sometimes I work for Mr. Schmidt, a butcher. But I don't earn much. When I get through school I'll work all the while, and earn lots of money. Then I'm going to hire a ship and go to look for my father."

"I thought you said he was drowned in the ocean!" exclaimed Flossie.

"Well, maybe he is. But sometimes shipwrecked people get picked up by other vessels and carried a long way off. And sometimes they get on an island and have to stay a long time before they are taken off. Maybe that happened to my father."

"Oh, maybe it did!" cried Freddie. "That would be great! Just like Robinson Crusoe, Flossie! Don't you remember?"

"Yes, mother read us that story. I hope your father is on Robinson Crusoe's island," she whispered to Tommy.

"I'll tell you what we'll do," said Freddie to the new boy. "When I get home, I'll take all the money in my bank, and help you buy a ship. Then we'll both go off together, looking for the desert island where your father is; will you?"

"Yes," said Tommy, "I will, and thank you."

"I'm coming, too," said Flossie.

"No. Girls can't be on a ship!" said Freddie.

"Yes they can too! Can't they, Tommy?"

"Well, my mother was once on the ship with my father, I've heard my grandma say."

"There, see!" cried Flossie. "Of course I'm coming! I'll do the cooking for you boys."

"Oh, well, if you want to cook of course that's different," said Freddie, slowly, as he thought about it.

"I'm going to ask my father how much I got saved up," he went on to Tommy. "And how much it costs to buy a ship. He'll know for he sells lumber. You wait here and I'll ask him."

Freddie slipped from the seat into the aisle of the car. Flossie stayed to talk to Tommy. Bert and Nan were looking at a magazine which Mrs. Bobbsey had bought for them, and she and her husband were still talking to the fresh air lady. Scattered about the car, the fresh air children were talking and laughing, telling each other of the good times they had had in the country. All of them were sorry to go back to the city again.

"Papa," began Freddie, as he reached the seat where Mr. and Mrs. Bobbsey sat, "how much money have I saved up? And how much does a ship cost? 'Cause Tommy Todd and I are going off to look for his father who is lost on a desert island, and we want to bring him home. Does it take much money?"

Mr. Bobbsey looked at his little boy, wondering what he meant, and he was just going to answer him, and say it took much more money than Freddie had saved to buy a ship, when, all at once, the train came to such a sudden stop that Freddie was nearly thrown off his feet. His father caught him just in time.

"Oh!" cried Mrs. Bobbsey. "I hope there has been no accident!"

"If dey is I'se gwine t' git out quick!" cried Dinah. "Come on, chilluns. I'se got de cat!" and she started to run for the door, carrying the basket holding Snoop.

"Be quiet," said Mr. Bobbsey. "Nothing much seems to have happened. We didn't hit anything, anyhow."

Some of the fresh air children were excited, and the two ladies in charge hurried here and there quieting them.

Bert Bobbsey, who was with his sister Nan, looked out a window.

"Oh, see!" he cried. "A lot of men with guns are standing along the track. They stopped the train, I guess. They must be robbers! I'm going to hide my money!"

Several women heard Bert speak of robbers, and they screamed.

"Bert, don't be foolish!" said Mr. Bobbsey. "I dare say it isn't anything. I'll go out and see what it means."

"I'll come with you," said a man in the seat behind Mr. Bobbsey. Several other passengers also left the train. And while they are out seeking the cause of the sudden stop I'll tell my new readers something about the Bobbsey twins, so that they may feel better acquainted with them.

Those of you who have read the other books in this series, beginning with the first, "The Bobbsey Twins," know enough about the children already. But others do not.

There were two sets of Bobbsey twins. Bert and Nan were about ten years old. Both were tall and slim, with dark hair and eyes. Flossie and Freddie, who were about five years of age, were short and fat, and had light hair and blue eyes.

The Bobbseys lived in an Eastern city called Lakeport, near Lake Metoka, on the shore of which Mr. Bobbsey had a large lumber yard. Once this had caught fire, and Freddie had thought he could put the blaze out with his little toy fire engine. Ever since then Mr. Bobbsey had called the little chap "fireman."

Dinah Johnson was the Bobbsey's cook. She had been with them many years. And Sam, her husband, worked around the house, carrying out ashes, cutting the grass, and such things as that.

Besides these, the Bobbsey family consisted of Snap, the big dog who once had been in a circus and could do tricks, and Snoop, the black cat.

These pets were taken along wherever the Bobbsey twins went on their Summer vacations. For the Bobbseys used to spend each Summer either in the mountains or at the seashore. The second book tells about the good time they had in the country while the third one tells of their adventures at the shore.

"The Bobbsey Twins at School," is the name of the fourth book, and in that I had the pleasure of telling you the many good times they had there. Later on they went to "Snow Lodge" and helped solve a mystery, while on the houseboat, Bluebird, where they spent one vacation, they found a "stowaway," and, if you want to know what that is, I advise you to read the book.

"The Bobbsey Twins at Meadow Brook," is the name of the book just before this present one. On the farm of Uncle Daniel Bobbsey the twins had had a most glorious time, and they were on their way home in the train when the fresh air children got aboard, and Tommy Todd told the story about his lost father. Then had come the sudden stop, and Bert had seen the men with guns outside the train.

"I tell you they are robbers, Nan," Bert whispered to his sister. "Look, one of 'em has a mask on his face."

"That's so," agreed Nan. "Oh, I wonder what it is!"

"Don't be afraid!" exclaimed Bert. "I guess they won't come in this car. Father won't let them."

By this time Flossie and Freddie had also seen the masked men with their guns standing along the track, and Freddie cried:

"Oh, look! It's just like Hallowe'en. They've got false faces on!"

Many in the car laughed at this.

CHAPTER III

SNAP AND SNOOP

The train on which the Bobbsey twins were coming back from the country had now been stopping for several minutes. There was no sign of a station on either side of the track, as could be told by those who put their heads out of the opened windows. And Mr. Bobbsey had not come back.

"I wonder if anything has happened," remarked Mrs. Bobbsey.

"I'll go and find out, Mother," offered Bert, getting up from his seat.

"No, indeed, I can't let you!" his mother answered. "Your father would not like it. He may be back any moment."

"I don't believe anything much has happened, ma'am," said a man across the aisle from Mrs. Bobbsey. "I can see some men up near the engine, but they are talking and laughing."

"Then they aren't robbers," said Freddie to his older brother Bert, "'cause robbers wouldn't laugh."

"Well, if they're not train robbers why have they guns and false faces on?" asked Bert.

"Maybe they're just making believe—same as when we have pretend-plays," put in
