Individual fibers of these cottons were also measured by the pro- 
jection device originated by Dr. N. A. Cobb of this department, and 
it was found that the ratio of lengths between the estimated lengths 
and the actual measurements was relatively uniform. 
Samples of this cotton were sent to certain reputable cotton bro- 
kers who deal in staple cotton to ascertain the comparative com- 
mercial value of each bale on the same day. Data were given these 
brokers regarding the origin of each bale of cotton, so that all factors 
influencing the commercial value could be considered. Table III 
shows the result of this inquiry.

WASTE COMPARISONS. 
The results obtained from the tests, already described, to deter- 
mine the amount of waste in each kind and variety of cotton are 
shown in Table IV. This table gives the waste percentages based on 
the amount of cotton fed into each machine. The tare on the bales 
of cotton was not included in any case.
