The progress of physical science reacted upon metallurgy. Improved metallurgy, affording the possibility of a larger and bolder handling of masses of metal and other materials, reacted upon practical inventions. Machinery on a new scale and in a new abundance appeared to revolutionize industry.
In 1804 Trevithick adapted the Watt engine to transport and made the first locomotive. In 1825 the first railway, between Stockton and Darlington, was opened, and Stephenson’s “Rocket,” with a thirteen-ton train, got up to a speed of forty-four miles per hour. From 1830 onward railways multiplied. By the middle of the century a network of railways had spread all over Europe.
EARLY TRAVELLING ON THE LIVERPOOL AND MANCHESTER RAILWAY, 1833
Here was a sudden change in what had long been a fixed condition of human life, the maximum rate of land transport. After the Russian disaster, Napoleon travelled from near Vilna to Paris in 312 hours. This was a journey of about 1,400 miles. He was travelling with every conceivable advantage, and he averaged under 5 miles an hour. An ordinary traveller could not have done this distance in twice the time. These were about the same maximum rates of travel as held good between Rome and Gaul in the first century A.D. Then suddenly came this tremendous change. The railways reduced this journey for any ordinary traveller to less than forty-eight hours. That is to say, they reduced the chief European distances to about a tenth of what they had been. They made it possible to carry out administrative work in areas ten times as great as any that had hitherto been workable under one administration. The full significance of that possibility in Europe still remains to be realized. Europe is still netted in boundaries drawn in the horse and road era. In America the effects were immediate. To the United States of America, sprawling westward, it meant the possibility of a continuous access to Washington, however far the frontier travelled across the continent. It meant unity, sustained on a scale that would otherwise have been impossible.
THE STEAMBOAT: CLERMONT, 1807, U.S.A.
The steamboat was, if anything, a little ahead of the steam engine in its earlier phases. There was a steamboat, the Charlotte Dundas, on the Firth of Clyde Canal in 1802, and in 1807 an American named Fulton had a steamer, the Clermont, with British-built engines, upon the Hudson River above New York. The first steamship to put to sea was also an American, the Phœnix, which went from New York (Hoboken) to Philadelphia. So, too, was the first ship using steam (she also had sails) to cross the Atlantic, the Savannah (1819). All these were paddle-wheel boats and paddle-wheel boats are not adapted to work in heavy seas. The paddles smash too easily, and the boat is then disabled. The screw steamship followed rather slowly. Many difficulties had to be surmounted before the screw was a practicable thing. Not until the middle of the century did the tonnage of steamships upon the sea begin to overhaul that of sailing ships. After that the evolution in sea transport was rapid. For the first time men began to cross the seas and oceans with some certainty as to the date of their arrival. The transatlantic crossing, which had been an uncertain adventure of several weeks—which might stretch to months—was accelerated, until in 1910 it was brought down, in the case of the fastest boats, to under five days, with a practically notifiable hour of arrival.
