the town of Frederick has gotten back into Virginia, possibly with
valuable information.

When, on the evening of the 10th, there comes the startling news that
"Jeb" Stuart, with all his daring gray raiders at his back, has leaped
the Potomac at Williamsport, and is galloping up the Cumberland Valley
around McClellan's right, the provost-marshal is convinced that the bold
dash is all due to information picked up under his very nose in the
valley of the Monocacy. If he ever had the faintest doubt of the justice
of his suspicions as to "Doctor Warren's" complicity, the doubt has been
removed. Already, at his instance, a secret-service agent has visited
Hastings, and wires back the important news that the doctor left there
about the 25th of September, and has not returned. On the 11th he is
rejoiced by a telegram from Washington which tells him that, acting on
his advices, Doctor Warren had been found, and is now under close
surveillance at Willard's.

Then it is time for him to look out for his own movements. Having leaped
into the Union lines with all his native grace and audacity, the
cavalier Stuart reposes a few days at Chambersburg, placidly surveying
the neighborhood and inviting attack. Then he rides eastward over the
South Mountain, and the next heard of him he is coming down the
Monocacy. McClellan's army is encamped about Sharpsburg and Harper's
Ferry. He has but few cavalry, and, at this stage of the war, none that
can compete successfully with Stuart. Not knowing just what to do
against so active and calmly audacious an opponent, the Union general is
possibly too glad to get rid of him to attempt any check. To the vast
indignation and disappointment of many young and ardent soldiers in our
lines, he is apparently riding homeward unmolested, picking up such
supplies as he desires, paroling such prisoners as he does not want to
burden himself with, and exchanging laughing greetings with old friends
he meets everywhere along the Monocacy. At Point of Rocks, whither our
provost-marshal and Colonel Putnam are driven for shelter, together with
numerous squads of convalescents and some dozen stragglers, there is
arming for defence, and every intention of giving Jeb a sharp fight
should he attempt to pick up supplies or stragglers from its sturdy
garrison. Every hour there is exciting news of his coming, and, with
their glasses, the officers can see clouds of dust rising high in air
far up the valley. Putna
