"Another scream!"

I threw down the fork and rushed to the door, followed by my hostess. When I opened it I heard a sound of incoherent lamentation.

"My mother! Help! For God's sake! She is drowning!"

In two jumps I leaped over the rampart between me and the wharf, and made out the figure of a woman waving her arms convulsively and uttering piteous screams.

I saw what had happened, and, running to her, I asked:

"Who has fallen in?"

"My mother! Save her! Save her!"

"Where?"

"Here!"

And she pointed out the narrow space in the water between a lighter and the wharf.
