VARIETIES OF COTTON TESTED. 



The following varieties were bested: Acala, Lone Star. Mexican Big 

 Boll. Rowdcn, and typical North Georgia. All of the cotton was 

 obtained from men of reputation for their plant-breeding work, with 

 the exception of the typical North Georgia cotton, which was bought 

 from a prominent cotton merchant as typical "North Georgia" cot- 

 ton. This type of cotton always commands a premium over other 

 cotton of the same grade and length of staple. 



ORIGIN OF THE COTTON. 



The Acala cotton consisted of 7 bales grown near St. Clair, Lowndes 

 County, Ala.; the Lone Star consisted of 4 bales grown near Fay- 

 ette ville. N. C. ; the Mexican Big Boll consisted of 4 bales grown near 

 McFarland, N. C. ; the Rowden consisted of 4 bales grown near 

 Monroe. N. C; and the typical North Georgia cotton consisted of 4 

 bales bought from a merchant in Athens, Ga. The exact origin or 

 history of the typical North Georgia cotton is unknown, except that 

 it came from that region known commercially as typical '"North 

 Georgia " territory. 



CLASSIFICATION OF THE COTTON. 



Samples of cotton from the different bales were classed by a com- 

 mittee of the board of examiners. This committee is authorized to 

 class cotton at the future exchanges under the provisions of the 

 United States cotton futures act. The results of this classification 

 are shown in Table 1.

MECHANICAL CONDITIONS. 



The five different varieties of cotton were run under identical 

 mechanical conditions, which conformed to common mill practices 

 for the grade and length of staple used. 



PERCENTAGES OF WASTE. 



Accurate weighings were made of the net amount of cotton fed to 

 and delivered by each cleaning machine and of the net amount of 

 waste discarded by each. From these weighings the percentage of 

 visible, invisible, and total waste were determined. The percentages 

 of waste for each variety are shown in Table 2.
