Gypsy Moth conditions

Blakemore Ridge. - The "wilt' raged here, also; nevertheless
I found plenty of females laying their eggs on the trunks
of the oaks and multitudes of males hovering about them.
These woods will surely be defoliated next year unless
vigorous measures are taken to protect them.
  Holden's Hill. - High colony of laying females, hard to 
deal with because the trees are so tall and slender. The
"wilt" has evidently done little good here.
  Davis Hill. - Conditions desperate. Immense & thriving colony 
of apparently healthy insects. Upper branches of the giant pines
white beneath with clusters of laying female moths and the
males swarming everywhere. The pines evidently much
injured many of them being half stripped and some almost
wholly bare and apparently dying. Most of the oaks completely
stripped and scores of them already dead. As far as I
can see all the trees are doomed to perish next year
unless protected at great expense.
