the consensus of opinion by majority of
those who have used both methods, that
when the dust formulas are perfected
they will supersede the liquid.
The danger of burning the foliage or
rusting the fruit is entirely with the liz
uid. The problem now is the proper ratio
for best results, and practical tests in
the orchard alone will solve the problem.
1t has been fully demonstrated that
arsenites in dry form can be used at any
required strength on any kind of foliage
without injury to same. The simplicity,
ease of application and the total absence
of dangerous elements in the dust process
should appeal strongly to the practical
grower.
We must take into consideration that
the dust process is in its infancy, as it
were, having had no help from the gov
eminent or state experiment stations as
a rule Its reputation stands wholly on
practical work in the orchard as COM
pared with the liquid process, which has
been perfected and improved so far as
ability, experimenting and money can
perfect it, and today stands on its merits
as such. When the dust process receives
the recognition that its merit entities it
to, the old liquid system, like many others,
will be relegated to the past.
1t was developed at the ST. Louis expo
stion, through representatives of the
horticultural interests of Germany and
France, that those countries were far
ahead OF the United States in the use of
dust fungicides and insecticides, and
where in use they have to great extent
superseded the liquid process. Especially
is this true in their vineyards.
We learn that Mr.. Brant, president of
the orange and lemon growers associa-
tion of Southern California, has used the
dust formula exclusively for the last three
years-his neighbors using the liquid
and his orchards have been as free of in
sects as theirs. Moreover the cost to him
has been only about one-third as much !
as they have expended for no better pro-
lection.
Mr. Brown, secretary of the Yakima |
union in the state of Wash
ington, claims he can, with dust alone,
do more and better work than three men
and team can with the liquid process,
having learned this from practical eXpe-
rience. He finds it much more effective I
for the codling moth. One pound of
Paris green to 20 pounds of lime is his I
He also finds that dust adj /.

The animal world abhors dust in any
form. l have found by experience that
dust is far ahead of liquid for checking |
the ravages of the Colorado beetle on po-

the formula. 1t adds to the yield and /
there is no danger of burning the foliage. |
Dust will lessen the depredations of |
the curculio on the plum and peach more
effectively than liquid, which is verified |
by growers who have used both formulas. /.
As this is an age of progress, we may
ook forward to the perfecting of the dust |
formulas at no far distant day
In this, like all other deep subjects, he /
who would seek for pearls must dive be
