Before Jet could turn his attention to the tariff again the boy at the desk called loudly: "Number forty-eight!" and he went forward quickly, well pleased that something had occurred to break the monotony.

A summons had come from one of the hotels near by, and on answering it he found nothing of more importance than to carry a letter to a certain house in the immediate vicinity, but to Jet it was particularly agreeable work, since he was given ten cents more than the regular fee.

"If all the messages turn out like this one I shall have a mighty good thing of it," he said to himself, in a tone of satisfaction as he returned to the station.
