It was Christmas morning; and Nelly March and her brother Rob were lying wide awake in their beds, wondering if it would do for them to get up and look in their stockings to see what Santa Claus had brought them. Nelly and Rob were twins; but you would never have thought so, when you looked at them, for Nelly was half a head taller than Rob, and a good deal heavier. She had always been well; but Rob had always been a delicate child. He was ill now with a bad sore throat, and had been shut up in the house for ten days. This was the reason that he and Nelly were in bed at six o'clock this Christmas morning, instead of scampering all about the house, and waking everybody up with their shouts of delight over their presents. When they went to bed the night before, Mrs. March had said: "Now, Rob, you must promise me not to get out of bed till it is broad daylight, and the house is thoroughly warm. You will certainly take cold, if you get up in the cold room."
