Over the ridge, following his guide's example, he turned about and slid backward down the opposite slope very swiftly, amid a little avalanche of snow While he was sliding he thought of what would happen if some broken gap should come in his way. At the edge he stumbled to his feet ankle deep in slush thanking heaven for an opaque footing again. His guide was already clambering up a metal screen to a level expanse.
Through the spare snowflakes above this loomed another line of vast windmills, and then suddenly the amorphous tumult of the rotating wheels was pierced with a deafening sound. It was a mechanical shrilling of extraordinary intensity that seemed to come simultaneously from every point of the compass.
"They have missed us already!" cried Graham's guide in an accent of terror, and suddenly, with a blinding flash, the night became day.
Above the driving snow, from the summits of the wind-wheels, appeared vast masts carrying globes of livid light. They receded in illimitable vistas in every direction. As far as his eye could penetrate the snowfall they glared.
"Get on this," cried Graham's conductor, and thrust him forward to a long grating of snowless metal that ran like a band between two slightly sloping expanses of snow. It felt warm to Graham's benurrled feet, and a faint eddy of steam rose from it.
"Come on!" shouted his guide ten yards off, and, without waiting, ran swiftly through the incandescent glare towards the iron supports of the next range of wind-wheels. Graham, recovering from his astonishment, followed as fast, convinced of his imminent capture.
In a score of seconds they were within a tracery of glare and black shadows shot with moving bars beneath the monstrous wheels. Graham's conductor ran on for some time, and suddenly darted sideways and vanished into a black shadow in the corner of the foot of a huge support. In another moment Graham was beside him.
They cowered panting and stared out.
The scene upon which Graham looked was very wild and strange. The snow had now almost ceased;only a belated flake passed now and again across the picture. But the broad stretch of level before them was a ghastly white, broken only by gigantic masses and moving shapes and lengthy strips of impenetrable darkness, vast ungainly Titans of shadow. All about them, huge metallic structures, iron girders, inhumanly vast as it seemed to him, interlaced, and the edges of wind-wheels, scarcely moving in the lull, Ipassed in great shining curves steeper and steeper up into a luminous haze. Wherever the snow-spangled light struck down, beams and girders, and incessant bands running with a halting, indomitable resolution passed upward and downward into the black. And with all that mighty activity, with an omnipresent sense of motive and design, this snow-clad desolation of mechanism seemed void of all human presence save themselves, seemed as trackless and deserted and unfrequented by men as some inaccessible Alpine snowfield.
"They will be chasing us," cried the leader. "We are scarcely halfway there yet. Cold as it is we must hide here for a space--at least until it snows more thickly again."His teeth chattered in his head.
"Where are the markets? " asked Graham staring out. "Where are all the people? "The other made no answer.
"Look!" whispered Graham, crouched close, and became very still.
The snow had suddenly become thick again, and sliding with the whirling eddies out of the black pit of the sky came something, vague and large and very swift. It came down in a steep curve and swept round, wide wings extended and a trail of white condensing steam behind it, rose with an easy swiftness and went gliding up the air, swept horizontally forward in a wide curve, and vanished again in the steaming specks of snow. And, through the ribs of its body, Graham saw two little men, very minute and active, searching the snowy areas about him, as it seemed to him, with field glasses. For a second they were clear, then hazy through a thick whirl of snow, then small and distant, and in a minute they were gone.
"Now!" cried his companion. "Come!"
He pulled Graham's sleeve, and incontinently the two were running headlong down the arcade of ironwork beneath the wind-wheels. Graham, running blindly, collided with his leader, who had turned back on him suddenly. He found himself within a dozen yards of a black chasm. It extended as far as he could see right and left. It seemed to cut off their progress in either direction.
"Do as I do," whispered his guide. He lay down and crawled to the edge, thrust his head over and twisted until one leg hung. He seemed to feel for something with his foot, found it, and went sliding over the edge into the gulf. His head reappeared.
"It is a ledge," he whispered. "In the dark all the way along. Do as I did."Graham hesitated, went down upon all fours, crawled to the edge, and peered into a velvety blackness.
For a sickly moment he had courage neither to go on nor retreat, then he sat and hung his leg down, felt his guide's hands pulling at him, had a horrible sensation of sliding over the edge into the unfathomable, splashed, and felt himself in a slushy gutter, impenetrably dark.
"This way," whispered the voice, and he began crawling along the gutter through the trickling thaw, pressing himself against the wall. They continued along it for some minutes. He seemed to pass through a hundred stages of misery, to pass minute after minute through a hundred degrees of cold, damp, and exhaustion.
In a little while he ceased to feel his hands and feet.
The gutter sloped downwards. He observed that they were now many feet below the edge of the buildings.
Rows of spectral white shapes like the ghosts of blind-drawn windows rose above them. They came to the end of a cable fastened above one of these white windows, dimly visible and dropping into impenetrable shadows. Suddenly his hand came against his guide's.
"Still!" whispered the latter very softly.
