The springs came a little earlier each year, the falls a little later, and the observations showed the suns progressing steadily northward. But the winters, though shorter, were seemingly as cold as ever. The long summers reached such a degree of heat on the ninth year that Lake knew they could endure no more than two or three years more of the increasing heat.
Then, in the summer of the tenth year, the tilting of Ragnarok—the apparent northward progress of the suns—stopped. They were in the middle of what Craig had called Big Summer and they could endure it—just barely. They would not have to leave the caves.
The suns started their drift southward. The observations were continued and carefully recorded. Big Fall was coming and behind it would be Big Winter.
Big Winter ... the threat of it worried Lake. How far to the south would the suns go—how long would they stay? Would the time come when the plateau would be buried under hundreds of feet of snow and the caves enclosed in glacial ice?
There was no way he could ever know or even guess. Only those of the future would ever know.
On the twelfth year only Lake and West were left of the Old Ones. By then there were eighty-three left of the Young Ones, eight Ragnarok-born children of the Old Ones and four Ragnarok-born children of the Young Ones. Not counting himself and West, there were ninety-five of them.
It was not many to be the beginnings of a race that would face an ice age of unknown proportions and have over them, always, the threat of a chance return of the Gerns.
The winter of the fifteenth year came and he was truly alone, the last of the Old Ones. White-haired and aged far beyond his years, he was still leader. But that winter he could do little other than sit by his fire and feel the gravity dragging at his heart. He knew, long before spring, that it was time he chose his successor.
He had hoped to live to see his son take his place—but Jim was only thirteen. Among the others was one he had been watching since the day he told Craig he [p. 68] would find metals to build a ship and kill the Gerns: Bill Humbolt.
Bill Humbolt was not the oldest among those who would make leaders but he was the most versatile of them all, the most thoughtful and stubbornly determined. He reminded Lake of that fierce old man who had been his grandfather and had it not been for the scars that twisted his face into grim ugliness he would have looked much like him.
