June, and probably feeding until Au-
gust or September. This beetle has
long been known to eat the leaves OF
the grape in Kentucky, Southern Him
DIS and Missouri, but up to the present
time nothing has been known Of the
habits Of the grubs. "a number Of these
beetles were reared in the insectary
and placed on a vine that was kept for
that purpose. "A small portion Of the
vine was sprayed with Paris green, one
ounce to twelve gallons Of water, and
this application was found to kill them.
In the vineyards bisulphide of carbon
was placed in the ground about the
roots Of the vines, about three ounces
to each vine, and after three weeks all
of the worms about the vines where
the application was made We're found
to have died.
Results of Subsofl Flowing
The following letter, giving the re-
suits Of experiments with subsoil plow-5
ing, was recently received by the sec
rotary Of agriculture from Mr. Peter
Youngers, Jr., Of Youngers & Co., Ge-
neva, Neb.:
Having practiced subsol blowing ex-
tensively on our nursery grounds near
Geneva in growing fruit and orna-
mental trees with gratifying results,
we concluded to experiment with grain
and vegetables.
The ground was prepared by subSOil:
blowing in the fall Of 1892, and the
crop of 1893 consisted Of corn and POI
tatoes. Corn that year being only q
very moderate crop in this vicinity
(maximum forty bushels. per acre, and
the average not exceeding twenty bush
els), we harvested a crop of seventy
five bushels per acre from strip of
ground that had been subsoiled. The
potatoe crop was practically a failure
in this vicinity; the result Of our ex-
pertinent was a good crop-about 125
bushels per acre.
This season $500 the crop consists
Of rye, oats, corn and potatoes. Rye
harvested indicates a yield Of thirty
five bushels per acre, while rye in an
adjoining field-the same seed, planting
and harvest, but not subsoiled--will
yield ten bushels per acre.
Oats on land subsol plowed in fall
Of 1893 will yield forty to forty-fye-
bushels per acre; oats on land subsol,
plowed in fall Of 1892 will yield thirty
to thirty-fve bushels per acre; oats Oh
land adjoining, under ordinary cultiva-:
ton, will yield ten to fifteen bushels,
per acre the average crop under the.
adverse conditions that PREVAILED, In
each instance the seed, soil and plant
ing being the same.
The superiority of subsol cultivation
is especially conspicuous in the length
Of straw and stand on the ground.
The results of experiments with this
years corn and potatoes cannot at this
time be determined. With a continue
ton Of the present favorable conditions
we will have the largest yield Of corn
we have ever had. Even under these
favorable conditions the corn on sub
soil plowed ground seems to possess q
special element Of strength that will,
4 in all probability, exert its influence In
demonstrating the value of subscil Gull
! tivation. 81
Remedy for Plant Lice.
/ These troublesome insects cannot be
poisoned, because they lie by suction
and take the sap from the leaves by
n cans Of their sharp beaks, which they
insert deeply in them. They are only
vulnerable by means of some oily liquid
applied to their bodies. The best Of
these is the emulsion made Of soap dis
solved in water and mixed with kero-
sene oil A pound of soap to a quart
of hot water and a quart of the oil are
the prope; proportions. This is thor
oughly shaken in a jar, and when
en- rlsified it is set away to cool, and
one part Of it used with nine parts of
water. This is sprayed on the insects,
and is deadly to all with which it may
come in contact.
