UTILIZATION OF PIMA COTTON. 23 
of farmers and manufacturers who are desirous of having a regular 
supply of uniform cotton to encourage the production and promote 
the use of Pima cotton. 
During 1921 special supervision was given to the ginning and 
grading of approximately half of the crop. The cotton was graded 
and classed in uniform lots according to staple, which proved advan- 
tageous to the manufacturers. Plans are being formulated to pro- 
duce a more uniform lot of cotton from the 1922 crop. 
IMPROVEMENTS FOR THE STABILIZATION OF PIMA COTTON. 
A conference, attended by bankers, growers, members of the State 
Farm Bureau Federation, and members of local organizations, was 
held in Phoenix, Ariz., April 4 to 6, 1922, for the purpose of formu- 
lating plans for the improvement of growing, handling, and pro- 
moting the use of Pima cotton. The necessity of bettering conditions 
in the industry by improving the methods of growing, ginning, 
baling, and storing was recognized, and the following recommenda- 
tions by the committee were adopted by the conference: 
Planting- pure, selected seed on land especially suited for cotton production. 
The most advanced cultural methods. 
Field segregation and classing. 
Careful picking and handling to avoid mixing types. 
The most improved methods of ginning, baling, and storing. 
Careful sampling and efficient classing as to grade, staple, and type. 
Proper warehousing or other protection to prevent country damage. 
Intelligent compressing not injurious to this type of cotton. 
The delivery to t-he manufacturer of cotton in well-covered bales in a de- 
sirable condition, equal to that of any cotton placed on the market. 
THE VAEIETY GROWN. 
It is recommended that the production of Pima cotton be continued until 
there is satisfactory evidence that some other variety can be grown more 
profitably. The fundamental importance of growing only one kind of cotton 
is recognized, and it is believed that haphazard experimentation with other 
varieties is bound to result in mixture of seed and loss to the community of 
its reputation for producing a uniform and superior cotton. It is strongly 
urged that if at any time in the future a change to some other variety should 
be deemed advisable the substitution should be made in an orderly manner 
and with due precaution to avoid mixture of seed. 
THE PLANTING SEED. 
Recognizing the fundamental importance of pure planting seed as a requisite 
to the production of uniform cotton of superior quality, we recommend the 
continuation of the present method of maintaining purity of the planting seed 
by roguing seed fields, increasing the seed from the rogued fields under proper 
conditions of isolation, and distribution of the seed from the increase fields 
to the growers under certification. 
We also recommend that the cost of providing a supply of certified planting 
seed adequate for all contingencies be distributed equitably among the cotton 
growers of the Salt River Valley. 
UNIFORMITY IN THE BALE. 
We recognize that under existing conditions much of the cotton produced 
has reached the consumer in bales the contents of which lack uniformity; 
in other words, that in many cases all of the cotton in the bale is not exactly 
like the sample. 
We recommend the inauguration of a system of field segregation, gin in- 
spection, and bale certification, to the end that the individual bale shall be
