What is a metaphor in chapter 31 of huckleberry finn

"Shut in like a tunnel"

"One morning, when we was pretty well down the State of Arkansaw, we

come in sight of a little one-horse town in a big bend; so we tied up

about three-quarters of a mile above it, in the mouth of a crick which

was shut in like a tunnel by the cypress trees, and all of us but Jim

took the canoe and went down there to see if there was any chance in

that place for our show."

"whooping and yelling like an Injun"

"Boggs comes a-tearing along on his horse, whooping and yelling like

an Injun, and singing out: 'Cler the track, thar.  I'm on the

waw-path, and the price uv coffins is a-gwyne to raise."

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
