gested. Inspectors should be appointed to see that these laws are 
faithfully carried out. In case they are not properly complied with at 
once the inspectors should have power to hire this work done, and 
attach the property for compensation to the State. In this way only 
can we hope to secure concerted action, and without concerted action 
all efforts to subdue the pest will be in vain. 
Compulsory abandonment of cotton growing on the border. — The rea- 
sons why cotton growing should be abandoned on the Texas border 
have already been fully detailed and are very cogent. Laws should be 
passed decreeing the Rio Grande border of Csxas for a width of ."30 
miles to be a non-cotton-producing belt, compelling all persons to aban- 
don the raising of cotton in that area, and providing for the destruction 
of all cotton plants (and other malvaceae, if such exist) within the 
same. If, by the greatest good judgment and most efficient and con- 
certed labor, the weevil is exterminated in the present infested districts 
in Texas, and this non cotton zone fails to be established on the border, 
fresh importations will occur constantly, and all the labor will have to 
be performed over again. The only alternative lies in Mexico extermi- 
nating the weevil within her borders, which it will be almost impossible 
for her to do, as that is its natural home and its original food-plants 
probably exist there in quantity. 
Cotton growers .should organize. — Cotton growers in the State of 
Texas, in both the infested and the uniufested regions, should organize 
at once and petition the State legislature to j)ass suitable laws for the 
extermination of the pest within the limits of the State, and for the 
establishment of a non-cotton border zone. Growers in the infested 
region should desire to rid themselves of the pest, while those in the 
uniufested region should be equally interested in preventing its further 
spread and preserving their fields from its attack. If these measures 
are not carried out, the time is near when Texas will cease to hold its 
own as the greatest cotton-producing region of the globe.
