POSTSCRIPT.

From the vicinity of our press to the enemy's stations, we have not heretofore thought ourselves justified in making public the recent operations of our military force, &c. The enemy however is evidently now well informed on this subject without our aid, and our scruples are removed.

The enemy's vessels are still in sight, being unable, from head winds, to move down the river, if they were so disposed. Meanwhile heavy batteries have been erected on both sides of the Potomac some miles below these vessels, near which they must pass to rejoin their squadrons. These batteries are posted and manned by our gallant seamen and flotilla-men, under Rodgers, Porter, Perry, and other brave spirits, and covered on each side by large bodies of our militia and volunteer forces, who are detached for the service.

From these preparations we hope to see an arrogant foe chastised in his descent with his plunder from Alexandria.

This morning a bomb vessel from off Alexandria anchored, out of reach of our cannon shot, off the White House (some miles below Mount Vernon, on the Virginia side) where a body of our men are stationed, and amused them for some hours with throwing bomb-shells at them, which however had no other effect than to accustom the militia to disregard this sort of annoyance.

The enemy appears to have burnt two or three small vessels off Alexandria in the course of yesterday.

From Benedict we learn, that in the course of Thursday night and yesterday morning all the vessels in the Patuxent got under way, and proceeded down that river, destination unknown.
