No one answered him. Nor did anyone else mention their last venture near the Scour Sea.
"Why are we heading west now?" asked Elemak. "We've gone barely half the length of the Valley of Fires - the caravan trail doesn't come to the sea again until it reaches the Sea of Fire, due south of here. All we're doing is going far out of our way to the west."
"There are rivers to the west," said Volemak.
"No there aren't," said Elemak. "If there were, the caravanners through here would have found them and used them. There'd be cities there."
"Nevertheless," said Volemak, "we're going west. The Oversoul says that we'll need to make a long camp again - to plant crops, to harvest them."
"Why?" asked Mebbekew. "We're making good progress. The babies are all thriving well. Why another camp?"
"Because Shedemei is pregnant, of course," said Volemak, "and getting sicker with each passing day."
They all looked at Shedemei in surprise. She blushed - and looked no less surprised than the others. "I only began to suspect it myself this morning," she said. "How can the Oversoul know what I'm only guessing at?"
Volemak shrugged. "He knows what he knows."
"Pretty poor timing, Shedya," said Elemak. "All the other women are holding off on pregnancy because they're nursing, but now we have to wait for you."
For once Zdorab spoke up sharply. "Some things can't be timed precisely, Elya, so don't lay blame where there was no volition."
Elemak looked at him steadily. "I never do," he said. But then he dropped the matter and set out to the west, blazing a trail for the caravan.
Their route led up into real mountains - volcanic ones, with some relatively recent lava flows that had not yet been broken into soil. Issib used the Index to come up with information about the area - there were at least fifty active and dormant volcanos in this range of mountains fronting on the Scour Sea. "The last eruption was only last year," he said, "but much farther to the south."
"Which may be the reason the Oversoul is sending us to the sea this far north," said Volemak.
Hard as the climb was, coming down the other side of the mountain range was harder - it was steeper and more heavily overgrown. Indeed, it was almost a jungle high on the slopes of the mountain.
"The winter winds come off the sea," said Issib, "and there are squalls almost every day in summer, too. The mountains catch the clouds, force them up into the colder atmosphere, and bring down whatever moisture is in them. So it's a rain forest here in the mountains. It won't be as wet down by the sea." They were becoming used to Issib being the one who explored the Index; during days of travel, he was the only one with no other duties, and he carried the Index with him, one hand constantly on it, exploring. Zdorab had shown him so many tricks and back doors that he was almost as deft now as the librarian himself. And no one disparaged the value of the information Issib provided, because it was all he could provide.
They were in the middle of a tricky passage down a tangled ravine when they felt an earthquake -rather a violent one, which threw two of the camels off their feet and set the others to stamping and turning in confusion.
"Out of the ravine!" cried Issib at once.
"Out? How?" answered Volemak.
"Any way we can!" shouted Issib. "The Index says that this earthquake jarred loose a lake high up in the mountains - anything in the ravine is going to be swept away!"
It was a particularly bad time for an emergency - Elemak and Vas were far ahead, blazing a trail, and Nafai and Obring were hunting higher up in the mountain. But Volemak had been journeying far longer than Elemak, and had resources of his own. He quickly sized up the walls of the ravine and chose a route up through a jumble of rocks into a side canyon that might lead to the top. "I'll lead the way," he said, "because I'm the one who knows best what camels can do. Luet, you bring the women and children along - Meb, you and Zdorab herd the pack animals after us. Supplies first, cold- and dryboxes last. Issib, you stay within earshot of them, and stay in touch with the Index. Tell them when there's no more time. When they have
