In the minds of the English children, now listening breathlessly, there arose a vividly distinct image of an aeroplane, darkly silhouetted against a pale English sky. How many they had seen!

Hugh's mutterings ceased. It seemed to Mollie that the world had grown very still. She fancied that she could almost hear the blossoms dropping on the grass; there was a faint stir of leaves as a stray breeze came wandering by, and another sound mingled with that stir—a far-away hum—hum—growing louder every moment!

The English children looked at each other. Was this one of Grizzel's miracles? Their eyes turned to the sky—yes, there it came! It winged its way like a mighty bird, singing its strange rough song. Prue dropped her work and stood up, Grizzel let fall her pencil and clung to Prue, Hugh leapt to his feet and ran down the steps, his face upturned to the clouds.

"Oh, what is it?" he cried. "What is it? Who are you?"

The aeroplane swooped down as the bird had done, till it was straight overhead, then, with a lovely curve, it skimmed away, the great wings outstretched as the bird's had been, away into the distant blue!

Hugh held out his arms. "Don't go—oh, don't go!" he cried. "Come back, come back!"

But it had gone.

The English children looked at each other again, and from each other to
Hugh.

"We brought it," whispered Jerry, "it was a Time-traveller."

Mollie turned to the Australians. The sunlight fell on Hugh's pale face, on Grizzel's ruddy curls; there was a faint smile on Prue's lips.
