The manner of investigation in regard to a missing relative or friend is as follows: As soon as a person disappears from home, the nearest relative, on learning of the missing person, goes to police headquarters and makes application to the "Missing Bureau" for information. The age, height, build; whiskers, if any; color of eyes, dress, hair; the place where last seen, the habits and disposition of the person, are given to the inspectors, and Officer McWatters makes proper entries on his register, which he keeps for that purpose, of all these facts. The personal description of the missing one is compared with the returns made by the Morgue every twenty-four hours to the police inspectors. Should the description answer to the person and clothing of any one found at the Morgue, word is at once sent to the relatives of the joyful news. Besides this, another very necessary precaution is taken to find the person or persons missing. Cards are printed, five or six hundred in number, and sent to all the police offices on special duty in the different metropolitan precincts, with instructions to the captains to have his men make active and energetic search for the person.
