Aunt Jo's Scrap Bag, Volume 6 by Louisa May Alcott

Freddy sat thinking on the seat under the trees. It was a wide, white seat, about four feet long, sloping from the sides to the middle, something like a swing; and was not only comfortable but curious, for it was made of a whale's bone. Freddy often sat there, and thought about it for he was very much interested in it, and nobody could tell him any thing of it, except that it had been there a long time.

"Poor old whale, I wonder how you got here, where you came from, and if you were a good and happy creature while you lived," said Freddy, patting the old bone with his little hand.
