Read the excerpt from twelve years a slave below: "about two o'clock in the afternoon, i heard the last of the hounds. probably they did not cross the bayou. wet and weary, but relieved from the sense of instant peril, i continued on, more cautious and afraid, however, of the snakes and alligators than i had been in the earlier portion of my flight. now, before stepping into a muddy pool, i would strike the water with a stick. if the waters moved, i would go around it, if not, would venture through." in 150 words, identify the sensory details in this passage and their effect on the passage.
