early variety of Dent corn. The arrangement was perfect and the 

 field well adapted for the purpose ; but germination was uneven and 

 squirrels did considerable damage. There were many vacant hills, 

 especially in plots 1 and 2. We, however, report the actual yield. 

 The date of planting was June 9th ; the crop was stooked Sept. 27th 

 and husked Oct. 11th. Plot No. 15 was benefited by manure used 

 on the land adjoining it.

In this experiment, too, nitrate of soda excels the adjacent nothings 

 more in mid-season than at the close, indicating either that it had 

 been washed away or entirely used up before the end of the season. 

 We must be cautious about drawing deductions here, however, 

 because the plants measured were not the same each time. 



ANALTSIS OF MANURE USED. 



Moisture at 100° C, 76.37 per cent. 



Potassium oxide, .370 " 



Phosphoric acid, .368 " 



Nitrogen, .420 " 



Insoluble matter, 7.835 " 



This manure weighed 43 pounds to the cubic foot, 1376 pounds 

 were used on the plot. This amount furnishes, per acre : nitrogen, 

 115.6 pounds; phosphoric acid, 101.3 pounds, and potash, 101.8 

 pounds. Yet on this poor land it increased the crop only about 

 fourteen bushels per acre. The poorness of this result was doubtless 

 largely due to the lateness of planting and the many vacancies in the 

 field.
