How completely does the mighty drama now passing before our eyes on the great theatre of Europe, justify these hold and sagacious predictions! A great revolution has just taken place in France, and a distinguished prince, out of the regular line of succession, has been invited to the throne, _on condition_ of governing according to the constitution prescribed by the representatives of the popular will. Belgium is doing the same thing. Devoted Poland has attempted it. Italy is in confusion,--and Germany disturbed and uneasy;--so that, it seems already no longer to be in the power of any conspiracy of kings or Congresses, to maintain permanently in Western Europe, a government not essentially founded on free institutions and principles. We will only add, that Mr. Webster has, on hardly any other occasion, entered into the discussion of European politics; and the consequence has been, that, if this speech has found less favour at home than some of his other efforts, it is one, that has brought him great honour abroad; since, besides being printed wherever the English tongue is spoken, it has been circulated through South America, and published in nearly every one of the civilized languages of Europe, including the Spanish and the Greek. In April, 1824, he took a part in the great discussion of the tariff question; and his speech on that occasion, as well as the one he delivered on the same subject in May, 1828, are both given in the volume before us. But the whole matter is so fresh in the recollections of the community, and Mr. Webster's constant defence of a tariff adapted to the general interests of the country, encouraging alike the cause of American manufactures and the interests of commerce, are so well known, from the first tariff of 1816, to the present moment, that it cannot be needful to speak of them. We would remark, however, that, in the speech of 1824, two subjects are discussed with great ability;--the doctrine of exchange, and the balance of trade. Both of them had been drawn into controversy in Congress, on previous occasions, quite frequently, calling forth alternately "an infinite deal of nothing," and the crudest absurdities; but, from the period of this thorough and statesmanlike examination of them, they have, we believe, hardly been heard of in either house. The great points involved in both of them, have been considered as settled.
