"A little thing like a clearance will not keep Bob Carew in port," interposed Captain Dabney.

"No, I suppose not," replied Little Billy, his face sobering. "He is on our heels now, I dare say. However, we have had the satisfaction of putting a good one over on him."

"But—but what—" stammered Martin, his eyes still upon the envelope; the others' reference were Greek to him.

"So friend Blake is puzzled!" exclaimed the hunchback, his light humor returned. "Are you not beginning to see light, Blake? Observe—" he tapped the skin with a finger—"this cryptic skin contains the secret of Fire Mountain. Ichi, the wily one, abstracts it from its discoverers and rightful owners and carries it to that fine legal rascal who employed you; fine legal rascal gives it to clerk to deliver to Wild Bob Carew. Wild Bob Carew has rakish schooner ready to scoot for loot, but needs code translation, and latitude and longitude; friend Blake carries code in pocket, friend Mate carries position in head—so, there is plot and counterplot; gumshoeing and shanghaiing. You, my friend, at the center of one storm circle. Devious and devilish machinations assail you—at first with failure, for the mate lost her wits, and the boatswain lost his balance. But Little Billy Corcoran, King of Legerdemain, succeeds. With his prattling tongue and dexterous fingers he effects the substitution, and the lost is regained."

Little Billy finished triumphantly, and beamed at Martin's blank face.

"Substitution!" exclaimed Martin.

"Yes. Must I place a tack upon your head, and smite it with a hammer, in order to drive the point home? Do you not comprehend? Little Billy sat upon a fire hydrant and very carefully picked a young gentleman's pocket."

"Why, then it was you placed the envelope containing the blank paper—" commenced Martin.

"Exactly. Your intuition is remarkable," stated the hunchback. "But—please—do not look so shocked. I assure you I do not commonly pick young gentlemen's pockets. It is a vulgar pastime, and I am an accomplished villain. Why, once upon a time, I wrote an epic poem. What mere larceny can compare with that fell deed! Besides, this particular outrage upon the sanctity of your overcoat was not without justification. Observe: Ichi, the beast, picks Little Billy's pocket, and the way to Fire Mountain is lost; Little Billy picks Mr. Blake's pocket, and the way to Fire Mountain is regained! Is it not beautifully simple?"

"Way to Fire Mountain! But I don't understand," answered Martin.
