“Laughing misses visiting their friends for Christmas, boys returning from school for the holidays, men hastening from the far West to preside at the festive board just one week from that awful day, men and women complying with the good old fashion of uniting scattered families at the paternal hearth on the day of days, Christmas, were all mangled, maimed, destroyed, burnt, and ground to powder.... “[A]ll that is left of the car and its freight, so precious to many homes all over the land, is a mass of blackened and charred remains, in which a separate body can hardly be distinguished.”
