The year 1838 was signalised, among other things, by some events showing the rapid change which science was making in the habits of society. On the 23rd of April, the _Great Western_ steamer arrived at New York, after a voyage of fifteen clear days. This famous ship, and the _Sirius_, whose voyage was simultaneous almost to a day, were the first vessels which had crossed the Atlantic by steam-power alone, sails having been used in combination with steam on previous occasions. The _Great Western_ was in those days the largest steamer ever known, her tonnage being equal to that of the largest merchant-ships. She was built at Bristol, and sailed from that port on the 7th of April. When she entered the harbour of New York, she had still a surplus of one hundred and forty-eight tons of coal on board, and the problem was solved as to whether a steamer could be constructed large enough to carry sufficient fuel for so long a voyage. The size, tonnage, and speed of this historic vessel have been greatly surpassed in later times; but the fact of a ship crossing the Atlantic in fifteen days was a very genuine astonishment to the people of 1838. Two years later (1840), the Cunard line of steamers was established at Liverpool, which soon entirely eclipsed Bristol as the great commercial port on the western side of England, and as the packet-station for the American service. Another interesting feature of the year 1838 was the opening of the London and Birmingham Railway throughout its entire length. The precise date was the 17th of September, and thenceforward the railway system progressed rapidly. The line in question, however, was not the first that had been placed at the disposal of the public. The original railway for the use of passengers was that constructed by Edward Pease and George Stephenson between Stockton and Darlington, and opened on the 27th of September, 1825. The next was the Liverpool and Manchester Railway, commenced in October, 1826, and opened on the 15th of September, 1830--on which occasion, Mr. Huskisson, a prominent statesman of the time, was accidentally killed. Nevertheless, the development of the system is associated almost entirely with the reign of Queen Victoria, and we hardly think of railways as belonging, even in their inception, to an earlier period.
