Mass.
Ipswich. - over a broad expansion of level dry sand
  then climbed the slope of a high hill and
  finally lost itself in a great expansion of beach 
  grass bordering the beach.
    Another track, which was seen in many 
  places along the margins of the fresh water
  ponds, pr[?]d both of us for some time. Indeed
  it is doubtful is we should have guessed its
  origin at all had we not finally come
  upon the creature itself at the end of his
  trail crouched on the side of a perfectly bare
  hill on the warm sand basking in the
  sunshine. It was a leopard frog!  The track
  consisted of two foot prints (those of the
  hind feet) placed side by side at intervals
  of from one to three feet. The claw muscles
  were conspicuous but the sand was too loose 
  to take the impression of the large, webbed
  feet clearly and up to the moment of 
  finding the animal we had not thought
  of anything than a mammal of some
  unusual kind.
   On the dry sand above tide mark I saw some
  perfectly clear foot prints of a three-toed bird
  which, had the date been August or September
  instead of March I should have [?]
  [?] a Black bellied Plover. As it is
  I do not see how these tracks, which are
  as far as I know unmistakable, could have
  been those of any other species.
    I forgot to mention that we started a pair of Black
  Ducks from the fresh pond in the sand hills by the rim.
