No need to tell about that evening, for every child knows what a Christmas tree is better than we can describe it, so we will skip into the next morning when the boys' joke came off.

The young folks usually slept late after their unwonted revelry by night, but, strange to relate, the lads were early astir. In fact, Mary, the cook, saw several small ghosts whisking up the back-stairs when she went down to kindle her fire, and curious sounds were heard in attic and cellar, store-room and closets.

Something very exciting was going on, and the elders were evidently in it, for, though several mammas were heard to cry out when certain mysterious things were shown them, they never said a word, but looked up bits of gay ribbon without a murmur; while the papas enjoyed the fun and lent a hand in the most delightful manner.
