This is an office of great importance and must, from the peculiar nature of our institution, have existed from its very beginning. No lodge could ever have been opened until a Tiler was appointed and stationed to guard its portals from the approach of "cowans and eavesdroppers." The qualifications requisite for the office of a Tiler are, that he must be "a worthy Master Mason." An Entered Apprentice, or a Fellow Craft, cannot tile a lodge, even though it be opened in his own degree. To none but Master Masons can this important duty of guardianship be intrusted. The Tiler is not necessarily a member of the lodge, which he tiles. There is no regulation requiring this qualification. In fact, in large cities, one Brother often acts as the Tiler of several lodges. If, however, he is a member of the lodge, his office does not deprive him of the rights of membership and in balloting for candidates, election of officers, or other important questions, he is entitled to exercise his privilege of voting, in which case the Junior Deacon will temporarily occupy his station, while he enters the lodge to deposit his ballot. This appears to be the general usage of the craft in this country.
The Tiler is sometimes elected by the lodge and sometimes appointed by the Master. It seems generally to be admitted that he may be removed from office for misconduct or neglect of duty, by the lodge, if he has been elected and by the Master, if he has been appointed.
