least an hour, two if possible, on the thirty-foot yawl that had already begun to take satisfactory shape on the timber ways which now stood on the river bank.
All through July and part of August he labored on this boat, building it stanch and true, calking it thoroughly, fitting a cabin, stepping a fir mast, and making all ready for the great migration which he felt must inevitably be forced upon them by the arrival of cool weather.
He doubted very much, in view of the semitropic character of some of the foliage, whether even in January the temperature would now go below freezing; but in any event he foresaw that there would be no fruits available, and he objected to a winter on flesh foods. In preparation for the trip he had built a little “smoke-house” near the beach, and here he smoked considerable quantities of meat--deer-meat, beef from a wild steer which he was so fortunate as to shoot during the third week of their stay at the bungalow, and a good score of hams from the wild pigs which rooted now and then among the beech growth half a mile downstream.
Often the girl and he discussed this coming trip, of an evening, sitting together by the river to watch the stars and moon and that strange black wandering blotch that now and then obscured a portion of the night sky--or perchance leaning back in their huge, rustic easy chairs lined with furs on the broad piazza; or again, if the night were cool or rainy, in front of their blazing fire of pine knots and driftwood, which burned with gorgeous blues and greens and crimsons in the vast throat of Hope Lodge fireplace.
Other matters, too, they talked of--strange speculations, impossible to solve, yet filling them with vague uneasiness, with wonder and a kind of mighty awe in face of the vast, unknowable mysteries surrounding them; the forces and phenomena which might, though friendly in their outward aspect, at any time precipitate catastrophe, ruin and death upon them and extinguish in their persons all hopes of a world reborn.
The haunting thought was never very far away: “Should either one of us be killed--what then?”
One day Stern voiced his fear.
“Beatrice,” he said, “if anything should ever happen to me, and you be left alone in a world which, without me, would become instantly hostile and impossible, remember that the most scientific way out is a bullet. That's
She nodded, and for a long time that day the silence of a great pact weighed upon their souls.
CHAPTER IX. PLANNING THE GREAT MIGRATION
Stern rigged a tripod for the powerful field-glasses he had rescued from the Metropolitan Building, and by an ingenious addition of a wooden tube and another lens carefully ground out of rock crystal, succeeded in producing (on the right-hand barrel of the binoculars) a telescope of reasonably high power. With this, of an evening, he often made long observations, after which he would spend hours figuring all over many sheets of the birch bark, which he then carefully saved and bound up with leather strings for future reference.
In Van's set of encyclopedias he found a fairly large celestial map and thorough astronomic data. The results of his computations were of vital interest to him.
He said to Beatrice one evening:
“Do you know, that wandering black patch in the sky moves in a regular orbit of its own? It's a solid body, dark, irregular in outline, and certainly not over five hundred miles above the surface of the earth.”
“What can it be, dear?”
“I don't know yet. It puzzles me tremendously. Now, if it would only appear in the daytime once in a while, we might be able to get some information or knowledge about it; but, coming only at night, all it records itself as is just a black, moving thing. I'm working on the size of it now, making some careful studies. In a while I shall probably know its area and mass and density. But what it is I cannot say--not yet.”
They both pondered a while, absorbed in wonder. At last the engineer spoke again.
“Beta,” said he, “there's another curious fact to note. The axis of the earth itself has shifted more than six degrees, thirty minutes!”
“It has? Well--what about it?” And she went on with her platting of reed cordage.
“You don't seem much concerned about it!”
“I'm not. Not in the least. It can shift all it wants to, for all of me. What hurt does it do? Doesn't it run just as well that way?”
Stern looked at her a moment, then laughed.
“Oh, yes; it runs all right,” he answered. “Only I thought the announcement that the pole-star had thrown up its job might startle you a bit. But I see it doesn't. So far as practical results go, it accounts for the warmer climate and the decreased inclination to the plane of the ecliptic; or, rather, the decreased--”
“Please, please, don't!” she begged. “There's nothing really wrong, is there?”
“Well, that depends on how you define it. Probably an astronomer might think there was something very much wrong. I make it that the orbit of the earth has altered its relative length and width by--”
“No figures, Allan, there's a dear. You know I'm awfully bad at arithmetic. Tell me what it means, won't you?”
“Well, it means, for one thing, that we've maybe spent a far longer time on this earth since the cataclysm than we even dare suspect. It may be that what we've been calculating as about a thousand years, is twice that, or even five times that--no telling. For another thing, I'm convinced by all these changes, and by the diminution of gravity and by the accelerated rate of revolution of the earth--”
“Allan dear, please hand me those scissors, won't you?”
Stern laughed again.
“Here!” said he. “I guess I'm not much good as a lecturer. But I tell you one thing I'm going to do, and that's a one best bet. I'm going to have a try at some really big telescope before a year's out, and know the truth of this thing!”
“A big telescope! Build one, you mean?”
“Not necessarily. All I need is a chance to make some accurate observations, and I can find out all I need to know. Even though I have been out of college for--let's see--”
“Fifteen hundred years, at a guess,” she suggested.
“Yes, all of that. Even so, I remember a good bit of astronomy. And I've got my mind set on peeking through a first-class tube. If the earth has broken in two, or anything like that, and our part is skyhooting away toward the unknown regions of outer space beyond the great ring of the Milky Way and is getting into an unchartered place in the universe--as it seems to be--why, we ought to have a good look at things. We ought to know what's what, eh?
“Then there's the moon I want to investigate, too. No living man except myself has even seen the side that's now turned toward the earth. No telling what a good glass mightn't show.”
“That's so, dear,” she answered. “But where can you find the sort of telescope you need?”
“In Boston--in Cambridge, rather. The Harvard observatory has the biggest one within striking distance. What do you say to our making our trial trip in the boat, up the Sound and around Cape Cod, to Boston? We can spend a week there, then slant away for wherever we may decide to pass the winter. How does that suit you, Beta?”
She put away her work, and for a moment sat looking in at the flames that went leaping up the huge boulder chimney. The room glowed with warmth and light that drove away the cheerlessness of a foggy, late August drizzle.
“Do you really think we're wise to--to leave our home, with winter coming on?” she asked at length, pensively, the firelight casting its glow across her cheek and glinting in her eyes.
“Wise? Yes. We can't stay here, that's certain. And what is there to fear out in the world? With our firearms and our knowledge of fire itself, our science and our human intelligence, we're far more than a match for all enemies, whether of the beast-world or of that race of the Horde. I hate, in a way, to revisit the ruins of New York, for more ammunition and canned stuffs. The place is to o ghastly, too hideous, now, after the big fight.
“Boston will be a clean ground for us, with infinite resources. And as I said before, there's the Cambridge observatory. It's only two or three miles back in the forest, from the coast; maybe not more than half a mile from some part of the Charles River. We can sail up, camp on Soldiers' Field, and visit it easily. Why not?”
He sat down on the tiger-rug before the fire, near the girl. She drew his head down into her lap; then, when
