A "lewis" is a Freemason's son, who has not yet been initiated into Freemasonry. In stonemasonry, a lewis is an iron cramp that is forced into a cavity of a stone to enable the lifting or lowering of that stone. It is symbol of strength, as a son is to his father. A Lewis is granted privileges under Scottish Constitutions where the son of a Master Mason can be initiated at the age of eighteen rather than twenty-one, and receives priority for admittance.
