So Tom carried Mary about all the morning, and went to Minchampstead in the afternoon, and got three hours' good shooting; but in the evening he vanished; and his father went into Armsworth's to look for him.

"Why do you want to know where he is?" replied Mark, looking sly. "However, as you can't stop him now, I'll tell you. He is just about this time sewing up Briggs's coat-sleeves, putting copperas into his water jug, and powdered galls on his towel, and making various other little returns for this morning's favour."

"I dislike practical jokes."

"So do I; especially when they come in the form of a black dose. Sit down, old boy, and we'll have a game at cribbage."

In a few minutes Tom came in—"Here's a good riddance. The poisoner has fabricated his pilgrim's staff, to speak scientifically, and perambulated his calcareous strata."

"What!"

"Cut his stick, and walked his chalks; and is off to London."

"Poor boy," said the Doctor, much distressed.

"Don't cry, daddy; you can't bring him back again. He's been gone these four hours. I went to his room, at Bolus's, about a little business, and saw at once that he had packed up, and carried off all he could. And, looking about, I found a letter directed to his father. So to his father I took it; and really I was sorry for the poor people. I left them all crying in chorus."

"I must go to them at once;" and up rose the Doctor.
