City Jail. – Since the withdrawal of the former guard around the city jail and the substitution of another, the prisoners have made several attempts to escape. A few days since twenty were found engaged in a vigorous effort to get out, which was only defeated by a timely discovery. On Wednesday morning Richard Duff and Jon Orrell, charged with felony, got out by cutting through the roof.
