They moved very slowly, and it was a long time before they came close enough to the cliff to see what their chances of a landing might be. They floated at last within two or three hundred yards of the cliff. It was very dangerous looking; the waves rolled over huge black rocks at its foot and broke in white foam against its side; it seemed the last place in the world for a landing. A great swell rolled in from the sea and brought them nearer the breakers. "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. "Found 'em in the tin with the biscuits," said Toby. He held the candle on high so that its little beam searched out the darkness in front and on both sides. They were in a narrow passage-way. On each side was a wall of solid rock, not ten feet beyond the edge of the raft. How high the wall was they could not tell, for it was lost in the darkness overhead. They were slipping along a narrow alley-way of water. Toby held the candle higher, and everyone peered into the darkness ahead; but it was impossible to see more than a few yards. "I wish it distinctly understood," said the Sly Old Codger, "that I am here under--"
