Table IX shows that in 6 out of 10 instances greater yields were 
obtained from single-stalk rows. In two instances the yields were 
identical, while in two other instances the old-method yield exceeded 
the single-stalk yield by 1 pound per row. The total yield of the 10 
rows favored single-stalk culture by 9.8 per cent. 
The Mercer experiment — While Mr. William Mercer, of Gilliam, 
cooperated in this work on the same basis as other farmers, he was 
left much alone in the conduct of his experiment. It was imprac- 
ticable to visit his field at thinning time, and consequently he 
thinned his cotton according to his interpretation of the general 
instructions offered. At all times, however, he cooperated with 
Mr. A. J. Scott, county agent. No report of how he planted his 
cotton or the time and method of thinning is available.. The only 
data available are given in Table X.
