FITTING, PLANTING, CULTIVATION, ETC. 
At Geneva.—The plat of land used was adjacent. to that used 
for the experiment in 1903 and of the same kind of soil; namely, 
a heavy clay loam with some gravel in it. In 1903 it grew corn. 
In the fall well rotted stable manure was applied, by means of a 
manure spreader, at the rate of twenty-four loads per acre and 
plowed under. The following spring the land was plowed again, 
on May 18. There having been plenty of rain the soil was 
moist, but in spite of thorough harrowing it was left lumpy and 
in poor condition for planting. 
The rows were marked out! three feet apart. Immediately be- 
fore planting the furrows were opened with a plow. Fertilizer 
at the.rate of 200 pounds’ per acre (four pounds to each row) | 
was scattered in the furrows by hand. Planting was done May 
’For details of the experiments in 1903 see Bulletin 241 of this Station.
