(f) Lack the Centre of a Semaphore Type Communications System

While the American Indians communicated through the medium of smoke signals, Lack was the centre of a unique communications system, involving the display of sheets on a clothes line, up to the mid 19th century. The communications were between three branches of the Cotter family, one resident in Lack (Egan's Hill) another in Coolmeen and the third in Clonmore north of Lisheen. The Cotters in Lack had a view of the other two households and all three could communicate by the hanging of sheets on a clothes line in a certain formation and in the interpreting the formation by the other party. We have no information on how long the practice continued but it died with the Cotter families.
