Thoreau writes in his journal:
Spoke to Skinner about that wildcat which he says lie heard a month ago in Ebby Hubbard’s woods. He was going down to Walden in the evening, to see if geese had not settled in it (with a companion), when they heard this sound, which his companion at first thought it made by a coon, but S. said no, it was a wildcat. He says he has heard them often in the Adirondack region, where he has purchased furs . . .
