I had never made friends with a porcupine,—he is too briery a fellow for intimacies,—but now with a small stick I began to search him gently, wondering if, under all that armor of spears and brambles, I might not find a place where it would please him to be scratched. At the first touch he rolled himself together, all his spears sticking straight out on every side, like a huge chestnut bur. One could not touch him anywhere without being pierced by a dozen barbs. Gradually, however, as the stick touched him gently and searched out the itching spots under his armor, he unrolled himself and put his nose under my foot again. He did not want the beechnut; but he did want to nose it out. Unk Wunk is like a pig. He has very few things to do besides eating; but when he does start to go anywhere or do anything he always does it. Then I bent down to touch him with my hand.

That was a mistake. He felt the difference in the touch instantly. Also he smelled the salt in my hand, for a taste of which Unk Wunk will put aside all his laziness and walk a mile, if need be. He tried to grasp the hand, first with his paws, then with his mouth; but I had too much fear of his great cutting teeth to let him succeed. Instead I touched him behind the ears, feeling my way gingerly through the thick tangle of spines, testing them cautiously to see how easily they would pull out.

The quills were very loosely set in, and every arrowheaded barb was as sharp as a needle. Anything that pressed against them roughly would surely be pierced; the spines would pull out of the skin, and work their way rapidly into the unfortunate hand or paw or nose that touched them. Each spine was like a South Sea Islander’s sword, set for half its length with shark’s teeth. Once in the flesh it would work its own way, unless pulled out with a firm hand spite of pain and terrible laceration. No wonder Unk Wunk has no fear or anxiety when he rolls himself into a ball, protected at every point by such terrible weapons.

The hand moved very cautiously as it went down his side, within reach of Unk Wunk’s one swift weapon. There were thousands of the spines, rough as a saw’s edge, crossing each other in every direction, yet with every point outward. Unk Wunk was irritated, probably, because he could not have the salt he wanted. As the hand came within range, his tail snapped back like lightning. I was watching for the blow, but was not half quick enough. At the rustling snap, like the voice of a steel trap, I jerked my hand away. Two of his tail spines came with it; and a dozen more were in my coat sleeve. I jumped away as he turned, and so escaped the quick double swing of his tail at my legs. Then he rolled into a chestnut bur again, and proclaimed mockingly at every point: “Touch me if you dare!”

I pulled the two quills with sharp jerks out of my hand, pushed all the others through my coat sleeve, and turned to Unk Wunk again, sucking my wounded hand, which pained me intensely. “All your own fault,” I kept telling myself, to keep from whacking him across the nose, his one vulnerable point, with my stick.

Unk Wunk, on his part, seemed to have forgotten the incident. He unrolled himself slowly and loafed along the foot of the ridge, his quills spreading and rustling as he went, as if there were not such a thing as an enemy or an inquisitive man in all the woods.

He had an idea in his head by this time and was looking for something. As I followed close behind him, he would raise himself against a small tree, survey it solemnly for a moment or two, and go on unsatisfied. A breeze had come down from the mountain and was swaying all the tree-tops above him. He would look up steadily at the tossing branches, and then hurry on to survey the next little tree he met, with paws raised against the trunk and dull eyes following the motion overhead.

At last he found what he wanted,—two tall saplings growing close together and rubbing each other as the wind swayed them. He climbed one of these clumsily, higher and higher, till the slender top bent with his weight towards the other. Then he reached out to grasp the second top with his fore paws, hooked his hind claws firmly into the first, and lay there binding the tree-tops together, while the wind rose and began to rock him in his strange cradle.

Wider and wilder he swung, now stretched out thin, like a rubber string, his quills lying hard and flat against his sides as the tree-tops separated in the wind; now jammed up against himself as they came together again, pressing him into a flat ring with spines sticking straight out, like a chestnut bur that has been stepped upon. And there he swayed for a full hour, till it grew too dark to see him, stretching, contracting, stretching, contracting, as if he were an accordion and the wind were playing him. His only note, meanwhile, was an occasional squealing grunt of satisfaction after some particularly good stretch, or when the motion changed and both trees rocked together in a wide, wild, exhilarating swing. Now and then the note was answered, farther down the ridge, by another porcupine going to sleep in his lofty cradle. A storm was coming; and Unk Wunk, who is one of the wood’s best barometers to foretell the changing weather, was crying it aloud where all might hear.

So my question was answered unexpectedly. Unk Wunk was out for fun that afternoon, and had rolled down the hill for the joy of the swift motion and the dizzy feeling afterwards, as other wood folk do. I have watched young foxes, whose den was on a steep hill side, rolling down one after the other, and sometime varying the programme by having one cub roll as fast as he could, while another capered alongside, snapping and worrying him in his brain-muddling tumble.
