Letter from a Baltimore boy.
--We have printed a letter written by a lad of thirteen years in Baltimore, to a relative in this city, which though not of so late a date as our last advices is interesting as showing the spirit which animates the youth of the Monumental City. He says "We are being cruelly ground later the iron heel of Yankee oppression.--We have no police and as soon as the Legislature passes the Ordinance of Secession, the members have no other hope but to be sent to Fort de Lafayette, when the oath of allegiance of the Lincoln Government will be administrator to the citizens of the State, unless they are speedily relieved, or rather rescued, by the confederate troops. ‘"When Maryland is called on, she will be up to time, and I suppose we can furnish thirty or forty more regiments when the army crosses the Potomac."’There is much more in the letter, but it re- briefly to incidents of Federal tyranny which our readers are familiar. If all the of Baltimore had the pluck of that boy. The guns of Fort McHenry would not long from them into submission.
