Curtiss aimed the book at schools and Sunday schools and assembled twenty bits of Christmas lore to teach a proper observance. She includes, of course, the Nativity story, but other parts of yesterday's Christmas will be much less familiar to modern readers. The song, "White Christmas," hadn't been written yet, and the expression meant something more than snow. People gave white gifts to symbolize purity. Children might have had visions of sugarplums, but the book includes the unsweetened versions of two weepers from Hans Christian Anderson: "The Little Match Girl" and "The Fir Tree." (The tree learns too late to appreciate Christmas -- on the bonfire afterward.) And little Tom has to learn he is lucky to receive new skates for Christmas, even if they're the wrong brand. The book brings back great-grandfather's Christmas as a gift for today's worriers. Christmas always came with problems. But it always came, anyway.
