They went by flitter--Asaki, one of his Hunter pilots, and the three from the _Queen_--lifting over the rim of mountains behind the fortress-palace and speeding north with the rising sun a flaming ball to the east. Below, the country was stark--rocks and peaks, deep purple shadows marking the veins of crevices. But that was swiftly behind and they were over a sea of greens, many shades of green, with yellow, blue, even red cutting into the general verdant carpet of treetops. Another chain of heights and then open land, swales of tall grass already burnt yellow by the steady sun. There was a river here, a crazy, twisted stream coiling nearly back upon itself at times. Once more broken land, land so ravished by prehistoric volcanic action that it was a grotesque nightmare of erosion-whittled outcrops and mesas. Asaki pointed to the east. There was a dark patch widening out into a vast wedge. "The swamp of Mygra. It has not yet been explored." "You could air map it," Tau began. The Chief Ranger was frowning. "Four flitters have been lost trying that. Com reports fail when they cross that last mountain ridge eastward. There is some sort of interference which we do not yet understand. Mygra is a place of death; later we may be able to travel along its fringe and then you shall see. Now--" He spoke to the pilot in his own tongue and the flitter pointed up-nose at an angle as they climbed over the highest peak they had yet seen in this mountainous land, to reach at last a country of open grass dotted with small forest stands. Jellico nodded approvingly. "Zoboru?" "Zoboru," Asaki assented. "We shall go up to the northern end of the preserve. I wish to show you the roosts of the fastals. This is their nesting season and the sight is one you will long remember. But we shall take an eastern course; I have two Ranger stations to check on the way." It was after they left the second station that the flitter swung farther out eastward, again climbing over the chain of heights to sight one of the newly discovered wonders the staff at the last station had reported--a crater lake. And the flitter skimmed down across water which was a rich emerald in hue, filling the crater from one rock wall to the other with no beach at the foot of those precipitant cliffs. As the machine arose to clear the far wall, Dane tensed. One of his duties aboard the _Queen_ was flitter pilot for planetwise trips. And ever since they had taken off that morning he had unconsciously flown with the Khatkan pilot, anticipating each change or adjustment of the controls. Now he felt that sluggish response to the other's lift signal, and instinctively his own hand went out to adjust a power feed lever.
