From the Richmond Examiner, 8/6/1862, p. 2, c. 6
GREANOR’S FACTORY, on Cary street, between Eighteenth and Nineteenth streets, has been selected as the future location of the office of the Assistant Provost Marshal, Castle Godwin, the guard-house, and all the other appurtenances coming under the jurisdiction of that officer. The greater facility for the transaction of business will thus be secured by the fact that all the departments will here be under one roof.
