When any one of these nobles is questioned as to the nature of his claim to the enjoyment of so large a portion of the produce of the land, without doing any thing to earn or deserve it, he says that it is a _vested right_; that is, that he has a right to claim and take a certain portion of the proceeds of the toil of the _present_ generation of laborers, because his forefathers claimed and took a similar portion from theirs. And the one monarch, whose ancestors succeeded in overpowering or crowding out the others, claims his right to rule on the same ground. Thus, in the progress of ages, by a strange commutation, robbery and plunder, when systematized, and extended, and established on a permanent basis, become legitimacy, and the divine right of kings. In America there is no such division of the fruits of industry between those who do the work and a class of idle nobles, and soldiers, and priests, who do nothing but consume the proceeds of it. There every man possesses the full fruit of his labor, except so far as he himself joins with his fellow-citizens in setting apart a portion for the purposes of public and general utility. This is the reason why such immense numbers of laboring men are every year leaving Germany and emigrating to America. But to return to the Rhine. Of course, just so fast and so far as the smaller chieftains were conquered and dispossessed, and the country came into the hands of a smaller number of greater princes, the old castles became useless. Besides, when rules and laws, instead of surprises and violence, became the means by which contributions were levied, it was no longer necessary to have strongholds on high hills to come down from, when a vessel or a traveller was coming by, and to retreat to with the booty when the plunder had been taken. A great number of these old castles have, therefore, gone to decay; for they were generally built too high on the hills and rocks to be convenient as dwellings for peaceable men. A few of the largest and strongest of them were retained as fortresses; and those that were retained have been greatly enlarged and strengthened in their defences in modern times, so that some of them are now the greatest and strongest fortresses in the world. Others, that were built in tolerably accessible situations, or which commanded an unusually beautiful view, were retained and kept in repair, and are used now as the summer residences of wealthy men. The rest were suffered gradually to go to decay, and the ruins and remains of them are seen crowning almost every remarkable height all along the river. Some of these ruins are still in a very good state of preservation, so that in going up to explore them you can make out very easily the whole original plan of the edifice. You can find the turret, with the remains of the stairs which led up to the watchtower, and the kitchen, and the hall, and the armory, and the stables. In others, there is nothing to be seen
