12. Cf. Milton, _P. L._ iv. 245: "Where the unpierc'd shade Imbrown'd the noontide bowers;" Pope, _Eloisa_, 170: "And breathes a browner horror on the woods;" Thomson, _Castle of Indolence_, i. 38: "Or Autumn's varied shades imbrown the walls." According to Ruskin (_Modern Painters_, vol. iii. p. 241, Amer. ed.) there is no brown in nature. After remarking that Dante "does not acknowledge the existence of the colour of _brown_ at all," he goes on to say: "But one day, just when I was puzzling myself about this, I happened to be sitting by one of our best living modern colourists, watching him at his work, when he said, suddenly and by mere accident, after we had been talking about other things, 'Do you know I have found that there is no _brown_ in nature? What we call brown is always a variety either of orange or purple. It never can be represented by umber, unless altered by contrast.' It is curious how far the significance of this remark extends, how exquisitely it illustrates and confirms the mediæval sense of hue," etc. 14. _O'ercanopies the glade_. Gray himself quotes Shakes. _M. N. D._ ii. 1: "A bank o'ercanopied with luscious woodbine."[1] Cf. Fletcher, _Purple Island_, i. 5, 30: "The beech shall yield a cool, safe canopy;" and Milton, _Comus_, 543: "a bank, With ivy canopied." [Footnote 1: The reading of the folio of 1623 is: "I know a banke where the wilde time blowes, Where Oxslips and the nodding Violet growes, Quite ouer-cannoped with luscious woodbine." Dyce and some other modern editors read, "Quite overcanopied with lush woodbine."] 15. _Rushy brink_. Cf. _Comus_, 890: "By the rushy-fringed bank." 19, 20. These lines, as first printed, read: "How low, how indigent the proud! How little are the great!" 22. _The panting herds_. Cf. Pope, _Past._ ii. 87: "To closer shades the panting flocks remove." 23. _The peopled air_. Cf. Walton, _C. A._: "Now the wing'd people of the sky shall sing;" Beaumont, _Psyche_: "Every tree empeopled was with birds of softest throats." 24. _The busy murmur_. Cf. Milton, _P. R._ iv. 248: "bees' industrious murmur." 25. _The insect youth_. Perhaps suggested by a line in Green's _Hermitage_, quoted in a letter of Gray to Walpole: "From maggot-youth through change of state," etc. See on 31 below. 26. _The honied spring_. Cf. Milton, _Il Pens._ 142: "the bee with honied thigh;" and _Lyc._ 140: "the honied showers."
