IL was noted that the plants Of cab
bage, radishes, etc, grown In the cold
frame are scarcely injured by the nca-
beetle None Of the applications used
for the ilea-beetle had any perceplible
effect IN preventing injuries from the
radish-ny. but satisfactory results we're
gained by the use Of coal ashes.
The only application that appeared
TO prevent the injuries Of the striped
cucumber beetle was Paris green mixed
with water, at the rate Of half a tea
spoonful TO two gallons, and the MKT
uro applied to both sides Of the leaves.

II has been claimed that the Buhach
powder will kin the potato beetle when
applied TO it in the open air With q
view to verifying this statement we
thoroughly busted several beetles while
on the plants with the pure powder on
July 25, and after they had fallen to
the ground placed them in bottle,
over the top Of which we tied bit Of
mosquito netting. The beetles soon re-
covered their activity and exhibited no |
Inconvenience as the result Of the APP |

placed in the bottle in order that the |
starvation Of the beetles might not con

of the poison Later observations,
however, showed that this precaution |
was entirel, unnecessary, foron August

the beetles were still alive. These app I
piled themselves with their accustomed I
yigor to potato leaves inserted into the /
bottle, though they had tasted during /
a full month.

beneficial in rotarding, il not wholly |
preventing, the work Of The borer. The
coal tar application, it is thought is
probably more permanent 10 It's action

sion. 1t is assured that it does not de-
stroy the insects, but only repels them,
while the other two appear to poison
