Again making the same comparisons as in the previous analysis, 

 it will be found that the interval between " above ground " and " first 

 flower " was longer in the third sowing than in the second : — 

 in the case of 91-ioo-day Peas 9 times, or 12J per cent, 

 loi-iio ,, 9 ,, 29 



over III „ 2 ,, ,, 100 



that the interval between " first flower " and " ready to pick" was 

 longer in the second sowing than in either the first or third sowing : — 

 in the case of 91-ioo-day Peas 9 times, or 12J per cent, 

 loi-iio „ „ 6 „ 19J 



over III ,, ,, 2 ,, ,, 100 

 and that the interval between " first flower " and " ready to pick " 

 was longer in the third sowing than either the first or second sowing : — 

 in the case of 90-100 day Peas 58 times, or 81 per cent, 

 loi-iio „ „ 14 „ „ 45 

 over III „ „ o „ o 



These percentages compare favourably with those of the previous 

 trials, except in the case of the interval between first flower " and 

 " ready to pick " in the third sowing as compared with that of the 

 first or second sowing. 



For the examination of the climatic influences Tables IIL, IV., 

 and V. have been calculated. The summary in the last five columns 

 of Table V. is interesting, showing as it does the similarity of the 

 abnormal conditions of the years 191 1 and 1913. The failure of the 

 third sowings in both cases may be justly attributed to the excess of 

 sunshine, and to the fact that Peas require more rain for their 

 cropping with certainty. 



In conclusion, it is evident, in order to obtain more certain and 

 clearer facts on the rate of growth and the development of crops, 

 repeated trials would have to be made. Whether it would be advisable, 

 and whether the results would repay the trouble, the author must 

 leave to the Society to decide. Undoubtedly the conclusion drawn from 

 the first trials is confirmed — namely, that it is obviously the period 

 of fructification which requires shortening in order to bring the late 

 Peas safely to fruit independently of the climatic conditions. It does 

 seem to point to a repetition at some future date, so that a normal 

 condition of climate may be examined in comparison with the three 

 periods of growth.
