bulletins have been sent out
by the state plant board OF Florida
detailing a; length the Improved
method Of controlling the boil wee
VIZ as evolved by Or. George y.
Smith. assistant entomo,oglst OF the
board. and announced Saturday night
by Wiimon Newell. director.
While expressing confidence tina,
Florida growers OF upland cotton by
following the new method are as
surcd OF at least go per cent OF a
normal crop, Or. Newell points on,
at tn" outse, that DR.. Smiths cxneri-
in"nts were made under Florida con :
ditions, and the method evolved is
ADAPTED to this State. but there
seems to tic no reason "on thcorcti-
