Professor McGonagall welcomed the first-year students and guided them to the sorting ceremony, where each student would be sorted into one of Hogwarts' four houses, namely, Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. She told them about the importance of this ceremony and mentioned the House Cup. The ceremony was held in the Great Hall, a splendid dining hall, with all the school's students and teachers at present. After singing a greeting song, the sorting hat started to shout out the name of the house each student was assigned to as McGonagall called the students to put on the hat one at a time in alphabetical order. Hermione and Neville were both put in Gryffindor, and Malfoy was put in Slytherin. When it was Harry's turn, the sorting hat hesitated for a while, hearing Harry asking not to be put in Slytherin, then put him in Gryffindor. Lastly, Ron joined his new friends and his brothers at the Gryffindor table. After the sorting ceremony, Dumbledore welcomed the students with a short speech and treated them to a feast created by magic. The students chatted with each other while enjoying their dinner. Harry also talked to the ghost Nearly Headless Nick, and saw Professor Quirrell and Professor Snape for the first time. Dumbledore concluded the feast with another speech, telling the new students about the school rules. Then they sang the school song and the ceremony was dismissed. Harry and his friends followed Percy into Gryffindor’s dormitory. Harry was so tired that he fell asleep almost immediately. He had a strange dream but forgot about it the next morning.
