SAMPSON COUNTY. 



Three experiments were conducted in Sampson County, all in the 

 immediate vicinity of Ingold, on sandy-loam soil. The writer directed 

 the thinning of the single-stalk rows in the latter part of June, when 

 it was found that had thinning been done a week or 10 days earlier 

 it would have been far more favorable. Still, fairly satisfactory 

 comparisons of the new with the old system of culture were possible. 



The Sloan experiment. — Mr. H. D. Sloan planted Prolific cotton, 

 of the King type, on April 20, and a good stand was secured in spite 

 of unfavorable weather. The old-method rows were thinned on May 

 25 and the single-stalk rows not until June 28. The plants in the 

 former rows were 3 to 4 inches high with 3 to 5 leaves, and they were 

 spaced 18 inches apart. In the latter rows the plants were 8 to 10 

 inches high with 6 to 10 leaves, and they were spaced 6 to 8 inches 

 apart. 



There were 30 rows in the experiment, 20 in which the systems of 

 culture were compared in alternate rows and 10 in which com- 

 parison was made in adjoining blocks of 5 rows each. Only one 

 picking was made. The yields reported by Mr. Sloan are given in 

 Table XV.
