"Is there another?" she asked eagerly.

"Yes, and I wish we had the shade of Darwin, of Haeckel or of Clodd here with us to help us work it out!"

"How do you imagine it?"

"Why, like this. Maybe, after all, even the entire black race was swept out along with the others, too. Perhaps you and I were really the only two human beings left alive in the world."

"Yes, but in that case, how--?"

"How came _they_ here? Listen! May they not be the product of some entirely different process of development? May not some animal stock, under changed environment, have easily evolved them? May not some other semi-human or near-human race be now in process of arising, here on earth, eventually to conquer and subdue it all again?"

For a moment she made no answer. Her breath came a little quickly as she tried to grasp the full significance of this tremendous concept.

"In a million years, or so," the engineer continued, "may not the descendants of these things once more be men, or something very like them? In other words, aren't we possibly witnessing the recreation of the human type? Aren't _these_ the real pithecanthropi erecti, rather than the brown-skinned, reddish-haired creatures of the biological text-books? There's our problem!"

She made no answer, but a sudden overmastering curiosity leaped into her eyes.

"Let me see them for myself! I must! I will!"

And before he could detain her, the girl had started back into the room whence they had come.

"No, no! No, Beatrice!" he whispered, but she paid no heed to him.

Across the littered floor she made her way. And by the time Stern could reach her side, she had set her face to the long, crumbling crack in the wall and with a burning eagerness was peering out into the forest.

CHAPTER XXI

EVE BECOMES AN AMAZON

Stern laid a hand on her shoulder, striving to draw her away.

This spectacle, it seemed to him, was no fit sight for her to gaze on.

But she shrugged her shoulders as if to say: "I'm not a child! I'm your equal, now, and I must see!" So the engineer desisted. And he, too, set his eye to the twisting aperture.

At sight of the narrow segment of forest visible through it, and of the several members of the Horde, a strong revulsion came upon him.

Up welled a deep-seated love for the memory of the race of men and women as they once had been--the people of the other days. Stern almost seemed to behold them again, those tall, athletic, straight-limbed men; those lithe, deep-breasted women, fair-skinned and with luxuriant hair; all alike now plunged for a thousand years in the abyss of death and of eternal oblivion.

Never before had the engineer realized how dear, how infinitely close to him his own race had been. Never had he so admired its diverse types of force and beauty, as now, now when all were but a dream.

"Ugh!" thought he, disgusted beyond measure at the sight before him.

"And all _these_ things are just as much alike as so many ants in a hill! I question if they've got the reason and the socialized intelligence of ants!"

He heard the girl breathe quick, as she, too, watched what was going on outside. A certain change had taken place there. The mist had somewhat thinned away, blown by the freshening breeze through Madison Forest and by the higher-rising sun. Both watchers could new see further into the woods; and both perceived that the Horde was for the most part disposing itself to sleep.

Only a few vague, uncertain figures were now moving about, with a strangely unsteady gait, weak-kneed and simian.

In the nearest group, which Stern had already had a chance to study, all save one of the creatures had lain down. The man and woman could quite plainly hear the raucous and b.e.s.t.i.a.l snoring of some half-dozen of the gorged Things.

"Come away, you've seen enough, more than enough!" he whispered in the girl's ear.

She shook her head.

"No, no!" she answered, under her breath. "How horrible--and yet, how wonderful!"

Then a misfortune happened; trivial yet how direly pregnant!

For Stern, trying to readjust his position, laid his right hand on the wall above his head.

A little fragment of loose marble, long since ready to fall, dislodged itself and bounced with a sharp click against the steel I-beam over which they were both peeking.

The sound, perhaps, was no greater than you would make in snapping an ordinary lead-pencil in your fingers; yet on the instant three of the Things raised their bulbous and exaggerated heads in an att.i.tude of intense, suspicious listening. Plain to see that their senses, at least, excelled those of the human being, even as a dog's might.

The individual which, alone of them all, had been standing, wheeled suddenly round and made a step or two toward the building. Both watchers saw him with terrible distinctness, there among the sumacs and birches, with the beauty of which he made a shocking contrast.

Plain now was the simian aspect, plain the sidelong and uncertain gait, bent back and crooked legs, the long, pendulous arms and dully ferocious face.

And as the Thing listened, its hair bristling, it thrust its villainous, apelike head well forward. Open fell the mouth, revealing the dog-teeth and the blue, shriveled-looking gums.

A wrinkle creased the low, dull brow. Watching with horrified fascination, Stern and Beatrice beheld--and heard--the creature sniff the air, as though taking up some scent of danger or of the hunt.

Then up came the right arm; they saw the claw-hand with a spear, poise itself a moment. From the open mouth burst with astounding force and suddenness a snarling yowl, inarticulate, shrill, horrible beyond all thinking.

An instant agitation took place all through the forest. The watchers could see only a small, fan-like s.p.a.ce of it--and even this, only a few rods from the building--yet by the confused, vague noise that began, they knew the alarm had been given to the whole Horde.

Here, there, the cry was repeated. A shifting, moving sound began. In the visible group, the Things were getting to their handlike feet, standing unsteadily on their loose-skinned, scaly legs, gawping about them, whining and clicking with disgusting sounds.

Sudden, numbing fear seized Beatrice. Now for the first time she realized the imminent peril; now she regretted her insistence on seeing the Horde at close range.

She turned, pale and shaken; and her trembling hand sought the engineer's.

He still, for a moment, kept his eye to the crack, fascinated by the very horror of the sight. Then all at once another figure shambled into view.

"A female one!" he realized, shuddering. Too monstrously hideous, this sight, to be endured. With a gasp, the man turned back.

About Beatrice he drew his arm. Together, almost as soundlessly as wraiths, they stole away, out through the office, out to the hallway, into the dim light of the arcade once more.

Here, for a few moments, they knew that they were safe. Retreat through the Marble Court and up the stairs was fairly clear. There was but one entrance open into the arcade, the one through Pine Tree Gate; and this was blocked so narrowly by the giant bole that Stern knew there could be no general mob-rush through it--no attack which he could not for a while hold back, so long as his ammunition and the girl's should last.

Thus they breathed more freely now. Most of the tumult outside had been cut off from their hearing, by the retirement into the arcade.

They paused, to plan their course.

At Stern the girl looked eagerly.

"Oh, oh, Allan--how horrible!" she whispered. "It was all my fault for having been so headstrong, for having insisted on a look at them!

Forgive me!"

"S-h!" he cautioned again. "No matter about that. The main thing, now, is whether we attack or wait?"
