"They're rations," said a second young man. "We don't go anywhere without rations, except Orede."
"Orede, yes. I think we were shooting at each other there," said Calhoun pleasantly. "Weren't we?"
"Yes," said the young man.
He was neither cordial nor antagonistic. He was impassive. Calhoun shrugged.
"Then we can take off immediately. Here's the communicator and there's the button. You might call the grid and arrange for us to be lifted."
The young man seated himself at the control-board. Very professionally, he went through the routine of preparing to lift by landing grid, which routine has not changed in two hundred years. He went briskly ahead until the order to lift. Then Calhoun stopped him.
"Hold it!"
He pointed to the air-lock. Both doors were open. The young man at the control-board flushed vividly. One of the others closed and dogged the doors.
The ship lifted. Calhoun watched with seeming negligence. But he found occasion for a dozen corrections of procedure. This was presumably a training voyage of his own suggestion. Therefore, when the blueskin pilot would have flung the Med Ship into undirected overdrive, Calhoun grew stern. He insisted on a destination. He suggested Weald.
The young men glanced at each other and accepted the suggestion. He made the acting pilot look up the intrinsic brightness of its sun and measure its apparent brightness from just off Dara. He made him estimate the change in brightness to be expected after so many hours in overdrive, if one broke out to measure.
The first blueskin student pilot ended a Calhoun-determined tour of duty with more respect for Calhoun than he'd had at the beginning. The second was anxious to show up better than the first. Calhoun drilled him in the use of brightness-charts, by which the changes in apparent brightness of stars between overdrive hops could be correlated with angular changes to give a three-dimensional picture of the nearer heavens.
It was a highly necessary art which had not been worked out on Dara, and the prospective astrogators became absorbed in this and other fine points of space-piloting. They'd done enough, in a few trips to Orede, to realize that they needed to know more. Calhoun showed them.
Calhoun did not try to make things easy for them. He was hungry and easily annoyed. It was sound training tactics to be severe, and to phrase all suggestions as commands. He put the four young men in command of the ship in turn, under his direction. He continued to use Weald as a destination, but he set up problems in which the Med Ship came out of overdrive pointing in an unknown direction and with a precessory motion.
He made the third of his students identify Weald in the celestial globe containing hundreds of millions of stars, and get on course in overdrive toward it. The fourth was suddenly required to compute the distance to Weald from such data as he could get from observation, without reference to any records.
By this time the first man was chafing to take a second turn. Calhoun gave each of them a second grueling lesson. He gave them, in fact, a highly condensed but very sound course in the art of travel in space. His young students took command in four-hour watches, with at least one breakout from overdrive in each watch.
He built up enthusiasm in them. They ignored the discomfort of being hungry—though there had been no reason for them to stint on food on Orede—in growing pride in what they came to know.
When Weald was a first-magnitude star, the four were not highly qualified astrogators, to be sure, but they were vastly better spacemen than at the beginning. Inevitably, their attitude toward Calhoun was respectful. He'd been irritable and right. To the young, the combination is impressive.
Maril had served as passenger only. In theory she was to compare Calhoun's lessons with his practice when alone. But he did nothing on this journey which, teaching considered, was different from the two interstellar journeys Maril had made with him.
She occupied the sleeping cabin during two of the six watches of each ship-day. She operated the food-readier, which was almost completely emptied of its original store of food, it having been confiscated by the government of Dara. That amount of food would make no difference to the planet, but it was wise for everyone on Dara to be equally ill-fed.
On the sixth day out from Dara, the sun of Weald had a magnitude of minus five-tenths. The electron telescope could detect its larger planets, especially a gas-giant fifth-orbit world of high albedo. Calhoun had his four students estimate its distance again, pointing out the difference that could be made in breakout position if the Med Ship were mis-aimed by as much as one second of arc.
"And now," he said briskly, "we'll have coffee. I'm going to graduate you as pilots. Maril, four cups of coffee, please."
Murgatroyd said, "Chee?" The Med Ship was badly crowded with six humans and Murgatroyd in a space intended for Calhoun and Murgatroyd alone. The little tormal had spent most of his time in his cubbyhole, watching with beady eyes as so many people moved about on what had been a spacious ship before.
"No coffee for you, Murgatroyd," said Calhoun. "You didn't do your lessons. This is for the graduating class only."
Murgatroyd came out of his miniature den. He found his little cup and offered it insistently, saying, "Chee! Chee! Chee!"
"No!" said Calhoun firmly. He regarded his class of four young men with their blueskin markings. "Drink it down!" he commanded. "That's the last order I'll give you. You're graduate pilots, now!"
They drank the coffee with a flourish. There was not one who did not admire Calhoun for having made them admire themselves. They were, actually, almost as much better pilots as they believed.
"And now," said Calhoun, "I suppose you'll tell me the truth about those boxes you brought on board. You said they were rations, but they haven't been opened in six days. I have an idea what they mean, but you tell me."
The four looked uncomfortable. There was a long pause.
"They could be," said Calhoun detachedly, "cultures to be dumped on Weald. Weald is making plans to wipe out Dara. So some fool has decided to get Weald too busy fighting a plague of its own to bother with you. Is that right?"
The young men stirred unhappily. Young men can very easily be made into fanatics. But they have to be kept stirred up. They can't be provided with sound reason for self-respect. On the Med Ship there'd not been a single reference to Weald except as an object toward which the Med Ship was being astrogated. There'd been no reference to blueskins or enemies or threats or anything but space-piloting. The four young men were now fanatical about the proper handling of a ship in emptiness.
"Well, sir," said one of them, unhappily, "that's what we were ordered to do."
"I object," said Calhoun. "It wouldn't work. I just left Weald a little while back, remember. They've been telling themselves that some day Dara might try that. They've made preparations to fight any imaginable contagion you could drop on them. Every so often somebody claims it's happening. It wouldn't work. I object!"
"But—"
"In fact," said Calhoun, "I forbid it. I shall prevent it. You shan't do anything of the kind."
One of the young men, staring at Calhoun, nodded suddenly. His eyes closed. He jerked his head erect and looked bewildered. A second sank heavily into a chair. He said remotely, "Thish sfunny!" and abruptly went to sleep. The third found his knees giving way. He paid elaborate attention to them, stiffening them. But they yielded like rubber and he went slowly down to the floor. The fourth said thickly and reproachfully, "Thought y'were our frien'!"
He collapsed.
Calhoun very soberly tied them hand and foot and laid them out comfortably on the floor. Maril watched, white-faced, her hand to her throat. Murgatroyd looked agitated. He said anxiously, "Chee? Chee?"
