We find the following in the Boston Courier of March 29th: 

’Our attention has been called to a statement in the CONTINENTAL MONTHLY MAGAZINE, to the effect, that certain interesting ‘Notes on the Gulf States,’ which have recently appeared in this paper were reproductions, with certain alterations, of letters which were printed in the Knickerbocker Magazine several years ago.  The statement made is not positive, but made with such qualifications as might lead to the inference that the comparison was not very carefully made.  We can only say, that we have had no opportunity to confer with our distant correspondent, who handed us the whole series of ‘Notes’ together, in manuscript, for publication; nor had we any reason to believe that they were ever printed before, either in whole or in part.  We can say nothing further, until we know more about the grounds for the intimation of the CONTINENTAL MONTHLY.’

We were guarded in our statement, not having at hand, when we wrote the paragraph referred to, more than three or four numbers of the Courier containing the Gulf States articles, and not desiring to give the accusation a needlessly harsh expression, knowing well that the best informed editor may have at times old literary notes passed upon him for new ones.  What we do say, is simply that several columns of the articles which appeared as original in the Boston Courier, were literal reprints from a series which appeared in the Knickerbocker Magazine in 1847.
