"She said, 'Go home to your supper; you have seen quite enough; go home in good time.'"

"Doctor, there is something wrong!" said Alice. "I see it in your face. Can you trust me, and tell me what it is?"

"I can trust you so far as to tell you that you are right. I don't like the look of things at all. I fear there are evil times coming for some of our friends! Further than this I can say nothing. Say your prayers, and trust God! Don't tell Sam anything about this: to-morrow I shall speak to him. We won't spoil a pleasant holiday on mere suspicion."

They rejoined the others, and the Doctor said, "Come away home now; we have seen enough. Some future time we will come here again: you might see this fifty times, and never get tired of it."

After a good scramble they stood once more on the down above, and turned to take a last look at the broad blue sea before they descended inland; at the first glance seaward, Halbert exclaimed,—

"See there, Doctor! see there! A boat!"

"It's only a whale, I think," said George Barker.

There was a black speck far out at sea, but no whale; it was too steady for that. All day the air had been calm; if anything, the breeze was from the north, but now a strong wind was coming up from the south-east, freshening every moment, and bringing with it a pent bank of dark clouds; and, as they watched, the mysterious black speck was topped with white, and soon they saw that it was indeed a boat driving before the wind under a spritsail, which had just been set.

"That is very strange!" said George Barker. "Can it be a shipwrecked party?"

"More likely a mob of escaped convicts from Van Diemen's Land," said Jim. "If so, look out for squalls, you, George, and keep your guns loaded."
