"Now, I don't doubt," mocked Hal, "he has gone away firm in the belief that we'll keep his appointment."

"He'll wake up after a while," laughed Eph Somers.

After indulging in a second ice cream soda the submarine boys started down the street toward the Farnum shipyard where the Pollard boats were built.

As they passed a street corner they heard a cautious:

"Hss—sst!"

"Now, who threw that our way?" demanded the irrepressible Eph, turning swiftly. Then he added, in a tone so low that only his comrades could hear:

"Say, fellows, I'll bet that cost something!"

"That" was, a rather undersized little man, of perhaps thirty. Dark of hair, and sparkling of eye, the stranger's rather pallid face was partly covered, in front, by a short goatee, of the French "imperial" sort, and a moustache whose points were waxed out in fierce military fashion.

It was the stranger's apparel that had attracted Eph's notice particularly. The stranger was arrayed almost exquisite fashion; his clothes were of finest texture and latest Parisian type. His little, pointed shoes were almost as dainty as a girl's. Though the day was warm the stranger was gloved, and handled a cane in the head of which a handsome amethyst shone.
