Composition and Publication
	Hand is pencil, print (made prior to first use of pen and ink in April 1827). See Note on Ruskin’s Hand. Because the poem shares source material with the concluding chapters of “Harry and Lucy . . . vol. 1,” its composition can be viewed as a poetic expression of the boy’s scientific interests (see Discussion).
	Printed in Ruskin, Works, 2:254–55 n. 3; and Emerson, Genesis of Invention, 24–25. Quoted by Ruskin in Ruskin, Works, 35:56; and by Poems (4o, 1891), 1:xxi, and Poems (8o, 1891), 1:vii.
