I jumped to the conclusion that the Islander had struck on one of the shoals I had noticed on the chart, and the heavy sea was pounding her on the bottom. It could be only a question of time when she would knock a hole in her bottom and go to pieces. Washburn was wide awake as soon as he heard the gun, and giving him the wheel, I proceeded to examine the chart.

According to the dead-reckoning we ought to be a little to the southward of French Shoal. While I was satisfying myself in regard to our position, another gun sounded over the troubled sea.

"That can't be the Islander's gun," said Washburn. "She has nothing on board but a little yacht gun, and the piece we heard is a six, if not a twelve pounder."

"I think you are right, Bob. The sound came from the leeward. I have no doubt it is some vessel in distress; and we must do something for her. Call all hands," I continued, as I took the wheel, and headed the Sylvania due west by the compass.

Though it was not foggy, the air was thick, and I could see nothing ahead. We had a very strong wind on our port quarter, and it was extremely dangerous to approach the reefs from the windward. In a moment all hands were on deck, except Moses Brickland, who was required to take the engine whenever all hands were called on an emergency. I directed Hop Tossford to take the wheel, and keep her due west. I asked the mate to fire our little yacht gun, in answer to the signals we had heard. The moment the report sounded through the vessel I heard Mrs. Shepard scream.

I told the chief engineer to give the steamer about half speed, and hastened into the cabin to satisfy the passengers that nothing had happened to us, and explain what we were doing. Mrs. Shepard assured us that we should all be lost; but I told her we would be extremely careful.

I asked my father, Colonel Shepard, and Owen to come on deck, leaving Mr. Tiffany and Gus Shepard to take charge of the ladies. I explained the situation to them, and while we were talking about it another gun was heard to leeward. It sounded heavier and nearer than before, and I was sure the signal was not given by the Islander.

"It is plain enough that a vessel has gone ashore on one of these reefs," I said. "I can see nothing ahead, but the gun sounds in this direction."

Before the words were fairly out of my mouth, a sky rocket flashed up directly over our bow. We had rockets on board, and I directed Ben to discharge one of them. It was followed by another from the vessel in distress. Then some Bengola lights were fired, and they illuminated the sea for a mile at least around her. Buck Lingley was sounding, and reporting no bottom. I told the engineer to give her more steam, for I feared the people on the unfortunate vessel might be drowning, and a minute might save a life, if not more. As long as the bright Bengola light burned, I kept the steamer going at full speed. Most of the dangerous reefs were marked by beacons, or at least the outer range of the reef was so marked.

The sea was very heavy, and Buck Lingley still reported no bottom. He used a hand lead, which measures twenty fathoms of depth. The Bengola light soon burned out, and I rang the speed-bell. This reduced our rate one half. But it seemed to me that we were going altogether too fast, as the strong south-east gale was driving us towards the reefs. I rang the gong, and the vessel stopped.
