Interesting Correspondence

The Boston Courier publishes the following profoundly interesting and affectingcorrespondence, communicated to it by a valued friend : IXTRODUCTORY LETTER. Mr Dear Sir - The following correi,pondence between Gen. McCIellan and Bishop Whipple, of Minnesota, took place immediately after the battle of Antictam. The Bishop, who had known the General for years, allowed me to take a copy of the correspondence, but not for publication. Since the removal of Gen. McClellan, however, there would seem to be no impropriety in the publication, and possibly it may throw sorae light upon the secrót of his power over the army, gaining their love and inspiring their confide nee.
