Then suddenly the laboratory was hushed by a curious, braying noise. It was the demonstrator. He was at the blackboard ready to begin the day's instruction, and it was his custom to demand silence by a sound midway between the "Er" of common intercourse and the blast of a trumpet. The girl in brown slipped back to her place: it was immediately in front of Hill's, and Hill, forgetting her forthwith, took a notebook out of the drawer of his table, turned over its leaves hastily, drew a stumpy pencil from his pocket, and prepared to make a copious note of the coming demonstration. For demonstrations and lectures are the sacred text of the College students. Books, saving only the Professor's own, you may--it is even expedient to--ignore. Hill was the son of a Landport cobbler, and had been hooked by a chance blue paper the authorities had thrown out to the Landport Technical College. He kept himself in London on his allowance of a guinea a week, and found that, with proper care, this also covered his clothing allowance, an occasional waterproof collar, that is; and ink and needles and cotton, and such-like necessaries for a man about town. This was his first year and his first session, but the brown old man in Landport had already got himself detested in many public-houses by boasting of his son, "the Professor." Hill was a vigorous youngster, with a serene contempt for the clergy of all denominations, and a fine ambition to reconstruct the world. He regarded his scholarship as a brilliant opportunity. He had begun to read at seven, and had read steadily whatever came in his way, good or bad, since then. His worldly experience had been limited to the island of Portsea, and acquired chiefly in the wholesale boot factory in which he had worked by day, after passing the seventh standard of the Board school. He had a considerable gift of speech, as the College Debating Society, which met amidst the crushing machines and mine models in the metallurgical theatre downstairs, already recognised--recognised by a violent battering of desks whenever he rose. And he was just at that fine emotional age when life opens at the end of a narrow pass like a broad valley at one's feet, full of the promise of wonderful discoveries and tremendous achievements. And his own limitations, save that he knew that he knew neither Latin nor French, were all unknown to him.
