Weird & Interesting science, take 2

[Mamorien]

Either my elementary-school library or one of the shelves at the back of a classroom had the first sequel, Stowaway to the Mushroom Planet, but I've never actually read the original, and until I went wiki-walking, I had no idea there'd been four more books of Chuck and David's adventures after those two. (My childhood was mostly marked by reading books as my parents, teachers, and other Duly Constituted Authorities made them available. I skipped from The Marvelous Land of Oz to Tik-Tok of Oz because the children's section of Gulfport Public Library gave the latter pride of display one day; I read the rest of Baum's Famous Fourteen in nothing you could call order, unless you happened to be Discord or Sheogorath.)
