Ward shook his head. "Everything here is old, abandoned. Look—what is that?"
The figure of a giant creature, carved either from stone or marble and encrusted with phosphorous, stood lowering in their path. It was that of a winged beast with a human head. Its features were negroid in character; and so malignant was the expression of the staring face, so lifelike the execution of the whole statue, that a chill of fear ran through their veins. It was in Ward's mind that this gigantic carving was akin to the ones he had seen in Egypt, and as old, if not older.
Beyond the statue the rail curved and the grade leveled; and, rounding the bend, they were amazed to come upon a sort of "yard" where the rail stopped. In that enclosure, on several sidings, were submarine cars similar to the wrecked one they had abandoned. But that was not the sight which brought them to a breathless halt. Beyond the sidings stood what appeared to be a small building of gleaming crystal.
After a moment of breathless wonder they cautiously approached the bizarre structure. No dampness or phosphorus impaired the clarity of its walls. The material composing them felt vibrantly warm to the touch. It was not glass, yet it was possible to look without difficulty into the interior of the building, which appeared to be one large room containing nothing but a central device not unlike the filaments of an electric bulb. In fact, the whole building, viewed from the outside, reminded the two adventurers of a giant light globe. The filaments radiated a steady and somehow exhilarating light. The door—they knew it was a door because an edging of dark metal outlined its frame—gave admittance to the room.
"Shall we?" questioned Miles; and Ward answered doubtfully, "I don't know. Perhaps...."
But at last they turned the golden knob, felt the door give to their pressure, and stepped through the entrance into the soft radiance of the interior. Unthinkingly, Ward released his hold on the knob and the door swung shut behind them. Instantly there was a flash of light, and they were oppressed by a feeling of nausea: and then, out of a momentary pit of blackness, they emerged to find that the room of crystal had oddly changed its proportions and opaqueness. "Quick!" cried Ward; "let us get out of this place." Both men found the door and staggered forth.
Then, at sight of what they saw, they stood rooted to the spot in sheer amazement. The gloomy tunnel and the sidings of submarine cars had vanished, and they were standing in a vast hall, an utterly strange and magnificent hall, staring up into the face of a creature crudely human and colored green!
The green man was almost of heroic proportions; he was clad in but a breech-clout, and was so broad as to appear squat in stature. He carried a short club, and appeared almost as dumbfounded as the two Americans. A moment he regarded them, then, with a ferocious snarl of rage, he hurled himself upon the startled Ward and half clubbed, half pushed him to the floor. Recovering from his momentary inaction and realizing the danger in which his friend stood, Miles shouted and leaped upon the green man's back, fastening his sinewy fingers about the giant's throat.
