MANUFACTURING TESTS OF COTTON

There are certain factors which can not be included in any formula 
for determining the value of grade. For example, a mill may have 
built up a trade on converters ' goods, in which bleaching and finishing 
qualities are chief requisites. In such cases the use of low grades 
may be inadvisable, even though the prices are materially lower than 
those for high grades. But if the product is for other uses where

GRADE NUMBERS 
Fig. 13.— Average price of cotton by grade and estimated prices of waste from cotton of the several 
grades. Relative values of grades are based on five-year averages as of the first day of each 
month, September, 1920, to August, 1925. The relative values of waste are based on estimates 
as of August, 1925, obtained by personal interviews with waste dealers and cotton manufacturers 
bleaching is not a chief requisite, the low grades might be used more 
advantageously in case the spread in prices between grades was 
great. 
The formula will show the immediate monetary difference between 
the grades, but the choice of the grade must rest upon the discretion 
of the management of the mill. 4 
* Valuable suggestions regarding this formula have been received from R. E. Loper, specialist in textile 
cost service and William Smith, principal, New Bedford Textile School.
