What did the note in Hermione's hand say when she was found petrified in Harry Potter and the Chamber of Secrets?

The note simply said the word, "pipes." Harry Potter and his friends, Hermione Granger and Ron Weasley, were attempting to discover the truth of the legendary Chamber of Secrets, and the monster guarding it. Hermione had realized that the monster must be a basilisk, a rare and very dangerous snake-like beast that had been using the pipes to travel about Hogwarts.
