Meanwhile Professor Binns, the ghost who taught History of Magic, had them writing weekly essays on the goblin rebellions of the eighteenth century. Professor Snape was forcing them to research antidotes. They took this one seriously, as he had hinted that he might be poisoning one of them before Christmas to see if their antidote worked. Professor Flitwick had asked them to read three extra books in preparation for their lesson on Summoning Charms. Even Hagrid was adding to their workload. The Blast-Ended Skrewts were growing at a remarkable pace given that nobody had yet discovered what they ate. Hagrid was delighted, and as part of their “project,” suggested that they come down to his hut on alternate evenings to observe the skrewts and make notes on their extraordinary behavior. “I will not,” said Draco Malfoy flatly when Hagrid had proposed this with the air of Father Christmas pulling an extra-large toy out of his sack. “I see enough of these foul things during lessons, thanks.” Hagrid’s smile faded off his face.
