"A diller, a dollar, A (ten o'clock) scholar, What makes you come so soon? You us'd to come at ten o'clock, and now you come at noon."
I know of absolutely no traditional collections of this item, and I have no idea what it means. But reading it in Baring-Gould, I remember the first two lines from somewhere, with a fragment of a tune (plus, according to Cyn Collins, _West Bank Boogie_, Triangle Park, 2006, there was in the Sixties and Seventies a folk music bar/club at the University of Minnesota called the "Ten O'Clock Scholar"), so I am very tentatively including the piece in the Index. - RBW
