UTILIZATION OF PIMA COTTON. 17 
arbitration, should that be necessary, while the other half would be 
submitted to the prospective buyer for his examination. In order 
to make this plan effective it would be necessary that the organization 
guarantee that the sample is representative of the contents of the 
bale. It may be noted from the photographs of bales (figs. 2 to 5) 
that many of the cuts made in sampling are not patched at the com- 
press, causing a considerable loss to the growers. 
COMPRESSING. 
A step in handling of no less importance than sampling is com- 
pressing. A few y ears ago some of those interested in the manu- 
facturing of tire fabrics claimed that Pima was " air cut " when 
compressed. This question was taken up with the various manu- 
facturers in the Xew England district, and it is the consensus of 
opinion that this cotton can be compressed at a slow rate to a density 
of 22 pounds per cubic foot or slightly more without any damage 
to the fiber. 
One of the Xew England mills which is using much Pima cotton 
has just completed a test for the growers of Arizona on five bales 
(Grade Xo. 2) of compressed Pima cotton. Its report is as follows: 
The spinning value of this cotton has not been injured in the compressing of 
these bales ; in fact, they were a very good lot and better, in our opinion, than 
the average run of this cotton, as the test will show. The waste from all 
sources showed 32.367 per cent, and of this amount there was 0.01879 per cent 
of invisible waste. 
Many other mills which the writer visited are using compressed 
Pima cotton, which is working satisfactorily so far as this matter 
is concerned. The advantage to the mills is considerable, in that 
much less space is required for storage, but it is of more importance 
to the growers in what they save in transportation and storage 
charges. Under the growers' present plan of storing the cotton in 
the East until a market can be had the question of rates on com- 
pressed as compared with uncompressed cotton should have first 
consideration. For example, the rate for storage is 85 cents for the 
first month and 45 cents for each month thereafter for uncompressed 
cotton, while for that compressed the rate is 55 cents for the first 
month and 25 cents for each month thereafter. 
The freight rate on compressed cotton is $2.08-| per 100 pounds, 
while the rate on uncompressed bales is $2.44-|. Much of this cotton 
is stored in the East for more than three months. The charges on a 
500-pound bale stored for three months only are as follows : 
Uncompressed cotton : 
Freight, 5X2.44* per 100 pounds $12.22* 
Storage, first month . 85 
Storage, second and third months at 45 cents . 90 
Total charges 13. 07* 
Compressed cotton : 
Freight, 5X2.08* per 100 pounds 10.42* 
Storage, first month . 55 
Storage, second and third months at 25 cents . 50 
Total charges 11.47* 
Saving per bale 2. 50
