A secret cáucuq of CoDgrosíiona] ultmiats was held in Washington on Monday eveníng, for the purpi.se of; orgamzing an oppoeition (o the constitutiona] policy the President has determinad to pursue in putting down : the rebellion. About twenty mercbera participated, and thortgh correspondente and outsiders wi-ro oxcluded, the proeeediogs ;ire venülated in the New York Times. Pomeroy, of Kansas, presideá; and McPherson, ol Pennsylvania, was Clerk. Thad Stevens made a long speech, proclaitned genera] etnanuipatioQ, and pitched into Oom. McOldlan liko a thousand of brick, which was only " whipping the , duyil round the stump," or, in other vrords, :i very oautioua way of "gctling a lick" at "Oíd Abe." D'.ven, of New York, replied; clenied the right of' the caueus to establish a war policy, and offered resnlutions aflirming the Pbiladelpliia and Chicago platforms, and protesting against the right of a OongVessional ConVenticn to add to or take from those statements of principio. Maiiy other speeches were made, btit the caucii9 adjourned to Wednesdny evening without coming io a vote on Piven's resolutions. - Republican papers have been accustomed to deiionnce as ' secessionista," '; traitors," etc, all persons - espec rally if they were democrats - who have called in quéstion governrnont measures and governmental policy ; and, we may, therefore, expeet(? that thee same journals will fiercely rebuke these Congressional agitators. If it is a crime for a private ci'izen or journalist to dissent from specific governrnent mensures; is it any Icss a crime for members of CongiesH to orffiinize an opposition to the Gorernment, and attempt to compel the President to adopt a policy he considera unnecessary, unwise, and uWOTistitatiün'il, even though such members are Kopnblieans ? Who will answer us ? jif" On Monday the Senate rosolved tí) appoint a committee to investigate tbe causes of defeat to our annies at. Bell Kun, Ball's Bluft, "Wilson's Creek, and Tjfxington. As man}r of the Senators participatcd in the Buil Run aff :iir - especially in the run - and are eupposed to know all about the canses of that defeat, Ihey shonld have confincd the investigation, to the oiher three reverses. And then, we think the investigation at tliis stage, should be k'ft 'o the war department, and that no gootl will come from a politícheongrepeionöl oommitteo of investigation.
