Once in his office, or, as he called it on his signboard, "Dental Parlors," he took off his coat and shoes, unbuttoned his vest, and, having crammed his little stove full of coke, lay back in his operating chair at the bay window, reading the paper, drinking his beer, and smoking his huge porcelain pipe while his food digested; crop-full, stupid, and warm. By and by, gorged with steam beer, and overcome by the heat of the room, the cheap tobacco, and the effects of his heavy meal, he dropped off to sleep. Late in the afternoon his canary bird, in its gilt cage just over his head, began to sing. He woke slowly, finished the rest of his beer—very flat and stale by this time—and taking down his concertina from the bookcase, where in week days it kept the company of seven volumes of "Allen's Practical Dentist," played upon it some half-dozen very mournful airs.
