Pedagogy

   Another woman, a well-to-do plumber's widow, taught grammar and spelling. Her method was rigorous and messy. She presented great clumps of uncapitalized, misspelled, and unpunctuated words, and demanded that the clumps be put into proper sentences, meticulously punctuated and correctly spelled. She then corrected the corrections; the final document—she employed a system of different-colored inks—resembled a much-revised treaty between two semiliterate countries at war.
