CABLE TOW'S LENGTH Gädieke says that, "according to the ancient laws of Freemasonry, every brother must attend his Lodge if he is within the length of his cable tow." The old writers define the length of a cable tow, which they sometimes called a cable's length, to be three miles for an Entered Apprentice. But the expression is really symbolic, and as it was defined by the Baltimore Convention in 1842, means the scope of a man's reasonable ability.
