By matching the samples of yarn dyed in 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 slightly superior to the 
Sakellaridis 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 Sakellaridis 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 
filling Egyptian, or vice versa. The grade of cotton used is, of course,
