u might have recognized both
their mounts; for they left them here at noon to-day."

"Noon!" echoed Bob; "then they made mighty good work of it, to get ahead
of us all that time. I reckon you're going to tell me they've gone down
into the canyon, and put in several hours looking for their birds, the
two fellows who've given 'em the merry laugh more'n a few times."

"Guessed right the first shot," Frank went on, "but all that doesn't
concern us one half as much as some other information I struck."

"And you've been keeping it back from me, while we stood there on the
piazza, admiring the wonderful view," Bob remarked, with a touch of
reproach in his voice.

"There were people passing us, all the time," his chum explained; "and
besides, I wanted to keep it until we were alone, so we could talk it
over."

"Is it about that scheming cousin of your father's--what did you say his
name was--Eugene Warringford?"

"You got it straight enough," Frank admitted; "and what I learned, was
about him. I saw his name on the register, and he's somewhere about the

"The same Abajo," his chum continued; "which proves that those two are
bound up in a plot to win this game. If Eugene can only find Uncle Felix
he intends to get that paper in his possession, by fair means or foul."

"Then it's up to us to put a stopper in his little bottle!" declared
Bob.

"I'm wondering," Frank proceeded, "whether they've got any idea where to
look for the man who has hidden himself away for three years. Perhaps
they mean to keep tabs on us, and if we are lucky enough to discover
Uncle Felix, they hope to jump in, and snatch away the prize before we
can warn him."

"Say, this is getting to be a pretty mix-up all around," laughed the
Kentucky lad. "Here we are, meaning to try and follow the old Moqui; or
failing that, wait for him to fetch us a message from the hermit of Echo
Cave. Then Eugene, and his shadow, Abajo, are hanging around with the
idea of beating us at our game. Havasupai on his part will be he
