variety. The valley cotton growers recognized the advantages of 
the rogued seed, and since the price was not prohibitive they all came 
to the association to procure their planting seed. Since all of the 
rogued seed distributed for planting in 1925 consisted of the new 
stock, production of this improved cotton was established on the 
basis of the entire valley, with the exception of a few acres ratooned 
from the year before. It can be stated definitely in the light of pre- 
vious experience that if the new-stock rogued seed had not been made 
available to the valley at cost the valley-wide substitution of the new 
and improved stock for the original stock would not have been so 
completely successful. 
The 1925 cotton acreage of the Coachella Valley is shown in Table 
1 (p. 40) in comparison with acreage data for previous years. 
CLASSIFICATION OF ACALA SEED AND GINNING IN 1925 
Since for two years Acala had been the only variety grown in the 
valley and rogued seed of the new stock had been used for all the 
cotton planted in 1925, the problem of classifying the Acala seed 
was now considerably simplified. 
In 1925 the only cotton of the original-stock Acala left in the 
Coachella Valley consisted of a few acres ratooned from the year 
before. Very little of the original-stock cotton had been ratooned in 
1925, since most of the growers who might have ratooned preferred 
to replant their fields with new-stock seed rather than ratoon the 
original-stock cotton. Ratooning was also discouraged by a regula- 
tion issued by the association to the effect that it would not save seed 
from ratooned fields. Seed from ratooned plants is genetically as 
good as seed produced the first season after planting, but cotton 
ratooned in 1925 would have consisted partly of the original stock, 
so the practice was discouraged entirely. Also the danger from 
noxious weed seed is greater with fields of ratooned cotton than with 
fields that have been plowed and replanted, unless the ratooned cotton 
has been very well cared for. 
The gin machinery was cleaned whenever cotton from which the 
seed was to be saved followed a bale from a ratooned field of the 
original stock. But the gin machinery did not have to be cleaned 
very often, since ratooned cotton matures much earlier than planted 
cotton and a large share of it is ginned before much of the planted 
cotton has been picked. 
The season of 1925 was considered rather unfavorable for cotton 
in the Coachella Valley. The crop was later than usual, but the final 
production was 3,685 bales from 4,227 acres, an average yield of 
0.8T of a bale to the acre, which is very satisfactory. One of the 
features of the Acala variety is its ability to continue growth in the 
fall and produce a crop when more determinate varieties have 
stopped growing. The 1925 yield data from the valley are also given 
in Table 3 (p. 41) in comparison with similar data for previous 
years. 
SALE OF ASSOCIATION SEED, CROP OF 1925 
The planting seed made available to other districts by the Acala 
Cotton Growers' Association of the Coachella Valley now consisted 
entirely of an improved stock. This stock was of a better type and
