 three years prior to the discovery of tiie })ink bollworm have been

FEDERAL QUARANTINE OP TEXAS AND LOUISIANA. 



As long as the pink bollworm was believed to be confined to fairly- 

 limited districts within the State of Texas and these districts were 

 being adequately controlled by Federal and State authorities working 

 in cooperation, there was no vital need for the enforcement of a 

 Federal quarantine covering interstate movement of products out 

 of Texas. As already indicated, the altered outlook for 1920 

 pointed atrongly to the need of a Federal quarantine of Texas 

 and Louisiana to prevent the spread of the pest to other cotton- 

 growing States. The basis for such quarantine had already been 

 established by the public hearing, conducted in Washington on April 6 

 and 7. Follo\nng this hearing, and in view of the fact that the Federal 

 quarantine would probably modify or replace the quarantine action 

 which had been taken or which was bemg conteniplated by other 

 cotton-growing States with respect to Louisiana and Texas, it seemed 

 desirable prior to the issuance of a Federal quarantine to call a confer- 

 ence of all the cotton-grovv'ing States to consider and pass upon the 

 proposed Federal quarantine. Such conference was called at Wash- 

 ington July 14, 1920, and was attended by official and other rep- 

 resentatives of eight States, The preliminary draft of the Federal 

 action was carefully considered at this conference and a general 

 agreement was reached to harmonize the State action with the Fed- 

 eral action or to permit the Federal action to replace State quaran- 

 tines. 



The Federal quarantine of Texas and Louisiana on account of the 

 pink bollworm was promulgated July 21, effective August 1, 1920, 

 and was so drawn as to apply in its restrictions on the movement of 

 cotton and other articles to the areas kno'WTi to be infested or sus- 

 pected of possible infestation in the two States concerned, but this 

 limitation was conditioned upon the enforcement by these States of 

 effective control measures with respect to the crops produced in the 

 restricted districts. 



EFFECTIVE WORK NOT POSSIBLE UNDER NEW TEXAS LAW. 



The enforcement of the Federal quarantine under the new Texas 

 law has been far from satisfactory and has still fiu'ther fully demon- 

 strated the inadequacy of any control system looking to extermina- 

 tion other than that of the complete elimination of the growth of 

 cotton in invaded districts. As was to have been expected, scat- 

 tering infestation of cotton in the Trinity Bay district began to 

 develop in the late summer of 1920, and has now, October 1, been 

 rather widely determined tliroughout that district. The pink 

 bollworm act of 1920 provides for the prompt destruction of the
