The McKay Disc Plow and Subsoiler
plows the land and subsoils it at the same
time. The plow runs in a straight line
with the direction of the horses or tractor pulling.

Sbewlng Egg.JPUncture of Boll Weevil and Flaring ot
a Square
there is no perceptible difference be
tween males and females, their size
and generarexternal appearance be
ing quite similar. Some have inferred
that the larger weevils were males
and the smaller females, or vice
versa, -but these assumptions are in
correct, since size is dependent upon
the size of the square or boll in which
the egg is laid and thus upon the
food supply of the young, rather than
upon :sex.
Identifying the Weevil. Entomolo
gists have found it practically impos
sible to describe
the boll weevil so
that the average
cotton grower, un
aided by a glass,
can identify it with
any degree of cer

about 200 different
