And then a welcome voice answered:

“I’m coming! I’m coming!”

So, while some one is coming to the rescue, I will take just a few moments to tell my new readers something about the children who are to have adventures in this story.

Those of you who have read the other books of the series will remember that in the first volume, called “The Bobbsey Twins,” I told you of Flossie and Freddie, and Bert and Nan Bobbsey, who lived with their father and mother in the eastern city of Lakeport, near Lake Metoka. Mr. Richard Bobbsey owned a large lumberyard, where the children were wont often to play. As I have mentioned, Flossie and Freddie, with their light hair and blue eyes, were one set of twins—the younger—while Nan and Bert, who were just the opposite, being dark, were the older twins.

The children had many good times, about some of which I have told you in the first book. Dinah Johnson, the fat, jolly cook, always saw to it that the twins had plenty to eat, and her husband, Sam, who worked about the place, made many a toy for the children, or mended those they broke. Almost as a part of the family, as it were, I might mention Snap, the trick dog, and Snoop, the cat. The children were very fond of these pets.

After having had much fun, as related in my first book, the Bobbsey twins went to the country, where Uncle Daniel Bobbsey had a big farm at Meadow Brook. Later, as you will find in the third volume, they went to visit Uncle William Minturn at the seashore.

Of course, along with their good times, the children had to go to school, and you will find one of the books telling what they did there, and the fun they had. From school the Bobbsey twins went to Snow Lodge, and then they spent some time on a houseboat and later again went to Meadow Brook for a jolly stay in the woods and fields near the farm.

“And now suppose we stay at home for a while,” Mr. Bobbsey had said, after coming back from Meadow Brook.

At first the twins thought they wouldn’t like this very much, but they did, and they had as much fun and almost as many adventures as before. After that they spent some time in a great city and then they got ready for some wonderful adventures on Blueberry Island.

Those adventures you will find told about in the book just before this one you are now reading. The twins spent the summer on the island, and many things happened to them, to their goat and dog, and to a queer boy. Freddie lost some of his “go-around” bugs, and there is something in the book about a cave,—but I know you would rather read it for yourself than have me tell you here.
