“‘You infernal villain,’ I broke out, however, not very loudly, because at the first movement of my lips he clapped his hand on my throat, and the revolver pressed harder, and now at half cock, a hair breadth’s space between me and eternity.

“By some great effort, however, I managed to blurt out in spasmodic whispers, that the mail had burst; had not been robbed, as could be proved by inspection, and that I wanted to ascertain by what authority he came the detective over me in so forcible a manner.

“Laughingly he took from his pocket a scrap of written paper, held it out of reach, but near enough to be legible, whereon was stated that so-and-so was commissioned by so-and-so to investigate the cause of the numerous losses that had recently occurred on the Puntsville mail route, &c.

“‘No use palaverin’, my renowned skinflint; you’ve been caught squarely and fairly in the deed, and you’re booked certain for Sing Sing, or some other institution conducted on the same charitable system, and you won’t get out for a period—​no, not at least till you get the Presidential pardon.’

“The affair was growing more strangely serious than I had anticipated, and still I lay on the cabin floor with the contents of the mail-bag strewn over and around me, the detective keeping rigid surveillance over my every movement, however slight.

“Leaning forward, with his foot he pushed the door partially ajar, pursed up his moustached lips, whistled a bar of some current popular music, and directly footsteps sounded without, and soon another one of the passengers entered the cabin.

“Exchanging a significant look with my captor, he looked around the room with a quick glance, and coming close to my head, dropped down suddenly on his knees, and almost before I was aware of it, had inserted a gag in my mouth, and there I lay, speechless.

“Without losing any time, they seized me by neck and heels and plunged me, without the least effort, into the bunk. Then a heavy cloth, deeply saturated with chloroform, was thrown over my face, and after that, if you except for an instant a confused sound of rumbling machinery and a rushing of waters, I remember nothing.

“When I regained my senses all the cabin was dark, my brain was confused and obfusticated. I managed to get out of the bunk, looked out the narrow window, and saw that surging black water and heavy, threatening, driving thunder-clouds were the only things visible.

“The waves were rising fearfully, the huge white-capped, black-bodied monsters rushed against the boat’s side with thuds that made every timber rattle; the paddle wheels were idly beating to and fro; the wind shrieked through the chains that held the smokeless stack, and the ‘Silver Arrow’ rocked enough to throw nine out of ten fresh-water sailors off their feet. A hundred thoughts sprang up.
