264. Collegisse juvat: The full sentence, in the first ode of Horace, reads, "Curriculo pulverem Olympicum collegisse juvat." (It is a pleasure to have collected the dust of Olympus on one's chariot wheels.) The allusion is to the Olympic games, the most celebrated festival of Greece. Lowell puns upon the word _collegisse_ with his own coinage, which may have the double meaning of _going to college_ and _collecting._ 272. Blinding anguish: An allusion to the death of his little daughter Blanche. See _The Changeling, The First Snow-fall,_ and _She Came and Went_. _THE OAK_ 11. Uncinctured front: The forehead no longer encircled with a crown. 13-16. There is a little confusion in the figures here, the cathedral part of the picture being a little far fetched. 40. Mad Pucks: Puck is the frolicsome, mischief-making spirit of Shakespeare's _Midsummer Night's Dream._ 45. Dodona grove: The grove of oaks at Dodona was the seat of a famous Greek oracle, whose responses were whispered through the murmuring foliage of the trees. _BEAVER BROOK_ Beaver Brook at Waverley was a favorite resort of Lowell's and it is often mentioned in his writings. In summer and winter it was the frequent goal of his walks. The poem was at first called _The Mill_. It was first published in the _Anti-Slavery Standard_, and to the editor, Sidney H. Gay, Lowell wrote:--"Don't you like the poem I sent you last week? I was inclined to think pretty well of it, but I have not seen it in print yet. The little mill stands in a valley between one of the spurs of Wellington Hill and the main summit, just on the edge of Waltham. It is surely one of the loveliest spots in the world. It is one of my lions, and if you will make me a visit this spring, I will take you up to hear it roar, and I will show you 'the oaks'--the largest, I fancy, left in the country." 21. Undine: In mythology and romance, Undine is a water-spirit who is endowed with a soul by her marriage with a mortal. The _race_ is the watercourse conducted, from the dam in an open trough or "penstock" to the wheel. 45. In that new childhood of the Earth: This poem was written a few weeks after the _Vision of Sir Launfal_ was published, and it therefore naturally partakes of its idealism. _THE PRESENT CRISIS_
