Moses Bartlett, mate, a second cousin of the captain, was 47 years old, 6 feet high, and weighed 184 pounds. He had already been as far north as Cape Sabine three times; twice as mate of my ships and once as mate of the _Neptune_, and had also spent a year on this ship in Hudson Bay in the employ of the Canadian Government. Weather-beaten, grizzled, and keen of eye, he was regarded as one of the best of the Newfoundland ice pilots. George A. Wardwell, chief engineer, was a native of Bucksport, Maine, 44 years of age, 5 feet 11 inches tall, and weighed 240 pounds. Acting as engineer in the shipyard in which the _Roosevelt_ was built and intimately employed in her construction, he was deeply interested in her proposed work and anxious to join the expedition. His phlegmatic temperament, and evident capacity for work, combined with non-use of liquor and tobacco, were all strong points in his favour. John Murphy, boatswain, was a native Newfoundlander, 31 years of age, 5 feet 11 inches tall, and weighed 165 pounds. Sailor and fisherman from the age of eighteen, he had also been as far north as Cape Sabine on the _Neptune_ and had wintered with her in Hudson Bay. Murtaugh J. Malone, assistant engineer, was a native of Portland, Maine, 49 years of age, 5 feet 7½ inches tall, and weighed 150 pounds. Dr. Louie J. Wolf, surgeon of the Expedition, was a native of Oregon, 30 years of age, 5 feet 9 inches tall, weighed 150 pounds, was a graduate of the Cooper Medical College, San Francisco, California, becoming later House Surgeon at St. Vincent’s Hospital, Portland, Oregon, and still later Assistant Attending Physician at the Cornell University Medical College, and of the outdoor medical dispensary of Bellevue Hospital. Ross G. Marvin, secretary and assistant, was a native of Elmira, N. Y., a graduate of Cornell University, 25 years of age, 6 feet tall, and weighed 160 pounds. Subsequently he had three years of naval training on board the school ship _St. Mary’s_. Charles Percy, my steward, was a native of Newfoundland, 54 years of age, 5 feet 10 inches high, and weighed 180 pounds. He had previously made a summer voyage as far north as Cape Sabine in my ship the _Diana_ in 1899, and later had spent two years with Mrs. Peary and myself at Cape Sabine, from 1900 to 1902. Subsequently he had been in my employ as resident in charge of Eagle Island. Matthew Henson, my personal attendant, was a coloured native of the District of Columbia, 39 years of age, 5 feet 6¾ inches high, and weighed 145 pounds. In my employ in one capacity or another most of the time since I took him to Nicaragua with me in 1888, and a member of all of my Arctic expeditions, his quality and capabilities were fully known.
