For the purposes of this article Mr..
| Hunter has furnished the following
interesting statement relative to the
boil weevil:
THE boil weevil will undoubtedly
reach the border of Georgia during
the present season and may extend it's
range some little distance within the
state. If it had not been for rather
unusual circumstances the invasion of
Georgia would have been extensive.
Among these circumstances was an
early frost in 1913 which killed many
of the weevils and drove others into
Information far ahead of the usual
date. Many Of these weevils would

tested territory If it had not been for
the early frost. The other reason for
an unusually restricted dispersion Of
movements in 1914 was the dry wealth
er of August and early September.
This prevented the development of
many weevils, and is important in
connection with dispersion, the ,ex,.
tent of which depends largely upon
the volume of weevils present in the
territory from which the flight takes
place. Although the movement of
1914 will not be as extensive as the
movements of some other seasons
there will be continuous spread from
year to year, and the average distance
covered will undoubtedly continue to
be in the neighborhood of fifty miles
each season.
One of the most important recent
discoveries about the boil weevil is
its occurrence on wild cotton-like
plant in Arizona. This plant grows in
mountain canyons and has furnished
food for the weevil for many centu-
ries. 1t has been found from expert
ments performed recently that the
Arizona weevils need only the pres
ence of cotton to transfer their attack
against that plant. The importance
of the discovery lies in the fact that
the Arizona weevil has acquired an
ability to stand extreme arid condi-
tions. 1t is the absence of such pow
err on the part of the form of the
boil weevil which occurs outside of
Arizona that has prevented the inva-
sion of the drier portions of Texas.
In connection with the recent dis
cussiOn Of the necessity of reducing
the production of cotton in the United
States it has been proposed by num-
Der of persons that the time is op-
perfume for the eradication of the
weevil by compelling the abandonment
of cotton for one year at least in all
of the territory which has been reached
by the insect up to the present time.
There are very serious practical diff
culties in the way of this plan. Spe-
cial legislation would have to be en-
acted, and a very large appropriation
would be required to enforce the regu-
lations. Undoubtedly in many locali-
ties there would be strong disinclina-
ton on the part of the planters to
abandon cotton, and strict measures
would be necessary to bring about
general action. Moreover, there is
much volunteer cotton in the South
each year, especially after wild win
ters. Seeds which fall from the bolls
in the fall frequently live through the
winter and are planted Internationally
in the preparation of the ground the
following season. About gins and oil
mills many volunteer plants groras
Where the conditions are favorable
arge numbers of such plants are also

railroads. In this case the plants
spring from seed that are dropped
rom the passing cars. Very thorough
work would have to be done in every
ocality throughout the South to guard
against the breeding of weevils on vol /
lutsc- plants"
