I rather like the story [name I can't recall] where he was isolated on an island back in the long ago past and left to die there.
How I Spent My Christmas Vacation by Nan Smith. But I'm sure that wasn't the end of the story, now was it?

Debbie, my daughter loves C&H, but it's been a while since I've read it. The "Boink" sounded like Calvin, but I wasn't sure about "Scientific Progress", so I doubt I would have recognized it until you mentioned them at the end. Also, "boink" sounds more like an error (to my ears), so it would've made more sense for "Scientific Progress Went Boink". LOL.
