All this I had long known from my reading, and from certain folk tales picked up in New Hampshire; hence when the flood-time rumours began to appear, I could easily guess what imaginative background had evolved them. I took great pains to explain this to my friends, and was correspondingly amused when several contentious souls continued to insist on a possible element of truth in the reports. Such persons tried to point out that the early legends had a significant persistence and uniformity, and that the virtually unexplored nature of the Vermont hills made it unwise to be dogmatic about what might or might not dwell among them; nor could they be silenced by my assurance that all the myths were of a well-known pattern common to most of mankind and determined by early phases of imaginative experience which always produced the same type of delusion.
