Formula For Treating Potatoea
Dissolve -four ounces Of bichloride
of mercury in a gallon Of warm soft
water Git docs not dissolve readily in
OF cold water. Large amounts may be
mixed by using the same proportions.
Treat the first batch OF potatoes for
and one half hours, and each sue
ceeding batch for fifteen minutes
longer than the others. (This solution
will act on metal, so a wood tank, or
barrel must be used.)
A very satisfactory. method for
treating potatoes is to take two or
three barrels and set them on a box
or some other support high enough to
get q tub under. Bore a hole next to
the bottom of each barrel, and cork it
up. Fill the barrels about half full
OF the solution, then when the barrel
Is filled with the potatoes the solu-

toes have been treated the required

dump potatoes into a box to drain, put
the solution into the barrel and fill
again with the potatoes. Fifty gallons
of the solution will treat thirty or
forty bushels.

Other Diseases.
There are other diseases which
from time to time make inroads on
the potato, which ma have TO be
treated with spraying. AS spraying is
about the only means for checking the
potato bugs and other insects the
whole subject may be treated rather
generally.
For blights and other fungus dis
eases. the Bordeaux mixture is used;
for beetles and other insects paris

most seaily and economically. The
poison may be mixed with the Bor-
deaux and sprayed on at the same
time.
Great Care Should Be Taken In
Spraying.

or the work may be one too late or
too early. Spraying is rather a pre-
v%entive than a cure, and should be
done at the very beginning of the
trouble rather than after it has gained
much Roadway. There is only q wav
of insurins success and that is to
carefully follow directions, to the min
utest detail. These directions cannot
be given here, but may be secured by
writing the Agricultural College, the
Department of Agriculture, or your
County Agent.
There is absolutely not a question
but that spraying is essential in most
cases, especially in checking the potato
bugs. and in many cases willis may be
prevented by using the Bordeaux
mixture.

on spraying are published by the Ex-
tension Department OF the Iowa Agri-
cultural College. and arS worth pre-
