In the next book, "Bunny Brown and His Sister Sue at Aunt Lu's City Home," I told the story of the two children going to the big city of New York, and of the queer things they saw and the funny things they did while there.

Bunny and Sue had played together as long as they could remember. Bunny was about six or seven years old and Sue was a year younger. Wherever one went the other was always sure to be seen, and whatever Bunny did Sue was sure to think just right. Every one in Bellemere knew Bunny and Sue, from old Miss Hollyhock to Wango, a queer little monkey owned by Jed Winkler the sailor. Wango often got into mischief, and so did Bunny and Sue. And the children had much fun with Uncle Tad who loved them as if they were his own.

After Bunny and Sue had come back from Aunt Lu's city home the weather was very warm and Daddy Brown thought of camping in the woods. So that is what they did, and the things that happened are related in the fifth book in the series, called "Bunny Brown and His Sister Sue at Camp Rest-a-While." For that is what they named the place where the tents were set up under the trees on the edge of the big woods and by a beautiful lake.

Neither Bunny nor Sue had ever been to the end of these big woods, nor had Mr. Brown, though some day he hoped to go. The summer was about half over. Mrs. Brown liked it so much that she said she and the children would stay in the woods as long as it was warm enough to live in a tent.

And now, this afternoon, Mr. Brown had come home from the city with the two queer big bundles, and the children were so excited thinking what might be in them that they watched every mouthful of tea Mr. Brown sipped.

"When will you be ready to show us?" asked Sue.

"Please be quick," begged Bunny. "I—I'm gettin' awful anxious."

"Well, I guess I can show you now," said Mr. Brown. "Bring me the heaviest package, Bunny."

It was all the little boy could do to lift it from the chair, but he managed to do it. Slowly Mr. Brown opened it. Bunny saw a flash of something red and shining.

"Oh, it's a fire engine!" he cried.
