum de- 

 velopment of the crop. The yield of corn when planted on the 

 same land for several successive years is likely to decrease, 

 and it was thought that the additional amount of plant food 

 applied would in a measure check this probable shrinkage. 



The chemicals were mixed, sown broadcast and harrowed in 

 just before the corn was planted. While the application of 

 commercial fertilizer was liberal, it is believed that larger 

 yields might have been secured, in some cases at least, if more 

 organic matter had been added to the soil either through the 

 medium of barnyard manure or as a cover crop to be ploughed 

 under in the spring. 



The Pride of the ISTorth and Eureka corn grown in 1904 

 were not planted on the twentieth-acre plots, but were grown 

 on one-half acre plots in an adjoining field. It was fertilized 

 with cow manure at the rate of six cords to the acre and the 

 land well fitted. In this case the rows ran north and south 

 and the corn was sown in drills and thinned to one plant to the 

 foot at the time of hoeing. 



The corn grown on one-twentieth acre plots was planted in 

 hills 3I/2 by 3I/2 feet, and thinned to four plants at the time of 

 hoeing. It was seeded May 20-25 and harvested September 15, 

 which is about as late as it is advisable to allow corn to stand 

 and be safe from frosts. 



Description of Varieties. 



TiuitcheU's. — A small growing yellow flint bred in Maine. 

 On account of its early maturing qualities (with us in the 

 vicinity of August 20) it may be grown as far north as corn 

 culture can be considered profitable. It has a short stalk of 

 small diameter and a good-sized ear, in some cases two ears 

 being noted on each stalk. It cannot be considered well suited 

 for forage or silage where larger varieties will mature. 



Sanford White. — A white flint corn, quite like Longfellow 

 in general appearance, size of plant and time of ripening. 



Longfellow. — An old established yellow flint variety ex- 

 tensively grown in Massachusetts. It is one of the best of the 

 yellow flint varieties.
