"All right," agreed Ted, though he thought perhaps Baby William might be in the way at the gold mine.

"Where is he?" asked Jan.

They looked around for the little fellow. He was not in sight.

"He got down from the table and was playing over there on the path a while ago," said Grandpa Martin, and he pointed toward the path that led to the gold mine. But Trouble was not in sight now.

"He must have wandered off into the woods," said his mother. "I've kept him close by me all day, and he didn't like it. Trouble! William!" she called aloud. "Where are you?"

Ted and Jan looked at one another. Hal seemed startled. The same thought came to all three of them:

"Suppose Trouble had fallen down the big hole at the gold mine?"

CHAPTER XVI

A GLAD SURPRISE

Janet, Ted and Hal started to run.

"Where are you going?" called Mrs. Martin after them. "Wait for Trouble!"

"We're going to find him," answered Janet.

"Maybe he fell down the big hole we dug for a gold mine," added Ted.

"What do you mean?" gasped Mrs. Martin.

"What have you Curlytops been up to now?" asked Grandpa Martin.

"We dug a big hole to find the gold the tramps are looking for on this island," explained Hal, who walked on slowly, following Mrs. Martin, who had run after Ted and Janet. "Maybe the little boy fell into it."

"Where did you dig the big hole?" asked grandpa, and he, too, began to be afraid that something had happened.

"Up near what Ted calls the cave. It's got a ladder in it, our gold mine hole has, and maybe Trouble could climb out on that."

"If it's a hole deep enough for a ladder, I'm afraid he couldn't," said Grandpa Martin. "You children must have dug a pretty big hole."

"We wanted to find the gold," explained Hal.

"What gold?"

"The gold the tramps are looking for here on Star Island. Ted told me about them, and I suppose they were after gold. We want to find it first."

"There isn't any gold here, and you mustn't dig holes so deep that Trouble--or anyone else--would wander off and fall into them," said Mr.

Martin. "However, I presume it will be all right. But we must hurry there and find out what has happened."

He and Hal hastened on, following Mrs. Martin and the Curlytops, who were now out of sight around a turn in the path that led to the big hole. Hal was rather frightened, for he knew it was his idea, more than the plans of Jan and Ted, that had caused the "gold mine" to be dug.

On and on, along the path and up the hill hurried grandpa and Mrs.

Martin and the children. They called aloud for Trouble, but he did not answer. At least they could not hear him if he did. He must have gone quietly away from the table when no one noticed him. He had had his supper before the Curlytops and Hal came from their digging.

"There's the pile of dirt," called back Ted, who was running on ahead.

He pointed to the mound of yellow sand that he, Hal and Jan had dug out of the hole.

"And some one is there, digging!" cried Jan. "Oh, maybe it's Trouble!"

"I only hope he hasn't fallen in and hurt himself!" murmured Mrs.

Martin.

By this time Grandpa Martin and Hal had caught up to the others. They could all see some one making the dirt fly on top of the yellow mound of sand at one side of the big hole.

As Ted came nearer he saw a man on top of the dirt, using a shovel. The man was digging quickly, and at first Teddy thought it was one of the tramps. But a second look showed him he was wrong. And then came a glad surprise, for the man called:

"I'll have him out in a minute. He isn't under very deep!"

"Why it's the lollypop man!" cried Jan.

And so it was, Mr. Sander, the jolly, fat man who sold waffles and lollypops.

"Is Trouble in the hole? Are you digging him out?" gasped Mrs. Martin, and she felt as though she were going to faint, she said afterward.

"No! Trouble isn't here--I mean he isn't in the hole!" cried Mr. Sander.

"It's your goat, Nicknack, who's buried under the sand. But his nose is sticking out so he won't smother, and I'll soon have him all the way out."

"But where is Trouble?" cried Baby William's mother.

"There he is, safe and sound, tied to a tree so he can't get in the way of the dirt I'm shoveling out. I didn't want to throw sand in his eyes!"

cried the lollypop man. "Trouble is all right!"

And so the little fellow was, though he had been crying, perhaps from fright, and his face was tear-streaked and dirty. But he was safe.

With a glad cry his mother loosed the rope by which Mr. Sander had carefully tied Trouble to a near-by tree and gathered him up in her arms.

Meanwhile Grandpa Martin caught up one of the shovels and began to help the lollypop man dig in the sand. The Curlytops and Hal saw what had happened. A lot of the dirt they had shoveled out had slid back into the big hole, almost filling it. And caught under this dirt was Nicknack, their goat. Only the black tip of his nose stuck out, and it is a good thing this much of him was uncovered, or he might have smothered under the sand.

"How did it happen?" asked Ted.

"There must have been a cave-in at our gold mine," said Hal.

"But how did Nicknack get here?" Ted went on.

"I guess Trouble must have untied him and brought him here," suggested Janet.

Then they all watched while Grandpa Martin and the lollypop man dug out the goat.
