Sssuri still kept to the fields, avoiding the highway, until mid-morning, and then he made an abrupt turn and brought them out on the soil-drifted surface of the road. The land here was seemingly deserted. No moth birds performed their air ballets overhead, and they did not see a single hopper. That is, they did not until the road dipped before them and they started down into a cupped hollow filled with buildings. The river, whose delta they had earlier seen, made a half loop about the city, lacing it in. And here were no signs of the warfare which had ruined the port. But in the middle of the road lay a bloody bunch of fur and splintered bone, insects busy about it. Sssuri used the point of his spear to straighten out the small corpse, displaying its headlessness. And before they reached the outer buildings of the city they found four more hoppers all mangled. "Not a snake-devil," Dalgard deduced. As far as he knew only the huge reptiles or their smaller flying-dragon cousins preyed upon animals. But a snake-devil would have left no remains of anything as small as a hopper, one mouthful which could not satisfy its gnawing hunger. And a flying dragon would have picked the bones clean. "_Them_!" Sssuri's reply was clipped. "They hunt for sport." Dalgard felt a little sick. To his mind, hoppers were to be treated with friendship. Only against the snake-devils and the flying dragons were the colonists ever at war. No wonder that hopper had run from them back on the plain during yesterday's journey! The buildings before them were not the rounded domes of the isolated farms, but a series of upward-pointing shafts. They walked through a tall gap which must have supported a now-disappeared barrier gate, and their passing was signaled by a whispering sound as they shuffled through the loose sand and soil drifted there in a miniature dune. This city was in a better state of preservation than any Dalgard had previously visited. But he had no desire to enter any of the gaping doorways. It was as if the city rejected him and his kind, as if to the past that brooded here he was no more than a curious hopper or a fluttering, short-lived moth bird. "Old--old and with wisdom hidden in it--" he caught the trail of thought from Sssuri. And he was certain that the merman was no more at ease here than he himself was. As the street they followed brought them into an open space surrounded by more imposing buildings, they made another discovery which blotted out all thoughts of forbidden knowledge and awakened them to a more normal and everyday danger. A fountain, which no longer played but gave birth to a crooked stream of water, was in the center. And in the muddy verge of the stream, pressed deep, was the fresh track of a snake-devil. Almost full grown, Dalgard estimated, measuring the print with his fingers. Sssuri pivoted slowly, studying the circle of buildings about them.
