It is scarcely ten years that mining has been properly commenced in that remote region. At that time it was difficult, on account of the rapids of St. Mary's River, to approach it by water with large craft. Being more than a thousand miles distant from the centre of the Union, destitute of all the requirements for the development of mines; every tool, every part of machinery, every mouthful of provisions had to be hauled over the rapids, boated along the shores for hundreds of miles to the copper region, and there often carried on the back of man and beast to the place where copper was believed to exist. Every stroke of the pick cost tenfold more than in populated districts; every disaster delayed the operations for weeks and months. The opening of the Saut Canal has changed all this and added a wonderful impetus to the business, the mining interests, and the development of the Lake Superior country. Nearly one hundred different vessels, steam and sail, have been engaged the past season in its trade, and the number of these is destined largely to increase year by year, an indication of the growth of business and the opening up of the country. For the growth in the copper interest we have only to refer to the shipments from that region year by year. These, in gross, are as follows: 1853 2,535 tons. 1854 3,500 " 1855 4,544 " 1856 5,357 " 1857 6,094 " 1658 6,025 " 1859 6,245 " The same facts of development would hold generally true, with regard to the other industrial interests of that vast country. It remains yet almost wholly "a waste, howling wilderness." At Marquette, Portage Lake, Copper Harbor, Eagle River, Eagle Harbor, and Ontonagon, and the mines adjacent, are the only places where the primeval forests have given place to the enterprise of man, and these in comparison with the whole extent of territory embraced in this region, are but mere insignificant patches. What this country may become years hence, it would defy all speculations now to predict, but there seems no reason to doubt that it will exceed the most sanguine expectations. The copper region is divided into three districts, viz., the Ontonagon, the most northern, the Keweenaw Point, the most eastern, and the Portage Lake, lying mostly below and partially between the range of the two. In the first are situated the Minnesota, the Rockland, the National, and a multitude of other mines of lesser note, profit, or promise. In the Cliff, the Copper Falls, and others. In the last are the Pewabic, Quincy, Isle Royale, Portage, Franklin, and numerous others. Each district has some peculiarities of product, the first developing the masses, while the latter are more prolific in vein-rock, the copper being scattered throughout the rock.
