The white man, turning his back upon the setting sun, looked along the empty and broad expanse of the sea-reach. For the last three miles of its course the wandering, hesitating river, as if enticed irresistibly by the freedom of an open horizon, flows straight into the sea, flows straight to the east-to the east that harbours both light and darkness. Astern of the boat the repeated call of some bird, a cry discordant and feeble, skipped along over the smooth water and lost itself, before it could reach the other shore, in the breathless silence of the world.
