The exhibition, of course, did not confine itself to the steam era alone. It even had a model of an Egyptian vessel, which was exhibited by the Liverpool Library Society, as taken from Thebes, and estimated to date about 1,500 years B.C., and which Moses himself might thus have seen. It was a long stretch, however, to the next in date, as no others antedated 1700 A.D. There were many of the handsome and dignified eighteenth-century men-of-war, built at a time when men began to preserve a record of their work in the miniature ships which are now esteemed an essential addition to almost every vessel of importance put afloat. Firms now exist whose only business it is to make the various minute fittings—the ports, chains, anchors, blocks, etc.—of the Liliputian craft, so that every detail of the original is given with an exact verisimilitude in very often most beautiful and elaborate work. It would have been very interesting had the early struggles of the steamboat been thus illustrated _in extenso_, but there is nothing of its concrete history earlier than a small model of the original Comet, built by Henry Bell, at Glasgow, in 1812, and so named because of the extraordinary comet of that year, and the engines of her successor, built in 1820. These recall, however, the vessel which was the first steamer engaged in passenger traffic in Europe, and are thus worthy of honor. In looking over the beautiful array of models then exhibited, which thus represented almost every stage of progress in British steamship building, from the Comet onward, one could not help regretting that an effort had not been made by our government to bring together models, of which there must have been some, at least, available, illustrative of our earlier practice, particularly as there is much in it peculiar to us, and which would have been most interesting to the great public which visited the exhibition. Models of the Clermont; of the Stevens experimental screw boat; a later Mississippi steamer; the Savannah—the first vessel using steam which ever crossed the Atlantic; the Washington, the pioneer of regular transatlantic steam traffic under our flag; the Adriatic; the Hudson River and great Sound steamers of to-day, would, apart from any war-ship models of interest which could have been sent, have made a most interesting and attractive collection. The only things, however, which were visible were the drawings of a New York ferry-boat (the type of which, by the way, we owe to Fulton), so placed as to be scarcely discoverable. These boats are so typical, so different from anything found in Europe, and so interesting to any student of steam ferriage as a thorough adaptation of means to an end, that a complete model of the boat and its ferry slip would have been a most satisfactory addition.
