Leggett", Engines of our Ingenuity by John H. Lienhard, January 31, 2014. Retrieved June 14, 2018) and later to the Firwood, which burned off the coast of Peru on December 18, 1919, with 28 persons on board, all of whom survived. ("Broadcast Station Calls With a Past" by William Fenwick, Radio Broadcast, July 1928, page 150. This source incorrectly states the ship's name as Firewood.)
