varieties themselves there is the broad difference of 

 $15.72 by which Cook 307-6 exceeded that of Modella. 

 The three largest yielding varieties named in order 

 were Cook 307-6, Wood and Covington-Toole. 



Mr. W. J. Bridges: This experiment is located on a 

 dark sandy soil in Notasulga; the surface of the plots 

 is almost level, with the exception of a shallow sag that 

 rims across all of the plots. The field has been in cul- 

 tivation many years. 



The total value of the lint and seed of the Cook 

 (check) was $43.29 per acre, while the average of the 

 wilt-resistant varieties was $53.11, making an average 

 difference of $9.82 in favor of the latter varieties. The 

 four largest yielding varieties, named in the order of 

 their value, were Tri-Cook, Covington-Toole, Wood 

 and Dillon. 



Mr. T. J. Biirk: This experiment is located on badly 

 infected land in Tuskegee; the surface is almost level; 

 the soil is a fine sand, or silt, and has been in cultiva- 

 tion for a half century or more; its fertility is above 

 that of the average farm land. 



The total value of seed and lint per acre shows a 

 range in value from $14.74 on the lowest check to 

 $55.96 on Dixie the highest wilt-resistent variety in this 

 experiment. The second check was on land not badly 

 infected with wilt- The average gain of all the wilt- 

 resistant varieties over the average value of the checks 

 is $18.90 per acre. 



Mr. Jim Whatley: This experiment is located about 

 a mile and a half from Auburn on light sandy soil 

 with a yellow subsoil. During the past ten years cot- 

 ton has been grown on this piece of land alternately 

 ^^ith corn and cowpeas and with corn and grain; the 

 hmd has been fertilized liberally with commercial fer- 

 tilizers, lot manure and leguminous crops. 



The total value of lint and seed per acre from the 

 first picking September 4th (the weights of the late 

 pickings were lost) was $21.13 for Covington-Toole, 

 $19.32 for Tri-Cook and an average of $14.94 for the 

 Cook (checks). Covington-Toole gained $6.19 and 

 Tri-Cook $5.13 per acre over the average of the checks. 



Mr. W. W. Thompson: This experiment is located 

 at Liverpool, Macon County; the soil is a fine sand 

 with a fine yellow sandy subsoil and has been cultivat-
