Ah Kew let them in with a wise smile and several nods of his head, and soon both Dick and Grizzel were sleeping as soundly as the other four Time-travellers.

"It is a green diamond," Mr. Fraser pronounced next morning, "but what its value is we cannot tell until it is cut and polished. Then it will belong to Grizzel, to have and to hold till death do them part. If you really have found a diamond-mine, youngsters, something will have to be done about shares. Who finds keeps, you know. We'll have the place properly surveyed and see what happens. But don't begin counting your chickens too soon—these Australian diamond-mines are tricksy things; you never know how they are going to pan out. Wait a bit before you plan what to do with your fortune."

Mollie, Dick, and Jerry suddenly felt very sad as they remembered that they were out of this stroke of luck. Whatever happened, Fortune was not preparing to smile on them, at least not in a way that would be of any immediate practical use to them when they got back to London. And a fortune apiece would have come in so very handy just now—just forty years hence, that is. The boys made up their minds to investigate this matter of fortunes in the colonies directly they got home.

Hugh tossed up his hat and caught it again: "We'll be jolly rich," he cried. "The Mater will get her trip home, and the Pater needn't worry about bills and subscription lists any more, and I'll get that camera—oh, 'hard times, hard times, come again no more!'"

Mollie sat up. The clock was still ticking minutes into hours, hours into days, days into weeks and months and years.

"Oh dear," she said, "I do wonder—"

"Wonder what, my Molliekins?" asked Aunt Mary, preceding Hester with the tea-tray.

"I wonder," Mollie repeated, and then began to laugh. "I don't suppose you ever bit like red-hot nippers, did you, Aunt Mary?"
