the growing season of 1922. This and all subsequent work was 
carried on under as nearly uniform soil and cultural conditions as 
could be obtained and is believed to be particularly free from vari- 
ation in these respects. 
EXPERIMENTS IN J 922 
Seed of seven varieties of peanuts — Jumbo, Virginia Bunch, Vir- 
ginia Runner, African, Valencia, Spanish, and Improved Spanish — 
grown at Florence, S. C, in 1921, was shipped to Washington, D. C, 
in November, immediately after picking, and placed in a wire-cage 
storage room at the Arlington Experiment Farm, near Rosslyn, Va. 
This storage was well ventilated and kept at temperatures between 
60° and 70° F. About February 1, 1922, the seed was removed to 
the building at 220 Fourteenth Street SW., Washington, D. C, where 
it was stored in large galvanized cans. There was sufficient seed for 
the various shellings, and all the seed had the same treatment up to 
the time of shelling.

On February 6 and 7, 1922, sufficient seed of each variety for the 
planting of two 90-foot rows was shelled. The shelling was done by 
hand, and only uninjured and reasonably perfect peanuts were 
retained. No effort was made, however, to select especially large- 
sized peanuts. All shelled lots were stored in the same caus as the 
remaining unshelled lots ; similarly, other lots were shelled on March 
6 and April 3, and the final lots on May 15 and 16, just before the 
time of planting. 
The seed was shipped by express to Florence, S. C, and two 90- 
foot rows of each lot were planted. All the peanuts were spaced 6
