They were all silent for a long while. As it got to be flood-tide, and the water came nearer to them, noises on the river became more frequent, and they listened more. To the turning of steam-paddles, to the clinking of iron chain, to the creaking of blocks, to the measured working of oars, to the occasional violent barking of some passing dog on shipboard, who seemed to scent them lying in their hiding-place. The night was not so dark but that, besides the lights at bows and mastheads gliding to and fro, they could discern some shadowy bulk attached; and now and then a ghostly lighter with a large dark sail, like a warning arm, would start up very near them, pass on, and vanish. ~ Our Mutual Friend
