The grand Ship Canal, with its stone banks of about eighty feet width and three locks, transports the largest tonnage around these rapids. This great work was completed in 1857 by the contractors, Erastus Corning, of New York, Fairbanks, and others, for a contract price of seven hundred and fifty thousand acres of land, chiefly mineral, in the State of Michigan. During our steamer's canal passage of about two hours, we were interested by the picturesque scenery, untenanted save by the wigwam and the bark canoe. As usual, upon the arrival of the steamer, the long canoe, steadily held by a single boy and paddle, in a current swift as the Niagara, shoots out into the Saut, while the Indian, standing erect in the canoe, poising his harpoon and scrap net, strikes or swoops in the large and delicious white fish, assured of a capacious basketful and more, before the steamer leaves the canal.

And thus we floated onward to the bosom of great Superior.

Our course was along the St. Mary outlet, northwesterly toward White Fish Point, on the main south shore, projecting far out into the lake. We were hence carried miles away from sight of the famed-pictured rocks or of any land. Tending southerly and still westward, we steamed on over the dark waters, during a serene night, until daylight showed us the beautiful town of Marquette. Scarce seven years old, the fruit of the iron mining in its vicinity, it spreads its neat white cottages around the crescent of its bay and river on an amphitheatre of hills. The rail train destined to Bai de Noc, on Green Bay, and finished to Marquette Mines, in all some eighteen miles, was starting upon our arrival. Marquette, though so young, a mere group of cottages, fronting a wilderness, from its rich mines of the best iron, has become at once a scene of industry and large outlay of capital; while the beauty of its position and its unrivalled climate, surpassing all others on Lake Superior, have already made it the most attractive summer resort, as well for the pleasure traveller as the pulmonary invalid. Its climate, without the sea air, has a cool, silken softness, reminding one of Newport, Rhode Island. It is more equable and certain; the summer average is 66°, and the winter 41°; while the lake wind and evaporation secure it from the rapid changes of the sea shores.

Marquette is the lake port and entrepot of the short range of iron mountains which adjoin their sisters, known as the Porcupine Mountains, in whose depths lies the famous copper ore, not unmixed with silver and other precious deposits. This great mountain fortress extends from Marquette to Montreal River, beyond Ontonagon, the western boundary of the State of Michigan, in a line of about twelve to eighteen miles south of the lake, and often approaches two thousand feet in height, lifting its forest sides in constant view for more than two hundred miles. Leaving Marquette and the iron range at 7 A.M., on the 3d of August, we sailed for Portage, the first harbor in the copper mountains, arriving about noon.

Portage is a shallow bay or mouth of the river of the same name, on the east shore of Keewaiwonah Promontory, or, as it is commonly called, Keweenaw Point. The mines and town of Portage lie at the mountains, about sixteen miles inland. A few huts were the only signs of settlement at the bay. Tugs landed the freight and passengers, and we soon left the wooded bank for the broad expanse of the lake, turning the head of the promontory, and at 5 P.M. reaching Copper Harbor on its northwest shore. Here we lay till morning. The village is small, at the base of a lower range of mineral mountains, spurs of the main chain.

The Clarke Copper Mine is within two miles of the wharf. This mine, like many others, has had many owners. It had just gone through the experiments of a French company, which expended its capital, as alleged, in building fine roads, bridges, and residences for its agents, while the mining had scarcely reached one hundred and twenty feet deep, and then employed only six Frenchmen as its miners, whose ore product was little over three per cent. of copper. In other hands, perhaps, it may now yield a better reward.

We were much amused with the description given by these Frenchmen of the mishaps of their ill-directed enterprise. Persistent as Chinese, resembling many others of the French nation in their ignorance of our country, language, or customs, they had passed through many droll blunders, which rendered their narrative highly entertaining.

Copper Harbor, although so small, only then claiming about seventy legal voters in the entire township, including the mines, was promised the unusual treat of a political address that evening, as duly placarded, from a gentleman, who was then candidate for Governor of Michigan, and came in our boat. The apathy and indifference of the free and enlightened electors of Copper Harbor were remarkable. A small, dingy room, adjoining the only store, was the destined arena; and therein, dimly lighted by some tallow candles, long sat the candidate—alone: a rejected Timon, whose reflections were never published. The only interest taken in the meeting (that came under my notice) was an anxious inquiry by the owner of the building for his rent and expense of candles, etc., payment of which was alleged to have been refused by the candidate.

Singularly happy Copper Harbor! your contented equanimity is unruffled by all the stormy strife of politicians.

Its lake front is graced by a fort, now and long since a water-cure establishment. All these Western forts, erected many years ago, seem not intended for offence, but rather as stockades or blockhouses of shelter from the Indians. They are arranged as extensive tenements within, pierced for musketry, and only in some cases with terraces for cannon. These frontier forts, long the dwelling of the hunter or his family in the wilderness, were guarded by the company of troops who protected the settlers and maintained the sovereignty of our flag and nation over these remote wilds. They are always placed in the most eligible and commanding positions, and seem as if by design to have secured the settlement of these points, which in all cases have become the thronged cities or favorite towns of the ever-growing West. Thus, in Europe, the ancient Roman fortified camps on their frontiers founded Cologne, Chester, Vienna, Milan, Verona, and other cities, once their military outposts against barbarism.
