While Lady Lesbia was draining the cup of London folly and London care to the dregs, Lady Mary was leading her usual quiet life beside the glassy lake, where the green hill-sides and sheep walks were reflected in all their summer verdure under the cloudless azure of a summer sky. A monotonous life--passing dull as seen from the outside--and yet Mary was very happy, happy even in her solitude, with the grave deep joy of a satisfied heart, a mind at rest. All life had taken a new colour since her engagement to John Hammond. A sense of new duties, an awakening earnestness had given a graver tone to her character. Her spirits were less wild, yet not less joyous than of old. The joy was holier, deeper. Her lover's letters were the chief delight of her lonely days. To read them again and again, and ponder upon them, and then to pour out all her heart and mind in answering them. These were pleasures enough for her young life. Hammond's letters were such as any woman might be proud to receive. They were not love-letters only. He wrote as friend to friend; not descending from the proud pinnacle of masculine intelligence to the lower level of feminine silliness; not writing down to a simple country girl's capacity; but writing fully and fervently, as if there were no subject too lofty or too grave for the understanding of his betrothed. He wrote as one sure of being sympathised with, wrote as to his second self: and Mary showed herself not unworthy of the honour thus rendered to her intellect. There was one world which had newly opened to Mary since her engagement, and that was the world of politics. Hammond had told her that his ambition was to succeed as a politician--to do some good in his day as one of the governing body; and of late she had made it her business to learn how England and the world outside England were governed. She had no natural leaning to the study of political economy. Instead, she had always imagined any question relating to the government of her country to be inherently dry-as-dust and uninviting. But had John Hammond devoted his days to the study of Coptic manuscripts, or the arrow-headed inscriptions upon Assyrian tablets, she would have toiled her hardest in the endeavour to make herself a Coptic scholar, or an adept in the cuneiform characters. If he had been a student of Chinese, she would not have been discomfited by such a trifle as the fifty thousand characters in the Chinese alphabet.
