"And maybe it's a collection of—money!" said Janet.

"That would be very fine!" laughed her father. "But though Uncle Toby is well off, I hardly think he has a collection of money lying around his old mansion. However, I suppose I must go and see what it is the queer fellow wants me to take charge of for him."

"May we go?" chorused Ted and Janet again.

"Oh, I suppose so," agreed their father, and this was better than the "I'll see," of their mother.

"Me tum too!" declared Trouble. He never wanted to be left behind.

"We'll all take an auto trip over to Pocono to-morrow and see what Uncle Toby has," decided Mr. Martin.

Accordingly, the next day, Mr. Martin left his manager in charge of the store, and, in the comfortable family automobile, the Curlytops and their father, mother and Trouble—not forgetting Skyrocket, the dog—started off.

It was just as fine a day as the previous one, when Trouble had sailed down the brook. The grass was green, the birds sang, and the wind blew gently in the trees.

"Oh, it's summer, and there's no school and well have lots of fun!" sang Janet.

"Maybe we'll have fun with what we find at Uncle Toby's house," suggested Ted.
