I distinctly recollect the evening when these verses were suggested in 1818. It was on the road between Rydal and Grasmere, where Glow-worms abound. A Star was shining above the ridge of Loughrigg Fell, just opposite. I remember a critic, in some review or other, crying out against this piece. "What so monstrous," said he, "as to make a star talk to a glow-worm!" Poor fellow! we know from this sage observation what the "primrose on the river's brim was to him."
