The Harper's Ferry Affair.
--A letter from Hagerstown, dated on the 19th, says:‘ "We were all set astir this morning, about twenty minutes after seven, by the appearance of United States soldiers, about fifty in round numbers, dragging themselves up towards the depot. They were the most haggard individuals I have seen for some time, soiled and muddy, and so tired that they were scarcely able to drag their arms after them. Their intention was to get on the cars and go to Carlisle. The history of their adventures last night at Harper's Ferry I presume you are acquainted with already. We could get but little out of them; some dropped hints of what they had done last night, and some said if 'they had their say they would be in some place else.' They all appeared quite uneasy, as they came 'too late for the cars,' and not knowing what kind of reception they would receive were anxious to be off as soon as possible. The poor devils were too tired to walk, as they had come all the way from the Ferry since 11 o'clock, so they hired hacks and went to Chambersburg to take the noon train for Carlisle. The poor Lieutenant, who, by the way, was so knocked up that he could scarcely walk, and had thrown away his sword, as it impeded his flight, told Captain Nesbitt that he had destroyed fifteen thousand stand of arms and did as much damage as they could before the Virginians chased them off."’
