In The Heathen, by Jack London, the narrator speaks of some Kanaka man, Otoo, whom he had met on a schooner:
And this I know: I lived a straighter and better man because of Otoo. I cared little for other men, but I had to live straight in Otoo's eyes. Because of him I dared not tarnish myself. He made me his ideal, compounding me, I fear, chiefly out of his own love and worship and there were times when I stood close to the steep pitch of hell, and would have taken the plunge had not the thought of Otoo restrained me. His pride in me entered into me, until it became one of the major rules in my personal code to do nothing that would diminish that pride of his.
Naturally, I did not learn right away what his feelings were toward me. He never criticized, never censured; and slowly the exalted place I held in his eyes dawned upon me, and slowly I grew to comprehend the hurt I could inflict upon him by being anything less than my best.
For seventeen years we were together; for seventeen years he was at my shoulder, watching while I slept, nursing me through fever and wounds--ay, and receiving wounds in fighting for me. He signed on the same ships with me; and together we ranged the Pacific from Hawaii to Sydney Head, and from Torres Straits to the Galapagos. We blackbirded from the New Hebrides and the Line Islands over to the westward clear through the Louisades, New Britain, New Ireland, and New Hanover. We were wrecked three times--in the Gilberts, in the Santa Cruz group, and in the Fijis. And we traded and salved wherever a dollar promised in the way of pearl and pearl shell, copra, beche-de-mer, hawkbill turtle shell, and stranded wrecks.
Now I found that "blackbird" can mean "to engage in the slave trade especially in the South Pacific", but he has said that "had to live straight"! So how can this be a straight act?
