Before recommending any continuing of such outlays, Dr. Strong hopes to 
determine whether such expenditures are justified or whether the time has come 
when the individual farmers should be left to carry on such control measures 
as they may consider advisable or required. All persons interested in pro- 
tecting the cotton industry of the United States from the pink bollworm are 
invited to attend the meeting and join in the discussion. 
NOTICE OF CONFERENCE TO DISCUSS THE STATUS OF THE PINK BOLLWORM 
infestation in cotton in the united states 
November 9, 1939. 
Since the pink bollworm of cotton was found in the lower Rio Grande Valley 
of Texas in 1936, it has become increasingly evident that the entire Cotton Belt 
of the United States is threatened by the presence of this infestation. Isolated 
infestations in other sections of the country have been found previously and 
exterminated and in other locations it has been possible to hold the infestations 
under control. In the lower Rio Grande Valley of Texas, however, the insect 
appears to have found surroundings particularly favorable to its development and 
the efforts made to suppress this infestation have been only part ally successful 
and it has been noted there has been enough survival each year to explain some 
increase in the distribution and density of the infestation. 
A special effort was made to clean the fields and destroy crop residues through- 
out this area in the United States and in Mexico during the crop season of 1939 
and it is not possible at this time to definitely determine the results of those 
efforts on future infestations. However, it seems desirable to give consideration 
to any further steps that may be taken to combat this pest with particular refer- 
ence to the infestation occurring in this region. From past experience the most 
effective procedure would be to have a noncotton zone. The cost of such a pro- 
gram or an alternative program of continued clean-up means huge outlays of 
Federal and State funds. The determination must be made whether these huge 
outlays of public funds are justified or whether the time has come to depend 
upon the individual farmers to perform such control work as they may consider 
advisable or required. To consider these questions a public conference is hereby 
called to meet at 10 a. m. on December 15, 1939, in the Little Theater, San Pedro 
Park, San Antonio, Tex. All of those interested in the protection of the cotton 
industry of the United States from the spread of the pink bollworm of cotton are 
invited to be present and join in the discussion.

COTTON QUARANTINE AGAIN EXTENDED IN TEXAS 
[Press notice] 
November 17, 1939. 
Additional infestations of the pink bollworm of cotton have been found in new 
localities in Texas, in the vicinity of San Angelo and at other points in the sur- 
rounding area, the United States Department of Agriculture announced today. 
The Federal quarantine regulations were accordingly extended effective Novem- 
ber 20, to include the Texas counties of Concho, Irion, Mitchell, Sterling, Tom 
Green, and that part of Coke County lying southwest of and including the right- 
of-way of Highway No. 87. The regulated area is now comprised of 49 Texas 
counties and parts of 3 others in that State, 6 entire counties and part of another 
in Arizona, and 12 in New Mexico. 
MODIFICATION OF PINK BOLLWORM QUARANTINE REGULATIONS 
Introductory Note 
The recent finding of pink bollworm infestations in the vicinity of San Angelo, 
Tex., and at points in the surrounding area again necessitates an extension of 
the regulated area. Under this amendment there is added the entire Texas 
counties of Concho, Irion, Mitchell, Sterling, and Tom Green, and that part of 
Coke County lying southwest of and including the right-of-way of Highway No.
