"We take two extra horses for remounts," Shan Kar said.

The wolf ventured no comment. But Nelson wondered if he guessed that the extra mounts were intended for Kree and Nsharra.

The next instant it was swept from his mind by a disturbing shock. The horses tossed their heads excitedly against their cruel-bitted bridles and uttered eager thoughts that sounded in Nelson's brain.

"It's the Hairy One!" they cried. "Tark!"

"These horses of yours are talking to the bloody wolf!" cried the Cockney to Shan Kar.

Shan Kar answered curtly. "All the clans in this valley are intelligent. These Hoofed Ones are our prisoners of war."

"Slaves, say rather!" flashed the passionate thought of the golden mare in the forefront. "Slaves, beaten into beasts of burden by the Humanites! Tark, do they know this in Vruun?"
