How Michigan Fights CurculiO.

THERE is no fruit Of orr Northern
States more delicious than the plum,
none more scarce, none more profitable
To raise. Yet the curculio has nearly
banished plum culture from our cOun-
try. Notwithstanding the rayageS of the
Little Turk" however, several Michi-
gan urcharb-ts secure this crou annual

since one of our alumni, Immediately
upon graduation. engaged TO labor for
an orchardist of Northern Ohio. Some
fine plum trees attracted his attention.
He asked if they raised plumS. "Oh,
no.. was the response. The trees
bloom full every Year. but the plumS all
drop OF" He gained consent to fight
the curculio. and also gained Il large
and profitable crop of this delicious
fruit. The curcuiio h~ibernateS, and if

South Haven. Mich, whose plum or
chard has been immensely profitable,
states that this method saves him three
hundred dollars annually over the old
method of exclusive Earring. Mr.. Dyck-
man uses oak bark. places we small
pieces beneath each tree, on opposite
sides near the trunk. with smooth sur
face down. He employs boys To gather
the insects, and pays them according TO
the number they find. This insures
close examination. The curculioS are
placed in an open bottle. closed by the
thumb of the one who is gathering
them.
Often the character of the orchard
precludes this method. and even when
practiced it needs TO be supplemented,
late in the season. by the Earring or
sheet process. This is not expensive.
and often brings a tremendous profit.
To practice thS we have only TO put n
sheet-a white sheet is best-beneath
the tree and give the limbs a sudden
jar. The little beetles. looking like
dried buds, fall TO the sheet, when they
can be caught and killed. For a few
trees the sheets can be tackled or
Sewed TO a cheap rectangular frame,
with n narrow slit on one side. so that
the trunk of the tree can be brought TO
the center Of the sheets surface. With
but a few trees, two persons can carry
this sheeted frame from tree 10 tree.
In large orchards it a be placed on
one or two wheels, where n person
can easily MANIPULATE it. The Mallet

they may not be injured. A sudden

the success in catching the beetles.
Let all remember that these little

Not thinking this profitable, he began
