she did the same in the morning when she first viewed the sun. At
first I had not connected her act with anything in particular, but
after we learned to converse and she had explained a little of her
religious superstitions, I realized that she was making the sign
of the triangle as a Roman Catholic makes the sign of the cross.
Always the short side of the triangle was uppermost. As she
explained all this to me, she pointed to the decorations on her

significance of this particular geometric figure, I at once grasped
its appropriateness.

We were now in the country of the Band-lu, the spearmen of Caspak.
Bowen had remarked in his narrative that these people were analogous
to the so-called Cro-Magnon race of the Upper Paleolithic, and I was
therefore very anxious to see them. Nor was I to be disappointed;
I saw them, all right! We had left the Sto-lu country and literally
fought our way through cordons of wild beasts for two days when
we decided to make camp a little earlier than usual, owing to the
fact that we had reached a line of cliffs running east and west in
which were numerous likely cave-lodgings. We were both very tired,

the opening was so small that we had to lie flat and wriggle through
it to gain ingress, while the interior was high-ceiled and spacious.
I lighted a faggot and looked about; but as far as I could see,
