Up the River by Oliver Optic

The Sylvania was close-hauled, and I gave out the course south south-east. This was the navigation to take the steamer around the peninsula into the Gulf of Mexico, though we intended to put in at Key West, in order to see the place. Washburn noted the departure on the log slate in the pilot-house, and, as it was necessary for us to run by our dead reckoning, the log was heaved every hour. In a short time we were buried in the fog, and kept our steam-whistle going at the proper intervals.

The young ladies soon deserted the pilot-house, for we were obliged to keep the front windows open, and the air was cold and moist. Owen left with them, and my father and Colonel Shepard soon took their places. The owner of the Islander was still too much excited to keep still. He tried to see through the fog; but he might as well have attempted to look through a rocky hill.
