Raf fastened on the helmet and started away from the flitter. The buzz which he had expected to roar in his ears :~ was only a faint drone, and above it he could easily hear other sounds. Yet it was there, and he tested it by a series of loops away from the flyer. Each time as he came on the true beam he was rewarded by a deepening of the muted note. Yes, he could be a homer with that, and at the same time” be alert to any other noise in his vicinity.
“That’s it!” He paid credit where it was due. But he was unable to break his long habit of silence. Something within: him still kept him wary of the com-tech’s open friendliness=
None of the aliens approached the flitter as the shadows began to draw in. The procession of moving teams stopped, and most of the burden-bearing warriors withdrew to the.: globe and stayed there. Soriki pointed this out.
“They’re none too sure, themselves. Look as if they are’ closing up for the night.”
Indeed it did. The painted men had hauled up their ramp, the hatch in the globe closed with a definite snap. Seeing that, the com-tech laughed.
“We have a double reason for a strict watch. Suppose
J whatever they’ve been looking for jumps us? They’re not worrying over that it now appears.”
So they took watch and watch, three hours on and three hours in rest. When it came Raf’s turn he did not remain sitting in the flitter, listening to the com-tech’s heavy breathing, but walked a circular beat which took him into the darkness of the night in a path about the flyer. Overhead the stars were sharp and clear, glittering gem points. But in the dead city no light showed, and he was sure that no aliens camped there tonight.
He was sleeping when Soriki’s grasp on his shoulder brought him to that instant alertness he had learned on field maneuvers half the Galaxy away.
“Business,” the com-tech’s voice was not above a whisper as he leaned over the pilot. “I think they are on the move.”
The light was the pale gray of pre-dawn. Raf pulled himself up with caution to look at the globe. The com-tech was right. A dark opening showed on the alien ship; they had released their hatch. He fastened his tunic, buckled on his equipment belt and helmet, strapped his boots.
“Here they come!” Soriki reported. “One-two-five-no, six of them. And they’re heading for the city. No dollies with them, but they’re all armed.”
Together the Terrans watched that patrol of alien warriors, their attitude suggesting that they hoped to pass unseen, hurry toward the city. Then Raf slipped out of the flyer. His dark clothing in this light should render him largely invisible.
Soriki waved encouragingly and the pilot answered with a quick salute before he sped after his quarry.

A HOUND IS LOOSED
DALGARD’S FEET touched gravel; he waded cautiously to the bank, where a bridge across the river made a concealing shadow on the water. None of the mermen had accompanied him this far. Sssuri, as soon as his human comrade had started for the storage city, had turned south to warn and rally the tribes. And the merpeople of the .islands had instituted a loose chain of communication, which led from a clump of water reeds some two miles back to the seashore, and so out to the islands. Better than any of the now legendary coms of his Terran forefathers were these minds of the spies in hiding, who could pick up the racing thoughts beamed to them and pass them on to their fellows.
Although there were no signs of life about the city, Dalgard moved with the same care that he would have used in penetrating a snake-devil’s lair. In the first hour of dawn he had contacted a hopper. The small beast had been frightened almost out of coherent thought, and Dalgard had had to spend some time in allaying that terror to get a fractional idea of what might be going on in this countryside.
Death-the hopper’s terror had come close to insanity. Killers had come out of the sky, and they were burning- All living things were fleeing before them. And in that moment Dalgard had been forced to give up his plan for an unseen spy ring, which would depend upon the assistance of the animals. His information must come via his own eyes and ears.
So he kept on, posting the last of the mermen in his mental relay well away from the city, but swimming upstream himself. Now that he was here, he could see no traces of the invaders. Since they could not have landed their sky ships in the thickly built-up section about the river, it must follow that their camp lay on the outskirts of the metropolis.
He pulled himself out of the water. Bow and arrows had been left behind with the last merman; he had only his sword-knife for protection. But he was not there to fight, only to watch and wait. Pressing the excess moisture out of his scant clothing, he crept along the shore. If the strangers were using the streets, it might be well to get above them. Speculatively he eyed the buildings about him as he entered the city.
Dalgard continued to keep at street level for two blocks, darting from doorway to shadowed doorway, alert not only to any sound but to any flicker of thought. He was reasonably sure, however, that the aliens would be watching and seeking only for the merpeople. Though they were not telepathic as their former slaves, Those Others were able to sense the near presence of a merman, so that the sea people dared not communicate while within danger range of the aliens without betraying themselves. It was the fact that he was of a different species therefore possibly immune to such detection, which had brought Dalgard into the city.
He studied the buildings ahead. Among them was a cone.
Ts‘trfGcture which might have been the base of a tower that had had all stories above the third summarily amputated. It was ornamented with a series of bands in high relief, bands bearing the color script of the aliens. This was the nearest answer to his problem. However the scout did not move toward it until after a long moment of both visual and mental inspection of his surroundings. But that inspection did not reach some twelve streets away where another crouched to watch. Dalgard ran lightly to the tower at the same moment that Raf shifted his weight from one foot to the other behind a parapet as he spied upon the knot of aliens gathered below him in the street . . . .
The pilot had followed them since that early morning hour when Soriki had awakened him. Not that the chase had led him far in distance. Most of the time he had spent in waiting just as he was doing now. At first he had believed 4 that they were searching for something, for they had ventured a into several buildings, each time to emerge conferring, only, to hunt out another and invade it. Since they always re-,l turned with empty hands, he could not believe that they were out for further loot. Also they moved with more confidence than they had shown the day before. That confidence led Raf to climb above them so that he could watch them with less chance of being seen in return.
It had been almost noon when they had at last come into this section. If two of them had not remained idling on the street as the long moments crept by, he would have believed l that they had given him the slip, that he was now a cat watching a deserted mouse hole. But at the moment they > were coming back, carrying something.
Raf leaned as far over the parapet as he dared, trying to catch a better look at the flat, boxlike object two of them had deposited on the pavement. Whatever it was either needed some adjustment or they were attempting to open .it with poor success, for they had been busied about it for what seemed an unusually long time. The pilot licked dry.. lips and wondered what would happen if he swung down there and just walked in for a look-see. That idea was hardening, into resolution when suddenly the group below drew, quickly apart, leaving the box sitting alone as they formed a ; circle about it.
There was a puff of white vapor, a protesting squawk, and the thing began to rise in jerks as if some giant in the sky was pulling at it spasmodically. Raf jumped back. Before he could return to his vantage point, he saw it rise above the edge of the parapet, reach a level some five or six feet above his head, hovering there. It no longer climbed; instead it began to swing back and forth, describing in each swing a wider stretch of space. x
