A TIMELY RESCUE.

It was in the month of February, 1831, a bright moonlight night, and extremely cold, that the little brig I commanded lay quietly at her anchors inside the bay.

We had had a hard time of it, beating about for eleven days, with cutting north-easters blowing, and snow and sleet falling for the greater part of the time.

When at length we made the port, all hands were almost exhausted, and we could not have held out two days longer without relief.

“A bitter cold night, Mr. Larkin,” I said to my mate, as I tarried for a moment on deck to finish my pipe.  “The tide is running out swift and strong; it will be well to keep a sharp look-out for this floating ice, Mr. Larkin.”

“Ay, ay, sir,” answered the mate, and I went below.

Two hours afterwards I was aroused from a sound sleep by the vigilant officer.  “Excuse me for disturbing you, captain,” said he, as he detected an expression of vexation on my face; “but I wish you would turn out, and come on deck as soon as possible.”

“Why—­what’s the matter, Mr. Larkin?”

“Why, sir, I have been watching a cake of ice that swept by at a little distance a moment ago; I saw something black upon it—­something that I thought moved.”

We were on deck before either spoke another word.  The mate pointed out, with no little difficulty, the cake of ice floating off to leeward, and its white, glittering surface was broken by a black spot.

“Get me a spy-glass, Mr. Larkin—­the moon will be out of that cloud in a moment, and then we can see distinctly.”  I kept my eye on the receding mass of ice, while the moon was slowly working its way through a heavy bank of clouds.

The mate stood by with a spy-glass.  When the full light fell at last upon the water, I put the glass to my eye.  One glance was enough..
