MANUFACTURING TESTS OF COTTON. 
shown in Table VI. The results of the single-thread tests are re- 
corded in ounces, while the tensile strength in pounds per skein of 
the yarn taken from the same bobbins from which the single-thread 
tests were made is also given. In all cases where the skein tests are 
given in connection with the single-thread tests, the yarn was taken 
from the same bobbins.

The single-thread tests, judged from the comparative uniformity 
of breaks, did not disclose any superiority, either in the yarns made 
from the fumigated or from the nonfumigated cotton. 
Two of the mills reported their findings as to the tensile strength 
of the cotton yarns they manufactured. These results are shown in 
Table V, under lots No. 3 and No. 4. 
CHEMICAL LABORATORY TESTS. 
Investigations also were made in the laboratory of the New Bed- 
ford Textile School 1 to ascertain whether cotton treated with hydro- 
cyanic-acid gas lost any of its bleaching, dyeing, or mercerizing 
value. The following numerical designations represent the cotton 
and cotton yarns used in these laboratory tests :
