In a land where nearly all the solid substance is rock -- not stone, mind you -- The Rock held a peculiar position. It dominated the landscape and the imagination of Silver Gap, and the superstition as well. It was a huge, greenish-white mass, a mile to the east of Thunder Peak, and over its smooth face innumerable waterfalls trickled and shone. With this colour and motion, like a mighty Artist, the wind and light played, forming pictures that needed little fancy to discern.

At times cities would be delicately outlined with towers and roofs rising loftily; then again one might see a deep wood with a road winding far and away, luring home-tied feet to wander. And sometimes -- not often, to be sure -- the Ship would ride at anchor as on a painted sea.

The Ship boded no good to Silver Gap as any one could tell. It had brought the plague and the flood; it brought bad crops and raids on hidden stills; it waited until its evil cargo had done its worst and then it sailed away in the night, bearing its pitiful load of dead, or its burden of fear and hate. Surely there was good and sufficient reason for dreading the appearance of The Ship, and on a certain autumn morning it appeared and soon after the two women, unknown to each other, came to Ridge House and this story began.
