Through the long hot weeks preceding the sailing of the _Roosevelt_, he worked indefatigably looking after the assembling and delivery of the countless essential items of our outfit, until he, Bartlett, and myself were nearly exhausted.

On the northern voyage he was always willing and ready, whether for taking an observation on deck or stowing cargo in the hold.

When the Eskimos came aboard, his good humor, his quiet directness, and his physical competence gained him at once their friendship and respect.

From the very first he was able to manage these odd people with uncommon success.
Later, when face to face with the stern problems of life and work in the arctic regions, he met them quietly, uncomplainingly, and with a steady, level persistence that could have but one result, and I soon came to know Ross Marvin as a man who would accomplish the task assigned to him, whatever it might be.

The tidal and meteorological observations of the expedition were his particular charge, while, during the long dark winter night, his mathematical training enabled him to be of great assistance in working out problems of march formation, transportation and supplies, and arrangements of the supporting parties.
