The Long Trail Ended--Duncan Traced to his Lair--Caught at Last--The Escaping Burglar a Prisoner. Butte City is a rich mining village in Deer Lodge county in the territory of Montana, and is surrounded by high hills, which contain rich deposits of gold and silver which are taken from the quartz rock, and in the city are situated the furnaces and other appliances for extracting the precious metals from the rocks in which they are found. The population, although largely of a transient and adventurous character, is composed of a respectable, well-ordered community, many of whom have located permanently, and have labored for the advancement and success of the village. There are several stores, numerous hotels, many very handsome private dwellings, and a newspaper. Though not so large as Helena, by any means, it bids fair in time to rival her more successful neighbor, and the elements of success are found within her domain. The local government consists of a mayor and a city marshal, while the deputies of the latter official constitute the police force who maintain order in the city and protect the persons and property of the citizens. A substantial jail looks frowningly down upon one of the main thoroughfares, and altogether Butte City is as well-conducted and carefully managed a town as is to be found west of the Mississippi river. Within a few months a railroad, a branch of the Union Pacific road, had been completed, which placed the city in communication, both by rail and telegraph, with the larger towns and cities located in the South and East. After a hearty dinner and a refreshing bath, Manning left the hotel and sought the office of the city marshal. Here, as elsewhere, he was received with the utmost courtesy and kindness, and with a warm proffer of assistance, which the detective most gladly accepted. He detailed the circumstances of the robbery and his long pursuit of the escaping burglar, and also his strong belief that Duncan was now hiding in the city. The marshal fully coincided with his views, and promised to aid him to the utmost of his ability. He then furnished Manning with the address of Duncan's relative, and the detective started out to find the locality to which he had been directed. He soon discovered the place he was looking for, located on the second floor of one of the larger buildings in the city, and over the entrance was suspended the sign: GEORGE DUNCAN, CLOTHIER.
