We get an admirable idea of what these early steamships were from Dickens's account of this same _Britannia_, which was the vessel he crossed to America in on his first visit to that country in 1842. In one of his letters to John Forster, describing a storm they were overtaken by, he unconsciously reflects the wondering regard with which the world still viewed the triumphant achievements of the marine engine. 'For two or three hours,' he writes, 'we gave it up as a lost thing. This was not the exaggerated apprehension of a landsman merely. The head-engineer, who had been in one or the other of the Cunard vessels since they began running, had never seen such stress of weather; and I afterwards heard Captain Hewitt say that nothing but a steamer, and one of that strength, could have kept her course and stood it out. A sailing-vessel must have beaten off and driven where she would; while through all the fury of that gale they actually made fifty-four miles headlong through the tempest, straight on end, not varying their track in the least.' What would the skipper of one of the modern 'Atlantic greyhounds' think of such a feat? And, more interesting speculation still, what must Dickens himself have thought of the performances he lived to witness as against this astonishing accomplishment on the part of the old _Britannia_? There exists a tendency to ridicule the early steamers as they appear in portraits, with their huge paddle-boxes; tall, thin, dog-eared funnels; and heavily-rigged masts, as though their engines were regarded as quite auxiliary to their sail-power, and by no means to be relied upon. Contrasted with some of the leviathans of the present day, the steamers of half a century ago are no longer calculated to strike an awe into the beholder; but, in truth, some very fine vessels were built whilst the marine engine was still quite in its infancy. In a volume of the _Railway Magazine_ for 1839 is an account of what are termed colossal steamers. 'An immense steamer,' runs the description, 'upwards of two hundred feet long, was lately launched at Bristol, for plying between England and America; but the one now building at Carling & Co.'s, Limehouse, for the American Steam-navigation Company, surpasses anything of the kind hitherto made. She is to be named after our Queen, the _Victoria_; will cost from eighty to one hundred thousand pounds, has about one hundred and fifty men now employed daily upon her, and is expected to be finished in November next. The extreme length is about 253 feet; but she is 237 feet between the perpendiculars, 40-1/4 feet beam between the paddle-boxes, and twenty-seven feet one inch deep from the floor to the inner side of the spar-deck. The engines are two, of 250 horse-power each, with six feet four inch cylinders, and seven feet stroke. They are to be fitted with Hall's patent condensers, in addition to the common ones. She displaces at sixteen feet 2740 tons of water; her computed tonnage is 1800 tons.
