Jim did not answer but kicked at a trembling leg of the beast. "The filthy, filthy thing!" he said intensely. "Cripes, how I hate them. I wish I could burn every one on Mars, all at once." He walked on up along the body, located the egg sac, and carefully blasted every bit of it.

Willis had not moved. He was sobbing quietly. Jim came back, picked him up, and popped him in the travel bag. "Let's stick together from here on," he said. "If you don't feel like climbing, I'll go around."

"Okay."

"Frank!"

"Uh? Yes, what is it, Jim?" Frank's voice was listless.

"What do you see ahead?"

"Ahead?" Frank tried manfully to make his eyes focus, to chase the fuzz from them. "Uhh, it's the canal, the green belt I mean. I guess we made it."

"And what else? Don't you see a tower?"

"What? Where? Oh, thereYes, I guess I do. It's a tower all right."

"Well, for heaven's sake, don't you know what that means? Martians!"

"Yeah, I suppose so."

"Well, show some enthusiasm!"

"Why should I?"

"They'll take us in, man! Martians are good people; you'll have a warm place to rest, before we go on."

Frank looked a bit more interested, but said nothing. "They might even know Gekko," Jim went on. "This is a real break."

"Yeah, maybe so."

It took another hour of foot-slogging before the little Martian town was reached. It was so small that it boasted only one tower, but to Jim it was even more beautiful than Syrtis Major. They followed its wall and presently found a gate.

They had not been inside more than a few minutes when Jim's hopes, so high, were almost as low as they could be. Even before he saw the weed-choked central garden, the empty walks and silent courts had told him the bad truth: the little town was deserted.

Mars must once have held a larger native population than it does today. Ghost cities are not unknown and even the greater centers of population, such as Charax, Syrtis Major and Minor, and Hesperidum, have areas which are no longer used and through which tourists from Earth may sometimes be conducted. This little town, apparently never of great importance, might have been abandoned before Noah laid the keel of his ship.

Jim paused in the plaza, unwilling to speak. Frank stopped and sat down a metal slab, its burnished face bright with characters that an Earthly scholar would have given an arm to read. "Well," said Jim, "rest a bit, then I guess we had better find a way to get down onto the canal."

Frank answered dully, "Not for me. I've come as far as I can."

"Don't talk that way."

"I'm telling you, Jim, that's how it is."

Jim puzzled at it. "I tell you what-I'll search around. These places are always honeycombed underneath. I'll find a place for us to hole up over night."

"Just as you like."

"You just stay here." He started to leave, then suddenly became aware that Willis was not with him. He then recalled that the bouncer had jumped down when they entred the city. "Willis-where's Willis?"

"How would I know?"

"I've got to find him. Oh, Willis! Hey, Willis! Come, boy!" His voice echoed around the dead square.

"Hi, Jim!"

It was Willis, rightly enough, his voice reaching Jim from some distance. Presently he came into sight. But he was not alone; he was being carried by a Martian.

The Martian came near them, dropped his third leg, and leaned down. His voice boomed gently at Jim. "What's he saying, Frank?"

"Huh? Oh, I don't know. Tell him to go away."

The Martian spoke again. Jim abandoned the attempt to use Frank as a translator and concentrated on trying to understand. He spotted the question symbol, in the inverted position; the remark was an invitation or a suggestion of some sort. Following it was the operator of motion coupled with some radical that meant nothing to Jim.

He answered it with the question symbol alone, hoping that the native would repeat himself. Willis answered instead. "Come along, Jim boy-fine place!"

Why not? he said to himself and answered, "Okay, Willis." To the Martian he replied with the symbol of general assent, racking his throat to produce the unEarthly triple guttural required. The Martian repeated it, inverted, then picked up the leg closest to them and walked rapidly away without turning around. He had gone about twenty-five yards when he seemed to notice that he was not being followed. He backed up just as rapidly and used the general inquiry symbol in the sense of "What's wrong?"

"Willis," Jim said urgently, "I want him to carry Frank."

"Cany Frank boy?"

"Yes, the way Gekko carried him."

"Gekko not here. This K'boomch."

"His name is K'boomk?"

"Sure-K'boomch," Willis agreed, correcting Jim's pronunciation.

"Well, I want K'boomch to carry Frank like Gekko carried him."

Willis and the Martian mooed and croaked at each other for a moment, then Willis said, "K'boomch wants to know does Jim boy know Gekko."

"Tell him we are friends, water friends."

"Willis already tell him."

"How about Frank?" But it appeared that Willis had already told his new acquaintance about that, too, for K'boomch enlosed Frank in two palm flaps and lifted him up. Frank opened his eyes, then closed them. He seemed indifferent to what happened to him.

Jim trotted after the Martian, stopping only to grab up Frank's skates from where he had abandoned them on the metal slab. The Martian led him into a huge building that seemed even larger inside than out, so richly illuminated in glowing lights were the walls. The Martian did not tarry but went directly into an archway in the far wall; it was a ramp tunnel entrance, leading down.

The Martians appear never to have invented stair steps, or more likely never needed them. The low surface gravity of Mars, only 38% of that of Earth, permits the use of ramps which would be disastrously steep on Earth. The Martian led Jim down a long sequence of these rapid descents.

Presently Jim discovered, as he had once before under Cynia city, that the air pressure had increased. He raised his mask with a feeling of great relief; he had not had it off for more than twenty-four hours. The change in pressure had come abruptly; he knew from this that it had not resulted from descent alone, nor had they come deep enough to make any great difference in pressure.

Jim wondered how the trick was accomplished. He decided that it had pressure locks beat all hollow.

They left the ramps and entered a large domed chamber, evenly lighted from the ceiling itself. Its walls were a continuous series of archways. K'boomch stopped and spoke again to Jim, another inquiry in which he used the name Gekko.

Jim reached into his memory and carefully phrased a simple declaration: "Gekko and I have shared water. We are friends."

The Martian seemed satisfied; he led the way into one of the side rooms and placed Frank gently on the floor. The door closed behind them, sliding silently into place. It was a smallish room, for Martians, and contained several resting frames. K'boomch arranged his ungainly figure on one of them.

Suddenly Jim felt heavy and sat down rather unexpectedly on the floor. The feeling persisted and with it a slight giddiness; he stayed seated. "Are you all right, Frank?" he asked.

Frank muttered something. His breathing seemed labored and rough, Jim took off Frank's mask and touched his face; it was hot.

There was nothing that he could do for Frank at the moment. The heavy feeling continued. The Martian did not seemed disposed to talk and Jim did not feel up to attempting a conversation in the dominant tongue in any case. Willis had withdrawn into a ball. Jim lay down beside Frank, closed his eyes, and tried not to think.

He felt a moment of lightness, almost of vertigo, then felt heavy again and wondered what he was coming down with. He lay still for a few more minutes, to be disturbed presently by the native bending over him and speaking. He sat up and discovered that he felt fine again. K'boomch scooped up Frank and they left the room.
