Catskill Mountains had always been haunted by strange beings. It was affirmed that the great Hendrick Hudson, the first discoverer of the river and country, kept a kind of vigil there every twenty years, with his crew of the Half-moon ; being permitted in this way to revisit the scenes of his enter prise, and keep a guardian eye upon the river and the great city called by his name. His father had once seen them in their old Dutch dresses playing at ninepins in a hollow of the mountain; and he himself had heard, one summer afternoon, the sound of their balls, like distant peals of thunder.
