Slowly, after the manner of locomotion habitual to the Mahars, when they are not using their wings, we crept through throngs of busy slaves, Sagoths, and Mahars.  After what seemed an eternity we reached the outer door which leads into the main avenue of Phutra.  Many Sagoths loitered near the opening.  They glanced at Ghak as he padded between them.  Then Perry passed, and then Hooja.  Now it was my turn, and then in a sudden fit of freezing terror I realized that the warm blood from my wounded arm was trickling down through the dead foot of the Mahar skin I wore and leaving its tell-tale mark upon the pavement, for I saw a Sagoth call a companion’s attention to it.

The guard stepped before me and pointing to my bleeding foot spoke to me in the sign language which these two races employ as a means of communication.  Even had I known what he was saying I could not have replied with the dead thing that covered me.  I once had seen a great Mahar freeze a presumptuous Sagoth with a look.  It seemed my only hope, and so I tried it.  Stopping in my tracks I moved my sword so that it made the dead head appear to turn inquiring eyes upon the gorilla-man.  For a long moment I stood perfectly still, eyeing the fellow with those dead eyes.  Then I lowered the head and started slowly on.  For a moment all hung in the balance, but before I touched him the guard stepped to one side, and I passed on out into the avenue.

On we went up the broad street, but now we were safe for the very numbers of our enemies that surrounded us on all sides.  Fortunately, there was a great concourse of Mahars repairing to the shallow lake which lies a mile or more from the city.  They go there to indulge their amphibian proclivities in diving for small fish, and enjoying the cool depths of the water.  It is a fresh-water lake, shallow, and free from the larger reptiles which make the use of the great seas of Pellucidar impossible for any but their own kind.

In the thick of the crowd we passed up the steps and out onto the plain.  For some distance Ghak remained with the stream that was traveling toward the lake, but finally, at the bottom of a little gully he halted, and there we remained until all had passed and we were alone.  Then, still in our disguises, we set off directly away from Phutra.

The heat of the vertical rays of the sun was fast making our horrible prisons unbearable, so that after passing a low divide, and entering a sheltering forest, we finally discarded the Mahar skins that had brought us thus far in safety.

I shall not weary you with the details of that bitter and galling flight.  How we traveled at a dogged run until we dropped in our tracks.  How we were beset by strange and terrible beasts.  How we barely escaped the cruel fangs of lions and tigers the size of which would dwarf into pitiful insignificance the greatest felines of the outer world.

On and on we raced, our one thought to put as much distance between ourselves and Phutra as possible.  Ghak was leading us to his own land—­the land of Sari.  No sign of pursuit had developed, and yet we were sure that somewhere behind us relentless Sagoths were dogging our tracks.  Ghak said they never failed to hunt down their quarry until they had captured it or themselves been turned back by a superior force.
