EN He had, however, a happy mixture of pliability and perseverance in his nature; he was in form and spirit like a supple-jack --yielding, but tough; though he bent, he never broke; and though he bowed beneath the slightest pressure, yet, the moment it was away --jerk! he was as erect, and carried his head as high as ever.
