of Burke County to Hickory im’ Catawba mty, where it tends southeastward through Catawha and Iredell Counties. It passes into 
Rowan County two miles south of Mt. Ulla, continues through Rowan County, and passes through the southeastern corner of Rowan County 
just touching the south end of Davidson County and passing through Ophir in Montgomery County. It then tends northeastward through 
southeast Randolph County and through Rives Chayel in Chatham County, continuing eastward through a point 4 miles south of Eacle 
Rock in Wake County through northern Johnson County, and throngh Wilson in Wilson County. ‘The line continues eastward through 
the extreme southern portion of Edgecombe County, through Pitt County, and through a point 3 miles north of Washington in Beaufort 
County and then southeastward into Pamlico River. | 
In Florida the line passes Ozano in Pinellas County, Tampa, Sefiner, and Plant City in Hillsborough County, Fort Meade in Polk 
County, Kissimmee in Osceola County,-and Indian River City in Brevard County. , 
Extensive inspections continued throughout the season failed to reveal any weevils in El Paso, Hudspeth, Ward, Reeves, and Pecos 
Counties in Texas, and Dona Ana, Eddy, and Chavez Counties in New Mexico. The situation in Arizona remains the same as last year, 
except that specimens of the Thurberia weevil have been found in a cotton field at Continental. 
Altogether 66,662 square miles of new territory were invaded by the weevil in 1921 and there was no loss of territory at any point. 
This makes a total of 600,771 square miles infested in the sountry. The figures fer 1920 showed a total of 73,000 square miles uninfested 
in the cotton belt, but this figure was based on a cotton-belt area of approximately 607,000 square miles. Recent extensions in cotton 
plantings have made it necessary to correct this figure. The territory now included in the cotton belt comprises about 705,000 square 
miles. Consequently about 105,000 square miles of cotton territory are still uninfested.

From this it is seen that only 5.4 per cent of the cotton crop of the cotton belt is produced in the area not infested. Since practically 
15 per cent of the cotton belt is still uninfested this percentage emphasizes the scattering plantings of cotton in this outlying territory. 
We are indebted to Prof. Franklin Sherman of the North Carolina Department of Agriculture for assistance in determining the line in 
that State, :
