None of the other culms were followed so far as No. 1. 
A glance at fig. 1 shows that after a height of about 4*5 
metres had been reached (on June 26)the growth continued 
fairly steady, with perhaps some signs of a gradual falling 
off towards the end of the period of observation. Consider ¬ 
able irregularities, however, occur from day to day, and the 
agreement which these variations show with the variations 
in the amount of rainfall is very striking. The greatest 
difference between the amounts of growth on two consecu¬ 
tive days was 148 mm., between 312 mm. on July 29 and 
460 mm. on July 30—a difference which amounts to 32 per 
cent, of the greater growth. The rainfall on these two days 
was 4*5 and 35*9 mm. respectively. 
The agreement between growth and rainfall is equally 
marked whether the daily or the three-dav curve is taken 
into account. A drought of one or two days is regularly
