The blue-light hissed and flared up when the match was applied, shedding its livid glare upon the weather-stained faces of the seamen.

"Stand by the fore-braces!" called the officer; and the seamen rushed forward to execute the order.

The next instant I found myself spinning through the air, and then plunging deep down into the bosom of the tranquil sea. I was in my element now, though it was rather too much element; but I struck out, as soon as I rose to the surface, for the blue-light. I shouted for help; but the great steamer seemed to be hard of hearing, and went on her way as though nothing had happened. I swam as I had never swum before, and reached the barrel just as the despatch boat stopped her wheels to pick it up.

"Steamer ahoy!" I shouted
