the method. This practice comes as near being absolutely eradicative 
in its results as any that has been tried. Just in proportion as it is 
applied will the cost of the weevil campaign in spring be dimin- 
ished. Its application costs nothing, for, as a matter of fact, it is 
applied at a time when pastures are short, and so far as the stock is 
concerned, the practice is of positive advantage. There is one pre- 
caution to be observed, and that is to make sure that a good drenching 
rain has followed the last application of any poisons to the cotton. If 
such has been the case, there is positively no danger to the stock from 
grazing it. 
TRAPPING THE WEEVILS INTO HIBERNATING QUARTERS. 
After the cotton stalks have been divested of foliage and squares by 
erazing, they should be pulled, cut down, or plowed out, and piled in 
windrows across the field and allowed to remain to dry thoroughly. | If 
any weevils have escaped the grazing process, they will collect in this 
rubbish for hibernation instead of going out to the timber and rubbish 
along fences, highways, and byways. In this manner the escaping 
weevils are actually trapped into hibernating quarters just where you 
want them. When this has been accomplished set fire to the wind- 
rows and burn up stalks, rubbish, weevils, and all. This method, 
coupled with that of grazing, as outlined, can have no other result than 
practical eradication. 
It should be stated that allowing the stalks to remain standing dur- 
ing the winter and then gathering and burning: does not have the 
desired effect, because the weevil does not and can not utilize them for 
protection while thus standing, and hence goes elsewhere for shelter. 
For this reason, also, windrowing the stalks after frosts does not have 
the desired effect, since it does not act as a trap during the period 
when they are seeking winter quarters. Previous to windrowing the 
cotton stalks, corn and stubble fields should be burned; also anything 
else which could afford the weevils protection. Just how to proceed 
with the labor of windrowing the stalks must be a matter for each 
planter to determine. 
As soon as possible after all rubbish has been burned, the fields 
should be plowed as deeply as practicable, for two reasons: (1) To 
plow under and destroy all the squares and rubbish yet on the ground 
makes it impossible for any larve to mature and produce weevils: 
(2) it breaks up the cells in which the bollworm transforms during 
winter, thus destroying them also. 
IS THE BOLL WEEVIL MIGRATORY? 
The above question is suggested by the fact that the cotton-growing 
territory of the State invaded by this pest from its first spread across 
the Mexican border is now practically free from it. This freedom is 
coupled with the idea in the minds of the planters that the weevil
