Depredations of insect pests

various kinds on practically all unsprayed foliage excepting that of 
pines and maples. Brown-tail larvae were numerous, Gypsy ones
exceptionally so, Tent caterpillars far more abundant than they have 
ever been known to be before within my experience and Forest Tent
caterpillars about as countless and destructive as any of the rest. 
By one or another of these pests - or by all four of them combined -
the greater part of our woodland had been striped so
completely of foliage by the end of June that the trees were
almost as bare as in mid winter. Davis Hill and Birch
Field seemed hopelessly ruined when I saw them last,
even the white pines being mostly denuded. Our spraying
was everywhere perfectly effective but it cost a lot of money 
(over $700) & lots of my time & that of my farm hands.

Cats

  Lawrence's cats, to the number of half a dozen or more, overran
the farm throughout the entire season but if they caught any birds I failed
to detect evidence of such depredations. They exterminated the chipmunks
almost completely & thinned the numbers of Red Squirrels very appreciably.
