"Good morning, Billy," said the chief, good-naturedly. "You are making an early start, I see; are you busy?" "No, sir," answered Mr. Davids; "I can take you gentlemen wherever you want to go." "Not to-day, Billy; but I have a friend here who wants to talk to you, and you may find it to your interest to tell him what he wishes to know." Manning stepped forward and stated, in as few words as possible, what he desired, and at length displayed the inevitable photograph. Davids recognized it at once, as a "party" who had engaged him to take himself and a woman from the hotel, to a resort some distance from the city, known as the "Half-way House." He performed this duty, and later in the day, after waiting several hours, the man had given him ten dollars and sent him back to the hotel to pay his bill and to obtain his valise. After performing this service, he returned to the Half-way House, and waited there until dark, when Duncan came out alone, and was driven to the Northern Pacific depot. Arriving here, he paid the hackman quite liberally and dismissed him, saying that he was going to leave town on the next train westward. "Have you any idea where he was going?" asked Manning. "I think he went to Minneapolis, for he asked me if that road would take him there, and I saw him get aboard the train for that city;" answered the driver. This was all that Davids could tell; and after remunerating him for his trouble, Manning left him to finish his preparations for the day. Here was the very information he wanted, and he had struck the trail again. Anxious to pursue his journey, Manning invited the chief to breakfast with him; after which, finding he could leave in a very short time, he bade the courteous and valuable officer good-by, and was soon on his way to Minneapolis, there to commence again the trail of the fleeing burglar.
