counties adjacent to the regulated area of the Panhandle district, but 
no new territory was involved. Intensive gin-trash inspections were 
made in the southeastern, central, and southwestern parts of Oklahoma, 
in almost all the cotton-producing counties of Louisiana west of the 
Mississippi River, and in the Delta counties of Mississippi. Inspec- 
tions were begun in northern Florida and progressed northward to 
the central parts of Georgia and Alabama. Results of inspection in all 
States were negative as to pink bollworm infestation with the excep- 
tion of Texas. Inspections in the Matamoros section of Mexico, 
opposite the lower Rio Grande Valley of Texas, revealed a heavy in- 
crease in pink bollworm infestation, 15,364 worms being taken from 
499 bushels of gin trash, whereas in the 1937 crop the average was 
slightly less than 2 worms per bushel. At Reynosa, Mexico, 9 pink 
boflworms were found in 322 bushels of gin trash as against none in 
the 1937 crop. 
A summary of the amount and results of the various kinds of inspec- 
tion is given in table 12.

WILD COTTON ERADICATION 
Especially good progress was made in the eradication of wild cotton 
in southern Florida, the first cleaning being completed in all areas in 
time to prevent any unusual amount of cotton from maturing seed. 
There was a decrease of 11,000 wild cotton plants from the number 
found last season in the Fort Myers district and a decrease of 67,000 in 
the Keys district. However, there was a small increase of wild cotton 
plants as a whole in the Ten Thousand Islands section, but a very 
decided decrease in the number of fruiting plants. The greatest in- 
crease was in the Cape Sable section — this being the largest continuous 
wild cotton area — where 362,000 wild cotton plants were destroyed, 
or about a 50-percent increase over last season. These facts are very
