and inadequate navigational tools (although Byrd would use this experience in preparing for his attempt to reach the North Pole the following year). The expedition is noted for the successful demonstration of SW radio in communications from the Arctic Region. In September 1926 MacMillan led a group of explorers which included three women and five scientists to Sydney, Nova Scotia. The team spent several months beforehand collecting flora and fauna in Labrador and Greenland. He believed it was possible that the ancient ruins off Sculpin Island, twenty miles from Nain, Labrador, are the remains of a Norse settlement 1,000 years old. On the side bordering the mainland MacMillan found what he considered the vestiges of ten or twelve houses. He estimated the age of the dwellings to be hundreds of years old according to the lichens which partially covered their foundations. However MacMillan could not say for certain if these had been built by Vikings. According to Inuit tradition the "stone igloos" were constructed by men who came from the sea in ships. Inuit called the site Tunitvik, meaning the place of the Norseman. MacMillan said the strongest argument that the Sculpin dwellings were of Viking origin was their resemblance to those he found in Greenland the previous year. World War II MacMillan was placed on the Naval Reserve Honorary Retired List with the rank of lieutenant commander on his 64th birthday in 1938. Despite being past retirement age, he volunteered for active duty with the Navy during World War II. On May 22, 1941, he transferred the Bowdoin to the Navy for the duration of the war and served as her initial commanding officer before being transferred to the Hydrographic Office in Washington, DC. He was promoted to the rank of commander on June 13, 1942. Later life After the war, MacMillan continued his trips to the Arctic, taking researchers north and carrying supplies for the MacMillan-Moravian School he established in 1929. From 1937 onward, Miriam MacMillan joined her husband on 9 Arctic expeditions as part of his crew. She took thousands of photographs, films, Inuit art artifacts, and audio recordings of Inuit, which she later organized and curated for the Peary-MacMillan Arctic Museum. In 1939, MacMillan is pictured in a portrait photograph taken by Miriam MacMillan on the Bowdoin, in his Captain's hat, holding a puppy named Kahda.
