EXPERIMENTS WITH SINGLE-STALK COTTON CULTURE. 
11 
The Webb experiment. — Mr. K. C. Webb, of Delta Point, planted 
Money Maker cotton on sandy soil on April 20 at the rate of three pecks 
per acre. The stand secured was poor generally, there being also a 
number of skips in each row. Owing to nonuniformity in germina- 
tion, there were, moreover, plants of various sizes in the single-stalk 
rows at thinning time. The smaller plants were still too young to 
have had their vegetative branches completely suppressed, while the 
larger plants had reached the stage where their fruiting branches 
were being suppressed. Since it was necessary to leave plants of all 
sizes in the row in order to have the spacing as uniform as possible, 
some allowances should be made in considering the results of the 
experiment. 
There were 30 rows in the experiment and the two systems of cul- 
ture were compared in alternate rows. The old-method rows were 
thinned on May 20, when the plants were 4 to 5 inches high and had 
3 to 4 leaves. The single-stalk rows were thinned on June 6, when the 
plants were 6 to 12 inches high and had 6 to 10 leaves. The plants 
in the old-method rows were spaced 18 to 24 inches apart, while the 
single-stalk plants were spaced at about 8 inches wherever the stand 
permitted such close spacing. 
Two pickings were made, the yields from each row for each picking 
being as shown in Table VI.

Table VI shows a difference of 19 per cent in favor of the old system 
of culture at the first picking. The lower yield of the single-stalk 
rows at this picking doubtless resulted, as already explained, 
from the fact that the thinning was done too late in the case of some
