The call of a bird brought his attention back. Life was waking in the mountain forest where he stood. Gay-plumaged creatures, not unlike earthly parrots, were fluttering from tree to tree. The sound of a grunting came toward him. He swung about. His eyes encountered those of other life. A creature such as he had never seen was coming out of a quivering mass of sturdy fern. It had small, beady eyes and a snout like a pig. Two tusks sprouted from its jaws like the tusks of a boar. But the rest of the body, although something like that of a hog, was covered with a long wool-like hair, fine and seemingly almost silken soft.
This, as he was to learn later, was the tabur, an animal still wild on Palos, though domesticated and raised both for its hair, which was woven into fabrics, and for its flesh, which was valued as food. While Croft watched, it began rooting about the foot of a tree on one side of the small glade where he stood. Plainly it was hunting for something to eat.
Once more he turned to the plain and stood lost in something new. Across the dun reaches of the desert, beyond the green region of the river, was moving a long dark string of figures, headed toward the city he had seen. It was like a caravan, Croft thought, in its arrangement, save that the moving objects which he deemed animals of some sort, belonged in no picture of a caravan such as he had ever seen.
Swiftly he willed himself toward them and moved along by their side. Something like amazement filled his being. These beasts were such creatures as might have peopled the earth in the Silurian age. They were huge, twice the size of an earthly elephant. They moved in a majestic fashion, yet with a surprising speed. Their bodies were covered with a hairless skin, reddish pink in color, wrinkled and warted and plainly extremely thick. It slipped and slid over the muscles beneath it as they swung forward on their four massive legs, each one of which ended in a five-toed foot armed with short heavy claws.
But it was the head and neck and tail of the things which gave Croft pause. The head was more that of a sea-serpent or a monster lizard than anything else. The neck was long and flexible and curved like that of a camel. The tail was heavy where it joined the main spine, but thinned rapidly to a point. And the crest of head and neck, the back of each creature, so far as he could see, was covered with a sort of heavy scale, an armor devised by nature for the thing's protection, as it appeared. Yet he could not see very well, since each Sarpelca, as he was to learn their Palosian name, was loaded heavily with bundles and bales of what might be valuable merchandise.
And on each sat a man. Croft hesitated not at all to give them that title, since they were strikingly like the men of earth in so far as he could see. They had heads and arms and legs and a body, and their faces were white. Their features departed in no particular, so far as he could see, from the faces of earth, save that all were smooth, with no evidence of hair on upper lip or cheek or chin.
They were clad in loose cloak-like garments and a hooded cap or cowl. They sat the Sarpelcas just back of the juncture of the body and neck, and guided the strange-appearing monsters by means of slender reins affixed to two of the fleshy tentacles which sprouted about the beast's almost snakelike mouths.
That this strange cortège was a caravan Croft was now assured. He decided to follow it to the city and inspect that as well. Wherefore he kept on beside it down the valley, along what he now saw was a well-defined and carefully constructed road, built of stone, cut to a nice approximation, along which the unwieldy procession made good time. The road showed no small knowledge of engineering. It was like the roads of Ancient Rome, Croft thought with quickened interest. It was in a perfect state of preservation and showed signs of recent mending here and there. While he was feeling a quickened interest in this the caravan entered the cultivated region along the river, and Croft gave his attention to the fields.
The first thing he noted here was the fact that all growth was due to irrigation, carried out by means of ditches and laterals very much as on earth at the present time. Here and there as the caravan passed down the splendid road he found a farmer's hut set in a bower of trees. For the most part they were built of a tan-colored brick, and roofed with a thatching of rushes from the river's bank. He saw the natives working in the fields, strong-bodied men, clad in what seemed a single short-skirted tunic reaching to the knees, with the arms and lower limbs left bare.
