ing the products produced therein in 1917, in extensive scouting to 

 determine at the earliest moment the occurrence of the insect in any 

 point in Texas or elsewhere, and in eradicative work. 



The work at the Texas border j)orts consists of the regulation of 

 the traffic from Mexico to prevent the importation, through accident | 

 or otherwise, of any ISIexican cotton seed. It includes the inspec- 

 tion and disinfection of baggage, the cleaning or disinfection of all 

 freight, express, and other shipments, except those which could not 

 possibly carry infestation, restrictions on the entry of railway cars 

 from Mexico, regulation of the transfer of freight, express, and 

 other shipments, certification of all cars or other carriers of mer- ] 

 chandise as a condition of entry into the United States (excepting ' 

 merchandise or other materials of strictly local origin), and the 

 cleaning of domestic cars as a condition of receiving freight originat- 

 ing in Mexico for movement into the interior of the United States. 



The work in Mexico consists of cooperation with the Mexican Gov- 

 ernment and the planters to stamp out the pink bollworm in that 

 country. The main infestation in the Laguna offers a hopeful oppor- 

 tunity for eradication on account of the loss which the pink bollworm 

 has already shown itself capable of causing, and the fact that the 

 cotton lands are owned by comparatively few persons. The other 

 two infestations in Mexico are on individual ranches where it may 

 be possible to have the planting of cotton abandoned for a series of 

 years beginning with 1919. The work in Mexico also includes an in- 

 vestigation of the life history and habits of the pink bollworm with 

 special reference to means of control.
