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." [Illustration: THE "WHALEBACK"]
