when duly aroused to mirth; and those persons were very rare, making the characters of mankind their professional study, who saw slight indications of disposition more quickly, or better enjoyed whatever gave food for quiet merriment. Once away from his counting-house, too, Walter Harding seemed to assume a second of his two natures that had before been lying dormant, and to enter into the permitted gaieties of city life with a zest that many a professed good fellow might have envied. He visited the theatre, as we have seen; went to the opera when it pleased him, not for fashion's sake, but because he liked music and was a connoisseur of singing and acting; liked a stroll in the streets with a congenial companion (male or female); could smoke a good cigar with evident enjoyment; and sometimes, though rarely, sipped a glass of fine old wine, and indulged in the freer pleasures of the table; though he was scrupulously careful of his company, and no man had ever seen his foot cross the threshold of a house of improper character. It is sufficient, in addition, at the present moment, to say that he was still a bachelor, occupying rooms in an up-town street, and enjoying life in that pleasant and rational mode which seemed to promise long continuance. Harding's companion, who has already been indicated as his opposite, was markedly so in personal appearance, at least. He was two or three inches shorter than Harding, and much stouter, displaying a well-rounded leg through the folds of his loose pants of light-gray Melton cloth, and being quite well aware of that advantage of person. He had a smoothly rounded face, with a complexion that had been fair until hard work, late hours, and some exposure to the elements, had browned and roughened it; brown hair, with an evident tendency to curl, if he had not worn it so short on account of the heat of the season, that a curl was rendered impossible; a heavy dark brown moustache, worn without other beard; a sunny hazel eye that seemed made for laughter, and a full, red, voluptuous lip that might have belonged to a sensualist; while the eye could really do other things than laughing, and the lip was quite as often compressed or curled in the bitterness of disdain or the earnestness of close thought, as employed to express any warmer or more sympathetic feeling.
