Gaining speed, it passed over their heads. They caught another glimpse of it as it passed over an opening in the branches of the trees. Then it was gone, the throb of the drivers dying quickly away.

"Nielson will come back for us." Noble's voice, usually poised and assured, was garbled. "He'll return and pick us up. He won't leave us here."

"He had some reason for taking off," Hargraves heard himself saying. "He'll come back. He has to." Subconsciously he knew that this, at the very best, was wishful thinking.

The ship had no more than vanished until another sound came to their ears, that of men shouting. A group came into sight among the trees, following along the ground the course the ship had taken through the air.

"They're our fellows!" Hargraves heard Noble gasp.

"What happened?" the captain demanded, as the group approached.

Nielson was in the lead. There was a bruise on his cheek and his right eye was already beginning to turn black. "I'll tell you what happened!" he said savagely. "Sarkoff and Ron Val took over the ship, that's what happened!"

"Ron Val!"

"That's what I said. Ron Val was helping him. They pulled guns. Before we knew what was happening, they had herded us together and were shoving us outside. I tried to stop it and Sarkoff took a poke at me."

"It wasn't really Sarkoff, then?" Noble whispered.

"Any damned fool would have known that!" Nielson answered. He spoke to the bio-chemist but his eyes were on Hargraves. "I'm going to repeat that, so there won't be any misunderstanding of my meaning. Any damned fool would have known that a dead man doesn't get up out of his grave and come to life again. Except you, Hargraves. You always were a sucker for fairy stories."

Jed Hargraves winced with every word that was spoken. They kept on coming.

"You ought to have known that thing wasn't Hal Sarkoff. Any man in his right senses would have known it instantly. Any man fit to command would have taken measures to meet the situation, either by destroying that thing, or locking it up. But you were running things, Hargraves. You were in charge. And you had to sit back and think before you would act. You had to make sure you were right, before you went ahead. Your negligence, Hargraves, cost us our only chance of ever returning home."

Nielson's voice was harsh with anger. And—Hargraves recognized the bitter truth—every word Nielson uttered was correct. Whatever the thing was that had come to the ship, he should have recognized it as a source of danger. He had so recognized it. But he had not acted.

"I—"

"Shut up!" Nielson snapped. "According to our agreement, any time you are shown to be unfit to command, you may be removed by a vote of the majority. There is no question but that you have shown yourself unfit to be in charge of this expedition."

No time was wasted in reaching a decision. To Nielson's question as to whether Hargraves should be removed from command, there was a chorus of "Ayes."

"No," said one voice. It was Usher, the archeologist.

"State your objection," Nielson rasped.

"The old one about changing horses in mid-stream," the archeologist answered. "Also the old one about not jumping to conclusions before all the evidence is in."

"What evidence isn't in?"

"We don't know why Ron Val joined Sarkoff," the archeologist answered.

"What difference does that make? We don't even know that Ron Val was still himself. The thing that looked like Ron Val might have been another monstrosity like Sarkoff."

"So it might," the archeologist shrugged. "Anyhow my vote is not important. I'm just putting it in for the sake of the record, if there ever is a record. I would also like to mention that if ever we needed discipline and unity, now is the time."

"We will have discipline, I promise you," Nielson said. "Hargraves, you are removed from command, understand?"

"Yes," said Hargraves steadily.

Only one ballot was needed to put Nielson in charge.

"All right," said Ushur to the new captain. "You're the boss now. We're all behind you. What are you going to do?"

"Do? I—" Nielson looked startled. He glanced at Hargraves.

The former captain sighed. It was easy enough to elect a new leader. Vehemently he wished that all problems could be solved so easily.

"I suggest," he said, "—and this is only a suggestion—that we attempt to find the ship, and if possible, to regain possession of her. She is the only tool we have to work with."

"That is exactly what I was going to say," Nielson said emphatically. "Find the ship."

To give him credit, he set about the job in a workmanlike manner, sending two scouts ahead of the main group, throwing out a scout on each flank. The only way they could hope to find the ship was by following the course it had taken through the air. Since Sarkoff, in taking over the vessel, had not disarmed them, each possessed a vibration pistol. In a fight against ordinary enemies they would be able to give a good account of themselves. But would any enemy they met likely be ordinary?

Hargraves drew Usher aside. "I would like to talk to you," he said. "What actually happened when the ship was taken?"

"I don't know, Jed," the archeologist ruefully answered. "I was in my cabin. The first thing I knew I heard a hell of a hullabaloo going on up in the control room. I dashed up there to see what was going on."

"What was happening?"

"Nielson, Rodney, Turner, and a couple of others were there. So were—well, they looked like Sarkoff and Ron Val. Nielson was getting up off the floor. Sarkoff and Ron Val had both drawn their guns and were covering the group. When I came charging in, Sarkoff covered me. Before I could recover from my surprise, he and Ron Val had kicked every one of us out of the ship. Then they took off." The archeologist shook his shaggy head.

"Ron Val was helping?"

"No question about it. Which means, of course, that he was either under some subtle form of hypnosis, or it wasn't Ron Val. I would bet my life on his loyalty."

"So would I," said Hargraves. And the memory came back of how thrilled Ron Val had been at the prospect of landing on this, world. "It would mean a lot to find people here. We could exchange experiences, learn a lot," Ron Val had said, his face glowing at the thought. All the others had felt the same way. The Third Interstellar Expedition had no military ambitions. It was not bent on conquest. The solar system had outgrown military expeditions, war, and the thought of war, and cruisers went out from it not to fight but to learn. Knowledge was the thing they sought, all knowledge, so the human race could determine its place in the cosmos, could know the history of all things past, could possibly forecast the shape of things to come.

The landing of the Third Interstellar Expedition on this Vegan world had been a part of a vast evolution, a march that, starting on earth so long ago that all history of it was forever lost, was now reaching out across the cosmos. A new evolution! Ron Val had always been talking about this new evolution. It was one of his favorite subjects.
