	My dear People.
	My dear Bagginses and Boffins, and my dear Tooks and Brandybucks,
and Grubbs, and Chubbs, and Burrowses, and Hornblowers, and Bolgers,
Bracegirdles, Goodbodies, Brockhouses and Proudfoots.  Also my good
Sackville Bagginses that I welcome back at last to Bag End.  Today is my
one hundred and eleventh birthday: I am eleventy-one today!"
