And now the chief took a strange object from his grail and held a glowing wire to its tip, and smoke came from it and from the pygmy's mouth. Joe jumped at the first puff; his fellows scattered for the foothills again. Joe wondered if the noseless pygmies could be the brood of the dragon. Perhaps her children took this larval form, but, like their mother, they could breathe out fire and smoke?

"But I ain't a dummy," Joe said. "It didn't take me long to figure out that the thmoke came from the obchect, vhich in Englith ith a thigar. Their chief made it plain that if I'd get on the thyip, I could thmoke the thigar. Now, I mutht've been crathy to do tho, but I vanted to thmoke that thigar. Maybe I thought I'd impreth my tribe, I don't know."

He jumped on the ship, his weight causing it to tilt a little on the port. He swung his grail to show them that if they attacked him, he would bash their skulls in with it. They took the hint and did not come close. The chief gave Joe a cigar, and though Joe coughed a little and found the taste of tobacco strange, he liked it. Moreover, when he had drunk beer for the first time, he was entranced.

So Joe decided to go on the Riversnake's back up The River with the pygmies. He was put to work on a mighty sweep, and he was called Tehuti. 'Tehuti?" von Richthofen said.

"The Greek form is Thoth," Clemens said. "To the Egyptians, he looked something like the long-beaked ibisgod. I suppose he must also have reminded them of the baboon-god, Bast, but that tremendous nose outweighed that consideration. So, Thoth, or Tehuti, he became."

Days and nights flowed by like The River. Sometimes, Joe became tired and wished to be put ashore. By now, he could speak the pygmies' language, though haltingly. The chief would agree to do as Joe wished since it was obvious that any denial might result in the slaughter of his entire crew. But he would speak sadly of Tehuti's education ending there, just when he was doing so well. He had been a brute, though with the face of the god of wisdom, and soon he would be a man. Brute? God? Man? What were they?

The order was not quite right, the chief would say. The correct sequence, ever upward, was brute, man and god. Yet it was true you might see a god disguised as a beast, and man merged insensibly from animal into deity, balanced between the two, and now and then changed into one or the other.

That was beyond the breadloaf-shaped brain of Tehuti. He would squat and scowl at the nearing bank. There would be no more cigars or beer. The people on the bank were his kind, but they were also not his tribe, and they might kill him. Moreover, he was beginning for the first time to experience intellectual stimulation, and that would cease once he was back among the titanthrops.

So he would look at the chief and blink, grin and shake his head and tell him he was going to stay on the ship. He took his turn at the sweep and resumed his study of the most marvelous of all things: a tongue that knew philosophy. He became fluent in their speech and began to grasp the wonderful things the leader told him, although sometimes it was as painful as grasping a handful of thorns. If this or that idea eluded him, he pursued it, caught it, swallowed it, perhaps vomited it up a score of times. Eventually, he digested it and got some nourishment from it.

The River flowed by. They rowed, always staying close to the shore, where the current was weakest. Days and nights, and now the sun did not climb so high in the heavens but was a little lower at its zenith than it had been the week before. And the air grew colder.

Sam said, "Joe and his party were getting close to the north pole. The inclination of this planet's equator to the plane of the ecliptic is zero. As you know, there are no seasons; day and night are equal in length. But Joe was approaching the point where he would see the sun always half below the horizon and half above. Or would have if it hadn't been for the mountains."

"Yeth. It vath alvayth tvilight. I got cold, though not ath cold ath the men. They vere thyivering their atheth off."

"His big bulk radiates heat slower than our puny bodies," Clemens said.

"Pleathe, pleathe! Thyould I talk or jutht keep my big mouth thyut?" Lothar and Sam grinned at him.

He continued. The wind grew stronger, and the air became misty. He began to get uneasy. He wanted to turn back, but by now he did not want to lose the respect of the leader. He would go every inch of the way toward their unknown goal with them. "You didn't know where they were going?" Lothar said. "Not egthactly. They vanted to get to the headvaterth of the River. They thought maybe the godth lived there, and there the godth vould admit them into the true aftervorld. They thaid that thith vorld vathn't the true vorld. It vath a thtage on the vay to the true vorld. Vhatever that ith."

One day, Joe heard a rumble that sounded as faintly but yet as near as gas moving within his bowels. After a while, as the noise became like thunder, he knew it was water falling from immense heights.

The ship swung into a bay protected by a finger of land. The grailstones no longer lined The River. The men would have to catch fish and dry them. There was also a store of bamboo tips on the ship; these had been collected in the sunlit region for just such an eventuality.

The leader and his men prayed, and the party began climbing a series of cataracts. Here the superhuman strength of Tehuti-Joe Miller helped them in overcoming obstacles. Other times, his great weight was a hindrance and a danger.

Upward they went, wet because of the everpresent spray. When they came to a cliff smooth as ice for a thousand feet up, they despaired. Reconnoitering, they found a rope dangling from the face of a cliff. It was formed to towels tied together. Joe tested its strength and climbed up, hand over hand, his feet braced against the cliff, until he reached the top. There he turned to watch the others follow him. The chief, first after Joe, tried much easier, and halfway up to the top he could go no farther. Joe pulled him and the extremely heavy weight of the rope to the top. He did the same for each man in the party.

"Where in hell did the rope come from?" von Richthofen said.

"Someone had prepared the way for them," Clemens said. "Given the primitive technology of this planet, no one could have found a way to get that rope up to the rock around which one end of the rope was tied. Maybe a balloon might have lifted a man up there. You could make a balloon of Riverdragonskin or human skins, you know. You could make hydrogen by passing steam over highly heated charcoal in the presence of a suitable catalyst. But in this world of scarce metal, where's the catalyst?

"Hydrogen could be made without a catalyst but at an enormous cost in fuel. But there was no evidence of the furnaces needed to make the hydrogen. Besides, why would the towels be left behind, when they'd be needed again? No, some unknown person, let's call him The Mysterious Stranger, put that rope there for Joe and party. Or for whoever might come along. Don't ask me who he was or how he did it. Listen. There's more."

The party, carrying the rope, walked for several miles in the mist-ridden twilight on a plateau. They came to another cliff where The River broadened out above them into a cataract. It was so wide, it seemed to Joe that there was enough water to float the moon of Earth upon it. He would not have been surprised to see that great silver-andblack orb appear on the brink of the cataract far above and hurtle down that thunder of waters and be smashed to pieces on the rocks in the maelstrom foot.

The wind became stronger and louder; the mist, thicker. Drops of water condensed on the towels they had now fastened around themselves from head to foot. The cliff before them was as mirror-smooth and perpendicular as the one just ascended. Its top was lost in the fog; it could be only fifty feet high or could be ten thousand. They searched along the foot, hoping for some kind of fissured And they found one. It was like a small door at the juncture of plateau and cliff. It was so low, it forced them to get down on hands and knees and crawl. Joe's shoulders rubbed against the sides of the rock. But the rock was smooth, as if the hole had been made by man and rubbed until all roughness was gone.
