As they rode out from the narrow pass, down the mountain-side, and came into the valley, it was the most natural thing in the world for them to start their swift mustangs on a free gallop; not directly toward the camping-place, for they knew well enough that no girls of any age would be permitted to approach very near to warriors gathered in council. Away to the right they rode, following the irregular curve of the valley, side by side, managing the fleet animals under them as if horse and rider were one person.

So it came to pass that before the warriors had completed their task the two girls had struck the trail along which the blue-coated cavalry had entered the valley.

"Rita, I see something."

"What is it?"

"Come! See! Away yonder."

Rita's eyes were as good as anybody's, always excepting Apaches' and eagles', and she could see the white fluttering object at which her adopted sister was pointing.

The marks of the wheels and all the other signs of that trail, as they rode along, were quite enough to excite a pair of young ladies who had never seen a road, a pavement, a sidewalk, or anything of the sort; but when they came to that white thing fluttering at the foot of a mesquite-bush they both sprung from their saddles at the same instant.

Ni-ha-be's keen black eyes searched them in vain, one after another, for anything she had ever seen before.

"Rita, you are born white. What are they?"
