kets lay; but a wide-awake fellow, eager to ascertain
under what conditions this fugitive brave could have secured such a
letter of recommendation from the man of science, who was supposed to
have utterly vanished from the haunts of men without leaving a single
trace behind, up to the hour that message came to Colonel Haywood.

Holding the paper up, and shaking it slightly, Frank started to put the
Moqui warrior on the rack.

"This belong to you, Havasupai?" he demanded, trying to assume a stern
manner, such as he believed would affect the other more or less, and be
apt to bring out straight answers to his leading questions.

"The white boy has said," answered the other, for an Indian seldom
answers in a direct way.

"Where did you get it?" Frank continued, slowly, as if feeling his way;
for he did not wish to alarm the Indian, knowing how obstinate a Moqui
may prove if he once suspects that he is being coaxed into betraying

The black, bead-like eyes were on the face of Frank as he put these

speaking about the loss of hair on the part of the noted scientist; and
then made rings with his fingers and thumbs which he clapped to his eyes
as though looking through a pair of spectacles.

Evidently the Moqui understood. Reading signs was a part of his early
education. In fact it comprised nearly four-fifths of all the Indian
knew.

"White boy heap wise; he know that the man give Havasupai talking paper.
Much great man; know all. Tell Havasupai about cliff men. Find much good
cook pot, heap more stuff in cave. Find out how cave men live. Write all
down in book. Send Havasupai one, promise. It is well!"

"But where did you meet him?" asked Frank; and he saw at once that this
was getting very near the danger line, judging from the manner in which
the Moqui acted; for he seemed to draw back, just as the alarmed
tortoise will hide its head in its shell at the first sign of peril.

"In canyon where picture rocks laugh at sun," the Indian slo
