Important reports from Washington.
We received intelligence by telegraph from Manassas yesterday, said to have been brought by passengers, to the effect that an announcement appeared in the Baltimore Sun of Saturday last, that Gen. Scott had resigned, and that Secretaries Seward, Cameron, and Blair, had all withdrawn from Lincoln's Cabinet. This information was communicated to us by two correspondents, and while it may appear like vague speculation to sign any cause for such an explosion at the Federal headquarters, the report is that it was caused by McClellan's refusal to make an attack on our forces, which was the policy advocated by the four officials above named. We decline making any further comment, in the absence of a confirmation of the statement, and give it to our readers as we received it.
