Toller could foresee the interplanetary crossing, like so many other historic and glorious adventures, being conducted in squalor and degradation, becoming a test of physical and mental endurance which not all would survive.
In contrast to the meanness and compression of the gondola, the upper element of the skyship was awesomely spacious, rarified, a giant form almost without substance. The linen panels of the envelope had been dyed dark brown to absorb the sun’s heat and thereby gain extra lift, but when Toller looked up into it through the open mouth he could see light glowing through the material. The seams and horizontal and vertical load tapes appeared as a geometric web of black lines, emphasising the vastness of the balloon’s curvatures. Up there was the gossamer dome of a cloud-borne cathedral, impossible to associate with the handiwork of mere weavers and stitchers.
Satisfied that the ship was stable and ascending steadily, Toller gave the order for the four acceleration struts to be drawn in and attached by their lower ends to the corners of the gondola. Renn completed the task within a few minutes, imparting to the balloon/gondola assemblage the slight degree of structural stiffness needed to cope with the modest forces which would act on it when the drive or attitude jets were in use.
Attached to a lashing hook at the pilot’s station was the rip line, dyed red, which ran up through the balloon to a crown panel which could be torn out for rapid deflation. As well as being a safety device it served as a rudimentary climb speed indicator, becoming slack when the crown was depressed by a strong vertical air flow. Toller fingered the line and estimated that they were ascending at about twelve miles an hour, aided by the fact that the miglign gas was slightly lighter than air even when unheated. Later he would almost double that speed by using the drive jet when the ship entered the regions of low gravity and attenuated air.
Thirty minutes into the flight the ship was high above the summit of Mount Opelmer and had ceased its eastward drift. The garden province of Kail stretched to the southern horizon, its strip farms registering as a shimmering mosaic, with each tessera striated in six different shades varying from yellow to green. To the west was the Otollan Sea and to the east was the Mirlgiver Ocean, their curving blue reaches flecked here and there by sailing ships. The ochraceous mountains of Upper Kolcorron filled the view to the north, their ranges and folds compacted by perspective. A few airships gleamed like tiny elliptical jewels as they plied the trade lanes far below.
From an altitude of some six miles the face of Land looked placid and achingly beautiful. Only the relative scarcity of airships and sailing craft indicated that the entire prospect, apparently drowsing in benign sunlight, was actually a battle-ground, an arena in which mankind had fought and lost a deadly duel.
Toller, as had become his habit when deep in thought, located the curiously massive object given to him by his father and rubbed his thumb over its gleaming surface. In the normal course of history, he wondered, how many centuries would men have waited before essaying the voyage to Overland? Indeed, would they ever have done so had they not been fleeing from the ptertha?
The thought of the ancient and implacable enemy prompted him to cast around and check on the position of the solitary globe he had detected earlier. Its lateral separation from the ship had not changed and, more significantly, it was still matching the rate of climb. Was that proof of sentience and purpose? If so, why had the ptertha as a species singled out man as the focus of its hostility? Why was it that every other creature on Land, with the exception of the Sorka gibbon, was immune to pterthacosis?
As though sensing Toller’s renewed interest in the globe, Zavotle lowered his binoculars and said, “Does it look bigger to you, captain?”
Toller picked up his own glasses and studied the purple-black smudge, finding that its transparency defied his attempts to define its boundaries. “Hard to say.”
“Littlenight will be here soon,” Zavotle commented. “I don’t relish the idea of having that thing hanging around us in the dark.”
“I don’t think it can close in — the ship is almost the same shape as a ptertha, and our response to a crosswind will be roughly similar.”
“I hope you’re right,” Zavotle said gloomily.
Rillomyner looked round from his post at a cannon and said, “We haven’t eated since dawn, captain.” He was a pale and pudgy young man with an enormous appetite for even the vilest food, and it was said that he had actually gained weight since the beginning of the shortages by scavenging all the substandard food rejected by his workmates. In spite of a show of diffidence, he was a good mechanic and intensely proud of his skills.
“I’m glad to hear your gut is back to its normal condition,” Toller said. “I would hate to think I had done it some permanent mischief with my handling of the ship.”
“I didn’t mean to criticise the take-off, captain — it’s just that I have always been cursed with this weak stomach.”
Toller clicked his tongue in mock sympathy and glanced at Flenn. “You’d better feed this man before he becomes faint.”
“Right away, captain.” As Flenn was getting to his feet his shirt parted at the chest and the green-striped head of a carble peered out. •Flenn hastily covered the furry creature with his hand and pushed it back into concealment.
“What have you got there?” Toller snapped.
“Her name is Tinny, captain.” Flenn brought the carble out and cradled it in his arms. “There was nobody I could leave her with.”
Toller sighed his exasperation. “This is a scientific mission, not a… Do you realise that most commanders would put that animal over the side?”
“I swear she won’t be any trouble, captain.”
“She’d better not. Now get the food.”
Flenn grinned and, agile as a monkey, disappeared into the galley to prepare the first meal of the voyage. He was small enough to be completely hidden by the woven partition which was chest high to the rest of the crew. Toller settled down to refining his control over the ship’s ascent.
Deciding to increase speed, he lengthened the burns from three to four seconds and watched for the time-lagged response of the balloon overhead. Several minutes went by before the extra lift he was generating overcame the inertia of the many tons of gas inside the envelope and the rip line became noticeably slacker. Satisfied with a new rate of climb of around eighteen miles an hour, he concentrated on making the burner rhythm — four seconds on and twenty off — part of his awareness, something to be paced by the internal clocks of his heart and lungs. He needed to be able to detect the slightest variation in it even when he was asleep and being spelled at the controls by Zavotle.
The food served up by Flenn was from the limited fresh supplies and was better than Toller had expected — strips of reasonably lean beef in gravy, pulse, fried grain-cakes and beakers of hot green tea. Toller stopped operating the burner while he ate, allowing the ship to coast upwards in silence on stored lift. The heat emanating from the black combustion chamber mingled with the aromatic vapours issuing from the galley, turning the gondola into a homely oasis in a universe of azure emptiness.
Partway through the meal littlenight came sweeping from the west, a brief flash of rainbow colours preceding a sudden darkness, and as the crew’s eyes adjusted the heavens blazed into life all around them. They reacted to the unearthliness of their situation by generating an intense camaraderie. There was an unspoken conviction that lifelong friendships were being formed, and in that atmosphere every anecdote was interesting, every boast believable, every joke profoundly funny. And even when the talk eventually died away, stilled by strangeness, communication continued on another plane.
