community, fields of another variety might be adjacent to an asso- 
ciation member's Acala field, thereby disqualifying the Acala seed 
for planting purposes, reducing the association's production, and 
increasing the overhead expense. Also a wider use of the rogued 
Acala seed would have led to a greater improvement in the general 
quality of the valley cotton crop. 
The distribution of the rogued Acala seed in the Coachella Valley 
in 1922 showed conclusively that asking a high price for the local 
planting seed, though it may increase the current year's returns, 
may retard materially the attainment of a one- variety community. 
ACREAGE AND VARIETIES GROWN IN 1922 
There were 1,259 acres of cotton planted in the Coachella Valley 
in 1922, an increase of about 28 per cent over the 1921 acreage. 
The acreage planted to the Acala variety, however, increased from 
approximately 300 acres in 1921 to 1,071 acres in 1922, an increase 
of 257 per cent. The Mebane acreage decreased from approxi- 
mately 300 acres in 1921 to only 17 acres in 1922. The Durango 
variety, however, did not give way to Acala so rapidly, the decrease 
being from approximately 300 acres in 1921 to 171 acres in 1922. 
Acala constituted 85.1 per cent of the valley cotton acreage of 1922, 
Durango 13.6 per cent, and Mebane 1.3 per cent. The above data 
are also given in Table 1 (p. 40) in comparison with the same data 
for other years. 
Durango had been very satisfactory in many respects, and growers 
who had done well with it were reluctant to abandon it. The final 
decline in the Durango acreage in California was due more to the 
lack of a satisfactory seed supply than to any other factor. Private 
individuals and companies were in the Durango seed business for 
a few seasons, and their seed in some instances was held at high 
prices, but it proved unsatisfactory in uniformity, so that the farm- 
ers stopped buying it. Had there been an organized and successful 
Durango community so that the seed could have been protected 
from mixture, and the necessity for relying on the more or less 
sporadic efforts of private individuals for a seed supply thus 
avoided, good seed of this variety in all probability would still be 
available and would be planted to a considerable extent. 
CLASSIFICATION OF ACALA SEED IN 1922 
The efforts of the Acala Cotton Growers' Association of the 
Coachella Valley toward the establishment of a one-variety Acala 
community and the natural advantages of the Coachella Valley 
for the community production of commercial quantities of pure 
seed enabled the association to obtain the cooperation of the Depart- 
ment of Agriculture from the inception of the Acala industry in 
the valley. The rapidly expanding demand for Acala seed and the 
importance of a supply of good planting seed in establishing the 
cotton industry on a better and more permanent basis in the South- 
west made it important that this cooperation be continued and 
even extended. 
From its experience in 1921 the association realized the disad- 
vantages of selling more than one grade of seed, and in 1922 it
