The narrator had a small idea that was growing, but she was interrupted by a barrier--a place she could not go: "Thought--to call it by a prouder name than it deserved--had let its line down into the stream. It swayed, minute after minute, hither and thither among the reflections and the weeds, letting the water lift it and sink it, until--you know the little tug--the sudden conglomeration of an idea at the end of one's line: and then the cautious hauling of it in, and the careful laying of it out? Alas, laid on the grass how small, how insignificant this thought of mine looked; the sort of fish that a good fisherman puts back into the water so that it may grow fatter and be one day worth cooking and eating. I will not trouble you with that thought now, though if you look carefully you may find it for yourselves in the course of what I am going to say. But however small it was, it had, nevertheless, the mysterious property of its kind--put back into the mind, it became at once very exciting, and important; and as it darted and sank, and flashed hither and thither, set up such a wash and tumult of ideas that it was impossible to sit still. It was thus that I found myself walking with extreme rapidity across a grass plot. Instantly a man's figure rose to intercept me. Nor did I at first understand that the gesticulations of a curious-looking object, in a cut-away coat and evening shirt, were aimed at me. His face expressed horror and indignation. Instinct rather than reason came to my help; he was a Beadle; I was a woman. This was the turf; there was the path. Only the Fellows and Scholars are allowed here; the gravel is the place for me. Such thoughts were the work of a moment. As I regained the path the arms of the Beadle sank, his face assumed its usual repose, and though turf is better walking than gravel, no very great harm was done. The only charge I could bring against the Fellows and Scholars of whatever the college might happen to be was that in protection of their turf, which has been rolled for 300 years in succession, they had sent my little fish into hiding." [...] Here the narrator has the idea to look at texts from Milton and Thackeray in the library to expand on an idea, but is blocked: "here I was actually at the door which leads into the library itself. I must have opened it, for instantly there issued, like a guardian angel barring the way with a flutter of black gown instead of white wings, a deprecating, silvery, kindly gentleman, who regretted in a low voice as he waved me back that ladies are only admitted to the library if accompanied by a Fellow of the College or furnished with a letter of introduction. That a famous library has been cursed by a woman is a matter of complete indifference to a famous library. Venerable and calm, with all its treasures safe locked within its breast, it sleeps complacently and will, so far as I am concerned, so sleep for ever. Never will I wake those echoes, never will I ask for that hospitality again, I vowed as I descended the steps in anger."
