"The good old star has certainly shifted out of place a bit.

Furthermore, I've been observing certain evolutionary changes in the animals and plants about us. Those have helped, too."

"And--and what have you found out?" asked she with tremulous interest.

"Well, I think I've got the answer, more or less correctly. Of course it's only an approximate result, as we say in engineering. But the different items check up with some degree of consistency.

"And I'm safe in believing I'm within at least a hundred years of the date one way or the other. Not a bad factor of safety, that, with my limited means of working."

The girl's eyes widened. From her hand fell the empty gold cup; it rolled away across the clean-swept floor.

"What?" cried she. "You've got it, within a hundred years! Why, then--you mean it's _more_ than a hundred?"

Indulgently the engineer smiled.

"Come, now," he coaxed. "Just guess, for instance, how old you really are--and growing younger every day?"

"Two hundred maybe? Oh surely not as old as that! It's horrible to think of!"

"Listen," bade he. "If I count your twenty-four years, when you went to sleep, you're now--"

"What?"

"You're now at the very minimum calculation, just about one thousand and twenty-four! Some age, that, eh?"

Then, as she stared at him wide-eyed he added with a smile.

"No disputing that fact, no dodging it. The thing's as certain as that you're now the most beautiful woman in the whole wide world!"

CHAPTER XII

DRAWING TOGETHER

Days pa.s.sed, busy days, full of hard labor and achievement, rich in experience and learning, in happiness, in dreams of what the future might yet bring.

Beatrice made and finished a considerable wardrobe of garments for them both. These, when the fur had been clipped close with the scissors, were not oppressively warm, and, even though on some days a bit uncomfortable, the man and woman tolerated them because they had no others.

Plenty of bathing and good food put them in splendid physical condition, to which their active exercise contributed much. And thus, judging partly by the state of the foliage, partly by the height of the sun, which Stern determined with considerable accuracy by means of a simple, home-made quadrant--they knew mid-May was past and June was drawing near.

The housekeeping by no means took up all the girl's time. Often she went out with him on what he called his "pirating expeditions," that now sometimes led them as far afield as the sad ruins of the wharves and piers, or to the stark desolation and wreckage of lower Broadway and the onetime busy hives of newspaperdom, or up to Central Park or to the great remains of the two railroad terminals.

These two places, the former tide-gates of the city's life, impressed Stern most painfully of anything. The disintegrated tracks, the jumbled remains of locomotives and luxurious Pullmans with weeds growing rank upon them, the sunlight beating down through the caved-in roof of the Pennsylvania station "concourse," where millions of human beings once had trod in all the haste of men's paltry, futile affairs, filled him with melancholy, and he was glad to get away again leaving the place to the jungle, the birds and beasts that now laid claim to it.

"Sic transit gloria mundi!" he murmured, as with sad eyes he mused upon the down-tumbled columns along the facade, the overgrown entrance-way, the cracked and falling arches and architraves. "And _this_, they said, was builded for all time!"

It was on one of these expeditions that the engineer found and pocketed--unknown to Beatrice--another disconcerting relic.

This was a bone, broken and splintered, and of no very great age, gnawed with perfectly visible tooth-marks. He picked it up, by chance, near the west side of the ruins of the old City Hall.

Stern recognized the manner in which the bone had been cracked open with a stone to let the marrow be sucked out. The sight of this gruesome relic revived all his fears, tenfold more acutely than ever, and filled him with a sense of vague, impending evil, of peril deadly to them both.

This was the more keen, because the engineer knew at a glance that the bone was the upper end of a human femur--human, or, at the very least, belonging to some highly anthropoid animal. And of apes or gorillas he had, as yet, found no trace in the forests of Manhattan.

Long he mused over his find. But not a single word did he ever say to Beatrice concerning it or the flint spear-point. Only he kept his eyes and ears well open for other bits of corroborative evidence.

And he never ventured a foot from the building unless his rifle and revolver were with him, their magazines full of high-power sh.e.l.ls.

The girl always went armed, too, and soon grew to be such an expert shot that she could drop a squirrel from the tip of a fir, or wing a heron in full flight.

Once her quick eyes spied a deer in the tangles of the one-time Gramercy Park, now no longer neatly hedged with iron palings, but spread in wild confusion that joined the riot of growth beyond.

On the instant she fired, wounding the creature.

Stern's shot, echoing hers, missed. Already the deer was away, out of range through the forest. With some difficulty they pursued down a glen-like strip of woods that must have once been Irving Place.

Two hundred yards south of the park they sighted the animal again. And the girl with a single shot sent it crashing to earth.

"Bravo, Diana!" hurrahed Stern, running forward with enthusiasm. The "deer fever" was on him, as strong as in his old days in the Hudson Bay country. Hot was the pleasure of the kill when that meant food. As he ran he jerked his knife from the skin sheath the girl had made for him.

Thus they had fresh venison to their heart's content--venison broiled over white-hot coals in the fireplace, juicy and savory--sweet beyond all telling.

A good deal of the meat they smoked and salted down for future use.

Stern undertook to tan the hide with strips of hemlock bark laid in a water pit dug near the spring. He added also some oak-bark, nut-galls and a good quant.i.ty of young sumac shoots.

"I guess _that_ ought to hit the mark if anything will," remarked he, as he immersed the skin and weighed it down with rocks.

"It's like the old 'shotgun' prescriptions of our extinct doctors--a little of everything, bound to do the trick, one way or another."

The great variety of labors now imposed upon him began to try his ingenuity to the full. In spite of all his wealth of practical knowledge and his scientific skill, he was astounded at the huge demands of even the simplest human life.

The girl and he now faced these, without the social cooperation which they had formerly taken entirely for granted, and the change of conditions had begun to alter Stern's concepts of almost everything.

He was already beginning to realize how true the old saying was: "One man is no man!" and how the world had _been_ the world merely because of the interrelations, the interdependencies of human beings in vast numbers.

He was commencing to get a glimpse of the vanished social problems that had enmeshed civilization, in their true light, now that all he confronted and had to struggle with was the unintelligent and overbearing dominance of nature.

All this was of huge value to the engineer. And the strong individualism (essentially anarchistic) on which he had prided himself a thousand years ago, was now beginning to receive some mortal blows, even during these first days of the new, solitary, unsocialized life.

But neither he nor the girl had very much time for introspective thought. Each moment brought its immediate task, and every day seemed busier than the last had been.

At meals, however, or at evening, as they sat together by the light of their lamp in the now homelike offices, Stern and Beatrice found pleasure in a little random speculation. Often they discussed the catastrophe and their own escape.

Stern brought to mind some of Professor Raoul Pictet's experiments with animals, in which the Frenchman had suspended animation for long periods by sudden freezing. This method seemed to answer, in a way, the girl's earlier questions as to how they had escaped death in the many long winters since they had gone to sleep.

Again, they tried to imagine the scenes just following the catastrophe, the horror of that long-past day, and the slow, irrevocable decay of all the monuments of the human race.

Often they talked till past midnight, by the glow of their stone fireplace, and many were the aspects of the case that they developed.
