the Coachella Valley in 1921. The 90 acres were rogued in turn and 
produced a supply of bulk seed which had been rogued for three 
successive years. This supply of seed was large enough to plant the 
entire Coachella Valley in 1922. A diagram showing the above- 
mentioned plantings and illustrating graphically the history of the 
seed stocks is shown as Figure 1. 
In 1921 another small Acala planting was made at the United 
States Experiment Date Garden, and one of the small fields of the 
year before was carried through the winter. Rogued seed of the 
Government date-garden crop of 1920 was used in making the plant- 
ing. Seed of five increase progenies, sent from Clarksville, Tex., 
where breeding work with Acala cotton had been carried on for a 
number of years by the Department of Agriculture, were included 
in the planting.

Seed produced by the first year's increase from a single plant 
is termed an "increase progeny," and these plantings constituted 
the beginning of an effort to improve the Acala seed stock of the 
Southwest. There was enough seed of each of the five increase 
progenies to plant one row about 200 feet long. In the fall indi- 
vidual plant selections were made from these five rows and also from 
the bulk field. 
DEVELOPMENT OF THE ACALA INDUSTRY IN 1922 
DISTRIBUTION OF ROGUED SEED FOR PLANTING IN 1922 
In order that the Coachella Valley might become a one-variety 
Acala community, it was hoped that all of the cotton growers would 
plant only seed produced by the 90 acres of Acala rogued in 1921. 
This seed was owned by three special growers and was offered to all
