"In the beginning," he commanded, slowly and thoughtfully, "our people were as yours; they were the same. Our tradition tells that a great breaking of the world took place very many centuries ago. Out of the earth a huge portion was split, and it became as the moon you tell of, only dark. It circled about the earth--"
"By Jove!" cried Stern, and started to his feet. "That dark patch in the sky! That moving mystery we saw nights at the bungalow on the Hudson!"
"You mean--" the girl exclaimed.
"It's a new planetoid! Another satellite of the earth! It's the split-off part of the world!"
"Another satellite?"
"Of course! Hang it, yes! See now? The great explosion that liberated the poisonous gases and killed practically everybody in the world must have gouged this new planet out of the flank of Mother Earth in the latter part of 1920. The ejected portions, millions of millions of tons, hundreds of thousands of cubic miles of solid rock--and with them the ruins of Chicago, Milwaukee, St. Louis, Omaha, and hundreds of smaller cities--are now all revolving in a fixed, regular orbit, some few thousand miles or so from the surface!
"Think! Ours are the only living human eyes that have seen this new world blotting out the stars! This explains everything--the singular changes in the tides and in the direction of the magnetic pole, decreased gravitation and all the other strange things we noticed, but couldn't understand. By Gad! What a discovery!"
The patriarch listened eagerly while Stern and the girl discussed the strange phenomenon; but when their excitement had subsided and they were ready again to hear him, he began anew: "Verily, such was the first result of the great catastrophe. And, as you know, millions died. But among the canyons of the Rocky Mountains--so says the tradition; is it right? Were there such mountains?"
"Yes, yes! Go on!"
"In those canyons a few handfuls of hardy people still survived. Some perished of famine and exposure; some ventured out into the lowlands and died of the gas that still hung heavy there. Some were destroyed in a great fire that the tradition says swept the earth after the explosion. But a few still lived. At one time the number was only eighteen men, twelve women and a few children, so the story goes."
"And then?"
"Then," continued the patriarch, his brow wrinkled in deep thought, "then came the terrible, swift cold. The people, still keeping their English tongue, now dead save for you two, and still with some tools and even a few books, retreated into caves and fissures in the canyons. And so they came to the great descent."
