33.S91 c^rammes. Length of fibre ist test, 25.6 millimeters; 3cl test, 

 20 millimeters; 3d test, 23.2 millimeters; 4th test, 22.4 millimeters. 

 Average length, 22.8 millimeters. Diameter of fibre, 0.016 millime- 

 ters. This is an improvement over the two preceding. The twist of 

 the fibre is an average, but there was a good deal of waste in the boll. 



Number 4 was obtained from the same plat that No. 2 came from, 

 but was not blighted. Rupture: 29.151, 23.652, 21.061, 26.719 

 grammes. Average for two stands, 25. 145 grammes. Length of fibre, 

 17.6, 21.6, 21.6, 21.6 millimeters; average length, 20.6 millimeters; 

 diameter, 0.016 millimeters. The twist was medium. The resistance 

 to rupture was more uniform than the preceding, and the staple was a 

 better grade. 



Number 5 was another specimen of blighted cotton from the same 

 field in the plat fertilized with floats and cottonseed meal. The fibre 

 was quite imperfect in development, and the twist was inferior. Re- 

 sistance to rupture: 13.990, 5.620, 11.237, 13.000 grammes. Average

resistance, 10.962 grammes. Average length of fibre, 20.2 millimeters ; 

 diameter, 0.024 millimeters. 



Number 6 represents the variety Peerless. The stalk was large, well 

 developed, and loaded with fruit. The field in which the plant grew 

 was fertilized with compost, 200 pounds cottonseed meal, and 200 

 pounds acid phosphate, 1,000 pounds to the acre. The diameter of 

 fibre was 0.016 to 0.024 millimeters, the last measure predominating. 

 The twist was about an average and the length ranged from 18 milli- 

 meters to 20.8 millimeters. Average 18.5 millimeters. The resistance 

 to rupture: 23.142, 20.552, 28.044, 11-623 grammes. Average 20.840 

 grammes. This is a good grade of cotton, wnth even texture and uni- 

 form diameter. 



Number 7, or Welborn's Pet, was fertilized in the same manner that 

 was used with No. 6. The plant was large, well fruited, and apparently 

 healthy. Diameter of fibre, 0.016 to 0.034 millimeters. Length : 21 .6, 

 23.2, 21.2, 22.4 millimeters. Average 22.1 millimeters. Resistance
