Vine Mildew and Insects.

In one Of our earlier Rumbers our
valued correspondent DIR. Uhler, gave
us translation from the French of
Raspails' experiment in watering plants
with solution of aloes, in order to
render the plants themselves distasteful
to insects Experiments VIC believe

curculio is concerned, and found to be
unavailing but when we consider that
not only is the fruit of a plant composed
of more elaborated form of the sap,
in which we might naturally look for

in this point alone less likely to be
effective than when employed externlly
to keep the plants clear ofinsects,-we

nauseous thing whether externally or
internally applied is likely to be proof

tanned fact that vegetation, as well as
animal substances do. not entirely
change the nature of the combinations
they absorb into their systems by the
process ofnutrition. The flavor ofthe
turnip and garlic can be tasted in the
milk of the COW, and as some trace of
coffee and tobacco have been found in
the flesh of the subjects who have been
partial in their life time-time to the

early and monstrous maturity, have a
well known disagreeable taste of the

formed by grass, which owing to the
accident of having an abundant supply
of rank manure cast in its immediate
vicinity, has become so impFegnated
with disagreeable matter that cattle
will starve rather than touch them
This all goes to show. that the prin-
ciple DIR. Uhler presented for our rea

French are still pursuing their investi-
cations, and widening the field of in

Journal, is the report of paper by NJ
Mereieal, read before the Academy of
Natural sciences, at Paris detailing an
/ appliea tien Of the principle to the pre-
yention Divine Mildew. "He selected
a number of stocks Of diseased Vines,
which the pregious year had been so
seriously attacked by the 0idinm that
not Grape could be gathered. He
divided them into two equal groups
The one he submitted to treatment,
and the other1e left for the sake of com
parisou. In the beginning Of August
the Oidium. began to appear on both
groups. On the 10th he submitted tile
first group to the following treatment
he removed the earth aroundthe stems
of the Vines a distance of about foot,
and of a Gepth to lay bare the small
rootlets. Into each excavation thus
made he put large handful Of flowers
of sulphur, heaping it up around The
stems Phis being done he replaced
the earth and watched the Vines daily.
On the Goth of September the WINS
of the &rst group were in excellent
condition, and the Grapes presented a
fine appearance. The mycelium (fun-
| gus) had not disappe from the ber-
ries which were attaked at the time the
sulphur was applied, but they were nos
farther diseased, and he had every rea-
son to believe that they would ceme to
perfection lie particularly observed
that none of the o-hcr berries became
diseased The second group was in a
pitable condition. The Oidium had
made rapid progress, and there APP
peared every reason to fear Il at not a
single Grape would be saved

is a satisfactory solution Of the Vine
