staggered ahead, seeking
to recover his balance. Without a doubt he would have done so, but,
just then, the floor under his feet ended. With a yell of dismay, the
submarine boy tottered, then plunged down, alighting on a bed of soft
dirt many feet below.

CHAPTER VII

JACK FINDS SOMETHING "NEW," ALL RIGHT

Jack Benson was on his feet in an instant. An angrier boy it would have
been hard to find.

From overhead came the sound of a loud guffaw.

"Oh, you infernal scoundrel!" raged the submarine boy, shaking his fist
in the dark.

"W'at am de matter wid yo', w'ite trash?" came the jeering query.

"Let me get my hands on you, and I'll show you!" quivered Benson.

"Yah! Listen to yo'! Yo' wait er minute, an' Ah'll show yo' a light."

Gr-r-r-r! Gr-r-r-r t That sound from overhead was not pleasant. Jack,
in the few seconds that were left to him, could only guess as to the
cause of the sounds. Then, some fifteen feet over his head, a tiny
flame sputtered. This match-end was carried to the wick of the lantern
that the yellowish guide had been carrying, and now the light illumined
the place into which Jack Benson had fallen.

That place was a square-shaped pit, with boarded sides. Up above, on
a shelf of flooring, knelt the late guide, grinning down with a look
of infernal glee. On either side of the mulatto stood a heavy-jowled
bull-dog. Both brutes peered down, showing their teeth in a way to
make a timid man's blood run cold.

"Put those dogs back and come down here," challenged Jack, shaking
his fist. "Come down, and I'll teach you a few things, you rascal!"

"Don' yo' shake yo' fist at me, or dem dawgs will sure jump down and
tackle yo'," grinned the guide, gripping at the collars of the brutes,
which, truly, showed signs of intending to spring below.

Jack fell back, his hands dropping to his sides. Had there been but
one dog, the submarine boy, with all his grit forced to the surface,
might have chosen to face the brute, hoping to despatch it with a
well-aimed kick. But with two dogs, both intent on "getting" him,
young Benson knew that he would stand the fabled chance of a snow-flake
on a red-hot stove.

"Dat's right, gemmun, yo' keep cool," observed the mulatto, mockingly.

"You've decoyed me--trapped me here with a mess of lies," flung back
Captain Jack, angrily. "What's your game?"

"Dis am a free lodgin' house--ho, ho, ho!" chuckled the late guide.
"Ah's gwine gib yo' er pla
