Never before had they been in the open air save when the sun was shining. All their time had been spent in the warm and airy ways and halls and rooms of the latter-day city. It was to them that night as if they were in some other world, some disordered chaos of stress and tumult, and almost beyond hoping that they should ever see the city ways again.

The storm seemed to last interminably, until at last they dozed between the thunderclaps, and then very swiftly it fell and ceased. And as the last patter of the rain died away they heard an unfamiliar sound.

"What is that?" cried Elizabeth.

It came again. It was the barking of dogs. It drove down the desert lane and passed; and through the window, whitening the wall before them and throwing upon it the shadow of the window-frame and of a tree in black silhouette, shone the light of the waxing moon....

Just as the pale dawn was drawing the things about them into sight, the fitful barking of dogs came near again, and stopped. They listened. After a pause they heard the quick pattering of feet seeking round the house, and short, half-smothered barks. Then again everything was still.

"Ssh!" whispered Elizabeth, and pointed to the door of their room.

Denton went half-way towards the door, and stood listening. He came back with a face of affected unconcern. "They must be the sheep-dogs of the Food Company," he said. "They will do us no harm."

He sat down again beside her. "What a night it has been!" he said, to hide how keenly he was listening.

"I don't like dogs," answered Elizabeth, after a long silence.

"Dogs never hurt any one," said Denton. "In the old days—in the nineteenth century—everybody had a dog."
