Amid scenery increasing in wildness and grandeur, the train pursues its tortuous course; through Iron Ridge Tunnel, near which the track forms an almost perfect letter S; across innumerable ravines; along rocky shelves and through deep cuttings, until at last it enters the eastern portal of the Mullan Tunnel. A few minutes later the traveler is looking out upon the grassy hills and pleasant valleys of the Pacific slope, the approach to the tunnel from the west presenting a singular contrast to the savage grandeur that distinguishes the approach from the east.

Following the valley of the Little Blackfoot, the train presently arrives at Garrison, where passengers desirous of visiting the most flourishing mining city on the American continent, if not in the world, must change cars.

“The most flourishing mining city on the American continent, if not in the world!” exclaims the reader. Even so; and yet we are not in Nevada, nor yet in Colorado; and, besides, the former is about played out; and, as for Leadville, every one remembers the disasters that overtook her, culminating, as they did, in the failure of all her four banks. The city is Butte, that, at the last United States census, had a population of only 3,363, but now claims six times that number, and has a monthly mining pay-roll of $620,000.

The line from Garrison runs through the beautiful Deer Lodge valley, in which are many fine farms. Deer Lodge City, the judicial seat of the county, is pleasantly situated 4,546 feet above sea-level. Being well laid out, it presents, with its wide streets and handsome public buildings, an exceedingly attractive appearance.

It is at the head of this valley, on the western slope of the main range of the Rocky Mountains, and fifteen miles from the Pipestone Pass, that there has been witnessed, during the last three or four years, that rapid growth of population and wealth that is without parallel, even in the marvelous annals of mining. Here, encompassed on three sides by lofty ranges of mountains, Butte pours forth the smoke of its innumerable furnaces; for not only is its production of silver so great that it has come to be designated the “Silver City,” but its copper mines are such as to give employment to the most extensive smelting works in the United States. Its total production during 1885, valued at $15,000,000, viz., $5,000,000 worth of bullion and $10,000,000 worth of copper matte, was twice that of Utah, and three times that of Nevada. It also exceeded that of the whole of California, or the combined production of Idaho, New Mexico and Arizona.

The leading silver mines of the district are the Alice, Moulton, Lexington and Silver Bow, which alone employ 210 stamps and produce 230 tons of ore daily. The magnificent appliances of the Alice mine, including the great Cornish pump that cost $40,000, are the wonder of every visitor. The process of reduction, here as elsewhere, is somewhat complex, especially in the case of the baser ores, being in part chemical and in part mechanical. It involves the crushing of the ore to powder, under the pressure of enormous bars of iron, weighing 900 pounds each, and known as “stamps,” and its subsequent roasting in large, hollow cylinders, salt being largely employed in the former, and quicksilver in the latter, stage of the operation. The roasting mills of the Alice mines treat 100 tons of ore per day, and their bullion product approaches $100,000 per month.

The great Lexington property, which has produced $1,000,000 per annum for four years, is owned by a French company. It claims to be the most complete mine in the entire West, and it is certainly one of the richest and most extensive.

The Moulton and Silver Bow have a daily capacity of forty and thirty tons of ore respectively. They are magnificent properties, well developed and exceedingly productive. The former makes the proud boast of working its ore to a higher percentage of its value than any other mill in the district.

But it is the copper mines and smelters that represent the largest capital; give employment to the greatest number of men; have the largest production, both in tonnage and aggregate value; and, it may be added, make the most smoke.

At the head of the rich and powerful companies engaged in this industry, stands the Anaconda,—its mine at Butte, the greatest copper property in America; its smelting works, at the neighboring town of Anaconda, the largest of their kind in the world. Sold, five years ago, for an amount that would not now be more than sufficient to pay its employés a week's wages, its property is roughly estimated to be worth $15,000,000. With certain contemplated additions to its smelting capacity, it will handle daily 1,200 tons of ore, yielding 180 tons of matte, or 108 tons of pure copper. Its entire machinery run by water-power, it yet requires for its furnaces no less than 180 cords of wood per day; in view of which enormous consumption it is stated to have recently let a contract for 300,000 cords, representing upward of $1,000,000. Second only to this gigantic concern, is the Parrott Company, whose total matte output for 1884 was 14,856,323 pounds, containing 9,324,805 pounds of pure copper, valued, including its silver contents, at about $1,250,000. With largely increased capacity, its production of pure copper will probably have reached 15,000,000 pounds in the year just drawing to a close. Among other leading companies, may be mentioned the Montana, owning some of the richest and most steadily productive mining property in process of development; Clark's Colusa, said to have in sight, above the 300-foot level, at least 150,000 tons of valuable ore; and the Bell and Colorado, two of the richest copper-silver mines in the district.
