Hubert was equally invincible, but his armor was of a different kind. He had neither the power of body or mind which his brother possessed, but in his very weakness lay his greater strength. His delicate health had caused him from his earliest childhood to receive many indulgences which his brother had been taught to scorn, and he had early learned to prefer the chimney-corner and the crabbed letters of an old manuscript, to the pleasures of the chase. Had no new principle been awakened within him, he would, most probably, have become effeminate; but it was not so. The doctrines which he had learned from Lollard preaching, and the fragments he possessed of the Bible, had become a part of his very being, and endued his tender spirit with that supernatural courage which is far more difficult to conquer than mere physical bravery. His mind was so thoroughly imbued with holy thoughts and heavenly aspirations, that earth could offer him few temptations, while heaven seemed to him so near and real, that dangers were but lightly regarded. Notwithstanding all this, their prison-life began to tell upon them both. They had been so long accustomed to out-door life and abundant exercise, that the damp and confined air of their dungeon soon banished the color from their cheeks, and made them almost loathe their coarse fare. Then Kate’s quick wit showed itself to some purpose. "It is a foul shame," she said, during one of their conversations at the window, as she noticed Hubert pressing his face to the bars as though struggling to get as near as possible to the fresh morning air; "it is a foul shame to keep two such young eaglets chained to a rock. This window is not so small; if it were not for the bars, we might pass through, and you might exercise in the garden at night. Let us see: I venture these irons are none of the strongest; see how the rust has eaten them."
