We entered the palace at Biberich, which, without being larger than usual, is an edifice well worth viewing. We could not but compare this abode with the President's house, and certainly, so far as taste and elegance are concerned, the comparison is entirely to the disadvantage of us Americans. It is easy to write unmeaning anathemas against prodigal expenditures, and extorting the hard earnings of the poor, on such occasions, but I do not know that the castle of Biberich was erected by any means so foul. The general denunciation of everything that does not happen to enter into our own system, has no more connexion with true republicanism than cant has to do with religion. Abuses of this nature have existed beyond dispute, and the public money, even among ourselves, is not always honestly or prudently expended; but these are the errors inseparable from human nature, and it is silly to quarrel with all the blandishments of life until we can find faultless substitutes. The simple fact that a nation like our own has suffered an entire generation to go by with its chief magistrate living in a house surrounded by grounds almost as naked as a cornfield, while it proves nothing in favour of its economy, goes to show either that we want the taste and habits necessary to appreciate the privation, (as is probably the case), or the generosity to do a liberal act, since it is notorious that we possess the means. The gardens of Biberich are extensive and beautiful. We are proofs ourselves that they are not reserved, in a niggardly spirit, for the exclusive uses of a few, nor in truth are those of any other prince in Europe where we have been. The interior of the house is much ornamented by a very peculiar marble that is found in the duchy, and which produces a good effect. A circular hall in the centre of the building, surmounted by a dome, is rather striking, from having a colonnade of this material. The family was here, and the preparations were making for dinner in one of the rooms; the whole style of the domestic economy being that of a nobleman of liberal means. The house was very quiet, and we saw but few menials, though we met two of the children, accompanied by a governess, in the grounds. Biberich and the castle, or palace, stand immediately on the banks of the river, which, between Bingen and Mayence, is straggling and well covered with islands, having an entire breadth of near half a mile. The effect, when seen from the neighbouring heights, is not unlike that of a lake.
