Every well-constructed Lodge-room should be provided with two doors--one on the left hand of the Senior Warden, communicating with the preparation room; the other on his right hand, communicating with the Tiler's apartment.
The former of these is called the Inner Door, and is under the charge of the Senior Deacon; the latter is called the outer Door, and is under the charge of the Junior Deacon. In a well- furnished Lodge, each of these doors is provided with two knockers, one on the inside and the other on the outside; and the outside door has sometimes a small aperture in the center to facilitate communications between the Junior Deacon and the Tiler. This, however, is a modern innovation, and its propriety and expediency are very doubtful. No communication ought legally to be held between the inside and the outside of the Lodge except through the door, which should be opened only after regular alarm duly reported, and on the order of the Worshipful Master. Brother Mackey here describes the common practice in the United States of America, but the arrangement he advocates is by no means universal, Brother Clegg reporting instances found abroad where he entered at the left of the Senior Warden.
