Mavis entered with a tray laden with tea and biscuits—the exertion had done her good, and already there was a slight colour in her cheeks.
The airship was ploughing along at a terrific rate, but its motion was steady, and they could walk about in comfort. When first the explosion that had accompanied the end of the world sent them spinning into the infinite unknown, the Argenta had behaved in a most erratic way. Broadside she skimmed like an arrow, throwing them from side to side, then she reared up on her tail, and climbed the heavens almost perpendicularly; then she would roll over and over, porpoise-like, until the frail mortals lost all sense of everything except that a great calamity had come into their lives.
“Where are we?” asked Mavis suddenly.
“I intend to try and find out,” said Masters grimly. “Whatever happens we can’t be in a worse position than we are at this moment. I intend to move the shutters from the bows and then we may get some idea of where we are.”
“But is it safe?” objected Desmond, looking first at his wife and then at his child. “So far we are safe. This mad journey must come to an end some time or other. Why jeopardize all our lives for the sake of a little curiosity?”
“Must it come to an end?” said Sir John thoughtfully.
“Of course,” answered Desmond. “We can’t go on forever.”
“Why not?” continued his Uncle. “Space is infinite. Now time is eternity. We, when in the world—”
“How strange that sounds,” interrupted Alan.
“As I was saying, when we were in the world, we often used the expression, ‘For ever and ever.’ If we thought what it really meant, it dazed our brains; we wanted to probe further, and find out what it was that came after that ‘ever and ever.’ We puzzled our intellects by pondering on the infinity of time. I realize now, what Eternity is! Since we have been here, I have ceased to count the minutes; I have ceased to think of days, or night, or weeks. Time is! That is enough for me.”
