Ida B - pronounced ''eedabee'' and only ever ''eyedah'' without the B when she's in trouble - lives an idyllic life on a beautiful farm with its own orchard, brook and mountain which isn't really a mountain, ''but hill is just too tiny a word for it''. Ida B tried school, but didn't like it, so her indulgent parents teach her at home and are making a fine job of it, because she passes her annual test with flying colours. Given a great deal of freedom and often left to her own devices, Ida B spends her time with Rufus the dog and Lulu the cat. She talks to the trees and they talk right back. She formulates plans and sends miniature rafts down the brook to which she attaches notes that say ''If this raft reaches the ocean, will you please let us know? The Ida B Applewood Construction Company''.
