gained through increased yield of seed cotton. This condition does 
not exist, however, as shown by the results of determinations made in 
connection with the present experiments and those previously 
reported. 
LINT PERCENTAGES. 
Table XXII gives the per cent of lint as determined in samples of 
seed cotton sent in by five farmers from their respective experiments. 
Reference to Table I, page 4, will show the locations of these 
farmers, which fairly represent the general distribution of the experi- 
ments. One is in south-central Louisiana, one in northeastern 
Louisiana, one in southwestern Arkansas near the Arkansas- 
Louisiana line, and two are in North Carolina. The varieties used in 
these experiments were, respectively, Half-and-Half, Sugar Loaf, 
Triumph, Prolific (probably King), and Cleveland Big Boll.

Table XXII shows practically no difference in the average percent- 
age of lint obtained under the different systems of culture. The 
difference is remarkably small in view of the great differences in per- 
centage among the individual samples from some of the experiments. 
The greatest difference in average percentage of lint is 1.2, and this 
favors single-stalk culture. In three other instances the differences 
range from 0.6 to 0.8 per cent in favor of the old method. In the 
remaining instance the average percentages are identical. 
RELATIVE abundance of lint. 
The percentage of lint in itself is no more a safe basis for compar- 
ing the effect of different cultural methods than it is for judging the 
relative value of varieties. 1 The percentage of lint would vary
