It was my first trip upon the bosom of Iss, and the things I saw there will live forever in my memory.

Terrible as they were, they could not have commenced to approximate the horrible conditions which must have obtained before Tars Tarkas, the great green warrior, Xodar, the black dator, and I brought the light of truth to the outer world and stopped the mad rush of millions upon the voluntary pilgrimage to what they believed would end in a beautiful valley of peace and happiness and love.

Even now the low islands which dotted the broad stream were choked with the skeletons and half devoured carcasses of those who, through fear or a sudden awakening to the truth, had halted almost at the completion of their journey.

In the awful stench of these frightful charnel isles haggard maniacs screamed and gibbered and fought among the torn remnants of their grisly feasts; while on those which contained but clean-picked bones they battled with one another, the weaker furnishing sustenance for the stronger; or with clawlike hands clutched at the bloated bodies that drifted down with the current.

Thurid paid not the slightest attention to the screaming things that either menaced or pleaded with him as the mood directed them—evidently he was familiar with the horrid sights that surrounded him. He continued up the river for perhaps a mile; and then, crossing over to the left bank, drew his craft up on a low ledge that lay almost on a level with the water.

I dared not follow across the stream, for he most surely would have seen me. Instead I stopped close to the opposite wall beneath an overhanging mass of rock that cast a dense shadow beneath it. Here I could watch Thurid without danger of discovery.

The black was standing upon the ledge beside his boat, looking up the river, as though he were awaiting one whom he expected from that direction.

As I lay there beneath the dark rocks I noticed that a strong current seemed to flow directly toward the center of the river, so that it was difficult to hold my craft in its position. I edged farther into the shadow that I might find a hold upon the bank; but, though I proceeded several yards, I touched nothing; and then, finding that I would soon reach a point from where I could no longer see the black man, I was compelled to remain where I was, holding my position as best I could by paddling strongly against the current which flowed from beneath the rocky mass behind me.

I could not imagine what might cause this strong lateral flow, for the main channel of the river was plainly visible to me from where I sat, and I could see the rippling junction of it and the mysterious current which had aroused my curiosity.

While I was still speculating upon the phenomenon, my attention was suddenly riveted upon Thurid, who had raised both palms forward above his head in the universal salute of Martians, and a moment later his “Kaor!” the Barsoomian word of greeting, came in low but distinct tones.
