The Postmaster General on Friday made a contract with Robert Orrick, of Winchester, for conveying the mails from that town to Leesburg, Virginia, and intermediate points twice a week, at five hundred and twenty-five dollars per annum. The accepted bidder in this case is the first colored man to whom a contract for carrying the mails has been awarded since the Department was organized. Of his own free will and accord, finding no line of stages on the above road, he came forward with commendable enterprise and industry, and tendered a proposal for the service. —Chronicle.
