e on slowly with the
walking teams. I had gone for some distance before I heard hoofs on the
sand behind me.

"Guess who it is," called a voice. "Don't turn your head."

"I can't turn," I answered; "but I know who it is."

She rode up alongside, where I could see her; and fair enough she was to
look upon, and glad enough I was to look. She was thinner now with this
prairie life, and browner, and the ends of her hair were still
yellowing, like that of outdoors men. She still was booted and gloved
after the fashion of civilization, and still elsewise garbed in the
aboriginal costume, which she filled and honored graciously. The metal
cylinders on her leggins rattled as she rode.

"You ought not to ride," she said. "You are pale."

"You are beautiful," said I; "and I ride because you are beautiful."

Her eyes were busy with her gloves, but I saw a sidelong glance. "I do
not understand you," she said, demurely.

"I could not sit back there in the wagon and think," said I. "I knew

Many things I had studied before then, for certain mysteries had come to
me, as to many men, who wish logically to know the causes of great
phenomena. From boyhood I had pondered many things. I had lain on my

fancied that it was a pale, blue flaming oblate, somewhere near my back
and in the middle of my body--such was my boyish guess of what they told
me was a real thing. I had pondered on that compass of the skies by
which the wild fowl guide themselves. I had wondered, as a child, how
far the mountains ran. As I had grown older I had read the law, read of
the birth of civilization, pondered on laws and customs. Declaring that
I must know their reasons, I had read of marriages in many lands, and
many times had studied into the questions of dowry and bride-price, and
consent of parents, and consent of the bride--studied marriage as a
covenant, a contract, as a human and a so-called divine thing. I had
questioned the cause of the old myth
