Becket wore a hair shirt under his gold and crimson, and there is much to be said for the combination; for Becket got the benefit of the hair shirt while the people in the street got the benefit of the crimson and gold. It is at least better than the manner of the modern millionaire, who has the black and the drab outwardly for others, and the gold next his heart.
