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 ports consists of the regulation of 
the traffic from Mexico to prevent the importation, through accident 
or otherwise, of any Mexican 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.
