But the willingness to sacrifice on the part of the man who wrote
the following was so touching that I could not accept: "I have a
father, a mother, brothers and sisters, dear friends and a lucrative
position, and yet I will sacrifice all to become one of your crew."

fellow who, to show me how necessary it was that I should give him a
chance, pointed out that "to go in the ordinary boat, be it schooner
or steamer, would be impracticable, for I would have to mix among
and live with the ordinary type of seamen, which as a rule is not a
clean sort of life."
