As we passed out of Brattleboro my sense of constraint and foreboding increased, for a vague quality in the hill-crowded countryside with its towering, threatening, close-pressing green and granite slopes hinted at obscure secrets and immemorial survivals which might or might not be hostile to mankind.

It was in this stream, I recalled from newspaper items, that one of the morbid crablike beings had been seen floating after the floods.
