This kind of music was naturally popular. Such a service relieves the tedium of a Sunday afternoon, and has something of the charm a dog finds in pursuing his own tail. Some of the members of the class turned their heads and their vocal mouths towards the door when Tom came in, but in the midst of this jangle of voices singing different portions of the same air most of them had all they could do to keep their time by waving their heads or thumping their toes on the puncheon floor, while they alternately looked at their books and at Bryant, who thrashed away with his whip, his lips seeming to say, though the words were inaudible in the general din: "Up, down, right, left, up," as he perpetually made right angles in the air. Rachel was in the act of drawing the word "boy" to the full length of a long note with a hold after it, but she looked up long enough to recognize the new arrival; then she dropped her eyes to the book again and gave the most severe attention to Bryant and the square notes thereafter, not once looking at Tom to the end. From this unwonted absorption in her music, Tom inferred that Rachel had somehow heard of his misconduct and was offended. But her charms enchanted him more than ever now that they were receding from him, and with a characteristic resolution he determined not to give her up without a sharp endeavor to regain his lost ground. When the "singing" "let out," Tom availed himself of the first moment of confusion, while Rachel stood apart, to ask permission to go home with her, in the well-worn formula which was the only polite and proper word to use for the purpose; for it is strange how rigidly certain exact forms were adhered to among people where intercourse was for the most part familiar and unconventional. "May I see you safe home?" he asked, as he had often asked before, but never before with trepidation. "No," said Rachel, with an evident effort, and without looking at Tom's face. Such an answer is technically known as "the sack" and "the mitten," though it would take a more inventive antiquary than I to tell how it got these epithets. But it was one of the points on which the rural etiquette of that day was rigorous and inflexible, that such a refusal closed the conversation and annihilated the beau without allowing him to demand any explanations or to make any further advances at the time. Tom was not of the sort easily snuffed out. He had to ride past Rachel's house, and it would be an addition to his disappointment that everybody would see his discomfiture. So he answered.
