There was a shout of warning as the bows, caught by the current, began to swing out into the stream, and the end of the gangplank slipped along the edge of the wharf.

It threatened to fall into the river, and the girl was not yet on board.

Blake leaped upon the plank.

Seizing her shoulder, he drove her forward until a seaman, reaching out, drew her safe on deck.

Then the paddles splashed and as the boat forged out into the stream, the girl turned and thanked Blake.
He could not see her clearly, for an overarching deck cast a shadow on her face.
"Glad to have been of assistance; but I don't think you could have fallen in," he said.
