while, then slackened steam
and went cautiously gliding toward the spark. Presently Mr. Thornburg
exclaimed--

'Hello, the buoy-lantern's out!'

He stopped the engines. A moment or two later he said--

'Why, there it is again!'

So he came ahead on the engines once more, and rang for the leads.
Gradually the water shoaled up, and then began to deepen again! Mr.
Thornburg muttered--

'Well, I don't understand this. I believe that buoy has drifted off the
reef. Seems to be a little too far to the left. No matter, it is safest
to run over it anyhow.'

So, in that solid world of darkness we went creeping down on the light.
Just as our bows were in the act of plowing over it, Mr. Thornburg
seized the bell-ropes, rang a startling peal, and exclaimed--

'My soul, it's the sounding-boat!'

A sudden chorus of wild alarms burst out far below--a pause--and then
the sound of grinding and crashing followed. Mr. Thornburg exclaimed--

'There! the paddle-wheel has ground the sounding-boat to lucifer
matches! Run! See who is killed!'

I was on the main deck in the twinkling of an eye. My chief and the
third mate and nearly all the men were safe. They had discovered their
danger when it was too late to pull out of the way; then, when the great
guards overshadowed them a moment later, they were prepared and knew
what to do; at my chiefs order they sprang at the right instant, seized
the guard, and were hauled aboard. The next moment the sounding-yawl
swept aft to the wheel and was struck and splintered to atoms. Two of
the men and the cub Tom, were missing--a fact which spread like wildfire
over the boat. The passengers came flocking to the forward gangway,
ladies and all, anxious-eyed, white-faced, and talked in awed voices of
the dreadful thing. And often and again I heard them say, 'Poor fellows!
poor boy, poor boy!'

By this time the boat's yawl was manned and away, to search for the
missing. Now a faint call was heard, off to the left. The yawl had
disappeared in the other direction. Half the people rushed to one side
to encourage the swimmer with their shouts; the other half rushed the
other way to shriek to the yawl to turn about. By the callings, the
swimmer was approaching, but some said the sound showed failing
strength. The crowd massed themselves against the boiler-deck railings,
leaning over and staring into the gloom; and every faint and fainter cry
wrung from them such words as, 'Ah, poor fellow,
