A necessary characteristic of people whose spirits are always running into extremes, is that they are generally able to pass from one change of mood to another with unusual facility. By the time Zack had exhausted Mr. Blyth’s copious stores of consolation, had partaken of an excellent and plentiful hot lunch, and had passed an hour up stairs with the ladies, he predicted his own reformation just as confidently as he had predicted his own ruin about two hours before; and went away to Kirk Street, to see that his friend Mat was at home to receive Valentine that evening, stepping along as nimbly and swinging his stick as cheerfully, as if he had already vindicated himself to his father by winning every prize medal that the Royal Academy could bestow. Seven o’clock had been fixed as the hour at which Mr. Blyth was to present himself at the lodgings in Kirk Street. He arrived punctual to the appointed time, dressed jauntily for the occasion in a short blue frock coat, famous among all his acquaintances for its smartness of cut and its fabulous old age. From what Zack had told him of Mat’s lighter peculiarities of character, he anticipated a somewhat uncivilized reception from the elder of his two hosts; and when he got to Kirk Street, he certainly found that his expectations were, upon the whole, handsomely realized. On mounting the dark and narrow wooden staircase of the tobacconist’s shop, his nose was greeted by a composite smell of fried liver and bacon, brandy and water, and cigar smoke, pouring hospitably down to meet him through the crevices of the drawing-room door. When he got into the room, the first object that struck his eyes at one end of it, was Zack, with his hat on, vigorously engaged in freshening up the dusty carpet with a damp mop; and Mat, at the other, presiding over the frying-pan, with his coat off, his shirt sleeves rolled up to his shoulders, a glass of steaming hot grog on the chimney-piece above him, and a long pewter toasting-fork in his hand. “Here’s the honored guest of the evening arrived before I’ve swabbed down the decks,” cried Zack, jogging his friend in the ribs with the long handle of the mop.
