Florida Agricultural Experiment Station samples the first group appeared as early as the sixth day and in others it was as late as the 12th day. No adjustment has been made for this discrepancy but all seeds in early emerging groups have been segregated in the first class of frequency distributions by setting the upper limit of that class at 17 days after planting where a minimum of daily emergence occurred. The first class has an interval of 11 days because the time re- quired for germination was not constant. Ideally its interval is zero and actually it is composed almost wholly of seeds which required no rest period. The upper limit of the first class might have been set at 13 or 25 days with no appreciable variation of class frequencies. 8o 0 5 20 0 r& 0 1 0 0 5 70 105 14o 175 210 245 Days after harvest when planted Fig. 2.-Progress of after-ripening measured by time from planting to emergence in Spanish peanuts, Strain No. 1, with different conditions of storage: (a) Shed storage at mean temperature of 20-25* C., continu- ously after harvest; (b) Shed storage 48 hours after harvest, then at 3 C.; (c) Shed storage ten days after harvest, then at 3 C. It was not feasible to grow many plants to maturity from seeds germinating in rest period tests and F1 and F2 seeds were not easily obtained in large numbers. Consequently, most of the tests were run in later generations. Records on pure strains
