We have entered thus at considerable length into this voyage, because, besides being the first steam sea-voyage, it serves to exhibit very distinctly how great and how rapid has been the progress of steam-navigation within the last fifty years. In reading such an account as this, in these days of "ocean mail-steamers" and "Great Easterns," we can scarcely believe that in it reference is made, not to the middle ages, but to the year 1813. OCEAN-STEAMERS. After that momentous era when steam was first successfully applied to useful purposes, human progress and improvement in all departments of science and art seemed to have been hooked on to it, and to have thenceforth rushed roaring at its tail, with truly "railroad speed," towards perfection! Scarce had the first model steamboat splashed with its ungainly "blades" the waters of a pond, than river traffic by means of steamboats began. And no sooner had this been proved to be a decided success, than daring schemes were laid to rush over the ocean itself on wheels. Men were not long about it, after the first start was made. Their intellectual steam was up, and the whirl of inventive effort racked the brains of engineers as the wheels of their steamboats tortured the waters of the deep. And here again the name of Fulton comes into notice. Early in 1814 he conceived the idea of constructing a steam-vessel of war, which should carry a strong battery with furnaces for red-hot shot. Congress authorised the building of such a ship, and before the end of the same year it was launched. Fulton died the following year, but the fame of that enterprising engineer will never die. The new vessel received the rather quaint title of _Fulton the First_. She consisted of two boats joined together. Those who were appointed by Congress to examine her and report, gave the following account of this curious man-of-war:
