BULLETIN 1148, U. S. DEPARTMENT OF AGRICULTU 
VARIETIES OF COTTON TESTED. 
RE. 
The following varieties were tested: Acala, Lone Star, Mexican Big 
Boll. Rowden, 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 vilie, 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.
