In a letter to boyhood friend Edward Clayton, dated Dec 3, 1840, Ruskin advised the purchase of Rogers's Italy and Rogers's Poems, and also The Rivers of France, 'in which you get sixty engravings for a sovereign; and take them to bed with you, and look at them before you go to sleep, till you dream of them' ( Works, 1.428).
In The Elements of Drawing (1857), Ruskin recommended several plates from The Rivers of France as worthy of study, singling out Rouen, looking down the River and Caudebec as particularly valuable ( Works, 15.76).
