Messrs. Arnold Harris, McGraw and Ed.
--We learn that several members of Congress and other influential and prominent gentlemen are in favor of the release of these individuals. Certain correspondence of Mr. Enris', written in the month of April to friend in New Orleans, proving him to be a friend to the South, has been laid before the authorities. It has never been pretended that Harris did anything more than commit an indiscretion and place himself in an equivocal attitude by approaching our lines without a flag of truce, seeking indirectly for the body of Secretary Cameron's broths.--His letter to General Beauregard was couched in terms ill-calculated to forward him in the business upon which he had come, and his ‘"neutral"’ position therein claimed was not easily admitted, seeing he came from the enemy's country on the errand he did.But being a resident of the District of Columbia, and proving himself to have been a Southerner in sentiment long before any suspicion attached to him, his case does not wea the aspect it did at first. Technically, he violated the usages of nations at war; but having approached our lines, openly, for the purpose of addressing the General commanding, he will probably regain his freedom through the intervention of those who knew his printed sentiments respecting the Lincoln Government when it had only commenced these sets of usurpation and despotic authority which have characterized its conduct down to the present time.
An example having been set, and the dignity of this Government vindicated, we may let Mr. Harris go.
