successful fumigation of cotton seed with hydrocyanic acid gas 

 at a strength that will kill all boll weevils, but which will not 

 impair the germinating power of the seed. This method, while 

 too expensive to employ in a commercial way at present, is 

 being employed in the fumigation of seed of early varieties of 

 cotton from the weevil-infested territory when it is necessary to 

 lake tli is seed to the non-infested sections for experimental or 

 demonstration work. The danger of disseminating the weevil 

 vith such seed is thereby eliminated. 



COTTON SEED OIL MILLS. 



During the past year the Commission has devised a method 

 ly which cotton seed oil mills can handle their hulls, after these 

 leave the huller, in a manner which will effectually prevent the 

 dissemination of boll weevils with them. To oil mills in the in- 

 fested territory, arranging and screening their shakers and con- 

 veyors in the manner required by the Commission, permits are 

 given for the shipment of hulls to the non-infested territory. 

 This arrangement permits an unhampered outlet for the hulls 

 without endangering the localities through which, or to which, 

 the hulls may go. 



THE SAN JOSE SCALE. 



As mentioned on a previous page, the State Legislature, 

 when enacting the Crop Pest Law of the State, very wisely pro- 

 vided for the control of insect pests other than the boll weevil. 

 Up to the present time the damage by the latter insect, in Louisi- 

 ana, has not exceeded that done by the San Jose scale, a serious 

 enemy of such fruits as peach, pear, apple, plum, etc. This in- 

 sect and its destructiveness, the remedies for it, etc., are dis- 

 cussed in Circular No. 4 of the Commission, copy of which is
