[June 18, 1910]

  A hot, sultry day, calm & for the most part clear but with
clouds gathering in late afternoon and thunder showers hovering
about, some coming near us.
  Most of the numerous birds which are nesting close
about our house are having exceptionally good success in
hatching and rearing their young. The Crows, Jays and Red
Squirrels are not molesting them at all this season perhaps
because the larvae of the brown tailed & gypsy moths
supply them with abundant food in the woods. I have
seen them only occasionally along the wood edges of the
Farm and not once near any of the buildings. A
Red Squirrel appeared in the elms in the door yard yesterday
& spent an hour there. I thought at first he was nest
hunting for he searched every branch from base to tip with the
closest attention. But he caused no alarm among the Orioles,
Robins, Vireos etc. and after getting out the gun I put it away
again when I saw him repeatedly take from the underside of a
leaf & eat what I am nearly sure was a live caterpillar.
