made by Mr. E. S. Burt, agent for Bossier Parish; Mr. A. J. Scott, 
agent for Caddo Parish; and the writer. Then there were 40 to 50 
per cent more bolls on the single-stalk rows and it was confidently 
expected by all present that the yields would vary in about the same 
proportion, favoring single-stalk culture. It is believed that much of 
the cotton on the single-stalk rows had fallen from the bolls before 
picking time, for the crop was not picked until October 26, which 
was unusually late.

CADDO PARISH. 
Two experiments were conducted in Caddo Parish, one on the 
farm of Mr. C. C. Herndon, near Shreveport, and the other on the 
farm of Mr. William Mercer, at Gilliam, about 20 miles northwest 
from Shreveport. 
While early seasonal conditions in this part of the State were 
more favorable to the normal growth of the crop than in most other 
sections, they were not ideal, in that some drought obtained during 
April and May. 
The Herndon experiment. — This experiment was the only one of 
the series in which single-stalk culture was compared with the usual 
method on an acre basis. The single-stalk acre was located in a 
rather low corner of a field of several acres, and it maintained only 
a fair stand. Moreover, there were several skips in each row. The 
field was planted rather late in April, and dry weather prevented uni- 
form germination. 
There was a difference of only nine days in the time of thinning 
the two plats in this experiment. The old-method rows were thinned 
on June 4, when the plants were 3 to 4 inches high and had 2 to 4 
leaves, while the single-stalk rows were thinned on June 13, when 
the plants were 6 to 8 inches high and had 5 to 8 leaves. The 
plants in the former rows were spaced 18 to 24 inches apart and those 
in the latter 6 to 8 inches.
