I noticed during the period of this new persecution that the beasts appeared only when our backs were turned; we never saw one really materialize from thin air, nor did I for an instant sufficiently lose my excellent reasoning faculties to be once deluded into the belief that the beasts came into the room other than through some concealed and well-contrived doorway.

Among the ornaments of Tars Tarkas' leather harness, which is the only manner of clothing worn by Martians other than silk capes and robes of silk and fur for protection from the cold after dark, was a small mirror, about the bigness of a lady's hand glass, which hung midway between his shoulders and his waist against his broad back.

Once as he stood looking down at a newly fallen antagonist my eyes happened to fall upon this mirror and in its shiny surface I saw pictured a sight that caused me to whisper:

"Move not, Tars Tarkas! Move not a muscle!"

He did not ask why, but stood like a graven image while my eyes watched the strange thing that meant so much to us.
