"That is so stupid of people," said Pickle; "they are always like that. If they'd know we went over to our city of refuge alone in a boat, I believe they'd have stopped us; but we never came to any harm, and now that we can sail like bricks, and manage a boat quite easily, they'd go on, saying just the same things as when we'd never been out or had any lessons. So it's no good talking; we'd better keep it our secret, like the island. But now that the windy time of year is coming, we can go out sailing often. We'll have jolly fun, if some stupid old fisherman doesn't see us and tell; but there seems nobody about to-day anyway."

"I expect it was too hot and bright for fishing," said Milly. "I know fishermen like dull days or the nights best."

A low rumble from the shore boomed through the air, and the children looked round.

"I think it's a thunderstorm over there," said Puck, "but it's jolly and fine out here."

"There! I saw a flash of lightning come out of the big black cloud!" cried Milly. "It was so pretty. I don't mind lightning when I'm right away from it out here. I don't much like it at home. Let's sail away from it, Pickle, right away. It's quite fine the way we're going, and we go so fast. We shan't have it at all. And when mother wonders why we're not wet or anything, we shall just say it didn't rain where we were. It's like the Israelites and the land of Goshen."

Pickle looked just a little doubtfully at the weather. The sun was almost obscured now, though it still shone over the sea away to the west and south. The wind was coming up in squally gusts behind them, and sending the boat dancing along merrily. It was certainly great fun sailing on like that, but the waves were beginning to grow rather bigger out here than they had looked from inside the bay, and when the wind came rushing along, there were sometimes little crests of foam to be seen, and now and then these dashed into the boat.

"I think, perhaps, we'd better put her about now," he said, with a look of wise command directed towards Puck; "the storm might come over here, you know, and then we should get very wet—at least if it rained. You know how to put her helm round, Puck, don't you? Or shall I come and do it?"

"Of course I know," answered Puck rather indignantly; "you just manage the sail. It always flaps a great deal when we put her round on the other tack."

Milly and Bertie, greatly impressed by this nautical language, sat as still as mice watching their companions. Milly was rather disappointed at hearing they were to go back, but now that the sun was obscured and the wind getting up, it wasn't quite so nice upon the water, and Bertie was looking very solemn indeed.

"You're not frightened, are you?" she whispered.
