"How big are we, Leela? Did he say?" There was no way, here in the lake, by which size could be compared. The exaltation of the ride--its swift, tempestuous movement--the wild, romantic fantasy of it--all this was leaving Frannie. A depression was upon her. She added, "Oh, Leela, Brett did not see us! And Frank--will we ever see them again?" Leela said, "We are about twice normal size--it will not be far to Reaf, swimming like this." In the starlight, Frannie could see that Leela was smiling; a wistful, heavy-hearted smile. She was trying to be brave. And Frannie smiled back. "We mustn't get frightened, Leela. Just watch our chance--try to escape. You stay by me all you can. I mean--when we get"--there was a catch in her voice--"when we get--under the mountains beyond Reaf." Leela nodded. Rokk was calling, and Leela urged her dhrane forward. Soon the left-hand shore and the mountains ahead were visible. The water grew warmer. Small islands appeared. The dhranes panted with the heat of the water; in the muddy channels between the islands, sometimes they floundered. Steam was in the air; ahead it lay like a bank of fog, with the frowning mountains rising above it. Presently, through the fog, the houses of Reaf came into view. Small ghostly outlines of houses on stilts. To the right of them was a yawning black mouth where one of the rivers plunged into the mountain. The turgid current was swinging that way; Rokk urged the dhrane across it, to the left. Soon they were swimming among the houses. These seemed very small. Frannie reached up from the dhrane's back and laid her hand on the roof of one as she passed it. Rokk was heading inshore. The mountain here was a frowning cliff-face, with a very narrow ledge at the water level. The ledge ended in a wooden incline bridge leading upward to a group of buildings near shore. Six or eight small houses with doors and rectangles of windows, clustered there together, perched on stiff wooden legs over the water. The incline bridge connected them with the shore, and they were strung together by a broad wooden platform. Rokk shouted, and from behind the buildings a giant appeared. He had been sitting in the water. He stood up, with mud and slime dripping from him. A man, like Rokk, but younger. His hair was sleek and black, and fell long to his bared chest, across which a skin was draped. His face was broad and flat, and hairless. He stood with the water to his knees, beside the buildings with his arm arched over their roofs as he leaned against them. He smiled. He called, "_Ae_, Rokk!" And Rokk answered, "_Ae_, Degg." They spoke together. Then they spoke in Leela's language. Leela murmured to Frannie, "This man Degg is to remain here until we are safely above." Rokk issued his commands. Degg sat down again in the water, waist-deep, with his arms holding his hunched-up knees. He yawned and waved his hand as Rokk swam his dhrane away.
