[25] CHAPTER IV THE BOOKS THE town of Crowfield was built on a swift-flowing river with a waterfall, which gave it strong water-power. So the houses were easily fitted with electricity. Even the old Corliss mansion was up to date in that respect, at least. This was why Aunt Nan had been able to carry out her liking for queer devices and unexpected mechanical effects, as Mr. Griggs, the carpenter, explained when he came to make more hospitable the front hall. He chuckled over the moving chair, the secret of which was a spring concealed under one of the brass nail-heads.

Dr. Corliss had just reached out his hand for the sugar. Suddenly the table center began slowly to revolve, and the sugar bowl retreated from his hand as if by magic. “Well, I never!” said the Doctor. “This is a new kind of butler’s assistant!” [27]“It makes me feel like Alice in Wonderland!” exclaimed Mary. “It is
