The use Of alkaline fertilizers. such

that these fertilizers are used in too
small quantities. Not less than 5000
pounds TO the acre should be used to
produce the desired effect-one-half APP
piled In December and the other in
May. The application OF vermlcides
has been found unsatisfactory and
usually kills the host plant in the pro-
cess. Such results have, however,
probably developed from too heroic
effort to eradicate the disease at once.
In view OF the recent developments
with respect to the fertillzinR effect of
carbon bisulphide II appears quite
PROBABLE that by inserting weaker So
lutions into the ground as Is usually
done for the treatment Of subterrancan
insects. great benefit will be derived

by this method. however, two or
three applications would need to be

treatment might need to be extended
over period OF two years instead of
two months. This ls probably better

with this duplicate discussion OF the
various host plants susceptible to the
root rot and root gan diseases and the
treatment In each case enabling the in
diyidual either to guard against the
cultivation Of the susceptible host
plants or beginning the eradication of
the diseases, II certainly is utter folly
for anyone to suffer loss, and In the
future should be left to suffer and pay
the penalty OF his bad management.
With regard to root tumor II must
be stated that the scientific researches
during the past year so far as known
have developed no new facts further
tributlon 10 this society No specific
germ has been discovered and no adj
ditional remedial measures. No direct
experiments have been made to test
the possibility OF the infection OF
healthy stocks by buds from diseased
trees, and the best that can be stated
on that point is that all the evidence
points in that direction and that as a
matter of ordinary business we should
avoid using buds of diseased trees in
the propagation Of our nursery stock.
If this is avoided II matters little
whether the disease Is caused by n
fungus or u horseny, because we go
out Of dangers way.
There Is no danger, however, I'm the
transfer Of buds taken from trees af-
fected with the root gall parasite since
that intruder Is II small animal which
is confined to the roots of the trees and
| does not enter the circulation Of the
sap. The same applies to the root rot
disease except that the parasite In this
case is a fungus.
