Old Abe makes an Excursion.
--The New York Herald's
Washington letter says:
‘
The President, accompanied by
Secretary Seward and
Thurlow Weed, made a tour of observation down the
Potomac to-day.
Early this morning the
Pawnee was moored off the city of
Alexandria, so that her guns and mortars will command the town.
She has several of
James' riled cannon on board, which will throw grape, shell, hot shot or solid into any part of the town, or far beyond; into the camp of any army that may be so imprudent as to pitch their tents in the suburbs of the city.--A messenger who came in from
Alexandria this evening says there are not one hundred and fifty troops in the place, and they are not all armed.
It is true that the Secession flag still floats over the town.
Senator Wade, upon observing it with a glass from the
President's room yesterday, expressed his regret to
Mr. Lincoln that it should be tolerated, to which
Mr. L. replied that.
‘" he did not think it would wavethere long."’
