"There is some one watching us!" cried John, excitedly, and half rising.

"Nonsense!" said Nelly; "it is only a cat. Sit down again."

This invitation was not to be declined. John sat down again, though

had concluded that Nelly's suggestion was a correct one, and they had
begun to chat quite unconcernedly, when they were again interrupted.
