UTILIZATION OF PIMA COTTON. 11 
The selling- of certain lots of seed cotton to the owners of the gins 
is practiced by some of the growers in the valley. This cotton, 
grown under different cultural methods and in some cases on land 
that is not well suited to the crop, is mixed, ginned, and baled with 
no precaution for the possible variation in length and strength of 
staple. This practice should be discouraged, for it is doubtless one 
of the causes of mixed packed bales. 
The cotton grown under the above-mentioned conditions does not 
have the same strength or length as that grown under favorable 
conditions. Under the present system this inferior cotton is picked 
and ginned with the cotton from the best parts of the fields. As a 
result the cotton of the best grade and character in the lot is classed 
with the inferior cotton, instead of the value of the inferior cotton 
being increased, as some growers believe. These inferior fibers pro- 
duce a weak yarn, so the manufacturer naturally assumes that the 
character and strength of the cotton are not suitable for high-grade 
yarns. 
One might put a high percentage of these inferior fibers into a bale 
of superior cotton and the cotton classer might not detect it, since the 
strong and the weak fibers have practically the same appearance, but 
when this cotton is manufactured into fine yarn the weak fibers 
show up readily. 
NEED OF FIELD SEGREGATION. 
If all the cotton grown under unfavorable conditions were put 
into one lot. a -fair price could be had for it, since there are certain 
classes of yarns into which it can be manufactured. Such a process 
of selection would reduce the amount of variation in the length and 
strength of staple in the same bale. The high percentage of waste 
would be reduced, for this inferior cotton would possibly be manu- 
factured into carded yarns only, while the superior cotton, contain- 
ing only a small percentage of short fibers, would be made into 
combed yarns. The number of mixed packed bales — that is. having 
cotton of three or four entirely different characteristics — would thus 
be reduced. 
Field classing and field segregation (2) would increase the value of 
the superior cotton and improve the demand for the better grades 
of Pima cotton, which would doubtless be equal to Sakellaridis for 
any class of fine yarns and fabrics, but as long as the cotton is 
picked and indiscriminately mixed the growers can not hope to 
receive the premium which the best grades will demand when 
properly selected. 
As regards the presence of several types of cotton in the same 
bale, an agent of a mill that is using Pima cotton, said: 
This sample shows four types. The smooth clean type represents cotton 
of this bale we can use in our very finest yarns and make fabric like the 
cutting inclosed. The rough, ropy type represents cotton objectionable for 
fine sheer goods, and the other two show cotton really unsuitable for use 
except in very coarse goods, which could just as satisfactorily be made from 
low-priced Peeler cotton. We might also say that the bale we refer to was 
received in a lot of bales, one-third of which lot was rejected, and our re- 
jection was approved by the shipper. 
The number of bales rejected is much greater in the case of Pima 
than in the case of imported Egyptian cotton. For example, a cer-
