ton and destroying all plants which
have not already been destroyed. and
the work is done thoroughly, the
morning glories should be fully Grad
icatod. II Is probable that summer
following and grazing with sheep for
an entire summer would be advisable
as preliminary treatment. The next
year follow with corn and by hand
wedding the eradication should be
very complete.
Prof. T. ]. Durrill, University OF IL
linois You ask how may morning
glorles in corn field be exterminat-
ed. Now we have quite number OF
different kinds of morning glories
which might occur in corn fields In
our country. Only one of these is ex-
ceedingly difficult to eradicate. This
has a slender root with small leaves
and runs close over the surface of the
ground. Sometimes 1t may grow
throughout the season without flower
ing, at other times small white tu-
bular flower is produced in more or
less abundance. This Is colvolvulus
arvensis, a plant introduced from Eu-
rope. 1t is one of the hardest weeds
know Of to get rid of. 1t thrives best
in rich soil. 1t is not so injurious
to crops as many other weeds, but Is
exceedingly persistent. After a con-
siderable experience with it and nu-
merous experiments in determination,
nothing better has been found than
very thorough and very frequently re-
peated surface cultivation, with teams
or by hand In a corn field it would
be necessary to supplement the Guilt
vator with a hoe. There Is no use in
trying to dig the plant out of the soil;
all that is necessary is to remove, at
least once week, every vestige of the
plant above the surface. This treat
ment will exterminate 1t If persisted
in. The other morning glories, though
difficult to get rid of, are comparative
ly easy to manage. Such cultivation
as the corn ought to have is pretty
sure to exterminate them.
Prof. Cranefeld, Wisconsin Expert
ment Station: The name morning
glory as commonly applied may mean
any one of three distinct weeds, viz:
An annual plant Ipomoea purpurea;
two perennial plants: Convolvulus
carvensis and Convolvulus cepium.
The first named is not very common
weed in Wisconsin and may be Grad
icated by any thorough system of Gull
tivation that will prevent the plants
from forming seeds. Carvensis, or
bindweed, is probably the most per-
nicious of the three mentioned: 1t Is
propagated by deep growing peren-
NAL root-stocks, as well as by SEEDS,
and consequently the ordinary meth
DDS of cultivation serve as excellent
aids in propagating 1t by scattering
the root-stocks. These are closely set
with buds, as many as six growing on
piece two inches in length, and each
bud capable Of producing plant. 1t
will live in sod land but Will not
spread there to any great extent.
Remedies: Cultivation, so thorough
that no shoots are allowed to appear
above ground would probably starve
out the roots in two seasons, and pos
sibly in one. This may be done by
summer following the land aided by
the frequent use of spring tooth har-
row. Mulching the infested ground
very heavily will also accomplish it,
but the mulch needs to be about two
feet thick and the spot carefully
watched else the weed will creep out
beyond the mulch. The last named
weed, c. cepium, is not commonly as
dangerous as to the others; it thrfves
mainly m low land
