The other book I've been tracking down is in reference to the "Mouldiwarp." My neighboring teacher, with whom I'm teaching botany, remembers fondly a children's book about this little animal (this is the Scottish word for 'mole') and wants us to share it with our class next Monday when we do the parts of the soil. The only book I found online when searching through Amazon was The House of Ardenby E. Nesbit, originally published in 1908. In this book the children encounter a magical Mouldiwarp.
But she was certain that there was a children's book just simply called The Mouldiwarp and I'm not sure if anyone out there is familiar with this book??? Please let me know.
