Average of uothing plots; hard corn, 11.7 bushels; soft corn 4.3 

 bushels; stover, 2156 pounds. 



The field selected for this experiment was a higb-h ing piece of 

 laud just south of Forest river, near the place where it empties into 

 Salem harbor. It had a considerable slope towards the river, i. e., 

 towards the north. The soil was a fine gravelly loam, and proved to 

 vary considerably in natural fertility in different parts of the field. 

 The greater part had been in grass and unmanured for ten years, a 

 small portion had ))ceu cultivated within five years ; but had received 

 little manure. Since that time it had been iu grass unmanured. 



In this experiment, which in almost all respects was excellently 

 carried out, the fertilizer used on plots 6 to 10 inclusive was not 

 applied exactly acording to stakes. The growth of the crop showed 

 that it was put in general, one row too far to the east. It was, how- 

 ever, thought best to weigh the crop according to the plots as staked, 

 and to publish the results, although this accident, in a measure, 

 obscures the eiTect of the fertilizers. 



In July the following notes were made : Plot No 10 best as a 

 whole ; No 7, second ; No. 13, third ; No. 9, fourth ; No. 5, fifth. It 

 will thus be seen that potash appeared at this time most effectual 

 among the ingredients of the fertilizers used ; and the differences up 

 to this pomt were decided. Between the other plots and the nothings 

 the differences were much less noticeable. 



In August the barn-yard manure was showing better, Nos. 10 and 

 9 were still showing well while No. 5 had relatively fallen back.
