"Mr. Tolman, could you tell the man if you should see him again?" asked Dave.

"Could I? yes, indeed."

"How did he look? What was the colour of his hair, his eyes; and how was he dressed?"

"Now--you will think it strange--I can't tell any of his features or what clothes he wore, and yet if I should see him I don't believe I should miss him. I could tell him by the look of his eyes--a look that somehow appealed to me--a look without hope. Often when at night I see the froth on the bar in the moonlight, I seem to hear that man calling to me, and I take it as a sign that he is still in a worse fix than if on the bar. It is an awful curse, rum, and I am a sworn foe to it."

Here the light-keeper placed the sandal-wood box again on its shelf, and Dave turned to look out of the window near the kitchen table.

"See here, Mr. Tolman; what's that?"

"Where?"

"Floating and curling over that point!"

"Can't you guess?"

"Looks like fog! Yes, I can see now plainly. Oh, can we start up the fog-signal?"
