Altered and Improved. – The interior arrangements of Major Griswold’s office have lately undergone some change. The office of the Provost Marshal is now located in the extreme rear of the Passport Office, and the clerks employed by the Provost and Police connected with the department are all put in one room. Capt. R. M. Booker, Assistant Provost Marshal, has been assigned to duty at the corner of 9th and Broad streets. The Passport Office proper remains in the front of the building, as formerly.
