How did Huck and Jim get off the riverboat?

Finally, Huck and Jim find the murderers' skiff. They are about to leave when they remember that they have forgotten to go through Jim Turner's belongings and get their share (before they leave him there to drown when the steamboat capsizes). When they left to go back to their partner, Huck and Jim jumped in the boat and cut the cord, not daring to even dip their oars, for fear of making noise. On the way, they encounter their old raft. They find that they amassed a fair amount of loot from the "Walter Scott" which they now put on the raft.
