"Good for Sandy!" exclaimed Ned. "He treated us pretty mean once, but he's making up for it now."

"Yes, it was a good stroke of business the day we helped him load the overturned sleigh," said Fenn, referring to an incident of the previous winter, as related in "The Darewell Chums in the City."

"What are you going to do?" asked Frank quietly.
