"Seems like it," returned Bob; "but don't let us give up so easily. We'd better look sharp, or he will give us the slip yet."
The post-office was a rather imposing building, standing next to a department store. The entrances, running the entire length of the building, were fortunately all on one street. Therefore, when Nat reappeared, the two Ramblers were quickly on his track.
It is quite probable that had he been at all observant, the ex-Trailer would have seen either Bob or Sam, for, in their anxiety to always keep him in view, they often exposed themselves unnecessarily.
"He is not going back to the hotel, that is certain," said Bob to himself. "Ah! It begins to look interesting."
Nat stopped to speak to a policeman at a crossing.
"Must have asked for directions," muttered Bob.
The man in the blue uniform waved his arm, and Nat moved off at a brisk pace.
"It's getting warm now," chuckled Bob. "Wonder what he would think if he knew that we were at his heels? Whew! I'll have to be more careful. He almost caught me that time."
Along one street, down another, several times stopping to ask directions, Nat led them a merry chase.
In about half an hour, the outskirts of the city were reached. Rows of pretty residences, surrounded by gardens, extended a considerable distance, until, finally, fields, partly wooded, with a house here and there, came into view.
