Table II. gives the averages and the maximum and minimum for 

 the same periods (p. 71). 



Table III. gives the same information with regard to the 38 stocks 

 common to both the trials of 1911 and 1913 (p. 72). 



Table IV. shows the sunshine and rain records for the period of 

 growth during the year 1913 (p. 74). 



Table V. is a comparative table of the averages of the 38 stocks 

 common to both trials, as well as the total amount of rain and 

 sunshine during the different stages of growth (p. 75). 



As previously noted, the acceleration of germination during the 

 three sowings is marked ; the average periods compare as follows : —

One curious and unexpected fact is at once noticeable : namely, 

 that although there was an average acceleration of about nine days in 

 germination, not a single stock fell into the 80-90-day Pea class of 

 1911, in spite of the fact that similar stocks were tried. This is true 

 of the whole 217 stocks. 



A slight acceleration of germination occurs in the second sowing, 

 of about two days. 



The third sowing remains constant. 



This thus appears to prove that the germination and its accelera- 

 tion up to a certain limit depend solely on the increasing warmth of 

 the soil under normal climatic conditions. 



The interval for the production of the first flower again shows 

 marked fluctuations ; the comparison of average results is as follows : —

It will be seen that in the last two classes the results for the two 

 years are scarcely comparable, and on examination of the averages 

 for the ready-to-pick period the same fluctuations are just as marked, 

 namely : —
