Look where you're stepping.

We can't show any lights, and it's dark as--" But, even as he spoke, like a flash of powder, as swiftly as one throws an electric switch, as blindingly as a train leaps from the tunnel into the glaring sun, the darkness vanished and the tug was swept by the fierce, blatant radiance of a search-light.
It was met by shrieks from two hundred throats, by screams, oaths, prayers, by the sharp jangling of bells, by the blind rush of many men scurrying like rats for a hole to hide in, by the ringing orders of one man.

Above the tumult this one voice rose like the warning strokes of a fire-gong, and looking up to the pilot-house from whence the voice came, David saw the barkeeper still in his shirt-sleeves and with his derby hat pushed back behind his ears, with one hand clutching the telegraph to the engine-room, with the other holding the spoke of the wheel.
David felt the tug, like a hunter taking a fence, rise in a great leap.
Her bow sank and rose, tossing the water from her in black, oily waves, the smoke poured from her funnel, from below her engines sobbed and quivered, and like a hound freed from a leash she raced for the open sea.

But swiftly as she fled, as a thief is held in the circle of a policeman's bull's-eye, the shaft of light followed and exposed her and held her in its grip.

The youth in the golf cap was clutching David by the arm.
