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 j^arns they manufactured. These results are shown in 

 Table V, under lots No. 3 and No. 4. 



CHEMICAL LABORATORY TESTS. 



Investigations also w-ere made in the laboratory of the New Bed- 

 ford Textile School ^ 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 :
