f ly that a large part of this injury can be prevented by
the use of arsenical poisons applied with spraying
pumps.
‘’‘i In Bulletin No. att), of this Station, Prof. Garman,
», _ Entoniologist, has treated of this with several other
l ~ insect pests, but unfortunately this bulletin is now out
Era ` of print. I therefore quote the following from his sug- Y `
' ’ N . . . . l ·
, i§__*,sss»; ~ gestions for combating this insect : l
" hi {
2 A "Most of the fruit ordinarily lost from eodling-moth depredations ;
i `,· can be saved by spraying the trees in spring with London purple or  
li Paris green in water, employing for the purpose a force pump and l
  { spray nozzle connected with a barrel holding the mixture, and using
, t one pound of either poison to from 160 to 200 gallons of water. The
T spraying must be done immediately after the petals fall from the
Q blossoms, and this may be followed by a second application in a week
l or ten days. On no account should the spraying be done before the
5 petals have fallen; and it should not be delayed long after they are
. ` T down, for the reason that it is not possible to reach the worms with
_ \_ any application after they have entered the fruit. With apump
.. — » such as is made for the purpose by the Nixvn Nozzle and Machine
\ :` Company, of Dayton, Ohio, an apple tree of large size can be sprayed
X` in from one to two minutes?
§` i; As a safeguard against the larvze of a second brood ‘
` Y
q   . of moths, Prot`. Garman suggests that apple trees be
gf ` sprayed again with Paris green not earlier than July lst.
~ The most common and one of the simplest methods
, of treating the tent caterpillar, and the plan successfully
  followed by many of our correspondents, is that of
’l' destroying the young caterpillars, in the morning or at
  night, while within their nests in the tree, either by hand g
or by means of a torch at the end of a pole. The latter
l method is somewhat objectionable, as in the effort to
’ . eradicate the insect pest, the branch is liable to be in-
jured or even killed by the torch. A careful examination
` of an apple orchard in winter will usually reveal the
eggs of this insect glued on a band around the smaller
twigs, and if these are cut off and burned, much trouble
