Not only is Pima cotton being used successfully in tire yarns and 
in airplane and balloon fabrics where strength and elasticity an 
the chief requisites, but it also is being manufactured satisfactorily 
into line yarns, handkerchiefs, fine shirtings, dimities, lawns, and 
voiles. Some mills have woven commercial fabrics of 120s warp 
and 160s filling from Pima cotton. The writer was in a plant that 
is spinning 130s filling, using for twist multiplier less than two 
times the square root of the number of yarn being spun, which means 
an increase in production for the mill. 
One mill that is using Sea Island. Peelers, and Pima cottons is 
getting a break of 22 pound- per hank on 100s ring spun. The 
spindle speed used in this case is the same as that used for 85s 
Peeler in this plant. 
OBJECTIONS CURRENT AMONG MANUFACTURERS. 
During a recent investigation in the New England manufactur- 
ing district many questions regarding Pima cotton were brought 
to the writer's attention by persons who have had experience in the 
use of this fiber. However, the possibilities of using Pima cotton for 
general purposes has not been fully determined, owing to the short 
time that has elapsed >ince it was decided to promote the general 
uses of this variety. Many mill- that can n>e this staple have never 
heard of Pima cotton and therefore have conducted no tests to de- 
termine its working qualities, while there are many unwarranted 
statements in circulation among those who have had no direct con- 
tact with this cotton. In several case- the manufacturers admitted 
that their opinions relative to the value of the cotton were based 
upon hearsay. Some of these objections would be serious if they 
were well founded, while others can he traced to deficiencies in the 
methods of production and handling the crop. Xow that these 
objections have been brought to the attention of the grower-, efforts 
are being made to correct these imperfect methods 
The most serious objections offered by the manufacturer- of Pima 
cotton are as follows : 
P i Too ?rear variation in length of sraple. 
il'i Poor ginning and rough handling. 
i .". i High percentage of waste. 
(4i Mixed packed bales. 
< 5 i Too many neps. 
(6) Production oe card reduced. 
i 7 i Considerable amount of " fly."

that the variation in length of the staple is too great. One manu-
