Presently the shore began to curve round to the right. Aboutquarter of an hour later， after they had crossed a rocky ridge which ran out into a point， it made quite a sharp turn. Their backs were now to the part of the sea which had met them when they first came out of the wood， and now， looking ahead， they could see across the water another shore， thickly wooded like the one they were exploring.
“I wonder， is that an island or do we join on to it presently？” said Lucy.
“Don’t know，” said Peter and they all plodded on in silence.
The shore that they were walking on drew nearer and nearer to the opposite shore， and as they came round each promontory the children expected to find the place where the two joined. But in this they were disappointed. They came to some rocks which they had to climb and from the top they could see a fairway ahead and- “Oh， bother！” said Edmund， “it‘s no good. We shan’t be able to get to those other woods at all. We‘re on an island！”
It was true. At this point the channel between them and the opposite coast was only about thirty or forty yards wide； but theycould now see that this was its narrowest place. After that， their own coast bent round to the right again and they could see open sea between it and the mainland. It was obvious that they had already come much more than halfway round the island.
“Look！” said Lucy suddenly. “What’s that？” She pointed to a long， silvery， snake-like thing that lay across the beach.
“A stream！ A stream！” shouted the others， and， tired as they were，they lost no time in clattering down the rocks and racing to the fresh water. They knew that the stream would be better to drink farther up， away from the beach， so they went at once to the spot where it came out of the wood. The trees were as thick as ever， but the stream had made itself a deep course between high mossy banks so that by stooping you could follow it up in a sort of tunnel of leaves. They dropped on their knees by the first brown， dimply pool and drank and drank， and dipped their faces in the water， and then dipped their arms in up to the elbow.
“Now，” said Edmund， “what about those sandwiches？”
“Oh， hadn‘t we better have them？” said Susan. “We may need them far worse later on.”
“I do wish，” said Lucy， “now that we’re not thirsty， we could go on feeling as not-hungry as we did when we were thirsty.”
“But what about those sandwiches？” repeated Edmund.“ There‘s nogood saving them till they go bad. You’ve got to remember it‘s a good deal hotter here than in England and we’ve been carrying them about in pockets for hours.” So they got out the two packets and divided them into four portions， and nobody had quite enough， but it was a great deal better than nothing. Then they talked about their plans for the next meal. Lucy wanted to go back to the sea and catch shrimps， until someone pointed out that they had no nets. Edmund said they must gather gulls‘ eggs from the rocks， but when they came to think of it they couldn’t remember having seen any gulls‘ eggs and wouldn’t be able to cook them if they found any. Peter thought to himself that unless they had some stroke of luck they would soon be glad to eat eggs raw， but he didn‘t see any point in saying this out loud. Susansaid it was a pity they had eaten the sandwiches so soon. One or two tempers very nearly got lost at this stage. Finally Edmund said：
“Look here. There’s only one thing to be done. We must explore the wood. Hermits and knights-errant and people like that always manage to live somehow if they‘re in a forest. They find roots and berries and things.”
“What sort of roots？” asked Susan.
“I always thought it meant roots of trees，” said Lucy.
“Come on，” said Peter， “Ed is right. And we must try to do something. And it’ll be better than going out into the glare and the sun again.”
So they all got up and began to follow the stream. It was very hard work. They had to stoop under branches and climb over branches， and they blundered through great masses of stuff like rhododendrons and tore their clothes and got their feet wet in the stream； and still there was no noise at all except the noise of the stream and the noises they were making themselves. They were beginning to get very tired of it when they noticed a delicious smell， and then a flash of bright colour high above them at the top of the right bank.
“I say！” exclaimed Lucy. “I do believe that‘s an apple tree.”
It was. They panted up the steep bank， forced their way through some brambles， and found themselves standing round an old tree that was heavy with large yellowish-golden apples as firm and juicy as you could wish to see.
“And this is not the only tree，” said Edmund with his mouth full of apple. “Look there-and there.”
“Why， there are dozens of them，” said Susan， throwing away thecore of her first apple and picking her second. “This must have been an orchard-long， long ago， before the place went wild and the wood grew up.”
“Then this was once an inhabited island，” said Peter. “And what’s that？” said Lucy， pointing ahead.
“By Jove， it‘s a wall，” said Peter. “An old stone wall.”
