"smell around the wreck for Miss Hooker's remainders..."
See in text (Chapter XIII)
Twain uses personification to liken the ferryboat to someone sniffing around the wreck, like a dog. Recall that in the previous chapter Jim worried about the woman fetching a dog to catch their scents. Here, the image is repurposed to suggest that the robbers were the ones people should've been looking for and that Huck and Jim should be left alone.
