Captain Delano’s nature was not only benign, but familiarly and humorously so. At home, he had often taken rare satisfaction in sitting in his door, watching some free man of color at his work or play. If on a voyage he chanced to have a black sailor, invariably he was on chatty and half-gamesome terms with him. In fact, like most men of a good, blithe heart, Captain Delano took to negroes, not philanthropically, but genially, just as other men to Newfoundland dogs.
Delano's "singular good nature" is not exempt from the dehumanizing aspects of American racism endemic of the setting of the work (or, indeed, of the time of its composition). Alongside his ease with assisting Benito's ship (and thus the slave trade that it facilitates), Delano's perception of African peoples stereotypes them as 'animalistic' and simple. That is, he participates in the 18th-19th century of perception that contributes to the perception of Africans and those of African descent as subhuman.
