market and industrial town, southeastern South Australia, some 250 miles (400 km) by road southeast of Adelaide. Founded in 1871, it was named for the wife of George Glen, an early settler. The locality, which has much drained swampland, supports sheep, cattle, and grains. Limestone is quarried, and pine forests based at Snuggery and Mount Barr supply paper, timber, and cellulose mills. Crayfish, caught off the coast (10 miles 【16 km】 west), are processed at Millicent, which is the terminus for a rail line from the city of Mount Gambier. At nearby Wyrie Swamp the world's oldest known barbed spears have been discovered, as have the oldest boomerangs yet found in Australia. Pop. (2006) 5,550.
