at Aunt Jo's," said Laddie.

"I'm sure you will. I guess you could have fun anywhere, you six," said Mr. Hixon with a laugh. "Well, good-bye, if I don't see you again!"

"Good-bye!" said the others.

"Good-bye," echoed the parrot.

Grandma Bell, Mother Bunker and the four children went back to the shady cove of the lake.

"Where'd you go?" asked Russ and Rose, who were walking along to meet them.

"Oh, we thought somebody was lost in the woods," answered Laddie.

"But it was Mr. Hixon's parrot," added Vi.

The children went back to their play.

A day or so later they helped pack the things they had brought with them to Grandma Bell's.

"We're going to Aunt Jo's! We're going to Aunt Jo's!" shouted Rose, dancing about.

"In Boston! In Boston!" added Russ. "And we'll have Boston baked beans!"

The next day the children said good-bye to Grandma Bell and, with Daddy and Mother Bunker, started for Aunt Jo's. They hardly even dreamed of all the good times they were to have there, nor of the strange things that were to happen.

CHAPTER III

ON THE BOAT

From Grandma Bell's home, near Lake Sagatook, the six little Bunkers, with their father and mother, were taken to the railroad station in a big automobile. As the children looked back, waving their hands to their dear grandmother, who had made their visit such a pleasant one, Russ said:

"Oh, dear!"

"What's the matter?" asked his father. "You seem sad."

"I wish we could take that nice lake with us," explained Russ. "We had such fun there."

"And the boat, too," added Rose. "Can we have a boat at Aunt Jo's, Daddy?"

"I hardly think so," answered Mr. Bunker with a smile. "Aunt Jo lives in the city—in Boston, in the Back Bay section, and I hardly think there is a place there where you can paddle a raft."

"Can we go wadin'?" asked Laddie.

"Not unless there is a little lake in some park near by," his father answered.

"Couldn't we wait for it to rain and make a mud puddle?" asked Vi. "We could wade in that! We do when we're home!"

"But Boston isn't home. And you can't do in a big city the things you can do at home in Pineville," said Mrs. Bunker, as the automobile chugged along through the woods.

"Can't we have any fun?" asked Russ.

"Oh, yes, lots of fun," his father replied. "Aunt Jo wouldn't ask us to spend two weeks or more at her house, if she didn't know you children could have fun, even if she does live in a city. Don't worry about that—you'll have fun."

"But we can't have a boat," sighed Rose. She and the other children loved the water, and, living so near Rainbow River as they did, they were used to paddling about, playing with make-believe boats and toys like that.

"Well, if you can't have a boat at Aunt Jo's in Boston, you are going to ride on one before you get to her house," said Mother Bunker with a smile.

"Are we?" cried Russ and Rose together.

"Yes. Didn't I tell you about that?" asked Daddy Bunker. "We are going to Boston by boat, instead of by train. That is, we are going most of the way by boat."

"Where is there any water for a boat?" asked Vi, looking around in the woods through which they were riding. "You can't make a boat go lessen you have water."

"Oh, I know. Yes, you can! Yes, you can!" suddenly cried Laddie.

"How can you?" asked Russ. "You can't sail a boat without water."

"Yes, you can!" said Laddie again, and he was laughing now. "I just thought of a riddle. This is it. What kind of a boat can you sail without water? It's a riddle!"

"Huh! I should say it was! Nobody could answer a riddle like that!" declared Russ.

"Yes, they can!" insisted Laddie. "It's a riddle! And I made it up all by myself. Nobody told me, and I know the answer."

"Well, that's more than I do," said Mrs. Bunker with a laugh. "Suppose you tell us, Laddie."

"And then Daddy can tell us about the boat we're going to ride on to Aunt Jo's," suggested Rose.

"Yes, I'll do that," said Mr. Bunker. "Go on, Laddie. What is the riddle you thought of?"

"What kind of a boat don't have to go in water?" asked the little boy, his eyes shining, for he loved to make up riddles.

"Well, go on. Tell us the answer," said his mother.

"It's a gravy boat!" laughed Laddie. "You know, a gravy boat. It's the kind of a dish we have on the table, with gravy in it, for your bread. You don't have to put that kind of a boat in water."

"That's right! You don't," said Mr. Bunker. "That was a good riddle, Laddie."

"And maybe I could think up another one," went on the little boy. "I almost got one. It's about what makes bread always fall with the butter-side down. But I haven't thought of the answer yet."

"Well, don't tell us any more riddles now," said Russ. "We want to hear about the boat we're going to ride on to Aunt Jo's. Tell us, Daddy."

"All right, I will," promised the children's father.

Then he went on to tell that, by taking a train to a station on the coast, they could get a boat that would take them to Boston.

"We shall have to travel all night though, just as we did in the sleeping-car," said Mr. Bunker.

"Why?" asked Vi.

"Because it will take that long to reach Boston," explained her father.

Rose had quite a large doll, her best one, which she carried with her in her arms whenever the family went traveling. Rose had brought her doll to Grandma Bell's and something funny had happened to the doll in the sleeping-car. You may read about it in the book before this one.

"I must see if my doll is asleep," said Rose.

She had put her toy in a cosy corner of the auto seat, and covered her with a blanket. But when Rose went to look for Sue, as she called her doll, Sue was not to be found.

"Oh! Sue's gone! Sue's gone!" cried Rose. "Somebody has taken my Sue!"

"Who did?" asked Vi.

"Are you sure she hasn't fallen to the floor of the car?" asked Mrs. Bunker.

"No, she isn't here at all," wailed Rose.

"Maybe you didn't bring her. Perhaps you left her at Grandma Bell's," said Mr. Bunker.

"Oh, no! I'm sure I had her," sobbed Rose. "Don't you all 'member that I held her up and wiggled her hand at grandma to say good-bye?"

"Yes, I do remember that," said Mrs. Bunker. "Rose surely had her doll when we started. Have any of you children seen Sue?" she asked.

None of them had, and then Daddy Bunker called to the man driving the auto to stop.

"What are you going to do?" asked Mrs. Bunker.

"I thought I'd walk back a little way and see if Sue had not dropped out along the road," answered her husband.

"Have we got time for that? Won't the train go?"

"Well, we've got a little time," said the driver. "I'll get out and help you look, Mr. Bunker."

"Why'd you lose Sue, Rose?" asked Vi.

"Why, Vi Bunker, I didn't mean to lose her!" exclaimed Rose.

Rose was still searching among the blankets, hoping that, somehow or other, the doll might be found, and her father and Mr. Mead, the auto driver, were getting out, when they heard a shout behind them.

"That's some one calling," said Mrs. Bunker.

They looked and saw riding toward them a boy on a bicycle. He had something in one hand, and clung to the steering bars with the other.

"Oh, he has my doll! He has my doll! I can see Sue!" cried Rose, clapping her hands in joy. "He found her!"

"I do believe
