From the Rappahannock lines.
The failure of the Central train to reach this city last evening leaves us without any important information from the line of the Rappahannock. All the reports we have concur in representing the outrages of the army under Pope as intolerable.--Upon the negroes the recent orders have had a most deplorable effect, and they are said to have become insolent beyond forbearance. Some days ago the coachman of a gentleman named Somerville, in Culpeper county, walked into his master's chamber, arrayed himself in his best suit of clothes, took his watch and chain, returned to the parlor, and impudently told his master that for the future he might drive his own coach. Cases are reported where the negro women have attempted to slap the jaws of their mistresses, and it is quite common for them to dress in their mistresses clothes, put on their jewelry, and leave them in daylight, with the unpleasant assurance that they are going to play the piano for the ‘"Northern gentlemen."’
