The steamboat was not slow in making its appearance on the lakes. In 1818, while it was still an experiment on the seaboard, one of these craft appeared on Lake Erie. The "Walk-in-the-Water" was her name, suggestive of Indian nomenclature and, withal, exceedingly descriptive. She made the trip from Buffalo to Detroit, not infrequently taking thirteen days. She was a side-wheeler, a model which still holds favor on the lower lakes, though virtually abandoned on the ocean and on Lake Superior. An oil painting of this little craft, still preserved, shows her without a pilot-house, steered by a curious tiller at the stern, with a smokestack like six lengths of stovepipe, and huge unboxed wheels. She is said to have been a profitable craft, often carrying as many as fifty passengers on the voyage, for which eighteen dollars was charged. For four years she held a monopoly of the business. Probably the efforts of Fulton and Livingstone to protect the monopoly which had been granted them by the State of New York, and the determination of James Roosevelt to maintain what he claimed to be his exclusive right to the vertical paddle-wheel, delayed the extension of steam navigation on the lakes as it did on the great rivers. After four years of solitary service on Lake Erie, the "Walk-in-the-Water" was wrecked in an October storm. Crowded with passengers, she rode out a heavy gale through a long night. At daybreak the cables parted and she went ashore, but no lives were lost. Her loss was considered an irreparable calamity by the settlers at the western end of the lake. "This accident," wrote an eminent citizen of Detroit, "may be considered one of the greatest misfortunes which has ever befallen Michigan, for, in addition to its having deprived us of all certain and speedy communication with the civilized world, I am fearful it will greatly check the progress of immigration and improvement."

It is scarcely necessary to note now that the apprehensions of the worthy citizen of Michigan were unfounded. Steam navigation on the lakes was no more killed by the loss of the pioneer craft than was transatlantic steam navigation ended by the disapproving verdict of the scientists. Nowhere in the world is there such a spectacle of maritime activity, nowhere such a continuous procession of busy cargo-ships as in the Detroit River, and through the colossal locks of the "Soo" canals. In 1827 the first steamboat reached the Sault Ste. Marie, bearing among her passengers General Winfield Scott, on a visit of inspection to the military post there, but she made no effort to enter the great lake. About five years later, the first "smoke boat," as the Indians called the steamers, reached Chicago, the pigmy forerunner of the fleet of huge leviathans that all the summer long, nowadays, blacken Chicago's sky with their torrents of smoke, and keep the hurrying citizens fuming at the open draw of a bridge. All side-wheelers were these pioneers, wooden of course, and but sorry specimens of marine architecture, but they opened the way for great things. For some years longer the rushing torrent of the Ste. Marie's kept Lake Superior tightly closed to steamboats, but about 1840 the richness of the copper mines bordering upon that lake began to attract capital, and the need of steam navigation became crying. In 1845 men determined to put some sort of a craft upon the lake that would not be dependent upon the whims of wind and sails for propulsion. Accordingly, the sloop "Ocean," a little craft of fifteen tons, was fitted out with an engine and wheels at Detroit and towed to the "Soo." There she was dragged out of the water and made the passage between the two lakes on rollers. The "Independence," a boat of about the same size, was treated in the same way later in the year. Scarcely anything in the history of navigation, unless it be the first successful application of steam to the propulsion of boats is of equal importance with the first appearance of steamboats in Lake Superior. It may be worth while to abandon for a moment the orderly historical sequence of this narrative, to emphasize the wonderful contrast between the commerce of Lake Superior in the days of the "Independence" and now—periods separated by scarcely sixty years. To-day the commerce of that lake is more than half of all the great lakes combined. It is conducted in steel vessels, ranging from 1500 to 8500 tons, and every year sees an increase in their size. In 1901 more than 27,000,000 tons of freight were carried in Lake Superior vessels, a gain of nearly 3,000,000 over the year before. The locks in the "Soo" canal, of which more later, have twice had to be enlarged, while the Canadian Government has built a canal of its own on the other side of the river. The discovery and development of the wonderful deposits of iron ore at the head of the lake have proved the greatest factors in the upbuilding of its commerce, and the necessity for getting this ore to the mills in Illinois, Ohio, and Pennsylvania, has resulted in the creation of a class of colossal cargo-carriers on the lake that for efficiency and results, though not for beauty, outdo any vessel known to maritime circles.

At the present time, when the project of a canal to connect the Atlantic and Pacific oceans at the Central American Isthmus has almost passed out of the sphere of discussion and into that of action, there is suggestiveness in the part that the canal at the "Soo" played in stimulating lake commerce. Until it was dug, the lake fleets grew but slowly, and the steamers were but few and far between. Freight rates were high, and the schooners and sloops made but slow passages. From an old bill, of about 1835, we learn that freight rates between Detroit and Cleveland, or Lake Erie points and Buffalo, were about as follows: Flour, thirty cents a barrel; all grain, ten cents a bushel; beef, pork, ashes, and whisky, thirteen cents a hundred pounds; skins and furs, thirty-one cents a hundred weight; staves, from Detroit to Buffalo, $6.25 a thousand. In 1831 there were but 111 vessels of all sorts on the lakes. In five years, the fleet had grown to 262, and in 1845, the year when the first steamer entered Lake Superior, to 493. In 1855, the year the "Soo" canal was opened, there were in commission 1196 vessels, steam and sail, on the unsalted seas. Then began the era of prodigious development, due chiefly to that canal which Henry Clay, great apostle as he was of internal improvements, said would be beyond the remotest range of settlements in the United States or in the moon.

