Alden, "They Went Around the House, Playing Under the Windows", 1908

The party now broke up for the night with the kind-hearted old custom of shaking hands. As I passed through the hall, on the way to my chamber, the dying embers of the Yule-clog still sent forth a dusky glow; and had it not been the season when "no spirit dares stir abroad," I should have been half tempted to steal from my room at midnight, and peep whether the fairies might not be at their revels about the hearth.

My chamber was in the old part of the mansion, the ponderous furniture of which might have been fabricated in the days of the giants. The room was panelled with cornices of heavy carved-work, in which flowers and grotesque faces were strangely intermingled; and a row of black-looking portraits stared mournfully at me from the walls. The bed was of rich though faded damask, with a lofty tester, and stood in a niche opposite a bow-window. I had scarcely got into bed when a strain of music seemed to break forth in the air just below the window. I listened, and found it proceeded from a band, which I concluded to be the waits from some neighbouring village. They went round the house, playing under the windows. I drew aside the curtains, to hear them more distinctly. The moonbeams fell through the upper part of the casement, partially lighting up the antiquated apartment. The sounds, as they receded, became more soft and aërial, and seemed to accord with quiet and moonlight. I listened and listened—they became more and more tender and remote, and, as they gradually died away, my head sank upon the pillow and I fell asleep.
