AC ALA COTTON IN CALIFORNIA 29 
Since it would be necessary to keep the original-stock seed from 
being mixed with new-stock seed at the gin and the cotton from 
fields previously planted to other varieties from being mixed with 
either of them, the gins were furnished with a list of all growers, 
designating for each grower the number of acres and the character 
of the cotton grown. 
The new-stock seed used in planting 926 acres in 1924 had been 
increased from a single row grown in 1921. This row had furnished 
enough seed for planting an acre in 1922, which was rogued and 
furnished seed for 27 acres in 1923. The 27 acres were rogued and 
produced the seed used in making the 1924 planting. The original- 
stock seed planted in 1924 had now been rogued for five successive 
years. 
GINNING IN 1924 
In 1924 there was no danger of the Acala seed being mixed with 
other varieties at the gin, but the gin machinery had to be cleaned 
in order to avoid mixing the two stocks of Acala and to prevent both 
stocks from being contaminated by Acala seed from fields that had 
previously grown other varieties. 
Arrangements were therefore made for the gin machinery to be 
thoroughly cleaned whenever a bale of Acala from which the seed 
was to be saved followed a bale of Acala from fields previously in 
other varieties, and the rolls were dropped whenever a bale of new- 
stock cotton followed a bale of the original-stock cotton. A list of 
all the valley growers, designating the treatment to be accorded each 
grower's cotton, was furnished the gins. Separate bins for receiving 
the new-stock and the original-stock seed were erected at the gins. 
Since seed was not saved from the entire Coachella Valley cotton 
acreage, it was not necessary to clean the gin machinery as frequently 
as might have been expected. 
It was unfortunate that two stocks of Acala were grown in the 
valley during 1924, but it could not have been avoided unless the 
new-stock seed had been held up for a year. It seemed a much more 
desirable course to put as much of the improved seed into production 
as possible and suffer the inconveniences of properly taking care of 
it. The situation developed because the 1922 breeding block, though 
adequate for the 1,259 acres of cotton then grown, was not large 
enough to furnish seed for planting a rogued acreage in 1923 of 
sufficient size to furnish seed for the 4,818 "acres of cotton grown in 
1924. After 1922 the breeding block was enlarged to take care of 
this deficiency. 
A total of 4,527 bales was ginned from the 1924 crop. This gave 
an average yield for the valley of 0.94 of a bale per acre, and since 
Acala was the only variety grown, this figure indicates the behavior 
of Acala under the valley conditions. A yield of nearly a bale to 
the acre for an entire community, which of course includes a con- 
siderable quantity of poor cotton, can be equaled in only a few dis- 
tricts. Yields of 1% bales of Acala cotton per acre, when grown 
on good land and properly cared for, are of frequent occurrence 
in the Coachella Valley, and yields of 2 bales per acre and over are 
not uncommon,
