While at the 'Blue Bell' John gradually dropped his algebra and mathematics, and began to read ghost-stories. The reason of his leaving the 'sciences called pure' was the discovery that the further he proceeded on the road the more he saw his utter incapacity to understand and to master the subjects. His friend and guide, John Turnill,--subsequently promoted to a post in the excise--was equally unable to throw light into the darkness of _plus_ and _minus_, and after a few last convulsive struggles to get through the 'known quantities' into the unknown regions of _x_, _y_, and _z_, he gave it up as a hopeless effort. The spare hours henceforth were devoted to studies of a very different kind, namely, fairy tales and ghost stories. Under the roof of the 'Blue Bell' no other literature was within his reach, and he was quite content to draw temporary nourishment from it. Scarcely any books but these highly spiced ones, stuffed in the pack of travelling pedlars, ever found their way to Helpston. There was 'Little Red Riding-hood,' 'Valentine and Orson,' 'Sinbad the Sailor,' 'The Seven Sleepers,' 'Mother Shipton,' 'Johnny Armstrong,' 'Old Nixon's Prophecy,' and a whole host of similar 'sensation' stories, printed on coarse paper, with a flaming picture on the title-page. John Clare scarcely knew that there were any other books than these and the few he had seen at Glinton school in existence; he had never heard of Shakespeare and Milton, Thompson and Cowper, Spenser and Dryden; and, therefore, with the natural eagerness of the young mind just awoke to its day dreams, eagerly plunged into the new realm of fancy. The effect soon made itself felt upon the ardent reader, fresh from his undigested algebraic studies. He saw ghosts and hobgoblins wherever he went, and after a time began to look upon himself as a sort of enchanted prince in a world of magic. He had no doubt whatever about the literal truth of the stories he read; the thought of their being mere pictures of the imagination not entering his mind for a moment. It was natural, therefore, that he should come to the conclusion that, as the earth had been, so it was still peopled with fairies, dwarfs, and giants, with whom it would be his fate to come into contact some time or other. So he buckled his armour tight, ready to do battle with the visible and invisible world.
