Stationing himself on an elevated part of the deck, he kept a close watch on the movements of the vessel, observing the tossing to which she was subjected by the waves, the extent of the dip when she sank into a trough, the height of elevation when lifted on the summit of a wave, and calculating in his mind how all this would tell on the paddle-wheels. Through the roughest of the storm, when the vessel was pitching worst, and the wind blowing at its fiercest, he kept his place on deck, regardless of the drenching spray and the blast that almost carried him off his legs. When at length he had satisfied himself by the observation of his own eyes and inquiries of the captain and crew, that there was nothing in the voyage which a steamer could not encounter, he retired contentedly to his cabin, leaving everybody astonished at his strange curiosity respecting the effect of rough weather on the ship. Not long after David Napier started the _Rob Roy_ steam-packet between Greenock and Belfast, and afterwards between Dover and Calais. In the course of two or three years more he had established steam communication between Holyhead and Dublin, Liverpool and Greenock, and various other parts. The length of each unbroken passage was then considered the great difficulty; but as steamers got improved both in form and machinery, passages of greater length were successfully accomplished. Steamers traversed in all directions the German Ocean, the Mediterranean, the Baltic, and, in short, all the waters on the eastern side of the Atlantic; and were in use upon all the rivers and lakes of any size in Europe. At length, in 1836, the startling project was set on foot of superseding the far-famed New York and Liverpool packet ships by a fleet of steam-ships. Before this the _Savannah_, a steam vessel of 300 tons, had, in 1819, crossed from New York to Liverpool in twenty-six days, partly with sails and partly with steam; and another steam vessel had, in 1825, made the voyage from England to Calcutta; but one swallow does not make a summer, and many learned folks, on both sides of the Atlantic, shook their heads doubtfully at the daring scheme of regular steam communication across 13,000 miles of ocean. The experiment was to be made, however; and on the 4th April 1838, the _Sirius_, of 700 tons and 320 horse power, sailed from Cork for the far West. Four days after the _Great Western_ followed in her wake from Bristol.
