Every light, including those about the Mirror, had been extinguished by the beast breaking the circuit. Yet it appeared that the latter's passage through the electric wall had caused no harm. Omega explained that likely its bony scales had acted as an insulator against the action of the invisible wall.

While the cottage was being repaired they remained on the ship. But despite their recent harrowing experience, they went back to the cottage when the repairs were complete. It was more home-like than the ship, and Thalma had learned to love it, for it was to be the cradle of a new race. But before they again took up their residence there Omega had erected a high fence around the cottage yard. This fence was built of heavy cables securely fastened to huge posts, and each cable carried an electric charge of 75,000 volts. Omega was confident that the beast could never break through. His confidence was shared by Thalma, but as an additional precaution she suggested that Omega place a similar fence about the lake. He did so, and when the last cable was in place they stood back and surveyed the work with satisfaction.

"We have him now," exulted Omega. "He can never leave the lake alive, much less reach the cottage. Despite his tough armor of scales this high potential will penetrate to his vitals."

"It is well," said Thalma as they turned away.

As they neared the cottage they knew that a crisis was at hand. Forgetting the dead world about them and subduing the fears that sometimes clutched their hearts, they lived in the joy of anticipation and made ready for the advent of a new soul.

Night came down moonless and dark save for the light of the stars. In the recesses of the rocks and in the bottoms of the valleys intense darkness held sway. But the grounds and the home of Omega and Thalma were ablaze with a thousand lamps, and on the near-by hillsides giant searchlights, which seemed to have no basis, which were born in the bosom of the air and blazed without visible cause, shot their rays into the sky for miles. Yet the powerful lights about the cottage were so tinted as to be restful to the eye. Thus silent and with clock-like regularity the agents of Omega performed their functions. Man had mastered all the elements of life. All were his friends and servants, and none was his master save one—death.

In a perfect setting and exactly at the time set for the event Alpha came into the world, the child thrived from its first intake of earth's air.

Three weeks from birth Alpha partook of solid food in tablet form drawn chiefly from gaseous sources. At two months his speech was perfect, and at six months his education began. By glandular control Omega nurtured both his body and his mind and developed them rapidly. Small wonder that this child—the last to grace and bless the world—became his parent's only joy and hope. They guarded him from all dangers, instructed him in the great part he was to play in the world's future and set about to conserve that element on which all depended—the waters of the lake.


But during all these long, hot days and frigid nights, the close proximity of the monster cast a shadow over their souls, marred their happiness by day and terrorized their dreams by night. Often, when the sun beat down upon the lake, they saw his hideous head rise high above the water and regard them with baleful eyes. Twice while at play Alpha had seen him and had run screaming to the protection of his mother, who had great difficulty in persuading him that there was no danger. This seemed to be true, for the monster made no attempt to force the fence. Endowed with more than the cunning of its remote progenitors, it seemed to realize that it was trapped. Many nights Omega and Thalma, armed with their ray guns and other implements of destruction, watched for the beast to attempt to come on land. Sometimes he would raise his head and look at them so long and steadily that icy chills ran along their spines and their hands shook so that they could not sight their weapons and therefore shot wild. Then the head would sink out of sight again.
