What causes Huck's new appreciation of life on the raft? "2 or 3 days and nights went by; I reckon I might say they swum by..."
Huck has just witnessed the death of Buck, one his close friends, who is killed in a senseless duel between the Grangerfords and Shepherdsons. This shocking event is something new for Huck and he is glad to get back to the peace and quiet of the raft. This continues Twain's contrast between life on the land and life on the river. The land represents civilization and all the evils that accompany it. The river, however, is peaceful and calm---a place of rest and comfort. There are no feuds, guns, or slave hunters on their raft so Huck and Jim can relax and enjoy nature.
