John H. Caswell

John Henry Caswell was a mining engineer of ability and an accomplished mineralogist; he was likewise a successful merchant, a generous friend, a lover of books and their makers, a student of ecclesiastical and secular affairs, a devout churchman and charged with weighty church interests. He was a fine type of the best New Yorker. Eminently social, his company was sought by seven clubs, but this was the one he mostly frequented during the twenty-eight years of membership; he was sixty-three [sic: sixty-two] when stricken down. He was a graduate of Columbia, for thirty-three years a vestryman of Trinity, for all his manhood a working citizen. Those who survive him here have felt him to be one of the inner circle, a man to trust and love.
