On this qnestion the Mew York World of tho 27th speaks as foilowg : The JEvening Post. has a novel and curious theory by which it accounts for the non-success of every General who has íailed niñee the war commenced. - It is, in briei, thut every Union office r who does nol believe in negro equality s bound to l)e defeuted. This whimsi cally i'ïinat icril notion the Post venti ates evjry lime our firmies aro óafpated. When Gen. Halleck issned order No. ij the Post pronounced liirn little butter than an ass. Gen. Gilmore, the sumo uuthority slated, did not ciipture Charlt'Mlon becauso he hüd no fait h m negro soldiers ; Gen. Seymour lost the buttJe ol ülnstee because he was not un aboltiionist ; and now, to cap the cliiiiax, Banks has been dt-fuated Upan the Red River bi-'caiise he did oot f olio w the tnisoegenation platform out to the very letter in his government of of Louisiana. It irt passinu; ntran;e that these unreaonine: ttinatics cniinot see that a man's sentiinents on abstract topics have nothlnjr vvhutever to do with his (irnctical abiliUes in the field. "Stcnewall" Juckson and Lee vvill ulways rank as good Generáis, nnd yet both are on record HU believers in the divinity of slavery, and it is possible that there may be earnest abolitiimists in our niMTiies who are good General, though we do not know who they are.
