It seems wonderful that so frail and lovely a plant has such power over human hearts. this calypso meeting happened some forty-five years ago, and it was more memorable and impressive than any of my meetings with human beings excepting, perhaps, emerson and one or two others. when i was leaving the university, professor j. d. butler said, "john, i would like to know what becomes o you, and i wish you would write me, say once a year, so i may keep you in sight." i wrote to the professor, telling him about this meeting with calypso, and he sent the letter to an eastern newspaper [the boston recorder] with some comments of his own. these, as far as i know, were the first of my words that appeared in print.
