What does Huck do when he sees the ferry boat full of people? (CH 7-11)

Huck wakes up on Jackson's Island late the next day and hears a cannon being fired. A ferryboat filled with his friends comes down the river firing a cannon in hopes of bringing his dead body to the surface. The search parties have also set loaves of bread filled with mercury afloat, believing the mercury and bread will be attracted to his body. Knowing the loaves will be floating around the area, Huck searches for one and enjoys eating it for lunch.
