Edgar Rice Burroughs: Warlord of Mars

2. CHAPTER II : UNDER THE MOUNTAINS (continued)

This omission I now made haste to correct, and, after the manner of green Martians with their beasts, I let him know partially by the weird and uncanny telepathy of Barsoom and partly by word of mouth that we were upon the trail of those who had recently occupied the boat through which we had just passed.

A soft purr, like that of a great cat, indicated that Woola understood, and then, with a word to him to follow, I turned to the right along the ledge, but scarcely had I done so than I felt his mighty fangs tugging at my leathern harness.

As I turned to discover the cause of his act he continued to pull me steadily in the opposite direction, nor would he desist until I had turned about and indicated that I would follow him voluntarily.

Never had I known him to be in error in a matter of tracking, so it was with a feeling of entire security that I moved cautiously in the huge beast's wake. Through Cimmerian darkness he moved along the narrow ledge beside the boiling rapids.

As we advanced, the way led from beneath the overhanging cliffs out into a dim light, and then it was that I saw that the trail had been cut from the living rock, and that it ran up along the river's side beyond the rapids.

For hours we followed the dark and gloomy river farther and farther into the bowels of Mars. From the direction and distance I knew that we must be well beneath the Valley Dor, and possibly beneath the Sea of Omean as well--it could not be much farther now to the Temple of the Sun.

Even as my mind framed the thought, Woola halted suddenly before a narrow, arched doorway in the cliff by the trail's side. Quickly he crouched back away from the entrance, at the same time turning his eyes toward me.

Words could not have more plainly told me that danger of some sort lay near by, and so I pressed quietly forward to his side, and passing him looked into the aperture at our right.
