Mars’ long-dead seas, in the bottom of which my encounter with the Martians had taken place.
    In a short time we gained the foot of the mountains, and after traversing a narrow gorge came to an open valley, at the far extremity of which was a low table land upon which I beheld an enormous city. Toward this we galloped, entering it by what appeared to be a ruined roadway leading out from the city, but only to the edge of the table land, where it ended abruptly in a flight of broad steps.
    Upon closer observation I saw as we passed them that the buildings were deserted, and while not greatly decayed had the appearance of not having been tenanted for years, possibly for ages. Toward the center of the city was a large plaza, and upon this and in the buildings immediately surrounding it were camped some nine or ten hundred creatures of the same breed as my captors, for such I now considered them despite the suave manner in which I had been trapped.
    With the exception of their ornaments all were naked. The women varied in appearance but little from the men, except that their tusks were much larger in proportion to their height, in some instances curving nearly to their high-set ears. Their bodies were smaller and lighter in color, and their fingers and toes bore the rudiments of nails, which were entirely lacking among the males. The adult females ranged in height from ten to twelve feet.
    The children were light in color, even lighter than the women, and all looked precisely alike to me, except that some were taller than others; older, I presumed.
    I saw no signs of extreme age among them, nor is there any appreciable difference in their appearance from the age of maturity, about forty, until, at about the age of one thousand years, they go voluntarily upon their last strange pilgrimage down the river Iss, which leads no living Martian knows whither and from whose bosom no Martian has ever returned, or would be allowed to live did he return after once embarking upon its cold, dark waters.
    Only about one Martian in a thousand dies of sickness or disease, and possibly about twenty take the voluntary pilgrimage. The other nine hundred and seventy-nine die violent deaths in duels, in hunting, in aviation and in war; but perhaps by far the greatest death loss comes during the age of childhood, when vast numbers of the little Martians fall victims to the great white apes of Mars.
    The average life expectancy of a Martian after the age of maturity is about three hundred years, but would be nearer the one-thousand mark were it not for the various means leading to violent death. Owing to the waning resources of the planet it evidently became necessary to counteract the increasing longevity which their remarkable skill in therapeutics and surgery produced, and so human life has come to be considered but lightly on Mars, as is evidenced by their dangerous sports and the almost continual warfare between the various communities.
    There are other and natural causes tending toward a diminution of population, but nothing contributes so greatly to this end as the fact that no male or female Martian is ever voluntarily without a weapon of destruction.
    As we neared the plaza and my presence was discovered we were immediately surrounded by hundreds of the creatures who seemed anxious to pluck me from my seat behind my guard. A word from the leader of the party stilled their clamor, and we proceeded at a trot across the plaza to the entrance of as magnificent an edifice as mortal eye has rested upon.
    The building was low, but covered an enormous area. It was constructed of gleaming white marble inlaid with gold and brilliant stones which sparkled and scintillated in the sunlight. The main entrance was some hundred feet in width and projected from the building proper to form a huge canopy above the entrance hall. There was no stairway, but a gentle incline to the first floor of the building opened into an enormous chamber encircled by
