spring are usually found about gins and seed houses. Hence it will 
be advisable to plant short rows of cotton near these places; also about 
houses, feed lots, and stock sheds, especially if the cattle have been 
fed freely on cotton seed. Trapping the weevils here prevents their 
spreading to the fields. 
Timbered sections afford ample opportunities for the weevil to hide, 
and hence trap rows should be planted along the edges of the woods, 
alongside of or surrounding the cotton fields. (See fig. 4.) 
For the field planting of trap rows it has been found fully satisfactory 
to plant a row or two across the middle of every 20 acres, or at that 
rate. 
By giving careful attention to the location of trap rows many weevils 
can be congregated and destroyed before they reach the cotton fields. 
Should the planting season be so unfavorable as to make it impracti- 
cable to properly employ the trap-row plan, then it will be especially 
advisable to resort to picking the cotton abso- 
lutely clean of all squares as soon as it is evident 
that all of the hibérnating weevils have issued. 
Then follow this immediately with a thorough 
spraying, using the stronger solution recom- 
mended for the trap rows. Under these cir- 
cumstances the weevils will be largely gathered 
and destroyed. At the same time those which 
escape being gathered, finding no squares, will 
be tempted to eat of the poison more freely, 
which will insure the greatest possible destruc-

tween the boll and the Treatment and management of the trap rows.— 
Sch Pa ‘‘T Once the weevils are congregated on the trap 
rows, advantage can be taken of their habit of 
of ‘‘ playing possum” when disturbed or frightened. ‘To profit by this 
habit, tests were made of a plan to use pans, and, bending the plants 
over them, to shake the plants vigorously, repeating this operation 
from plant to plant along down the row. The pans should be previously 
smeared on the bottoms and along the sides with coal tar or some other 
adhesive substance. Much depends on the operator. Careful inspec- 
tion of the rows thus treated showed that from 60 to 95 per cent of all 
weevils on the plants could thus be shaken off. This work carefully 

done, when confined to trap rows only, is entirely feasible, also eco-— 
nomical, and very effective. This shaking method becomes impracti- 
cable if an attempt is made to apply it to large plantations. For 
small fields of from 5 to 15 or 20 acres there is no more certain, eco- 
nomical, and effective method. It should be used for the trap rows 
especially, and for small fields.
