L.m. Montgomery said this quote

Walter looked about him lingeringly and lovingly. This spot had always been so dear to him. What fun they all had had here lang syne. Phantoms of memory seemed to pace the dappled paths and peep merrily through the swinging boughs–Jem and Jerry, bare-legged, sunburned schoolboys, fishing in the brook and frying trout over the old stone fireplace; Nan and Di and Faith, in their dimpled, fresh-eyed childish beauty; Una the sweet and shy, Carl, poring over ants and bugs, little slangy, sharp-tongued, good-hearted Mary Vance–the old Walter that had been himself lying on the grass reading poetry or wandering through palaces of fancy. They were all there around him–he could see them almost as plainly as he saw Rilla–as plainly as he had once seen the Pied Piper piping down the valley in a vanished twilight. And they said to him, those gay little ghosts of other days, We were the children of yesterday, Walter–fight a good fight for the children of today and tomorrow.
