The flowers opening each day were counted, and 

 each morning all the sheddings were picked up and 

 counted from two rows of each type. The number of 

 plants were: Ishan, 769; Allen's Improved, 849; Nyasa- 

 land, 737; and Durango, 772. 



The buds and bolls which had been bored by the boll 

 worm were separated from the others and counted. 



All these types, with the exception of Nyasaland, were 

 planted on July 15; Nyasaland, which arrived late, was 

 planted on July 28. 



The rainfall in August this particular year was very 

 heavy in comparison with other years, between 10 and 

 ii in. being recorded; September was lower than the 

 average with 8J in. ; the rain ceased on October 19 after 

 nearly 5 in. had been recorded for the month. No more 

 rain fell until February 26 of this year. 



The plants grew exceedingly well, not too large, but 

 just a good average size. 



In the case of the exotic types, flowering commenced 

 eight weeks after planting, and in four weeks from that 

 time the maximum number of flowers were opening per 

 day. This maximum was maintained for about a week, 

 then flowering began to fall off, and in from eight to nine 

 weeks from the commencement of flowering it had fallen 

 to a minimum. In four months from the time of planting 

 the first flowering period was completed. After this new 

 growth rapidly took place, and in two more weeks a 

 second flowering period had commenced. This last 

 flowering period only lasted from four to five weeks, and 

 the number of flowers opening per day did not rise so 

 high as in the first flowering period. 



With Ishan, a native variety, the flowering period was 

 a long drawn out one, the first flowering period only 

 ending when the exotics were finishing their second 

 period. The flowering of Ishan commenced ten and a 

 half weeks after planting; the maximum flowering period 

 was reached five weeks later, and this flowering period 

 was finished seven weeks later. The flowering period of 

 this type, therefore, lasts twelve weeks. 



The shedding of flower-buds commenced before any 

 flowers opened, and the shedding of small bolls com-
