There was a scurry of movement behind Barber and another of the little animals, a white one, hurried past them. It went to the yellow one and they stood close together as they stared up. Apparently they were mates.⁠ ⁠…

“That’s the other one⁠—those are the two that mocked us,” Barber said, and thereby gave them the name by which they would be known: mockers.

The mockers were fresh meat⁠—but they accepted the humans with such friendliness and trust that Barber lost all his desire to have one for supper or for any other time. They had a limited supply of dried meat and there would be plenty of orange corn. They would not go hungry.

They discovered that the mockers had living quarters in both the cool caves and the ones warmed by the hot springs. There was evidence that they hibernated during the winters in the warm caves.

There were no minerals in the mockers’ valley and they set out to continue their circuit of the chasm. They did not get far until the heat had become so great that the chasm’s tributaries began going dry. They turned back then, to wait in the little valley until the fall rains came.

When the long summer was ended by the first rain they resumed their journey. They took a supply of the orange corn and two of the mockers; the yellow one and its mate. The other mockers watched them leave, standing silent and solemn in front of their caves as though they feared they might never see their two fellows or the humans again.

The two mockers were pleasant company, riding on their shoulders and chattering any nonsense that came to mind. And sometimes saying things that were not at all nonsense, making Humbolt wonder if mockers could partly read human minds and dimly understand the meaning of some of the things they said.
