where it is more compact or clayey, which probably affected in a 

 slight degree unfavorably, one end of plots 11, 12, 13, 14 and 15. 

 The land was in pasture until about twenty years ago. Since that 

 time it had been alternately under the plough and in hay and had 

 been ploughed once in from three to five years. For the last eight 

 years it had been under high culture, being ploughed once in four 

 years with a good dressing of manure and chemicals for sweet corn, 

 and in hay the other three years with a yearly dressing of either 

 manure or chemicals. It had been top-dressed the preceding fall 

 and was in condition to bear a good crop without further manuring, 

 as will be seen by reference to the yield of the nothing plots. 



The experiment was admirably managed in every respect, not 

 being hand hoed at all, and yet being kept almost perfectly free from 

 weeds. The variety of corn was an eight-rowed, yellow flint. It 

 was planted May 16th and 17th, in hills 3 feet 4| inches apart each 

 way, and three stalks were left in each hill. It was stooked Sept. 

 25th, and husked Nov. 20th. 



Notwithstanding the high condition of the soil, the potash where- 

 ever used produced a very perceptible improvement from the first. 

 The nitrate of soda also showed itself, though to a less extent. Both 

 in July and in August when visited. No. 10 was the best plot in the 

 field. Next in order were 13, 9, 7, 6, and 5.

These figures afford no positive evidence of a comparative falling 

 off in the plots receiving fertilizer with the advance of the season, 

 except possibly in the case of plot 2, where nitrate of soda only was
