Perplexed, he went back to his work again. And though he tried to banish the puzzle from his mind it still continued to haunt and to annoy him.
Each day brought new and interesting activities. Now they made an expedition to gather a certain kind of reeds which Beatrice could plat into cordage and basketry; now they peeled quantities of birch-bark, which on rainy days they occupied themselves in splitting into thin sheets for paper. Stern manufactured a very excellent ink in his improvised laboratory on the second floor, and the split and pointed quills of a wild goose served them for pens in taking notes and recording their experiences.
“Paper will come later, when we've got things a little more settled,” he told her. “But for now this will have to do.”
“I guess if you can get along with skin clothing for a while, I can do with birch-bark for my correspondence,” she replied laughing. “Why not catch some of those wild sheep that seem so plentiful on the hills to westward? If we could domesticate them, that would mean wool and yarn and cloth--and milk, too, wouldn't it? And if milk, why not butter?”
“Not so fast!” he interposed. “Just wait a while--we'll have cattle, goats, and sheep, and the whole business in due time; but how much can one pair of human beings undertake? For the present we'll have to be content with what mutton-chops and steaks and hams I can get with a gun--and we're mighty lucky to have those!”
Singularly enough, and contrary to all beliefs, they felt no need of salt. Evidently the natural salts in their meat and in the fruits they ate supplied their wants. And this was fortunate, because the quest of salt might have been difficult; they might even had had to boil sea-water to obtain it.
They felt no craving for sweets, either; but when one day they came upon a bee-tree about three-quarters of a mile back in the woods to westward of the river, and when Stern smoked out the bees and gathered five pounds of honey in the closely platted rush basket lined with leaves, which they always carried for miscellaneous treasure-trove, they found the flavor delicious. They decided to add honey to their menu, and thereafter always kept it in a big pottery jar in their kitchen.
Stern's hunting, fishing and gardening did not occupy his whole time. Every day he made it a rule to work at 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 my way if anything happens to you! Understand?”
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--”
