“She’s right on us!” cried Harry, grinding frantically at the crank. Gerald, standing at the wheel, peering forward, worked desperately at the whistle pull and jammed a lever over. _The Dart_ lost headway, slowed, stopped. The loud throb of the steamer’s screw seemed all about them. Uncertainly, Gerald started _The Dart_ forward again, turning her nose to starboard. Then, as another hoarse bellow came to them, he stopped the launch as suddenly and pulled the lever to reverse. The launch began backing away, circling slowly, to an accompaniment of hysterical shrieks of the whistle and agonized groans of the fog-horn.
