BULLETIN 1467, U. S. DEPARTMENT OF AGRICULTURE 
The accurate figures have all been given in the text covering the dif- 
ferent years and appear also in the tables. 
All of the fields rogued in the Coachella Valley in 1925 had been 
planted with seed increased from a single plant selected from the 
1922 breeding block. The 87 acres rogued produced 105 bales, which 
gave about 50 tons of seed, an ample supply for planting the entire 
Coachella Valley in 1926. The cotton from the rogued fields was 
stored in a special house and ginned only after the gin machinery 
had been thoroughly cleaned, as already described. This precau- 
tion is desirable with the rogued seed even in a one-variety com- 
munity. 
The rogued-seed data for 1925 are shown in Table 5 (p. 41) in 
comparison with similar data for previous years. 
The general quality of the 1925 crop was much improved, since the 
entire cotton acreage of the valley had been planted with new -stock 
seed increased from the best progeny row of the 1922 breeding block 
and rogued each year. Thus the seed for planting the entire cotton 
acreage of the valley in 1926 was the increase from a single plant 
selected from the 1922 breeding block. Through the community 
association this improved seed will be made available to other cotton 
districts. 
TABULATION OF DATA 
Statistical data of the Coachella Valley community project in 
growing Acala cotton are presented in Tables 1 to 6, inclusive. 
Table 1 gives the acreage planted in each variety of cotton from 
year to year and shows the yearly progress in establishing Acala as 
the sole variety grown in the community. The gradual elimination 
from the valley of the contamination of Acala seed by other var- 
ieties and the attainment of 100 per cent of Acala grown on land 
that was clean and isolated are shown in Table 2. Statistics of cot- 
ton and seed producton and of cost and sales of seed appear in the 
other tables.

1 The figures for 1920 and 1921 are approximate, being based on the number of bales ginned. The figures 
for other years were determined by an actual survey of the acreage. 
2 Includes 62 acres of ratoon cotton.