At the head of Lake Superior are almost illimitable beds of iron ore which looks like rich red earth, and is scooped up by the carload with steam shovels. Tens of thousands of men are employed in digging this ore and transporting it to the nearest lake port—Duluth and West Superior being the largest shipping points. Railroads built and equipped for the single purpose of carrying the ore are crowded with rumbling cars day and night, and at the wharves during the eight or nine months of the year when navigation is open lie great steel ships, five hundred feet long, with a capacity of from six thousand to nine thousand tons of ore. Perhaps in no branch of marine architecture has the type best fitted to the need been so scientifically determined as in planning these ore boats. They are cargo carriers only, and all considerations of grace or beauty are rigidly eliminated from their design. The bows are high to meet and part the heavy billows of the tempestuous lakes, for they are run as late into the stormy fall and early winter season as the ice will permit. From the forward quarter the bulwarks are cut away, the high bow sheltering the forecastle with the crews, while back of it rises a deck-house of steel, containing the officers' rooms, and bearing aloft the bridge and wheel-house. Three hundred feet further aft rises another steel deck-house, above the engine, and between extends the long, flat deck, broken only by hatches every few feet, battened down almost level with the deck floor. During the summer, all too short for the work the busy iron carriers have to do, these boats are run at the top of their speed, and on schedules that make the economy of each minute essential. So they are built in such fashion as to make loading as easy and as rapid as possible. Sometimes there are as many as fourteen or sixteen hatches in one of these great ships, into each of which while loading the ore chutes will be pouring their red flood, and out of each of which the automatic unloaders at Cleveland or Erie will take ten-ton bites of the cargo, until six or seven thousand tons of iron ore may be unloaded in eight hours. The hold is all one great store-room, no deck above the vessel's floor except the main deck. No water-tight compartments or bulkheads divide it as in ocean ships, and all the machinery is placed far in the stern. The vessel is simply a great steel packing-box, with rounded ends, made strong to resist the shock of waves and the impact of thousands of tons of iron poured in from a bin as high above the floor as the roof of a three-story building. With vessels such as these, the cost of carrying ore has been reduced below the level of freight charges in any part of the world.

Yet comfort and speed are by no means overlooked. The quarters of the officers and men are superior to those provided on most of the ocean liners, and vastly better than anything offered by the "ocean tramps." Many of the ships have special guest-cabins fitted up for their owners, rivalling the cabins de luxe of the ocean greyhounds. The speed of the newer ships will average from fourteen to sixteen knots, and one of them in a season will make as many as twenty round trips between Duluth and Cleveland. Often one will tow two great steel barges almost as large as herself, great ore tanks without machinery of any kind and mounting two slender masts chiefly for signaling purposes, but also for use in case of being cut adrift. For a time, the use of these barges, with their great stowage capacity in proportion to their total displacement, was thought to offer the cheapest way of carrying ore. One mining company went very heavily into building these craft, figuring that every steamer could tow two or three of them, giving thus for each engine and crew a load of perhaps twenty-four thousand tons. But, seemingly, this expectation has been disappointed, for while the barges already constructed are in active use, most of the companies have discontinued building them. Indeed, at the moment of the preparation of this book, there were but two steel barges building in all the shipyards of the great lakes.

Another form of lake vessel of which great things were expected, but which disappointed its promotors, is the "whaleback," commonly called by the sailors "pigs." These are cigar-shaped craft, built of steel, their decks, from the bridge aft to the engine-house, rounded like the back of a whale, and carried only a few feet above the water. In a sea, the greater part of the deck is all awash, and a trip from the bridge to the engine-house means not only repeated duckings, but a fair chance of being swept overboard. The first of these boats, called the "101," was built in sections, the plates being forged at Cleveland, and the bow and stern built at Wilmington, Del. The completed structure was launched at Duluth. In after years she was taken to the ocean, went round Cape Horn, and was finally wrecked on the north Pacific coast. At the time of the Columbian Exposition, a large passenger-carrying whaleback, the "Christopher Columbus," was built, which still plies on Lake Michigan, though there is nothing discernible in the way of practical advantage in this design for passenger vessels. For cargo carrying there would seem to be much in the claims of their inventor, Alexander McDougall, for their superior capacity and stability, yet they have not been generally adopted. The largest whaleback now on the lakes is named after Mr. McDougall, is four hundred and thirty feet over all, fifty feet beam, and of eight thousand tons capacity. She differs from the older models in having a straight stem instead of the "pig's nose."
