Robert heard a rattling of bark over his head, but he knew that it was a squirrel scuttling up the trunk of the tree, and pausing now and then to examine the strange invaders of his forest.
"Do you see the squirrel, Dave ?" he asked.
"Yes, he's about twenty feet above you now, sitting in a fork.

He's a fine big fellow with a bushy tail curved so far over his back that it nearly touches his head.

He has little red eyes and he's just burning up with curiosity.

The firelight falls on him in such a way that I can see.
Perhaps he has never seen a man before.

Now he's looking at you, Robert, trying to decide what kind of an animal you are, and forming an estimate of your character and disposition." "You're developing your imagination, Dave, but since I saw what you said and did in Quebec I'm not surprised." "Encouraged by your motionless state he's left the fork, and come a half dozen feet down the trunk in order to get a better look at you.
