ON completing the first volume of their work, the Editors cannot withhold their acknowledgments for the distinguished encouragement they have received in an undertaking which is immediately dependent on the favourable opinion and liberal dispositions of the public. The unprecedented support which they have obtained in a few months, renders the establishment of at least one literary journal, in our country, on a broad and permanent basis, no longer problematical. Already the number of subscribers to this publication in the Northern and Middle States amounts to nearly three thousand,—— three fourths of whom are citizens of the State of New-York. But the AMERICAN MONTHLY MAGAZINE and CRITICAL REVIEW is intended for general circulation, and addresses itself to national patronage. The experience of the Editors assures them that this appeal will not be in vain. There is not a State, nor a Territory in the Union from which they have not received subscriptions. They trust that their exertions will secure not only a continuance, but an increase of favour. That they may be enabled to give a greater quantity of light reading without curtailing the other departments of the work, they contemplate adding another sheet, in another year, to each Number, to be devoted to miscellaneous selections of an amusive character.
