Twain was referring to ANNE OF GREEN GABLES. I have the quote in a secondary source: The Dial, February 1986. It is the PBS guide that just happened to be promoting both ANNE and the four-hour HUCK FINN remake. Clemens sent a copy of the book to Frances Nunnally in October of 1908. See Gribben's MARK TWAIN's LIBRARY: A RECONSTRUCTION, vol. I, pg. 480. In a letter to Francis Wilson, Clemens states "In 'Anne of Green Gables' you will find the dearest and most delightful child since the immortal Alice." KB
