y
hand instantly closed, except the forefinger, and gave three distinctive
jerks that almost elevated my elbow from its position. A negative reply
was soon given to a subsequent question by a single jerk of the hand;
and thus I was enabled to hold a conversation in monosyllables with my
invisible companions.

It is unnecessary to detail the whole of the interview which followed. I
will only add that portion of it which is intimately connected with this
narrative. Strange as it may appear, I had until this moment forgotten
all about the beautiful apparition that appeared and disappeared so

Was I dreaming, or was the vision real, that my eyes beheld? This was
the first calm thought that coursed through my brain, after the terror
and amazement had subsided. Awe-struck I certainly was, when the
beautiful phantom first rose upon my sight, at Castillo; awe-struck once
more, when she again appeared, amid the gray old rains of _Casa Grande_.
I have listened very often to the surmises of others, as they detailed
what _they_ would do, were a supernatural being to rise up suddenly
before them. Some have said, they would gaze deliberately into the face
of the phantom, scan its every feature, and coolly note down, for the
benefit of others, how long it "walked," and in what manner it fad
