plants and too early in the case of others in the same row. However, 

 as often happens in such cases, the difference was practically offset by 

 the yields of the second picking, which favored single-stalk culture by 

 15 per cent. There was practically no real difference in total yield, 

 though the old system had a very slight advantage. This was con- 

 trary to what was to be expected, in spite of the poor stand, as counts 

 of immature bolls made on August 14 indicated an increase for single- 

 stalk culture of 15 to 20 per cent. 



BOSSIER PARISH. 



Two experiments were conducted in Bossier Parish, both in the 

 immediate vicinity of Benton. One of these was on the farm of Mr. 

 E. S. Burt, parish agent, and was conducted by Essie Jackson, a 

 tenant; the other was on the farm of Mr. W. B. Wilbourn. 



The Jackson experiment. — Cotton of the Brown variety was planted 

 April 7 on low beds 4 feet apart. The soil, a sandy loam, was in good 

 condition and a full stand was obtained. Wet weather prevailed 

 during April, followed by dry weather during May, this being unfa- 

 vorable to good growth. 



The old-method rows were thinned on May 17, the plants, which 

 were 3 to 4 inches high with 4 to 5 leaves, being spaced 18 to 24 

 inches apart. The single-stalk rows were not thinned until June 9, 

 when the plants, being 10 to 14 inches high with 6 to 10 leaves, were 

 spaced about 8 inches apart. 



There were 26 rows in the experiment, and the two systems of culture 

 were compared in alternate rows. Two pickings were made. The 

 yields of each row for each picking and the total yields are reported 

 in Table VII.
