TESTS OF OFFICIAL COTTON STANDARDS FOR GRADE. 5 
A study of Table II shows a close relationship between the per- 
centages of waste discarded in the manufacturing processes and the 
corresponding grades of cotton. The percentages of waste increase 
consistently as the grades of the cotton decrease in quality from Mid- 
ling Fair to Good Ordinary. The amount of invisible waste is com-

paratively regular, indicating uniformity in the moisture content of 
the cotton while it was being manufactured. In the manufacture of 
western upland cotton a somewhat increased amount of waste, as 
compared with the corresponding grades of eastern upland cotton, 
was discarded. However, these figures are not conclusive because 
they indicate the results obtained from the crop of only one year.
