33.S91 grammes. Length of fibre ist test, 35.6 millimeters : 2d test, 

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

 Average lengtli, 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 bliglited. 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 bliglited 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, i3-ooo 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 

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

 fibre was 0.016 to 0.024 'niHinieters, the last measure predominating. 

 The twist was about an average and tlie length ranged from iS milli- 

 meters to 20. S millimeters. Average 1S.5 millimeters. The resistance 

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

 grammes. This is a good grade of cotton, with 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 0024 millimeters. Length: 21.6, 

 23.2, 21.2,22.4 111 illi meters. Average 22.1 millimeters. Resistance
