into a feeling of false security?

"I meant, what are you doing here?" Thulon continued. His eyes went down to the ground.

There was only one shovel on the ground. One shovel was all there had been in the ship. Thulon's glance went to it, went on.

There were three mounds. The soft mould had dug easily. It had all been patted back into place. On the middle mound Ron Val had finished placing a small cross that he had hastily improvised from the ship's stores. Scratched in the metal was a name: Hal Sarkoff.

"We had an outbreak of buboes," Hargraves said. "That's a disease. Three of our companions died and we landed here to bury them. We had just finished doing this when you arrived."

"Died! Three of you died? And you hid them under these mounds?"

"Yes. Of course. There was nothing else we could—"

"You are going to leave them here in the ground!"

"Certainly." Hargraves was wondering if this method of disposing of the dead violated some tribal taboo of this people. Different races disposed of their dead in different ways. He did not know the customs of the inhabitants of this world. "If we have offended against your customs, we are sorry."

"No. There was no offense." Thulon blanketed his thoughts. Hargraves could almost feel the blanket slip into place.

"You came in that ship?" Thulon pointed toward the vessel.

"Yes." It was impossible to conceal this fact.

"Ah." Thulon hesitated, seemed to grope through his mind for the exact shade of expression he wished to convey. Hargraves was aware that the stranger's eyes probed through him, measured him. "It would interest us to examine the vessel. Would you permit this?"

"Certainly." Hargraves knew that Red Nielson jerked startled eyes toward him.

"Jed!" Nielson spoke in protest.

"Shut up!" Hargraves snapped. His body and his mind was a mass of tightly wound springs but his face was calm and his voice was suave. He turned to Thulon. "I will be glad to take you through our ship. However, I do not recommend it."

"No?"

"It might be dangerous, for you and your companions. We have had three cases of buboes, resulting in three deaths. All of us have had shots of immunizing serum and we hope we will have no more cases. However, the germs are unquestionably present in the atmosphere of the ship. Since you probably have no immunity to the disease, to breathe the tainted air would almost certainly result in an attack. This disease is fatal in nine cases out of ten. I therefore suggest you do not enter the ship. In fact," Hargraves concluded, "I was about to say that it might not be wise for you and your companions even to come near us, because of the possibility that you might contract the disease."

Had he gotten the story over it? Was it convincing? Out of the corner of his eyes he saw Ron Val glance at him. When he had said their companions had died of buboes, Ron Val had looked as if he thought he was out of his mind. Now Ron Val understood. "Good going, Jed," his glance seemed to say.

"Hargraves—" This was Nielson speaking. His face was black.

"I suggest," said Jed casually, "that you let me handle this."

Nielson gulped. "Yes. Yes, sir," he said.

Thulon's companions had been paying attention to the conversation. But all the time they were stealing glances at the ship. With half their minds, they seemed to be listening to what was being said. But the other half of their minds was interested in that silent ship hidden under the trees. Were they merely curious, such as any savage might be? Or was this group making a reconnaissance? Hargraves did not know. It did not look like a reconnaissance in force.

"Do you really think we might contract this disease?" Thulon asked.

Hargraves shrugged. "I'm not certain. You might not. It would all depend on the way your bodies reacted to the organism causing the disease."

"Under such circumstances, you show little consideration for our welfare by bringing a plague ship to land here."

"We didn't know you existed. I assure you, however, that if you will remain away from the ship until we have an opportunity to disinfect it thoroughly, any danger to your people will be very slight. On the other hand, if you wish to look our vessel over, to assure yourselves that we are not a menace to you—which we are not—I shall be glad to take you through the ship."

Was he drawing it too fine? He spoke clearly and forcefully. The words, of course, would carry no meaning. But the thought that went along with them would convey what he wanted to say.

"Ah." The thought came from Thulon. "Perhaps—" Again the blanket came over his mind and Hargraves had the impression Thulon was conferring with his companions.

The silent conference ended.

"Perhaps," Thulon said. "It would be better if we returned to visit you tomorrow, or the day after tomorrow."

He bowed. Without another word he and his silent companions turned and began to walk slowly away. Not until he saw the little group slipping away into the dusk did Jed realize he had been holding his breath.

"Hargraves!" Nielson's voice was harsh. "Are you going to let them get away? You fool! That sphere came from this world. Have you forgotten?"

"I have forgotten nothing, I hope."

"But you offered to take them through the ship! They would have seen how badly damaged she is."

"Of course I offered to take them through the ship, then made it impossible for them to accept. We can't stick up 'No Trespassing' signs here. This is their world. We don't know a damned thing about it, or about them. We can't run and we don't want to fight, if we can help it. Furthermore, Nielson, I want you to learn to control your tongue. Remember that in the future, will you?"

For a second, Nielson glared at him. "Yes, sir."

"All right. Go on back to the ship."

Nielson went clumping back toward the vessel. Hargraves turned to Ron Val.

"What do you make of it?"

"I don't know, Jed. There is something about it that I don't like a little bit. They can read minds. Maybe that is what I don't like because I don't know how to react to it. Jed, it may be that we are in great danger here."

"There is little doubt about that," Hargraves answered. "Tonight we will stand watches. Tomorrow we will make a reconnaissance of our own."

Dusk came over the grove. Vega hesitated on the horizon as though trying to make up its mind, then abruptly took the plunge and dived from sight beyond the rim of the world. Night came abruptly, hiding the ship and its occupants. In the sky overhead, stars twinkled like the eyes of watchful wolves.

CHAPTER IV

The Monster

They blacked out the ship before they moved it, carefully covering each port with paper, then showing no lights. Hargraves handled the controls himself, slowly turning current into the drivers so their grunting would not reveal what was happening.

"Are we going to take her up high for tonight?" Ushur, the archeologist asked. "She will fly all right as long as we stay in the atmosphere. We would be safer up high, it seems to me."

"Safer from ground attack, yes," Hargraves said thoughtfully. "However, I'm afraid we would be more exposed to attack from a ship."

"Oh! That damned sphere. I had forgotten about it."

Hargraves moved the ship less than a mile, carefully hid her among the trees. Then he posted guards outside all the ports. He took the first watch himself, in the control room. Ron Val was waiting for him there. The astro-navigator's face was grave. "Jed," he said. "I've been talking to several of the fellows. They don't believe you are taking a sufficiently realistic view of our situation. They don't believe you are facing the facts."

"Um. What facts have I been evading?"

"You apparently don't realize that it will take months—if it can be done at all—to
