these plantings. During the period from July 13 to July 31, the date 
when flowering practically ceased, the May 5 planting produced the 
largest number of flowers relative to the number of plants, while the 
April 19 planting produced the smallest number. The total number of 
flowers counted during the entire season was nearly the same in each 
of the first three plantings, being, respectively, 2,606 for the April 19 
planting, 2,517 for the April 28 planting, and 2,620 for the May 5 
planting. On the two 50-foot rows of the May 12 planting 866 
flowers were counted. The small number of flowers produced on 
these rows was due to the very irregular stand of plants. 
TaBLE 9.—Numbers of flowers counted from 50-foot sections of rows of cotton grown 
in successive plantings at San Antonio during the period from June 26 to July

Most of the flowers produced after the middle of July were shed as | 
a result of adverse climatic conditions. The ability of late-planted 
cotton to continue flowering under severe conditions is to be noted, | 
however. This probably was connected with the continued produc- 
tion of internodes on the lower fruiting branches of the late-planted 
cotton, which occurred both at San Antonio and at Charleston. 
SHEDDING OF BOLLS IN EARLY AND LATE PLANTINGS 
As a result of dry weather considerable shedding of bolls occurred 
in the different plantings. In order to compare the extent of boll 
shedding in these plantings, the numbers of shed bolls were recorded. 
from the 50-foot sections of rows on which the flower counts were 
obtained. These counts do not represent the total number of bolls, |
