“I'll not leave you,” said he, in a voice scarce louder than a whisper: “there's my hand upon it,” and he wrung in his strong grasp the unresisting fingers of the old man. “That's a promise, father, and now let us speak no more about it.” “I'll get to my bed, Mark,” said the O'Donoghue, as he pressed his hands upon his throbbing temples. It was many a day since anything like emotion had moved him, and the conflict of passion had worn and exhausted him. “Good-night, my boy--my own boy;” and he fell upon the youth's shoulder, half choked with sobs. As the O'Donoghue slowly ascended the stairs, towards his bedroom, Mark threw himself upon a chair, and buried his face in his hands. His sorrow was a deep one. The resolve he had just abandoned, had been for many a day the cherished dream of his heart--his comfort under every affliction--his support against every difficulty. To seek his fortune in some foreign service--to win an honourable name, even though in a strange land, was the whole ambition of his life; and so engrossed was he in his own calculations, that he never deigned a thought of what his father might feel about it. The poverty that eats its way to the heart of families seldom fails to loosen the ties of domestic affection. The daily struggle, the hourly conflict with necessity, too often destroy the delicate and trustful sense of protection that youth should feel towards age. The energies that should have expanded into homely affection and mutual regard, are spent in warding off a common enemy; and with weary minds and seared hearts the gentler charities of life have few sympathies. Thus was it here. Mark mistook his selfishness for a feeling of independence; he thought indifference to others meant confidence in himself--and he was not the first who made the mistake. Tired with thinking, and harassed with difficulties, through which he could see no means of escape, he threw open the window, to suffer the cool night air to blow upon his throbbing temples, and sat down beside the casement, to enjoy its refreshing influence. The candles had burned down in the apartment, and the fire, now reduced to a mere mass of red embers, scarce threw a gleam beyond the broad hearth-stone. The old tower itself flung a dark shadow upon the rock, and across the road beneath it, and, except in the chamber of the sick boy, in a distant part of the building, not a light was to be seen.
