The Voodoo Gold Trail

It was on a tropic sea, and night, that I heard a little scrap of a tale that had in it that which was destined to preserve my life. The waning moon had not yet risen; the stars were all out, the Milky Way more than commonly near. The schooner's sails were barely drawing, and flapped idly at times. I leaned on the rail, listening to the purling of the sea against the vessel's side, and watching the phosphorescence where the water broke. The bell had just sounded a double stroke—two bells. Near by, the taciturn black fellow—who was our guide, and who alone (as shall appear) knew our course and destination—was in talk with Rufe, our black cook.
Heretofore, this man—black he was, but having hair straight as an Indian's—had been steadfastly mum on the subject of his past; this manifestly being but part and parcel of his policy to avoid any hint of the place to which he was piloting us. But now, I gathered, he was reciting to Rufe an episode set in this far away land to the south; and I cocked my ear. He was telling of something that had happened in his grandfather's experience, who, as he said, was in the service of the king of that land. It was one day when this king was set upon by his enemies, who came thundering on the doors; and the king employed the narrator's grandfather to assist him in his escape. The king collected his jewels and much gold which he put in a bag, and set it on the back of his servant. Then he led the way to a dungeon in the palace. Set in the thick rock wall of this dark cell was a shrine, a carved Calvary—Christ on the cross and figures at the foot.
The king, the black narrator was saying, horrify my gran'father, when he put his hand right on the Virgin, and pull that piece out. Then the sacrarium swing open, and there is one big hole, and the king push my gran'father through, and come after.
And he went on to tell how the king had led on, groping down the steps of this secret passage, and presently out into the forest; and how they two finally came to a fortress, and found safety.
