Mr. Day borrows many of his instructive details from Rousseau: the juggler, who taught Emile the use of magnets by means of an artificial duck, conspires with Mr. Barlow and Harry to teach the uninformed Tommy Merton; but there are other experiments more practical than Rousseau’s, which suggest actual experience and the co-operation of Mr. Edgeworth. These alternate with short tales introduced according to what Mr. Day calls the “natural order of association”; but their effect is to weaken the genuine interest of the enveloping story. “The Gentleman and the Basket Maker”[89] gains nothing by the Good Boy’s elocution; Leonidas shakes himself free from Mr. Barlow’s patronage.
