All Warrants issued by the Steward shall be in force for One Calendar Month from the Date thereof, and shall be returned by the Barmaster to the Steward within Six Weeks from the Date thereof, with a Memorandum or Return endorsed thereon, and signed by the Barmaster, stating when it was executed, or if from any Cause the Barmaster shall have been unable to execute it, then stating why it has not been executed; and in the latter Case the Warrant may be renewed, and Returns made from Time to Time until it is executed; and every renewed Warrant shall be in force for One Calendar Month from the Date thereof; and every Return to a renewed Warrant shall be made within Six Weeks after the Re-issuing of the Warrant, but the Omission to return any Warrant shall not make any one a Trepasser for having obeyed the same, nor shall it be necessary to state or prove any such Return in order to justify anything done in obedience to the same.
