"And was there somebody here, really?" asked Ted eagerly.
"Yes," answered his grandfather. "See. Here are bits of bread scattered about, and papers in which some one brought his lunch here."
"Maybe it was the tramps," whispered Janet.
"Maybe," agreed Mr. Martin. "I must have another look over the island."
There was not much else in the cave that they could see with the one lantern. Grandpa Martin wanted to look about more, and back in the far corners, but he did not like to take the children along, and Jan held tightly to his hand as if she feared she would lose him.
"I"ll come here alone some other time, and see what I can find," thought Grandpa Martin to himself, as they came out.
"I don"t like it in there," said Jan, once they were again out in the sunshine. "I don"t like caves."
"I do," declared Ted. "When Hal Chester comes to visit me, as he said he would, he and I will look all through this cave."
"Is Hal coming?" asked Jan, remembering the boy, once lame but now cured, who had played with them and told them about Princess Blue Eyes.
"Yes, mother asked him to come and spend a week, and he said he would.
We"ll have some fun in the cave."
"What do you suppose the big hole can be?" asked Mrs. Martin, when Grandpa Martin and the children reached camp after their visit to the strange place.
"I don"t know," he answered. "It doesn"t seem to have been dug with picks and shovels. It"s just a natural cave I guess, and some fishermen may have eaten their lunch there one day when it rained. But there is no one in it now."
Ted and Jan talked much about the cave the rest of that day. They went for a ride in the wagon drawn by Nicknack, taking Trouble with them. On their way back Jan said:
"Oh, I wish I had a swing."
"It would be fun," agreed Ted. "Maybe I can make one."
"You"ll have to get a rope," said his sister. "Grandpa is going to row over in the boat to-morrow. Ask him to bring us one."
"No, he don"t need to bring us a rope," went on her brother.
"Why not?"
""Cause I can get a rope in the woods."
"A rope in the woods? Oh, Teddy Martin, you can not! Ropes don"t grow on trees."
"The kind I mean does," answered Ted with a laugh. "Wait and I"ll show you."
When Nicknack had been put in the new stable which Grandpa Martin had built for him, Teddy, followed by Jan and Trouble, walked a little way into the woods. Ted carried with him a piece of old carpet.
"What"s that for?" his sister asked.
"For a swing board," he answered.
"But where"s the swing rope?"
"Here!" cried Ted suddenly. He pointed to a long wild grapevine, which hung dangling between two trees, around which it was twined. The vine was a very long one, and as thick around as the piece Teddy had used to pull himself out of the hole near the cave. It did seem like a regular swing.
"Well--maybe," murmured Jan.
"Now we can have some fun!" cried Ted. He folded the piece of carpet and laid it over the grapevine. Then he sat down, gave a push on the ground with his feet, and away he swung as nicely as though he was in a regular swing, made with a rope from the store.
"Oh, how nice!" cried Janet. "Let me try it, Teddy."
"Wait till I see if it"s strong enough."
He swung back and forward several more times and then let his sister try it. She, too, swayed to and fro in the grapevine swing, which was in a shady place in the woods. Then Trouble, who had seen what was going on, cried:
"I want to swing, too! I want to swing!"
"I"ll take you on my lap," offered Janet, and this she did.
"I"ll push you," offered Teddy, and he gave his sister and his baby brother a long push in the grapevine swing.
But, just as they were going nicely and Trouble was laughing in delight, there was a sudden cracking sound and Janet cried:
"Oh, I"m falling! I"m falling! The swing is coming down!"
And that is just what happened.
CHAPTER XI
TROUBLE MAKES A CAKE
With a crackle and a snap the grapevine swing sagged down on one side.
Janet tried to hold Trouble in her arms, but he slipped from her lap, just as she slipped off the piece of carpet which Ted had folded for the seat of the swing. Then Janet toppled down as the vine broke, and she and her little brother came together in a heap on the ground.
"Oh!" exclaimed Ted. "Are you hurt?"
Neither Jan nor Trouble answered him for a moment. Then Baby William began to cry. Jan lay still on the ground for a second or two, and then she jumped up with a laugh.
"I"m not hurt a bit!" she said. "I fell right in a pile of leaves, and it was like jouncing up and down in the hay."
"What"s the matter with Trouble?" asked Ted.
Baby William kept on crying.
"Never mind!" put in Jan. "Sister"ll kiss it and make it all better!
Where is you hurt, Trouble dear?"
The little fellow stopped crying and looked up at Jan, his eyes filled with tears.
