"Good-by!" said the supposed Kit, in a low tone, for he feared that the difference in his voice would be recognized. But Mr. Bickford had no suspicions. He was anxious to get started, for he and his wife were always in bed by this time ordinarily. So the team started, and Achilles Henderson, suppressing a laugh, strode away to the circus cars, which were already being prepared for a midnight journey to the next place. It may be explained here that the circus of to-day generally owns its own cars, which are used for the conveyance of all connected with it, their luggage, the tents, the animals, and all the paraphernalia of the show. As soon as the show is ended, the canvas men set to work to take down and fold up the tents. All the freight is conveyed to the cars, and the razorbacks, already referred to, set about loading them. The performers, ticketmen, and candy butchers seek their berths in the sleeping cars and are often in the land of dreams before the train starts. While Mr. Bickford was driving in the darkness to Oakford with the supposed Kit on the back seat, the real Kit was in his berth in the circus cars, preparing for a refreshing night's rest. CHAPTER XVIII. MR. BICKFORD'S MORTIFYING DISCOVERY. Mr. Bickford was in excellent spirits. He had enjoyed the evening, and although he had been compelled to disburse a dollar for two circus tickets, a sum which to him seemed large, he was disposed to acknowledge that he had received his money's worth. Besides, and this seemed to him the greatest triumph of all, he had recovered his runaway apprentice, or thought he had. He inwardly resolved that Kit should smart for his past insubordination, though he had not yet decided in what way he would get even with him. The unexpected submissiveness shown by Kit elated him, and confirmed him in the idea he had long entertained that he could manage boys a good deal better than the average of men. "Talk about hard cases," he said one day to his wife. "I'd like to see the boy that can get the start of Aaron Bickford. He'll have to get up unusually airly in the mornin'." Mr. Bickford felt a little like crowing over his captive, and turned his head partly round to survey the boy on the back seat. Fortunately for William the darkness was so great that there was small chance of his detecting the imposture. "I reckon you didn't expect to be ridin' back to Oakford along of me this evenin'," he observed. "No, sir," muttered William in a voice scarcely audible. "Ho, ho, you feel kind of grouty, eh?" said the blacksmith. "Well, I ain't much surprised. You thought you could have your own way with Aaron Bickford, but you're beginnin' to see your mistake, I reckon?" "Yes, sir," replied the supposed Kit, in a meek voice. "Ho, ho! That's the way boys ginerally come out when they try to buck agin' their elders. Not but you might have succeeded with some men, but you didn't know the man you had to deal with this time."
