Gypsy Moth conditions

  Prescott's Pines. Badly infected in spots but safe, I think,
for another year especially if the few deciduous trees be removed.
  Birch Island Woods. - Almost completely defoliated yet
largely free from moths or living larvae. Laying females
were numerous in a few places, however. It looks as if
the woods might survive another year although many trees are dead.
  Birch Field. - Very few male moths flying and almost
no laying females seen except along the north edge of the
lot, next Lawrence's, where the line of tall trees is badly
infected and along the south edge next the run where there
is lighter, yet rather serious, infection.
  Pulpit Rock Woods. Nearly clean except for a few white
oaks just to the westward of the rock and others on the ledgy
slope towards the low pasture which are rather badly
infested and also injured by repeated stripping which has
caused more or less of the upper branches to die.
