Average of nothing plots ; hard corn, 25.7 bushels ; soft corn, 0.8 

 bushels ; stover, 2930 pounds. 



The field selected for this experiment adjoined that used last year. 

 It lies just south of Forest river, near Salem harbor and has a consid- 

 erable slope towards the river, i. e., to the north. The soil is a fine 

 gravelly loam for a long time in grass without manure. 



The upper ends of the plots which run up and down the slope 

 varied in natural fertility so much that we threw them out, taking 

 the lower five-sixths of each plot only into account. The vai'iety 

 planted was eight-rowed yellow flint corn. The field was planted 

 May 23d ; stooked, Oct. 4th and 5th and husked Oct. 31st. It was 

 well cared for throughout the season. In Jul}', plot No. 10 appeared 

 to be the best, while No. 13 was nearly equal to it. In August the 

 position of these plots was reversed. Throughout the season Nos. 

 9, 7, 6, 5, and 2 were nearly even.

No important falling off in the condition of the plots receiving the 

 fertilizers with the advance of the season is shown. The effect was 

 early shown and well maintained in most cases.
