"My word!" cried Mr. Punch, excitedly. "There's a harch!"

"A what?" said Toby.

"See!" said Aunt Amanda. "There's a little archway in the rock, like the mouth of a cave, over there to the right! Don't you see? With the water pouring in! Over there!"

It was true. There was an archway, like the mouth of a cave; and into this the water was streaming in a strong current, making a kind of passage-way, more or less smooth, through the breakers.

"Yes!" said Freddie. "And I believe we're headed towards it!"

Their course changed a little to the right, as if the fish who was piloting them had now taken a correct bearing. They found themselves in a passage through the breakers where the water swirled in towards the arch. They were caught in this current and were swept to a point close under the towering black rocks, and in another moment they were directly before the opening. The current seized the raft as if with strong hands and drew it in.

They were in a cavern, narrow and high, whose interior was lost in darkness. The current carried them onward into the dark. The roar of the breakers suddenly ceased, and as they looked behind them the archway was no more than a speck of light. Their raft turned slightly to the left, and at that moment the speck of light disappeared, as if they had turned

a corner; and the darkness became so black that no one could see even the person sitting next to him.

"I wonder," said Toby, "if there are any matches and candles on board this boat. I'm going to see."

He was silent for a while, and it was evident from the tilting of the raft that he had moved his position. Finally he said "Ah!" and a match spluttered and went out in the breeze which was blowing past them; but after it went out there remained a glimmer, and Toby was holding up a lighted candle, and shielding it from the draught with his hand.
