By matching the samples of yarn dyed m the exhaust baths 

 against the above standards the results shown in Table XVII were 

 obtained.

From Table XVII it will be seen that the Arizona-Egyptian cotton 

 samples 1-4 gave better results in mercerizing than any of the others, 

 the nearest approach to it being that of sample 6, Sea Island cotton. 



These laboratory tests show that after bleaching, dyeing and 

 mercerizing, the Arizona-Egyptian and Sea Island cottons were 

 practically equal to each other and were shghtly superior to the 

 SakeUaridis Egyptian in their bleaching and mercerization properties; 

 that they were fully the equal in dyeing properties, possibly ranging 

 slightly in favor of the Sea Island and SakeUaridis in tensile strength. 



DIFFICULTIES IN INTRODUCING A NEW VARIETY OF COTTON. 



The manufacturer usually secures a contract for goods before they 

 are manufactured, but when offering a fabric or yarn for sale, manu- 

 factured from a new kind of cotton, difficulties frequently are met 

 with from the buyer or converter who, when placing a contract or 

 an order for fine goods, specifies the kind of cotton required, that is, 

 American, Egyptian, or Sea Island. In a large number of instances 

 on cloth orders, the warp required is of American cotton and the 

 fillin g Egyptian, or vice versa. The grade of cotton used is, of course,
