this solution was made by boiling the
lime and sulphur with a small portion
of water over a wood fire for forty
! sulphur solution was use at the rates
of one and a half. one and three

OF his experiments Mr.. Scott says.
"Arsenate of lead at the rate of two
pounds to fifty gallons was used With
the self boiled mixture, the home
boiled solution. and the Bordeaux
mixture. The commercial solution
was used with arsenate Of lead at the
rate of two pounds to fifty gallons
with Paris green at the rate of six
ounces to fifty gallons, and without
any poison. In the Mount jackson or.
chard the trees We're sprayed: First,
as soon as the petals fell; second.
three to four weeks after the petals
fell, and third, nine to ten weeks
after the petals fell. The Fishersville
orchard on account of scab, received
an additional application, which was
made just before the trees bloomed
The Crozet orchard received the same
treatment as the Mount jackson or
chard, and on account of b!tter-rot a
fourth application three to four weeks
after tho third"
Eject of Sprays on Foliage.
One OF the objects OF these expert
rnents,' says Mr.. Scott, was to de-
termine the effect of the several line
sulphur preparations in combination
| with arsenicals on the foliage of diff
ferent varieties. Several times at in
! tervals during the season notes were
| made on the condition OF the foliage
| of the trees in the experimental plats
| The weather was mostly cloudy and
rainy from early spring until about
July l. so that the conditions were IA
| vorable to the development or spray
injury. During the latter half of the
| season. however, practically no rain
| fell.
In every case, except on the Wine
sap. where Paris green was used with
the commercial llme-sulphur solutions
the foliage was badly burned and in
some instances the trees sprayed with
this combination lost half OF their foil.
