“No; they are nearly all below.”

“We can’t be too careful where so much is at stake,” said Muller, as he uncoiled the ulster which hung over his arm, and disclosed a dark object which he laid upon the deck. One glance at it was enough to cause me to spring to my feet with an exclamation of horror. Luckily they were so engrossed in the matter on hand that neither of them observed me. Had they turned their heads they would infallibly have seen my pale face glaring at them over the pile of boxes.

From the first moment of their conversation a horrible misgiving had come over me. It seemed more than confirmed as I gazed at what lay before me. It was a little square box made of some dark wood, and ribbed with brass. I suppose it was about the size of a cubic foot. It reminded me of a pistol-case, only it was decidedly higher. There was an appendage to it, however, on which my eyes were riveted, and which suggested the pistol itself rather than its receptacle. This was a trigger-like arrangement upon the lid, to which a coil of string was attached. Beside this trigger there was a small square aperture through the wood. The tall man, Flannigan, as his companion called him, applied his eye to this and peered in for several minutes with an expression of intense anxiety upon his face.

“It seems right enough,” he said at last.

“I tried not to shake it,” said his companion.

“Such delicate things heed delicate treatment. Put in some of the needful, Muller.”

The shorter man fumbled in his pocket for some time, and then produced a small paper packet. He opened this, and took out of it half a handful of whitish granules, which he poured down through the hole. A curious clicking noise followed from the inside of the box, and both the men smiled in a satisfied way.

“Nothing much wrong there,” said Flannigan.

“Right as a trivet,” answered his companion.

“Look out! here’s some one coming. Take it down to our berth. It wouldn’t do to have any one suspecting what our game is, or, worse still, have them fumbling with it, and letting it off by mistake.”
