TILE - A Lodge is said to be tiled when the necessary precautions have been taken to prevent the approach of unauthorized persons; and it is said to be the first duty of every Freemason to see that this is done before the Lodge is opened. The words to tile are sometimes used in the same sense as to examine, as when it is said that a visitor has been tiled, that is, has been examined. But the expression is not in general use, and does not seem to be a correct employment of the term. The English expression close tyled means that a Lodge is formally secluded against all persons not fully qualified and authorized to enter.
