“What is he doing that for?” asked Johnny Chuck, looking rather puzzled.
“Go near enough to be hit by it, and you'll understand,” said Old Mother Nature dryly. “That is his one weapon. Whoever is hit by that tail will find himself full of those little spears and will take care never to go near Prickly Porky again. Once those little spears have entered the skin, they keep working in deeper and deeper, and more than one of his enemies has been killed by them. On account of those tiny barbs they are hard to pull out, and pulling them out hurts dreadfully. Just try one and see.”
But no one was anxious to try, so Old Mother Nature paused only a moment. “You will notice that he moves that tail quickly,” she continued. “It is the only thing about him which is quick. When he has a chance, in time of danger, he likes to get his head under a log or rock, instead of putting it between his paws as he is doing now. Then he plants his feet firmly and waits for a chance to use that tail.”
“Is it true that he can throw those little spears at folks?” asked Peter.
Old Mother Nature shook her head. “There isn't a word of truth in it,” she declared. “That story probably was started by some one who was hit by his tail, and it was done so quickly that the victim didn't see the tail move and so thought the little spears were thrown at him.”
“How does he make all those little spears stand up that way?” asked Jumper the Hare.
“He has a special set of muscles for just that purpose,” explained Old Mother Nature.
“When those quills stick into some one they must pull out of Prickly Porky's own skin; I should think that would hurt him,” spoke up Striped Chipmunk.
“Not at all,” replied Old Mother Nature. “They are very loosely fastened in his skin and come out at the least little pull. New Ones grow to take the place of those he loses. Notice that he puts his whole foot flat on the ground just as Buster Bear and Bobby Coon do, and just as those two-legged creatures called men do. Very few animals do this, and those that do are said to be plantigrade. Now, Prickly Porky, tell us what you eat and where you make your home, and that will end today's lesson.”
“I eat bark, twigs and leaves mostly,” grunted Prickly Porky ungraciously. “I like hemlock best of all, but also eat poplar, pine and other trees for a change. Sometimes I stay in a tree for days until I have stripped it of all its bark and leaves. I don't see any sense in moving about any more than is necessary.”
