GUILLAUMIN ET CIE, the well known Parisian publishers, are about to add to their _Collection des Principaux Economistes_ several American works in this department. One volume, at least, will be devoted to Henry C. Carey's masterly compositions, with a preface and commentaries; another volume will be given to the Free Trade party, and will embrace the best things of Mr. Walker, Mr. Raguet, Mr. Cardozo, Henry Middleton, Dr. Wayland, &c.; and essays by Mr. Phillips, Horace Greeley, and other Protectionists, will probably constitute another. The _Collection_ now embraces Quesnay, Turgot, Dupont Nemours, Le Tronne, the Says, Galliani, de Montyon, Condillac, Lavoisier, Adam Smith, Hume, Ricardo, Malthus, Bentham, and a dozen more. The only American name in the list is that of Franklin quoted in the first volume of the _Melanges_, edited by Daire and Molinari. * * * * * JOSEPH GALES, of the _National Intelligencer_, has lately published several leading articles of such compactness and completeness, such weight and dignity, as distinguish only the greatest compositions in philosophy and upon affairs. The intellectual force acting through the press of this country is habitually underrated. There are a dozen journals here which may be advantageously compared with any in Europe, with the single exception of the _Times_. It would perhaps seem invidious to point them out, from the greater number that are conducted with ability and energy; but it will not be objected by any one who has the right to express an opinion in the case, if we say that Mr. Gales is of the first rank of public men who have ever influenced or illustrated the course of events by written eloquence or argument. The leading articles from his hand which in the last twenty-five years have appeared in the National Intelligencer, would fill many volumes; and if collected and so submitted to one view, they would astonish by their variety, by the extraordinary resources of information which they evince, by their soundness of logic, elevation of sentiment, and uniform adaptation to their several purposes. If they lack the pungent wit, and fiery energy of phrase, and adroitly venomous spirit of "Junius," they have, with their nobler calmness and uniform candor, a far wider sweep, a subtler apprehension of consequences, and a more statesmanlike aim and capacity. The diction of "Junius" was calculated to arrest attention, by its glitter and strength, and by its freshness; for it was in style, after all, that he was most creative, and since his style has by imitation become familiar, it is for the mystery of their authorship only that his works have continued eminence. As materials for history, and as suggestive guides of policy, we have in American literature very few works so important as the leading articles of Joseph Gales would constitute, fitly arranged, and illustrated by such notes as he could
