The next day the bullfinches were bought, and Dan began to train them. They were a pair of very young birds, not a dozen days old, and the air Dan fixed upon to teach them first was "Rule, Britannia." So much for Joshua's supplemental contributions to the general fund. Now for Dan's. "Another sixpence in a piece of paper, Jo!" "That makes eighteen pence this month, Dan. Poor Susan!" "Poor Susan!" echoed Dan. Susan was very much to be pitied. Looking upon herself as her brother's destroyer, she endeavored, by offerings of sixpences as often as she could afford them, to atone for the crime--for so she now regarded it--by which she had made him a helpless cripple. These sixpences were not given openly; they were laid, as it were, upon the sacrificial altar in secret. Sometimes the altar was one of Ellen's shoes, and Ellen, when she dressed herself, would feel something sticking in her heel, and discover it to be a sixpence tightly screwed up in a piece of paper, with the words, "For Dan; from Susan," written on it; sometimes the altar was one of Dan's pocket-handkerchiefs, and the sixpence was tied up in a knot; sometimes it was a bag of bird-seed; sometimes Dan's cap. She was so imbued with a sense of guilt, that she trembled when she met Dan's eye. He was as kind and gentle to her, when he had the opportunity, as he was to all around him; and divining her secret remorse, he tried by every means in his power to lessen it. But the feeling, that, if Dan died, she was a murderess, was too deeply implanted in her to be ever removed. She lived in constant fear. She was afraid of the dark, and could not sleep without a rush-light near her bedside. Often in the night, on occasions when Dan was weaker than usual, she would creep down stairs, and listen at his bedroom-door to catch the sound of his breathing. If she did not hear it at first, the ghostly echo of the old terrible cry, "Ah-h-h-h! who killed her little brother? Ah-h-h-h!" filled the staircase and the passage with dreadful shadows; shadows that seemed to thicken and gather about her as if possessed with a desire to stifle her--and she would press her hands tightly upon her eyes so that she should not see them. Then perhaps she would open Dan's door quietly, and hearing him breathe, ever so softly, would creep up stairs again, a little more composed; always closing her door quickly, to prevent the shadows on the stairs from coming into her room.
