Omega wondered whether electric safeguards would keep this creature from coming some night to the cottage and sticking his loathsome head in at door or window. Omega shuddered at the thought, but refrained from mentioning such a possibility to Thalma.

Having selected a site under the branches of a great coral tree standing within the shade of an overhanging rock, Omega erected a cottage. It took him but a few days to build and furnish this building from supplies on the ship. It was complete in every feature, even to running water from the lake. Grass was brought from the lake and a lawn laid out about the cottage in the shadows of the rock. The grass was kept watered for Thalma's sake, even though the water was needed for other purposes and the lake was diminishing steadily. But she was sacred in his eyes—she the last mother the old earth ever was to know.

The interior of the cottage was embellished like a palace, for treasures were brought from the airship to grace its walls. The richest rugs, curtains, tapestries and silks the world had ever known were there for Thalma's pleasure and comfort. Paintings of green verdure, of forests and plains of waving grass, of tumbling mountain streams and cool, placid lakes, Omega drew from the young days of the earth. The power to portray nature's moods and beauties had increased in many men with the passing of time. He placed these scenes before Thalma's couch that their cool and inspiring presence might comfort her while she awaited the coming of the child.

One morning being weary of the stark monotony of the valley, whose eastern wall was distant many miles, Omega and Thalma determined to scale the heights above. For sometimes in the sinister aspect of the chasm's walls, it seemed that the rocks would close together and crush out their lives. They concluded not to take the air-car, but to go on a rambling picnic with the ever present hope that they might discover another oasis of life.

Hand in hand they rose into the air, up and up for miles past frowning cliffs and dark caverns, yawning like grinning skulls above the outposts of death. There was no visible effort in their flight. They but took advantage of nature's laws which man had long understood. At last on the highest peak they paused to rest on a dust-covered rock.

The red sun rose above the cheerless horizon and blazed on them from a deep azure sky slashed across by bars of purple and gold. More than nine miles beneath them spread the deep gorge, where nestled their little home, looking like a doll-house, and above it shone the great, silver ship. The lake shone like a speck of silver on the drab rocks. They gazed down upon it in an attitude of worship, for it alone in all that vast realm of peaks and plains and valleys symbolized life. Then suddenly a dark speck appeared on the surface of the lake. Omega looked at Thalma apprehensively, for well he knew the meaning of that speck. Her face was pale and drawn, and she clung to Omega as they pointed their glasses at the water.

The monster was again disporting himself. He threshed the water into foam with his long, sinuous body, while his head wagged and his terrible eyes looked toward the land. It was the first sight they had had of him since the night he almost killed Omega.

"Look!" breathed Thalma, "it is coming ashore. Oh, I did hope that it was dead!" And trembling violently she clung closer to her lord.

"Never mind, dear," consoled Omega as he watched the great beast waddle toward the shore. "We will get him this time," he went on exultingly. "Watch—he is going to get into the trap!"

But they were again doomed to disappointment. Within a few rods of the shore, with its great, spotted body nearly all out of the water, the monster stopped, lifted its head and looked slowly around in every direction. Then apparently scenting danger, it turned, floundered back to the center of the lake and submerged.

"I—I—am afraid," shuddered Thalma.

"There is nothing to fear," reassured Omega. "The beast cannot get to our home, and one of these days he will either get caught in a trap or we will get a shot at him."

Although Omega spoke bravely he was really worried about the beast and the influence it was having on Thalma. He realized that he must at once devise a better method of extermination. Even though he did not fear it so much personally its presence was disturbing, and it was daily absorbing so much water needful for themselves.

This great gash in the earth's crust stretching for many miles below them had been the deepest part of the Pacific Ocean when its blue waves still lapped the shores of continents, and that little lake, far down in the earth's bosom, was the pitiful remainder of that once mighty sea. Far to the north-west, showing plainly against the sky in the focus of their binoculars, were great ridges of mountain and table land, rising gaunt and desolate from the ancient bed of the sea—the site of the ancient empire of Japan. Round about them on every hand were the mute remains of marine life, for the spot where they sat had been far below the surface of the sea. Silent, mysterious, hopeless and dreary, the prospect appalled even their stout hearts. How they yearned for the sight of some living thing there upon those high peaks. Silence supreme and dreadful, in which even their voices, hushed and tremulous, sounded profane, cowed them by its unending solemnity and the relentless grip. Gray and nude save for their pall of dust the mountains rose into the sky, eternal in their ghostly majesty. And the dark valleys between with their gray lips of death looked like the gaping mouths of hell.

"Death! death! eternal and triumphant death, thou art everywhere!" cried Omega, springing up and gazing with hopeless eyes about over the desolation.

Thalma rose and touched his arm. A smile of faith and confidence shone on her face. He looked at her in wonder.

"Nay, death is not everywhere," she reproved gently. "Remember Alpha, our son. In him life does and will live again."

"Forgive me, Thalma," said Omega, taking her in his arms. "You speak truly. With your loyalty and courage I know we will win."

And so as it had always been from the beginning of time, even so in these last days it took woman's love and devotion to sustain man.

Now Omega gazed around on the abode of death with an expression of disdain. He challenged it and dared it to do its worst. Life still triumphed, for he had Thalma and Alpha was coming soon. He would not surrender. He would fight the dark forces of death—even that horrible monster down there in the lake—and conquer them all. He would again 'gardenize' the world. The stubborn power of hope, that heritage from his atavistic ancestors, was surging through his blood.

"We will change all this," he went on, waving his hand toward the far rim of the sky. "We are still masters of life. But now let us descend," he added in answer to her approving smile.

So saying again hand in hand they stepped off into space and floated easily down toward their last home.

Omega knew that his first important task was to get rid of the beast. The fear-haunted expression in Thalma's eyes brooked no delay. Accordingly they went to the ship, and each taking a small sack they filled them with depth bombs. Thus armed they floated out over the lake in quest of their enemy. But although quite shallow the water was opaque for the most part being discolored by vegetable matter stirred up by the monster, and the transparent portions were too deep for them to see bottom. Long and carefully they searched at a safe distance above the water, but no sight of the beast could be seen. Then hoping that a chance shot might reach and destroy him they passed to and fro over the lake's center and dropped their bombs. Great columns of water were sent high in air deluging them with spray. That was all. Still, they had no way of knowing whether a bomb had struck home. In
