military establishment was quite enough to deal with the Indians. And to crown all, the American people were thoroughly familiar with the principle of representation, having practised it on a grand scale for four centuries in England, and for more than a century in America. The governments of the thirteen states were all similar, and the political ideas of one were perfectly intelligible to all the others. It was essentially fallacious, therefore, to liken the case of the United States to that of ancient Rome. [Sidenote: Influence of railroad and telegraph upon perpetuity of the American Union.] But there was another feature of the case which was quite hidden from the men of 1783. Just before the assembling of the first Continental Congress James Watt had completed his steam-engine; in the summer of 1787, while the Federal Convention was sitting at Philadelphia, John Fitch launched his first steamboat on the Delaware River; and Stephenson's invention of the locomotive was to follow in less than half a century. Even with all other conditions favourable, it is doubtful if the American Union could have been preserved to the present time without the railroad. But for the military aid of railroads our government would hardly have succeeded in putting down the rebellion of the southern states. In the debates on the Oregon Bill in the United States Senate in 1843, the idea that we could ever have an interest in so remote a country as Oregon was loudly ridiculed by some of the members. It would take ten months--said George McDuffie, the very able senator from South Carolina--for representatives to get from that territory to the District of Columbia and back again. Yet since the building of railroads to the Pacific coast, we can go from Boston to the capital of Oregon in much less time than it took John Hancock to make the journey from Boston to Philadelphia. Railroads and telegraphs have made our vast country, both for political and for social purposes, more snug and compact than little Switzerland was in the Middle Ages or New England a century ago.
