 As already stated, the corn was of four varieties. These 

 varieties were as follows : Eureka, a large dent corn, seed 

 obtained from Koss Bros. ; Boston Market Ensilage, a large 

 dent variety, seed obtained from Joseph Breck & Sons ; 

 TA'aming Field, a moderately large dent variety, seed obtained 

 from Gregory ; Rural Thoroughbred, a large and late white 

 flint variety, seed obtained from Landreth. All varieties 

 were planted June (3. The field was given good care 

 throughout the season, growth was normal and healthy, 

 unaffected by accidental conditions which influenced results, 

 though all varieties were somewhat broken down by a storm

 tember 13 and 14, and weighed within twenty-four bom's. 

 The average for the several fertilizers was as follows : —

The only feature of the results to which especial attention 

 is called is the comparatively large yields obta,ined on the 

 muriate and nitrate, and the good yields on the compara-
